OPINION AND ORDER
SHIRA A. SCHEINDLIN, District Judge.I. INTRODUCTION
This consolidated action comprises hundreds of securities class actions brought against issuers and underwriters of technology stocks that had their initial public offerings (“IPOs”) during the late 1990s. On April 2, 2009, the parties filed a Stipulation and Agreement of Settlement (“Stipulation”) that seeks to conclude eight years of litigation in 309 coordinated class actions. Plaintiffs also filed a motion for an order: (1) preliminarily approving the proposed Stipulation; (2) certifying the Settlement Classes for the purposes of the proposed Stipulation only; (3) approving the form and program of Class notice described in the Stipulation; and (4) scheduling a hearing before the Court to determine whether the proposed Stipulation should be finally approved. For the reasons stated below, plaintiffs’ motion is granted.
II. BACKGROUND
A. Plaintiffs’ Allegations
Plaintiffs’ allegations are discussed at length in a series of earlier Opinions.1 In brief, plaintiffs allege that the underwriters of hundreds of IPOs required allocants in those IPOs to purchase shares in the aftermarket, often at inflated prices, and to pay the underwriters undisclosed compensation. Additionally, the underwriters allegedly prepared analyst reports that contained inaccurate information and recommendations. Plaintiffs allege that they lost billions of dollars as a result of these manipulations and the fraudulent statements made to cover up the scheme. Plaintiffs have brought claims under both the Securities Act of 1933 (the “Securities Act”) and the Securities Exchange Act of 1934 (the “Exchange Act”).
B. Settlement Terms
On April 1, 2009, the parties entered into a settlement of the 309 cases, which is subject to this Court’s approval.2 The Stipulation provides that defendants will pay a total of $586 million (“Settlement Amount”) in exchange for plaintiffs releasing all Settled Claims against them.3 The Issuers’ Insurers *85and the Underwriters have also agreed to advance $10 million for the purposes of notice and administration costs.4 The Stipulation further provides that the Settlement Amount less any advances will be deposited into an escrow account at least fourteen days before the date of the hearing scheduled by the Court to consider final approval of the settlement.5 The parties have stipulated that final approval of the settlement in all of the actions is required.6
C. Class Certification
Plaintiffs inform the Court that the parties have stipulated to the certification in each case of the following settlement class pursuant to Rule 23(a) and Rule 23(b)(3):
[A]ll Persons who purchased or otherwise acquired any of the Subject Securities at issue in such case during the Settlement Class Period applicable to such action and were damaged thereby.
(a) Subject to the review provisions provided in Paragraph 20 [of the Stipulation],7 excluded from the Settlement Class is each Person, other than a Natural Person, that was identified as a recipient of an allocation of shares from the “institutional pot” in the IPO or Other Charged Offering of any of the 309 Subject Securities, according to a list derived from the final “institutional pot” list created at the time of each IPO or Other Charged Offering by the lead Underwriter in that Offering (“Excluded Allocants”).
(b) Also excluded from the Settlement Classes are (i) each Person that currently is or previously was a named defendant in any of the 309 Actions (hereafter “Named Defendant”), (ii) any attorney who has appeared in the Actions on behalf of a Named Defendant, (iii) members of the immediate family of any Named Defendant, (iv) any entity in which any Excluded Allocant or Named Defendant has or during any of the class periods had a majority interest, (v) the legal representatives, heirs, successors or assigns of any Excluded Allocant or Named Defendant; and (vi) any director, officer, employee, or beneficial owner of any Excluded Allocant or Named Defendant during any of the Settlement Class Periods. Notwithstanding the prior sentence, a person shall not be excluded from the Settlement Classes merely by virtue of his, her or its beneficial ownership of the securities of a publicly-traded Excluded Allocant or Named Defendant.8
In each Action, the Class Period is from the date of the IPO until December 6, 2000.9
D. Fees and Expenses
According to the proposed Notice of Pen-dency, plaintiffs’ counsel will move the Court to award attorneys’ fees not to exceed 33 1/3 percent of the Total Designation Amount in each Action.10 Plaintiffs’ counsel will also move the Court to award expenses of approximately $56 million in connection with the prosecution of the Actions plus interest.11
*86Furthermore, Plaintiffs’ Counsel estimate that Proposed Settlement Class Representatives and Lead Plaintiffs will apply to the Court for reimbursement of their reasonable time and expenses in a total amount not to exceed $4 million.12 Finally, it is estimated that an additional $27.5 million will be incurred by the Claims Administrator for the notification of the potential settlement class members and processing of claims forms.13 The amounts of fees and expenses for all Actions are listed in Schedule 2 of the Proposed Notice of Pendency.14
E. Plan of Designation and Allocation
According to the Stipulation, the Settlement Amount is to be distributed to all Authorized Claimants in accordance with the Plan of Allocation, and none shall revert to defendants under any circumstances.15 The Stipulation further provides that the Plan of Allocation is “not a necessary term of the Stipulation” and is “not a condition of this Stipulation or the Settlement that any particular Plan of Allocation be approved.”16
The proposed Plan of Allocation is set forth in the Proposed Notice of Pendency submitted by plaintiffs. According to the proposed Plan of Allocation, the $586 million Settlement Amount and interest earned will be reduced by taxes, costs, fees, and expenses to produce a “Net Settlement Fund.”17 This Net Settlement Fund will then be allocated to the Actions in proportion to the amount of potentially recoverable damages in accordance with a table of amounts as set forth in Schedule 2 of the proposed Notice of Pendency (“Net Designation Amounts”).18 In order to ensure that no case is “unfairly disadvantaged by its participation in this settlement,” each case will be allotted a “floor” or minimum Net Designation Amount of $300,000.19 This floor only applies in 35 cases, “resulting in total additional designations (to those cases) of $3,925,-139[ ] over and above the designation amounts resulting from the damage methodology.”20 The highest Net Designation Amount in the 309 cases is approximately $20 million.21
Authorized Claimants will be eligible to receive a pro rata share of the net settlement fund designated for the case or cases for which they have a claim up to the amount of their recognized losses.22 Where the Net Designation Amount for a particular case exceeds the actual amount of the recognized losses of all Authorized Claimants, the excess will “flow into a pot to be combined with excess Net Designation Amounts from all other Actions ... and will be utilized to pay underfunded [r]ecognized [cjlaims in all Actions.” 23
F. Class Representative Approvals
Plaintiffs inform the Court that in each of the 309 cases, at least one of the proposed settlement class representatives affirmatively approved the settlement.24 However, they also report that in thirty-three cases, “the lead plaintiffs are not the proposed settlement class representatives and have failed to respond to communications from counsel about the settlement.”25 In five cases, plaintiffs report that the lead plaintiff disapproved *87of the settlement.26 Nevertheless, they inform the Court that in each of the thirty-eight cases for which the lead plaintiff has either not responded or disapproved of the settlement, a class member who desires to serve as settlement class representative has approved the settlement.27
G. Notice
Notice to the class will be administered by The Garden City Group, Inc., a firm plaintiffs claim is experienced in class action settlement administration and notice procedures.28 Because the Garden City Group previously provided services on a prior proposed settlement in this case, it already maintains a database of potential class members in 298 IPO cases.29 •
Plaintiffs propose that notice be sent by first-class mail.30 For the 298 cases involved in the prior proposed settlement, the identification of the potential class members had already been accomplished.31 For the remaining eleven eases, the issuers will provide their transfer records, and the underwriter defendants will provide the records of settling trades, at no cost.32 The administrator will also notify approximately 2,000 brokers and nominee owners of the proposed settlement and request either that they provide a list of their beneficiaries or that they forward the notice on to their beneficiaries.33
Plaintiffs inform the Court that the notice administrator will also maintain a website which will allow claimants to file proofs of claim and obtain copies of the stipulation and other court filings.34 Finally, the administrator will publish the summary notice in the national editions of the Wall Street Journal, USA Today, The New York Times, and over PR Newswire within ten days of the mailing.35
III. APPLICABLE LAW
A. Preliminary Approval
Unlike settlements in ordinary suits, the settlement of a class action must by approved by the court.36 The court owes a duty to class members to ensure that the proposed settlement is “fair, reasonable and adequate.”37 In making this determination, the court’s “primary concern is with the substantive terms of the settlement;” accordingly, the court must “compare the terms of the compromise with the likely rewards of litigation.” 38 The trial judge must “apprise herself of all facts necessary for an intelligent and objective opinion of the probabilities of ultimate success should the claim be litigated.” 39 The court should not go so far as to effectively conduct a trial on the merits, but should make “findings of fact and conclusions of law whenever the propriety of the settlement is seriously in dispute.”40 The court must also scrutinize the negotiating process leading up to the settlement. “A presumption of fairness, adequacy, and reasonableness may attach to a class settlement reached in arm’s-length negotiations between experienced, capable counsel after meaningful discovery.”41
*88In determining whether a settlement is “fair, reasonable and adequate,” courts in this Circuit look to the following factors: (1) the complexity, expense and likely duration of the litigation; (2) the reaction of the class to the settlement; (3) the stage of the proceedings and the amount of discovery completed; (4) the risks of establishing liability; (5) the risks of establishing damages; (6) the risks of maintaining the class through the trial; (7) the ability of the defendants to withstand a greater judgment; (8) the range of reasonableness of the settlement fund in light of the best possible recovery; and (9) the range of reasonableness of the settlement fund to a possible recovery in light of all the attendant risks of litigation.42 Ultimately, the approval of the proposed settlement of a class action is a matter of discretion for the trial court.43 Nevertheless, a court should be mindful of the “ ‘strong judicial policy in favor of settlements, particularly in the class action context.’ ”44
B. Class Certification
1. Certification of Settlement Classes
The use of a settlement class allows the parties to concede, for purposes of settlement negotiations, the propriety of bringing the suit as a class action and allows the court to postpone formal certification of the class until after settlement negotiations have ended. The United States Supreme Court has expressly approved the use of the settlement class device, while also warning that the device raises special concerns.45 A settlement-only class must meet all the requirements of Rule 23, with one important exception: because the case will never go to trial, the court need not consider the manageability of the proceedings should the case or cases proceed to trial.46 In the settlement context, the “specifications of [Rule 23] — those designed to protect absentees by blocking unwarranted or overbroad class definitions — demand undiluted, even heightened, attention.”47
As courts and commentators have noted, when settlement occurs early in the case the parties have less information on the strengths and weaknesses of the claims, and thus the court and class members may be hampered in their ability to determine the fairness of the settlement:
Extended litigation between or among adversaries might bolster confidence that the settlement negotiations were at arm’s length. If, by contrast, the case is filed as a settlement class action or certified for settlement with little or no discovery, it may be more difficult to assess the strengths and weaknesses of the parties’ claims or defenses, to determine the appropriate definition of the class, and to consider how class members will actually benefit from the proposed settlement.48
The use of this device may also raise questions about collusion and the ability of plaintiffs’ counsel to represent the interests of the entire class.49 Thus, because of these con*89cerns, when a settlement class is certified after the terms of settlement have been reached, courts must require a “clearer showing of a settlement’s fairness, reasonableness and adequacy and the propriety of the negotiations leading to it.”50
2. Miles I and Miles II
On October 13, 2004, I issued an Opinion and Order certifying classes in each of six focus cases (the “2004 Class Certification Opinion”).51 The classes consisted of “all persons and entities that purchased or otherwise acquired the securities of [the issuer] during the Class Period and were damaged thereby, subject to various exclusions.”52 The Class Periods for the Exchange Act claims were the periods from the respective IPOs through December 6, 2000. For the Securities Act Claims, the Class Periods were limited to periods in which all tradeable shares in the market could be traced to the IPOs.53
In June 2005, the Second Circuit granted defendants’ petition for leave to appeal pursuant to Rule 23(f) of the Federal Rules of Civil Procedure. The Circuit directed the parties to address the proper standard for a class certification motion and whether the Basic presumption of reliance was appropriately extended to plaintiffs’ claims.
On December 5, 2006, the Second Circuit announced its Opinion in Miles v. Merrill Lynch & Co. (“Miles I”).54 In Miles I, the Circuit clarified the standard to be applied in class certification actions (thereby amending the previously articulated standard in this Circuit) and then applied that standard to this case.55
The court also concluded that plaintiffs “cannot satisfy the predominance requirement for a(b)(3) class action” because individual questions predominated over common questions in the areas of knowledge and reliance.56 First, the court held that plaintiffs could not take advantage of the Basic v. Levinson presumption of reliance.57 The court noted that “the market for IPO shares is not efficient,” citing the fact that no analyst reports are published during the 25-day “quiet period.”58 Second, the court ruled that many potential claimants would have known that the price was “affected by the alleged manipulation,” thereby making it difficult for plaintiffs to prove that they were ignorant of inflated prices, a prerequisite of a section 10(b) claim.59 The court noted that the classes as defined included initial IPO allocants, who were “required to purchase in the aftermarket” and who were “fully aware of the obligation that is alleged to have artificially inflated share prices.”60 It also noted plaintiffs’ admission that there was an “industry-wide understanding” of aftermarket purchases, evidenced by the knowledge of the many thousands of people employed by the institutional investors who had been parties to the tie-in agreements and by news reports and an a Securities Exchange Commission (“SEC”) Staff Legal Bulletin that had publicized such practices in 1999 and 2000.61
This appeared to close the door on any opportunity for class certification in these cases. However, on April 6, 2007, the Miles *90panel issued a decision denying rehearing of Miles I but clarifying certain points in its original opinion (“Miles II”).62 Plaintiffs had argued in their petition for rehearing that the Circuit had erred both in finding that predominance could not be satisfied and in failing to remand to this Court for evaluation of the class under the clarified standard.63 Specifically, with regard to the first point, plaintiffs argued that non-allocants who purchased shares in the aftermarket “would have relied on the market price of the shares and would have lacked knowledge of the alleged fraud ....”64
The Circuit explained that its decision in Miles I applied only to the broad class certified by this Court.65 Thus, the Circuit resolved both of plaintiffs’ arguments by observing that “[njothing in [Miles /] precludes the Petitioners from returning to the District Court to seek certification of a more modest class, one as to which the Rule 23 criteria might be met, according to the standards we have outlined.”66 The Circuit concluded, “we leave it to the Petitioners in the first instance to seek whatever relief they deem appropriate from the District Court, which can be expected to give such a request full and fair consideration.” 67
3. Standard of Review
Plaintiffs bear the burden of demonstrating — by a preponderance of the evidence^ — that the proposed class meets the requirements for class certification.68 This Court must “assess all of the relevant evidence admitted at the class certification stage’ when determining whether to grant a Rule 23 motion.”69 “[T]he obligation to make such determinations is not lessened by overlap between a Rule 23 requirement and a merits issue, even a merits issue that is identical with a Rule 23 requirement.”70 However, “in making such determinations, a district judge should not assess any aspect of the merits unrelated to a Rule 23 requirement.” 71
4. Requirements of Rule 23(a)
Rule 23 of the Federal Rules of Civil Procedure governs class certification. “ ‘Rule 23 is given liberal rather than restrictive construction, and courts are to adopt a standard of flexibility.’ ”72 To be certified, a putative class must first meet all four prerequisites set forth in Rule 23(a), commonly referred to as numerosity, commonality, typicality, and adequacy.73
The numerosity requirement mandates that the class be “so numerous that joinder of all members is impracticable.”74 Impracticable does not mean impossible; joinder may merely be difficult or inconvenient, rendering use of a class action the most efficient method to resolve plaintiffs’ claims.75 Sufficient numerosity can be presumed at a level of forty members or more.76
*91Commonality requires a showing that common issues of fact or law affect all class members.77 “Commonality does not mandate that all class members make identical claims and arguments.”78 When “common questions do predominate, differences among the questions raised by individual members will not defeat commonality.”79
“Typicality ‘requires that the claims of the class representatives be typical of those of the class, and is satisfied when each class member’s claim arises from the same course of events[] and each class member makes similar legal arguments to prove the defendant’s liability.’ ”80 Rather than focusing on the precise nature of plaintiffs’ injuries, the typicality requirement may be satisfied where “injuries derive from a unitary course of conduct by a single system.”81 A lack of typicality may be found in cases where the named plaintiff “was not harmed by the [conduct] he alleges to have injured the class”82 or the named plaintiffs’ claim is subject to “specific factual defenses” atypical of the class.83
Adequacy demands that “the representative parties will fairly and adequately protect the interests of the class.”84 “Generally, adequacy of representation entails inquiry as to whether: 1) plaintiffs interests are antagonistic to the interest of other members of the class” and 2) plaintiffs attorneys are qualified, experienced and able to conduct the litigation.”85 “[C]lass representative status may properly be denied ‘where the class representatives have so little knowledge of and involvement in the class action that they would be unable or unwilling to protect the interests of the class against the possibly competing interests of the attorneys.”86 However, the Supreme Court has “expressly disapproved of attacks on the adequacy of a class representative based on the representative’s ignorance.” 87
Finally, the courts have added an “implied requirement of ascertainability” to the express requirements of Rule 23(a).88 “[T]he requirement that there be a class will not be deemed satisfied unless the class description is sufficiently definite so that it is administratively feasible for the court to determine whether a particular individual is a member.”89 “‘An identifiable class exists if its *92members can be ascertained by reference to objective criteria.’ ”90
5. Requirements of Rule 23(b)
In addition to showing that the proposed class satisfies the four prerequisites of Rule 23(a), plaintiffs must show that the class is “maintainable” under Rule 23(b). A class satisfies this requirement if it in fits into one of the three alternative categories delineated by Rule 23(b), subdivisions (1), (2), and (3). In the case at bar, plaintiffs move for class certification pursuant to subdivision (b)(3).
Under Rule 23(b)(3), certification is appropriate where “questions of law or fact common to the members of the class predominate over any questions affecting only individual members,” and the court finds that class litigation “is superior to other available methods for the fair and efficient adjudication of the controversy.”91 Generally, the “ ‘predominance inquiry tests whether proposed classes are sufficiently cohesive to warrant adjudication by representation.’ ”92 The Second Circuit has observed that this subdivision
encompasses those cases in which a class action would achieve economies of time, effort, and expense, and promote uniformity of decision as to persons similarly situated, without sacrificing procedural fairness or bringing about other undesirable results.93
“Regardless of whether [an action] as a whole satisfies Rule 23(b)(3)’s predominance requirement,” courts may employ Rule 23(c)(4) to certify a class on a particular issue.94
In determining whether the class action mechanism is the most “fair and efficient” method of resolving a case, courts must consider the following four nonexclusive factors: (1) class members’ interest in maintaining individual actions; (2) “the extent and nature of any litigation concerning the controversy already commenced by or against members of the class;” (3) “the desirability or undesirability of concentrating the litigation of the claims in the particular forum;” and (4) “the difficulties likely to be encountered in the management of a class action.”95
6. Expert Testimony
In Visa Check, the Circuit held that “a district court may not weigh conflicting expert evidence or engage in ‘statistical dueling’ of experts.”96 The Court’s role was merely to “ensure that the basis of the expert opinion is not so flawed that it would be inadmissible as a matter of law.”97 However, in Miles I, the Second Circuit disavowed that holding, explaining instead that “[a] district judge is to assess all of the relevant evidence admitted at the class certification stage and determine whether each Rule 23 requirement has been met, just as the judge would resolve a dispute about any other threshold prerequisite for continuing a lawsuit.” 98
C. Securities Fraud
To state a claim for securities fraud, a plaintiff must plead “both transaction causation (also known as reliance) and loss causa*93tion.”99 Transaction causation requires a plaintiff to demonstrate that ‘“but for the claimed misrepresentations or omissions, the plaintiff would not have entered into the detrimental securities transaction.’ ”100 Loss causation is “the proximate causal link between the alleged misconduct and the plaintiffs economic harm.”101 “To that end, the plaintiffs complaint must plead that the loss was foreseeable and caused by the materialization of the risk concealed by the fraudulent statement.”102
1. Transaction Causation
a. Omissions
The Supreme Court has held that a presumption of reliance may apply in eases in which plaintiffs have alleged that defendants failed to disclose information. In Affiliated Ute Citizens of the State of Utah v. United States, the Court held that where a plaintiffs fraud claims are based on omissions, transaction causation may be satisfied so long as the plaintiff shows that defendants had an obligation to disclose the information and the information withheld is material.103 Facts are material if “a reasonable investor might have considered them important in the making of [a] decision.”104
This presumption is nevertheless not conclusive.105 “Once the plaintiff establishes the materiality of the omission ... the burden shifts to the defendant to establish ... that the plaintiff did not rely on the omission in making the investment decision.”106 To satisfy this burden, a defendant must prove “that ‘even if the material facts had been disclosed, plaintiffs decision as to the transaction would not have been different from what it was.’ ”107
b. Misrepresentations
In Basic v. Levinson, the Supreme Court determined that an investor may also invoke a rebuttable presumption of reliance in cases of misrepresentations. The Court held that an investor may avail herself of the presumption that she “relied on the integrity of the price set by the market” if the market is efficient.108 The Court observed that “the market ... ideally, transmits information to the investor in the processed form of a market price. Thus the market is performing a substantial part of the valuation process ....”109 The Court noted that Congress expressly relied on the efficient capital markets hypothesis: “‘The idea of a free and open public market is built upon the theory that competing judgments of buyers and sellers as to the fair price of a security brings [sic] about a situation where the market price reflects as nearly as possible a just price.’ ”110 Thus, “[b]ecause most publicly available information is reflected in [the] market price, an investor’s reliance on any public material misrepresentations, therefore, may be presumed for purposes of a Rule 10b-5 action.”111
The Supreme Court thus permitted plaintiffs who demonstrate an efficient market to benefit from two presumptions: “(1) misrepresentations by an issuer affect the price of *94securities traded in the open market, and (2) investors rely on the market price of securities as an accurate measure of their intrinsic value.”112 Defendants can rebut such a presumption by demonstrating that the market price was not affected by the misrepresentations, possibly by showing that market makers knew the truth or that the concealed information “credibly entered the market and dissipated the effects of the misstatements ....”113
In dicta in Miles I, the Second Circuit suggested that the Basic presumption may not apply “to tie-in trading, underwriter compensation, and analysts’ reports.”114 The reasoning behind this statement is unclear. In an efficient market, prices reflect all available information, including the information presented by tie-in trading, underwriter compensation, and analyst reports. In the absence of a controlling holding from the Circuit, the Basic presumptions remain available where plaintiffs can demonstrate that the market is efficient.
2. Factors of an Efficient Market
There are two core requirements for an efficient market: “[l]arge numbers of rational and intelligent investors,” and “[i]mportant current information” that is “almost freely available to all participants....”115 Unfortunately, it is difficult to test for these requirements directly. Therefore, courts use a variety of factors to evaluate whether a market for securities is efficient.
In Cammer v. Bloom, the court enumerated five factors that are frequently used to determine whether a market is efficient.116 These factors are the average weekly trading volume; the number of analysts who follow the stock; the existence of market makers and arbitrageurs; the ability of the company to file SEC Form S-3;117 and evidence of a rapid share price response to unexpected news.
The court in Krogman v. Sterritt raised three additional factors. First, the court noted that investors tend to be more interested in companies with higher market capi-talizations, thus leading to more efficiency.118 Second, the court determined that a small bid-ask spread indicated that trading in the stock was inexpensive, suggesting efficiency.119 Third, the court looked to the percentage of shares that were available to the public. Because insiders are more likely to have private information, if substantial portions of shares are held by insiders, the price is less likely to reflect only the total of all public information.120
a. Average Weekly Trading Volume
As Cammer states, high volume suggests efficiency “because it implies significant investor interest in the company. Such interest, in turn, implies a likelihood that many investors are executing trades on the basis of newly available or disseminated corporate information.” 121 Cammer supposes that turnover of two percent or more of outstanding shares would justify a strong presumption of *95efficiency, while turnover of one percent would justify a substantial presumption.122
b. Number of Securities Analysts
Cammer recognizes that a stock covered by a “significant number of analysts” is more likely to be efficient because such coverage implies that investment professionals are following the company and making buy/sell recommendations to investors.123
c. Existence of Market Makers and Arbitrageurs
Cammer explains that “[t]he existence of market makers and arbitrageurs would ensure completion of the market mechanism; these individuals would react swiftly to company news and reported financial results by buying or selling stock and driving it to a changed price level.”124 But Krogman responded that the mere number of market makers, without more, is essentially meaningless; “what is important is ‘the volume of shares that they committed to trade, the volume of shares they actually traded, and the prices at which they did so.’ ”125 One study found that the number of market-makers is not correlated with the efficiency of the market.126 Nevertheless, this factor can provide reasonable guidance in determining whether the Basic presumptions apply.
d. Eligibility to File Form S-3
The SEC permits a company to file Form S-3 when, in the SEC’s judgment, the market for shares in the company is reasonably efficient at processing information.127 The Cammer court emphasized the SEC’s statement that the Form S-3 is “predicated on the Commission’s belief that the market operates efficiently for these companies [that file Form S-3s], i.e., that the disclosure in Exchange Act reports and other communications by the registrant, such as press releases, has already been disseminated and accounted for by the market place.”128 Because of the SEC’s expertise in this area, I agree that this factor provides a strong indication of efficiency.
e. Other Factors
Empirical evidence of rapid price changes in response to unexpected information is highly probative of efficiency because it demonstrates that the market was likely to have incorporated the information in question into the share price.129 However, there is no consensus as to how quickly share prices must change to justify a finding of efficiency.
Similarly, the markets for companies with higher market capitalizations and shares with a smaller bid-ask spread are more likely to be efficient.130 Finally, the percentage of shares available to the public generally bears a direct relationship to efficiency.131
D. Class Notice and Fairness Hearing
In addition to reviewing the proposed terms of settlement and making a preliminary determination on the fairness, *96reasonableness and adequacy of the settlement terms,132 the court must also direct the preparation of notice of the certification of the settlement class, the proposed settlement, and the date of the final fairness hearing.133 The Private Securities Litigation Reform Act (“PSLRA”) requires that notice to the class include each of the following statements and a brief summary of each in a cover page: (1) statement of plaintiff recovery; (2) statement of potential outcome of the ease; (3) statement of attorneys’ fees and costs sought; (4) identification of lawyers’ representatives; (5) reasons for settlement; and (6) any other information required by the Court.134 “There are no rigid rules to determine whether a settlement notice to the class satisfies constitutional or Rule 23(e) requirements; the settlement notice must fairly apprise the prospective members of the class of the terms of the proposed settlement and of the options that are open to them in connection with the proceedings.”135
The class notice should also inform potential class members of the date of the “fairness hearing.” At the fairness hearing, class members (and nonsettling defendants whose rights may be affected by the proposed settlement) have the opportunity to present their views of the proposed settlement, and the parties may present arguments and evidence for and against the terms. The court then makes a final determination as to whether the proposed settlement is “fair, reasonable and adequate.”136
IV. DISCUSSION
A. Class Certification for Settlement Purposes
1. The Rule 23(a) Requirements
Several of the findings I made in the 2004 Class Certification Opinion require only brief reexamination. I observed in that Opinion that “[t]he common issues of liability presented in these six class actions are overwhelming.” 137 Although that decision was made in the context of the “some showing” standard, after reviewing the evidence I have no trouble concluding that the commonality requirement is satisfied under the heightened standard that now applies. The requirement of numerosity is also clearly satisfied.138
Similarly, I observed in the 2004 Class Certification Opinion that the class representatives “allege that they were harmed in the same unitary scheme as the rest of the class.”139 I rejected defendants’ argument that these representatives were subject to atypical defenses.140 Again, I conclude that the facts here justify a finding of typicality under the applicable standard.
Defendants had also argued that certain class representatives were inadequate. In the 2004 Class Certification Opinion, I found that defendants’ arguments were unavailing.141 After careful review, I again conclude that these representatives are adequate.
2. Rule 23(b) Requirement of Predominance
Rule 23(b)(3) requires that common issues of fact “predominate over any questions af*97fecting only individual members. Miles I, the Second Circuit vacated this Court’s certification of the classes, concluding that the predominance requirement was not met.143 The court held that “the market for IPO shares is not efficient” and that plaintiffs had themselves alleged that there was an “industry-wide understanding that those who agreed to purchase in the aftermarket received allocations.”144 As a result, the court ruled that the Basic presumption could not apply to satisfy the reliance element, and evidence of knowledge would negate the inference that all of the investors had relied on the inflated prices to their detriment. Individual issues would therefore predominate.145 The court also opined that ascertainment of which putative class members have “paid any undisclosed compensation to the allocation underwriters” was an aspect of the litigation that was “bristling with individual questions.” 146 As a result, I must now reexamine the predominance requirement with respect to reliance, knowledge, and aseertainability in light of the amended class definition. I also evaluate the predominance requirement with respect to loss causation in more detail. ”142 In
a. Reliance
Demonstrating reliance is frequently a difficult hurdle in certifying a class of plaintiffs in a securities action. To recover, each plaintiff must demonstrate that she relied to her detriment on defendants’ false statements and market manipulation. Instead of demonstrating individual reliance, plaintiffs seek to rely on the Basic and Affiliated Ute presumptions of reliance.147
i. The Basic Presumption
Plaintiffs contend that the markets for the 309 cases were “efficient” during the relevant periods meaning that they conformed to some degree to the efficient capital markets hypothesis.148 In support of this claim, plaintiffs proffer the expert reports of Professor Daniel R. Fischel which were submitted during plaintiffs’ 2004 and 2007 motions for class certification.149 Professor Fischel is the Lee and Breña Freeman Professor of Law and Business at the University of Chicago Law School and Chairman and President of Lexecon Inc., an economic and consulting firm.150 Although Professor Fischel’s reports address only the markets of the six stocks which were the focus of the *982004 and 2007 motions,151 he has since submitted an affidavit opining that his findings in 2004 and 2007 with respect to the efficiency of the markets of the six focus cases are equally applicable to the 303 non-focus cases at issue.152
Defendants had collectively submitted numerous expert reports to contest the efficiency of the markets of the six focus cases in 2004 and 2007.153 However, they have since informed the Court that — for purposes of settlement class certification only — they are not challenging the efficiency of the markets in any of these cases.154 Indeed, by stipulating to certify the classes, they have effectively conceded that the markets were efficient enough for plaintiffs to rely on the Basic presumption. Nevertheless, I will briefly address each of the factors courts consider when evaluating market efficiency. In doing so I will address some of the criticisms made by defendant’s experts of Fischel’s analysis.
Trading Volume
Fischel found that the weekly trading volume of each of the focus case stocks averaged significantly above the two-percent threshold. His findings are summarized in the following table:155

Fischel also analyzed the trading volume with respect to each of the other 303 litigated stocks.156 He found that 301 of them had average weekly turnover of at least one percent, indicating a substantial presumption of market efficiency, and 290 had average weekly turnover of at least two percent, justifying a strong presumption of efficiency.157 Thus, the trading volume for all litigated stocks suggest that the markets for these stocks were efficient.
However, as discussed, extraordinarily high volume may be indicative not of an efficient market but rather of a market having difficulty valuing a stock. Fischel’s statistics for first-day trading of the focus stocks indicate exactly this sort of valuation problem. None of these statistics support a finding of efficiency on the first day of trading, though the evidence in support of a finding of efficiency is strongest as to Corvis. The trading volume presents strong evidence of market efficiency during the entire class period, except the first days, for Engage, FirePond, Sycamore, and VA Linux, and during the first day only for Corvis.
Coverage by Investment Analysts
Fischel has provided the Court with statistics on mass media coverage of the focus case stocks. However, there is no basis for concluding that non-specialized media coverage is correlated with market efficiency. I therefore disregard statistics that refer to general media and look only to securities analyst coverage.
Fischel also provided the Court with the number of reports issued during the quiet period of each focus case stock that, though focusing on other companies, mention the relevant focus case stock. Generally, these mentions are in passing and do not disclose new and useful information.158 Further, these mentions do not imply that investment professionals are following the company and making buy/sell recommendations to investors. Therefore, I am disregarding reports during the quiet period that merely mention the focus case stocks without providing new, useful information to investors.
Fischel also found that the focus case stocks were “covered extensively by investment professionals ....”159 His findings are summarized in the following table:160
[[Image here]]
*100The chart shows that there was significant and extensive coverage of these stocks by investment professionals during the class .period. Fischel similarly determined that the 303 other litigated stocks were the subjects of analyst reports during their respective class periods and that “[mjany of the 303 stocks at issue were followed by numerous analysts.”161
However, the level of analyst coverage during the quiet period with respect to the focus cases was much smaller than after the conclusion of that period. At best, this factor may weigh in favor of efficiency during the quiet period for Corvis but not for the other stocks. While the Court has not been provided specific data with respect to analyst reports for the other 303 litigated stocks, the data will most likely show that there were fewer analyst reports during the quiet periods.
Presence of Market Makers
Fischel determined that there were substantial numbers of market makers in each of the focus cases. His findings regarding the number of market makers are presented in the following table:162
[[Image here]]
Fischel also analyzed the number of market makers with respect to the 303 other litigated stocks. He found that of the 303 stocks at issue, 296 stocks were listed on the NASDAQ at their initial listing, and each of these stocks had at least 14 market makers at the time of its IPO and on December 6, 2000 or its last day of trading, more than the eleven market makers the Cammer court found to be sufficient to support a finding of an efficient market.163 Fischel notes that the remaining seven stocks were traded on the NYSE or the American Stock Exchange, and that courts have held that trading on these exchanges provides the necessary evidence to satisfy this factor.164 The number of market makers in the litigated stocks is therefore indicative of efficiency.
Presence of Arbitrageurs
Fischel concluded that there was substantial short interest in each of the focus case stocks, which was indicative of efficiency.165 However, the evidence demonstrates that there were significant obstacles to arbitrage at the outset of trading of each of the focus case stocks.166 Although Fischel does not *101provide specific data with respect to the short interest in each of the 303 litigated stocks, it is reasonable to conclude that the evidence will be similar to the focus case stocks. Therefore, this factor weighs against a finding of efficiency during the first weeks of trading.
Eligibility to File an S-3 Registration Statement
Fischel notes that at the time of the IPOs of the focus case stocks, “regulations required that a company have reported under the 1934 Act for one year or more in order to file [a] Form S-3.”167 Because none of the focus ease stocks had reported under the Exchange Act for one year or more, they were ineligible to file a Form S-3 at the time of their IPOs.168 In Cammer, the court noted that if a company was not eligible to file a Form S-3, this factor will not necessarily weigh against a finding of market efficiency if “such ineligibility was only because of timing factors rather than because the minimum stock requirements set forth in the instructions to Form S-3 were not met.”169 Fischel found that for five of the six focus case stocks, the market values of their public “floats” during their class periods were at least $75 million, which is the size of the float required by the SEC at that time to be eligible to file a Form S-3.170 In the case of iXL, the float exceeded $75 million until November 2000, when it dropped below that value.171 Fischel does not opine with respect to the rest of the 303 litigated stocks.172 Because there is no evidence with respect to the 303 other litigated cases, and in any case, the ineligibility of a company to file Form S-3 because of timing requirements does not necessarily indicate inefficiency, I find that this factor does not weigh for or against market efficiency.173
Incorporation of Information into Share Price
Fischel has observed that “the more rapidly prices reflect publicly available information, the more sensible it is to apply” the efficient capital markets hypothesis.174 Using event study methodology, Fischel determined that the focus case shares tended to react significantly to unexpected corporate events. For each focus case, Fischel listed examples where unexpected information was released to the public and the share price moved in a statistically significant manner.175 Fischel also analyzed stock price reactions to news for the 303 other litigated stocks and found that stock prices “reacted quickly” to new and publicly available information.176
Defendants’ experts submitted a number of challenges to Fischel’s findings. First, they argued that because Fischel analyzed share price movements on a daily basis, he *102obscured the fact that some of the share price movements occurred hours after the disclosure of new information.177 For instance, defendants’ expert Gompers specifically observed that Fischel attributes the increase in Sycamore’s stock price on January 21, 2000 to a morning announcement that Sycamore planned to use technology from ION Networks in its products. Although this announcement was made in the morning, much of Sycamore’s stock price adjustment occurred in the afternoon.178 Gompers concludes that this delay is evidence against a finding that the market for Sycamore shares was efficient.179
In response, Fischel noted that academic research indicated that the adjustment to share prices following an announcement “lasts anywhere from one to seventeen hours after a news release....”180 Indeed, evidence that share prices effectively incorporate new information within hours of the announcement of that information indicates efficiency, not inefficiency. While in a perfectly efficient market share prices would adjust instantaneously, the Basic presumption does not require a perfectly efficient market, only a market efficient enough to incorporate information into the share price with reasonable speed.
Second, Gompers-after examining the twenty-eight days identified by Fischel as having a statistically significant price change for Sycamore-concluded that the price moved without the release of relevant new information on twenty-two of those days.181 Fischel responded that a conclusion of inefficiency does not follow merely because significant share price changes are not always explained by known announcements.182 He argued that “most of the daily variation in stock prices generally is unexplained by market factors, industry factors, or firm-specific news.”183 He also noted that prices can change when investors trade on private information, and that it is not always possible to identify the relevant information that moved share prices years after the fact.184
Third, Gompers critiques Fischel’s application of this methodology to Sycamore. He notes that “[fjinding a few examples of rapid reaction to information does not demonstrate that the market always responds fully and rapidly to public information throughout the purported Class Period.”185 However, as with the other factors, there is no claim that this factor conclusively proves efficiency. A conclusion as to efficiency is made after all of the factors are examined. Fischel’s study demonstrates a correlation between the studied factors and the requisite degree of efficiency.
Notwithstanding defendants’ experts’ criticisms, Fischel’s study indicates that the prices of focus case stocks were generally responsive to the release of information throughout the class period. However defendants’ experts rightfully observe that this study tells little about the efficiency of the stocks during the quiet period.186
Other Factors
Fischel determined that the market capi-talizations of the focus case shares were above the median NASDAQ National Market *103capitalization on the first day of trading, at the end of each stock’s quiet period, and at the end of the class period.187 He found the same to be true of all but one of the other 303 litigated stocks.188
In addition, Fischel determined that the bid-ask spreads of the focus case shares throughout the proposed class period were less than the median bid-ask spread of all NASDAQ National Market shares, at least for portions of their trading histories.189 Fis-chel further found that this was also true for 274 of the 294 stocks at issue that traded on the NASDAQ during their entire class periods.190 He noted that the remaining twenty stocks had bid-ask spreads between the median and seventy-fifth percentile of all NASDAQ stocks.191
Fischel also noted that only a small percentage of the issuers’ shares were held by the public at the time of their IPOs, but concluded that because those shares had sufficient value, there were “substantial incentives for public shareholders to acquire and act on information ...,”192 Therefore, these factors also point to the efficiency of the markets in all of the litigated eases.
General Criticisms
Defendants’ experts also made a number of general challenges against plaintiffs’ showing of efficiency. I will briefly address some of them.
Widespread Knowledge
Some market participants who knew of the alleged scheme could be expected to act on the basis of that knowledge.193 If such knowledge were sufficiently widespread, the manipulation would fail because market participants would bid the shares to their fundamental value. This is called the “truth-on-the-market” defense. Under this corollary of the fraud on the market theory, “if the information is already known to the market, [] the misrepresentation cannot then defraud the market.”194 Indeed, several experts opined that in an efficient market, the alleged artificial inflation would not persist for the period alleged by plaintiffs.195
However, plaintiffs have revised their Master Allegations to allege that the scheme was not well-known.196 Where information about the full extent of the scheme is not public, even in a perfectly efficient market artificial inflation could persist for a long period. This is especially true where those with private knowledge of the manipulation do not trade on that knowledge. For example, if allocants knew of certain underwriters’ intention to boost share prices and participated to earn the underwriters’ goodwill, it is unlikely that those allocants would then trade on that knowledge given that such trades would depress those share prices, frustrating the pur*104pose of the underwriters and depleting that goodwill. Thus, if anything, sustained inflation in efficient markets would seem to suggest that the scheme was not widely known.
Inefficiency as a Result of Stabilization Activities
In addition to criticizing Fischel’s analysis, several of defendants’ experts presented affirmative evidence that the market for the focus case shares was inefficient. Stulz observed that underwriters were permitted to support the price of shares for some time after the IPO.197 This may prevent share prices from reflecting all adverse information, and “[t]he possibility of stabilization activities has a pervasive effect on the trading of investors since they know that such activities can limit their losses.”198 When underwriters do take steps to stabilize share prices, they generally do so only for the first few days or weeks after trading begins.199 While this factor indicates that prices during the first days or weeks of trading may not be efficient, it has little bearing on prices after that period.
Deviation of Market Valuation from Fundamental Valuation
Gompers used discounted cash-flow analysis (“DCFA”) to demonstrate that the market for Sycamore shares was inefficient. DCFA involves determining the future value of all of a company’s expected income and expenditure streams, and then discounting those streams to their present value. The sum of all of these discounted cash flows is considered the fundamental value of a company.200 Gompers argues that the deviation of the market valuation of Sycamore from its fundamental valuation indicates an inefficient market.201 He contends that a company’s misleading positive statements about its business prospects or the manipulation of prices by engaging in trading would cause analysts to increase estimates of growth, which would also increase future cash flow calculations and fundamental value.202 Using DCFA, Gompers also determined that “irrational investor sentiment was widespread” among companies in Sycamore’s industry, suggesting that this market was generally inefficient during the proposed class period.203
Fischel responds that Gompers has failed to account for “uncertainty about the average growth rates of technology firms at the time.” 204 He further notes that academic research has found that when this uncertainty is incorporated into some models, the valuation appears reasonable.205
In addition, while a positive news announcement regarding business prospects may be worthy of a revision of earnings estimates, unexplained increases in demand would not require such a revision. Thus, where prices have been directly manipulated, a deviation of the market valuation from the fundamental valuation would not be surprising. Such observation indicates only that the market for the stock is inflated, not that the market is inefficient.
The Internet Bubble
Barry observes that finance scholars widely recognize that there was market inefficiency in technology stocks from 1998 to 2000.206 However, academics are not in agreement that there was a bubble. One source observes:
The extraordinary rise in Internet values ... has generally been called the ‘Internet bubble’. The fact that prices fell in March *105of that year, and continued to fall throughout 2000, gave some credibility to this designation. However, one cannot infer necessarily from this ex-post realization that market values did not in fact reflect fundamental values about cash flows. Tautologically, changing expectations about cash flows or discount rates, coupled with realization of various Internet fundamentals, could also explain the rise and drop in prices. We, as well as anyone else, will not be able to answer this question definitively here.207
Another paper cited by defendants observes that while stock market crashes are often cited as evidence against rational share price models, behavioral theory (which incorporates investor irrationality) “has not really made much progress in understanding crashes____” 208 Based on the available evidence, defendants have failed to demonstrate that the overall market conditions preclude the application of the Basic presumptions during the relevant period.
Conclusion
Having reviewed the evidence, I conclude that plaintiffs have proven by the preponderance of the evidence that the markets for the litigated stocks were sufficiently efficient to justify the Basic presumptions during the proposed class periods. Plaintiffs have shown that the share prices are likely to have reflected public information, and that reasonable purchasers would be justified in relying on those prices.
However, there is insufficient evidence of efficiency to permit the use of the Basic presumption with respect to trading during the quiet periods. To the contrary, the evidence indicates that the quiet periods were marked by chaotic pricing, irrational purchases, and market inefficiencies.209 Fis-chel’s own evidence demonstrates that the markets for the focus case shares were inefficient during the first weeks of trading. A purchaser of these securities during the relevant quiet period could not reasonably rely on the market price to reflect the market’s judgment of the security’s value. Therefore, the Basic presumptions cannot apply to these periods.
ii. The Affiliated Ute Presumption
Nevertheless, plaintiffs’ claims concern defendants’ failure to disclose the manipulative scheme. Plaintiffs allege that defendants’ principal misconduct related to their omissions with respect to the existence of the tie-in agreements and the undisclosed compensation.210 Therefore, plaintiffs are also entitled alternatively to the Affiliated Ute presumption, which provides that “reliance is presumed when the claim rests on the omission of a material fact.”211 In the 2004 Class Certification Opinion, I found that the Affiliated Ute presumption applied “to the extent [plaintiffs’] 10b-5 claims derive from material omissions.”212 There is no reason for me to *106revisit this holding.213 Therefore, plaintiffs have demonstrated that common issues will predominate with respect to reliance during the class periods of all stocks, and the classes may include plaintiffs who purchased during the quiet periods.
b. Loss Causation
In addition to transaction causation, plaintiffs must demonstrate that common questions predominate over individual inquiries with respect to loss causation. By stipulating to class certification, defendants have conceded that individual issues do not predominate with respect to loss causation. Nevertheless, the Court has a duty to make its own evaluation of this assertion. If plaintiffs have failed to demonstrate that they can show class-wide loss causation, no class can be certified.
To demonstrate loss causation, plaintiffs must show a causal connection between the alleged wrongdoing and their losses. Plaintiffs seek to rely on the expert reports of Professor Fischel, who seeks to prove loss causation by demonstrating first, that defendants’ scheme inflated the prices of the securities;214 and second, that the inflation dissipated over the course of the class period. The 2004 Class Certification Opinion held that Fischel’s theory was “not fatally flawed.”215 I now reexamine Fischel’s theory under the heightened standard that applies. In doing so, I address additional challenges that defendants’ experts made to Fischel’s theory when they submitted reports in response to plaintiffs’ 2007 class certification motion.
i. Fischel’s Methodology
I discussed Fisehel’s methodology for demonstrating loss causation in detail in the 2004 Class Certification Opinion.216 I therefore summarize it briefly here. In Fischel’s first analysis, he demonstrates how tie-in agreements increased the demand for and prices of the stocks in the pre-open bid sessions and in the aftermarket.217
Fischel’s second analysis seeks to demonstrate the causal link between the tie-in agreements and continued inflation in the stock prices.218 He proposes the use of either of two theories: the Comparable Index Approach, which “approximates what the returns on the security would have been had the fraud not occurred” and the Event Study Procedure, which “treats the fraud-related disclosures as events and substitutes the predicted return on event days.”219 Under both approaches, a value line would be constructed, which substitutes returns had the fraud not occurred.220 The difference between the *107value line and the price line would be the measure of artificial inflation.221 Fischel claims that these models can be used to analyze artificial inflation, loss causation, and damages.222
Each of the focus case stocks eventually plummeted to a value close to zero.223 As I noted in the 2004 Class Certification Opinion, once artificial inflation is proven to have occurred, “[s]ome loss causation may be inferred simply from the disappearance of the original inflation.” 224 Indeed, there can be little argument that near-worthless shares are no longer inflated.
However, the simple fact that prices fell between two points in time is not loss causation. In Dura Pharmaceuticals, Inc. v. Broudo, the Supreme Court explained that at the moment of inflation — “as a matter of pure logic ... the plaintiff has suffered no loss; the inflated purchase payment is offset by ownership of a share that at that instant possesses equivalent value.” 225 Value here means market value, not fundamental value. I now consider additional evidence of loss causation from Fischel and criticisms from defendants’ experts to determine whether plaintiffs have demonstrated by a preponderance of the evidence that Fischel’s theory can be used to prove loss causation on a class-wide basis.
ii. Additional Evidence of Initial Inflation
First-Day Returns
In addition to previously showing that the stocks in this litigation experienced unusually high first-day returns compared to IPOs from 1980 through 1997 and IPOs that are not included in this litigation, Fischel also shows that the returns are high compared to *108IPOs during the period of 2001 to 2006.226 He notes that “the average first-day return for IPOs was 10.8 percent, 95 percent of all IPOs had first-day returns less than 44 percent, and 99 percent of all IPOs had first-day returns less than 69 percent.” 227 This is compared to the smallest first-day return of the six focus stocks of 49 percent and the rest of the focus stocks which had returns exceeding 135 percent.228 This is strong evidence that the returns of the IPOs in this litigation were the product of inflation.
Pre-Opening Quotations
As noted, Fischel hypothesizes that much of the initial inflation was accomplished through the setting of a quote by the lead underwriters during the pre-opening bid session. Fischel notes that the pre-opening bid quote exceeded the offering price for five of the six focus case stocks by 66.67 percent or more.229 This compares to less than 2.5 percent of IPOs prior to the class period.230 He also notes that the pre-opening bid alone accounts for as much as 81.2 percent of the overall first-day return for the focus case stocks.231 This indicates that the prices of IPO stocks were heavily influenced by lead underwriters’ pre-opening quotes.
A number of defendants’ experts criticized Fischel’s conclusions, attempting to show that there was no link between a lead underwriter’s quote and price inflation in the focus stocks.232 In response, Fischel performed a regression analysis to test the relationships between IPO initial returns, the first bid in the pre-opening by any market maker, the lead underwriter’s first bid, and the offer price revision.233 He found that there was a “powerful, statistically significant relationship between the initial return and both the lead underwriter’s first bid and the offer price revision ____”234 The regression also demonstrated that there was no significant relationship between the initial returns and first bids that are not made by the lead underwriter.235
In addition, Fischel showed that for three of the focus case stocks — in which first bids were entered by market makers other than the lead underwriter — the lead underwriter’s first bids were substantially higher than these bids, and subsequent bids followed the lead underwriter’s first bid.236 For instance, during the pre-open market for FirePond, Ramius Securities, LLC entered bids of $20 and $25.237 After Robertson Stephens, the lead underwriter, issued its first bid at $49, the next bidder, Herzog, Heine, Geduld, Inc., put in bids for $40, substantially greater than the first bids from Ramius Securities.238 The evidence follows a similar pattern for Sycamore and VA Linux.239
iii. Additional Evidence of Sustained Inflation
Analyst Reports
In support of his theory that prices remained inflated throughout the class period, Fischel examined the effects of analyst reports on share prices. He observed that analyst price targets “always exceeded the inflated stock prices at the time the price *109target was issued, and ... the price targets were often far above the inflated stock prices.” 240 Noting that it has been widely established that analyst reports can significantly affect stock prices, he concluded that had those analysts released objective, honest reports, those reports would have led to a substantial decrease in share prices.241 Thus, while the analyst reports themselves did not directly cause any inflation, they sustained the artificial inflation by not disclosing the truth.
Pending Limit Orders to Buy
In addition, Fischel analyzed pending limit orders to purchase stock placed by allocants with alleged tie-in agreements, noting that such pending orders would have supported the prices of the focus case stocks after trading commenced.242 He concluded that at all relevant times there were pending limit orders for eight percent or more of the shares offered 243 He also found that for four of the six focus stocks, more than 90 percent of these pending limit orders were at prices that exceeded the respective stock’s offer price by 50 percent or more.244 For one of the focus case stocks, more than 80 percent of the limit orders were at prices that exceeded the offer price by 50 percent or more.245 Although pending limit orders for iXL stock were smaller, the data also showed that the prices for these orders exceeded its offer price.246
Support from Financial Literature
Finally, two scholarly articles cited by Fis-chel support the hypothesis that laddering can cause long-term price effects. The first, by Rajesh Aggarwal et al., constructs a model in which tie-in purchases occur in the first day or days of public trading, and allocants sell those purchases “fairly quickly” but “certainly ... prior to the expiration of the lockup period for insiders, usually six months post-IPO.” 247 Indeed, they observe that prices for allegedly manipulated IPOs rise for five months and then fall.248 Their research indicates that those IPOs outperform non-implicated IPOs for the first week, match their performance until the sixth month, and then underperform for three years.249
In the Aggarwal model, some traders are “momentum investors”' — “arbitrageurs, day-traders, sentiment investors, or information seekers” who purchase if they can infer from prices and volumes that an informed investor is purchasing the stock 250 These momentum investors are otherwise rational. It is momentum from these investors that sustains the artificially high price for some period after the alleged manipulation.251
The second work is a paper by Qing Hao in which she concludes that while laddering can exist without “information momentum,” the “benefits of laddering for underwriters are greater when market prices are affected *110by information momentum.” 252 Information momentum exists where high initial prices “induce more information production and additional demand,” spurring prices yet higher.253 Hao also concludes that laddering results in “long-run underperformance and a negative correlation between short-run and long-run returns.” 254 Hao hypothesizes that “momentum is a major factor that fed laddering during the late 1990s and early 2000.”255
iv. Criticisms
Inflation Inconsistent with Efficient Market
Defendants’ expert Pfleiderer observes that because any inflation in share prices due to laddering would be caused by market participants believing that the ladderers have confidential positive information, share prices would fall when the ladderers sold their shares.256 Similarly, O’Hara argues that in an efficient market, “the information effect of any given trade ... when it has an effect at all, is short-lived — typically measured in seconds or minutes, and certainly not in the months and years alleged.”257
However, whether a trade affects prices will depend on whether the market perceives the market participant to possess information. Therefore, Fischel explains that “the effect of aftermarket sales need not offset the effect of aftermarket purchases since other market participants may, as defendants’ experts themselves recognize, perceive the purchase as informed, but the sale as uninformed.” 258 In addition, other market participants may “mimic” the buying behavior of initial allocants because they believe that al-locants may have information about the value of the stock that they do not possess.259
In addition, defendants’ other tactics may have also contributed to the sustained inflation even in an efficient market. For instance, analyst reports that continued to tout the quality of the stocks could have fooled the market into thinking that the stocks still had substantial fundamental value.
Corrective Disclosures
Defendants’ experts argue that no significant price movements followed corrective disclosures for any of the stocks during the period, thereby illustrating that the prices of the stocks were not inflated.260 Fischel counters this observation, explaining that each of the focus stocks declined significantly after adverse news was publicized.261 In addition, Fischel notes that defendants’ experts fail to *111recognize that “when there is laddering, an absence of favorable news can be a form of disclosure.” 262 For instance, investors may expect imminent financial news to support the price of the stock, and when no such positive news surfaces, prices decline.263
Share Price Mirroring Market Conditions
Defendants’ expert Cornell observes that if plaintiffs’ allegations are accurate, the behavior of the share price of each focus case should be correlated with the behavior of each other focus case in “IPO time” — that is, time since the IPO. Cornell reasons that because all five were allegedly subject to similar laddering schemes, the effects of those schemes would appear at roughly the same period after the IPOs.264 Cornell found that there were in fact negative correlations when compared in this way — however, when compared in absolute time (that is, prices on each day regardless of the date of the IPO), there was a strong positive correlation. Cornell interprets this to mean that the dramatic changes in the prices of the focus case shares was caused by general market conditions, not laddering.265 However, plaintiffs allege that the general changes in the market resulted from the actions of defendants, as inflation in hundreds of IPOs dissipated. It is not surprising that general market conditions would have substantial effects on IPO prices.
Controlling for Other Factors
Defendants’ experts criticize Fischel’s model for failing to take into account factors other than market conditions that might influence stock prices, such as unrelated business developments.266 They note that in the ease of their focus stock, there were instances of price inflation that could not have been attributable to defendants’ conduct.267
However, Fischel responds that he does not support an approach that merely compares the stock price to an index mechanically without any consideration for the special *112circumstances of each stock.268 For instance, he proposes capping the amount of inflation by the amount of artificial inflation at the IPO date, noting that it would be unreasonable to expect inflation to exceed what it was at the time of the IPO.269 He also notes that if the Court finds that increases in the stock prices occurred in response to “non-fraud related factors,” these increases would simply be taken out and the inflation held constant.270 Any other anomalies can be eliminated by adjusting the results to conform with the evidence.271 These adjustments would be made on a class-wide basis.272
A Trade-by-Trade Analysis
Several of defendants’ experts suggested that artificial inflation be measured on a trade-by-trade basis.273 In response, Fischel argued that trade-by-trade analysis is inappropriate because plaintiffs are not just alleging the existence of tie-in agreements but also that defendants failed to disclose that they were receiving kickbacks and that they were using their research analysts to prop up prices.274 In addition, the trade-by-trade analysis would not correctly measure the effects of trades that were made to satisfy obligations of the tie-in agreements. This is because trades may affect prices before they are executed — as underwriters become aware of impending demand — and after trades are executed — as a result of “positive feedback trading” or “speculative excess.”275
The Case of iXL
Several of defendants’ experts disagree with Fischel’s conclusion that iXL’s price post-IPO was artificially inflated. They note that iXL’s first-day return was 49%, which is toward the lower end of the range of both the litigated and non-litigated sample.276 They also note that Merrill Lynch, the lead underwriter in iXL’s IPO placed a bid of $12.50 in the pre-open period, which was only $0.50 higher than the offering price of $12.00 and held the best bid for less than two minutes of the thirty-minute period.277 Thereafter, a number of other market makers entered to set new and higher bids, but Merrill Lynch never revised its bid so as to set a higher bid.278 They conclude that the increase in price during the pre-open period was driven by demand by retail investors, rather than by allocants with tie-in agreements.279 With respect to after-market trading, defendants’ expert Pfleiderer notes that “alleged tie-in allocants were net sellers in iXL on the first day and during the first ten days of trading.” 280 He opines that if buying by alleged tie-in allocants increased prices, *113then selling by the same entities would have brought prices down.281
Fischel conceded that the evidence with respect to laddering in the iXL IPO appears to be weaker than that of the other five focus stocks.282 Nevertheless, Fischel demonstrated that a lead underwriter’s bid can serve as a strong signal to market makers that enter bids thereafter. Thus, even though Merrill Lynch may have opened bidding at $12.50, that this bid price was above the offering price may still have contributed to inflationary bidding in the preopening period.283 In addition, although iXL’s first-day return was the smallest of the six focus cases at 49 percent, this return puts the stock in the top five percent of all IPOs from 2001 to 2006.284 Finally, although the pending limit orders were smaller for iXL than the other focus stocks, all of the pending limit order prices still exceeded iXL’s offering price.285 And most importantly, iXL’s stock price diminished to virtually zero at the end of its class period on December 6, 2000.286
Although the inquiry as to whether alleged laddering of the iXL stock led to inflationary pricing is far from clear, plaintiffs need not definitively show loss causation at the class certification juncture. This is a merit s issue that need not be definitively determined at this stage. The only question here is whether plaintiffs have demonstrated — by a preponderance of the evidence — that loss causation can be proven class-wide for iXL using Fischel’s methodology. They have succeeded in doing so.
Conclusion
Although defendants have raised a number of serious challenges to Fischel’s methodology, none of them tip the balance in defendants’ favor. Plaintiffs have demonstrated by a preponderance of the evidence that loss causation can be proven on a class-wide basis by showing that inflation existed at the time of the IPO and by demonstrating that inflation slowly dissipated throughout the class periods of each litigated stock.
c. Knowledge
In Miles I, the Second Circuit held that common questions do not predominate because “[t]he claim that lack of knowledge is common to the class is thoroughly undermined by the Plaintiffs’ own allegations as to how widespread was knowledge of the alleged scheme.” 287 While the 2004 Class Certification Opinion excluded from the proposed class “those investors who exhibit the hallmarks of full participation in the alleged scheme,” 288 the Circuit took issue with the inclusion of “those who participated in part and those who were required to remain ‘ready’ to purchase in the aftermarket if the underwriters so desired, all of whom knew of the alleged scheme.” 289 Finally, the Circuit observed that even were these parties excluded, plaintiffs had alleged that “the community of market participants and watchers” had knowledge of the scheme.290
Plaintiffs’ initial complaints and Master Allegations failed to convey that they were not alleging widespread knowledge. The Amended Complaints and Amended Master *114Allegations now allege that aftermarket investors “knew nothing about the scheme,” nor did “the overwhelming majority of retail alloeants----”291
Widespread knowledge of the alleged scheme is relevant in two ways. First, plaintiffs must explain how the manipulation succeeded if the market were efficient and a large number of market participants knew of defendants’ alleged activities. I addressed this issue in my discussion of market efficiency. Second, an individual class member cannot be said to have relied on defendants’ misrepresentations if he knew that they were false. Thus, if there is a significant question as to whether a substantial proportion of class members knew of the scheme, this individualized inquiry would predominate over common questions of law or fact and no class could be certified.
i. Alloeants
The original classes I certified excluded investors who “exhibit[ed] the hallmarks of full participation in the alleged scheme.”292 In Miles I, the Second Circuit noted that
that exclusion leaves within the class those who participated in part and those who were required to remain ‘ready’ to purchase in the aftermarket if the underwriters so desired, all of whom knew of the alleged scheme. Moreover, the exclusion of full participants from the class does nothing to lessen the broad extent of knowledge of the scheme throughout the community of market participants and watchers, and it is this widespread knowledge that would precipitate individual inquiries as to the knowledge of each member of the class, even as redefined.293
The Circuit thus questioned whether an allocant who knew of a plan to inflate the price of the shares that she had been allocated can be inferred to have had knowledge of the scheme to inflate the price of shares in other IPOs. Plaintiffs have remedied this problem by excluding all alloeants, except natural persons, who are recipients of shares from the “institutional pot” in any of the 309 stocks at issue in this litigation.294 In addition, any person that is or was previously named a defendant; any attorneys who have appeared in the actions on behalf of a named defendant; any members of the immediate family of any named defendant; any entity in which an excluded allocant or named defendant was a majority owner; any legal representatives, heirs, successors or assigns of any excluded allocant or named defendant; and any director, officer, employee, or beneficial owner of any excluded allocant or named defendant during any of the class periods is also excluded from the class definition.295 The parties have therefore ensured that all persons who can be expected to have learned about the alleged scheme are not permitted to participate in the settlement.296
ii. Non-Allocant Investors
As for those investors who did not receive any allocations in any IPOs, there is insufficient evidence to conclude at this time that there was widespread knowledge of the alleged scheme among them. Fischel analyzed *115media coverage during the proposed class periods and concluded that it did not indicate that there was widespread knowledge of the alleged scheme.297 First, he observed that these reports do not disclose specific details about the scheme, including which companies are involved (none of the focus cases are mentioned), the number of allocants that had tie-in agreements, or the details of these agreements.298 Second, he determined that of the quarter of a million articles published in the relevant period that include the term “initial public offering” or “IPO,” only seven articles mentioned tie-in agreements.299 Finally, he found that the focus case stocks continued to underperform key indices after the publication of these reports, which indicates that the reports did not resolve the artificial inflation.300 If the reports had caused the complete dissipation of the inflation in the stock prices, the prices would have dropped immediately and the stocks would have begun to trade in line with the market, but they did not. Fischel has therefore demonstrated that while there were a few scattered discussions throughout the media of the allegations during the relevant periods, they were insufficient to put non-allocant investors on notice as to the manipulations in any of the focus cases. The same could be concluded with respect to the other litigated stock.
Plaintiffs have thus shown by a preponderance of the evidence that when the classes are properly circumscribed and institutional allocants are excluded, individual questions of knowledge will not predominate over common ones.
d. Ascertainability
Ascertainability is a prerequisite for class certification. In Miles I, the Circuit found that the determination of membership in the class was “bristling with individual questions ....”301 Clearly investors who paid undisclosed compensation to the underwriters would be excluded from the class. But determining whether various types of compensation paid by plaintiffs to the underwriters would require individual inquiries.302
Plaintiffs contend that the proposed Settlement Class definition addresses any previous concerns about ascertainability. All entities, other than natural persons, that received an initial allocation from the institutional pot have been excluded from the settlement classes. Because those who paid undisclosed compensation to the underwriters are a subset of the initial allocants, by excluding all of the initial allocants, all those who are alleged to have shared profits with the underwriters are also excluded from the class.303 Plaintiffs argue that defendants have produced lists of such excluded names during discovery and this proves that these entities are therefore identifiable.304 Although drawing up the remaining lists of eligible claimants will be difficult, they are certainly ascertainable.305 Plaintiffs have proven by a preponderance of the evidence that there is an identifiable class. I therefore find that all of the requirements of class certification have been met.
3. Section 11 Class
a. Class Period
In the 2004 Class Certification Opinion, I held that plaintiffs’ section class periods must be limited to “exclude all purchases *116made after untraceable securities entered the market.” 306 This is because “ ‘after market purchasers [must] trace their shares to an allegedly misleading registration statement [in order to] have standing to sue’ ” under section 11 of the Securities Act.307 If these cases were proceeding to trial, it would be necessary for the section 11 class periods to end at the time when unregistered shares became tradeable.
But because the parties have agreed to a settlement, there is no need to create a subclass for section 11 claims and shorten the class period. This is because the members of the section 11 class are also members of the section 10(b) class. The class includes all persons who “purchased or otherwise acquired any of the Subject Securities at issue in such case during the Settlement Class Periods applicable to such case and were damaged thereby.”308
b. Adequacy of Settlement Class Representatives
Plaintiffs have also informed the Court that “[n]ot every case has a proposed settlement class representative who is a member of the section 11 litigation class this Court previously defined.” 309 However, they argue that a separate section 11 settlement class representative is not necessary so long as the section 11 claim arises out of the “ ‘identical factual predicate’ ” as the settled conduct and there was “ ‘adequate representation’ ” of the claim, which is determined by the “‘alignment of interests of class members, not proof of vigorous pursuit of that claim.’”310 I agree. The section 11 claims arise from “a shared set of facts” as the Exchange Act claims for the class period proposed by the parties.311 I am further satisfied that the interests of the proposed settlement class representatives are aligned with those of any section 11 claimants. I hereby certify the proposed settlement classes.
B. Proposed Settlement
1. Settlement Discussions
The Court requested and the parties provided affidavits from retired Judges Nicholas Politan and Daniel Weinstein, the two mediators that assisted the parties to accept the terms of the instant settlement.312 Judges Politan and Weinstein have both attested that the settlement negotiations spanned nine months, included seven full mediation sessions, and countless phone conferences and other meetings with individual parties.313 In addition, they confirm that the terms were the product of arms’ length bargaining.314 They note specifically that “[c]ounsel on all sides were well-prepared, extremely knowledgeable about the facts and the law, and advocated vigorously for their client.”315 Thus, a presumption of fairness, adequacy, and reasonableness attaches to this settlement.316
*1172. The Grinnell Factors
Courts in this circuit look to the nine Grinnell factors to determine whether a settlement is “fair, reasonable and adequate” in accordance with Rule 23(e). I will evaluate each of the factors or group of factors in turn.
a. The Complexity, Expense and Likely Duration of the Litigation
It has been eight years since thousands of investors brought the class action lawsuits that are the subject of this consolidated action.317 These actions alleged that 55 underwriters, more than 300 issuers, and hundreds of individuals associated with these issuers defrauded the public.318 In an Order dated August 12, 2003, the actions were consolidated for pre-trial supervision by this Court, but ultimately, would have been re-assigned to judges in this district had the actions gone to trial.319 In addition, plaintiffs note that “a vast amount of additional factual and expert discovery remains to prepare for trials, and motions would be filed raising every possible kind of pre-trial, trial and post-trial issue conceivable.” 320 No one disputes that adjudication of these actions would have been a daunting task, and the expense and effort involved would certainly have been burdensome to the parties and the Court. This factor therefore weighs heavily in favor of preliminary approval.
b. Reaction of the Class to the Settlement
Plaintiffs have informed the Court that out of 309 actions, the lead plaintiff in only five of the actions disapproved of the proposed settlement.321 In those five actions, however, another class member who desires to serve as settlement class representative has approved the settlement.322 “‘Substitution of unnamed class members for named plaintiffs who fall out of the case because of settlement or other reasons is a common and normally an unexceptionable (routine) feature of class action litigation....”’ 323 It is too early to tell whether these five lead plaintiffs will lodge formal objections or whether more objectors will join in disapproving the settlement.324 Because of the uncertainty involved, this factor does not weigh for or against preliminary approval.
c. Stage of Proceedings and Amount of Discovery Completed
This factor is aimed at ensuring that the parties have a “thorough understanding of their case” prior to settlement.325 Litigation in this case has been ongoing for eight years. The Court has decided multiple motions to dismiss, considered numerous motions for class certification, and the parties have submitted more than a dozen expert reports, taken more than a hundred depositions, and reviewed tens of millions of pages in discovery.326 In addition, plaintiffs have informed the Court that they are “proposing this settlement with eyes open.” 327 I find that this factor weighs in favor of preliminary approval.
d. Risks of Class Prevailing (Establishing Liability, Damages, and Maintaining the Class Through Trial)
Plaintiffs concede that “[establishing lia*118bility is, at best, uncertain.” 328 They contend that defendants have denied any wrongdoing in the case, arguing that the tie-in agreements were really “underwriters gauging indications of interest as part of the IPO price discovery process.” 329 Plaintiffs admit that it is possible a jury might find defendants’ version of events to be more compelling, reducing their recovery to nothing.330 Plaintiffs also argue that if history is any indication, their chances of success at trial is — at best — -fifty percent.331
Even more complicated is the issue of loss causation and damages. Fischel has proposed a method of proving that the alleged scheme inflated stock prices as early as the beginning of trading and that this inflation dissipated throughout the class period.332 As discussed, defendants have challenged this proposed methodology during previous motions for class certification, submitting reports from a number of other experts in the field.333 There is a likelihood that defendants’ theories might be credited by the jury, thereby limiting the amount of recovery plaintiffs would receive.334
Finally, the maintenance of class certification in these cases through trial is fraught with risks. Plaintiffs inform the Court that defendants have compromised on several issues that defendants had previously argued would make these class actions unmanageable if they went to trial.335 In addition, decertification is always a likely possibility during trial in complex class actions such as these. These factors therefore weigh in favor of preliminary approval,
e. Ability of Defendants to Withstand a Greater Judgment
It cannot be disputed that the economic landscape has changed dramatically even in the last year, affecting the capability of many of the defendants to pay a large recovery in these actions. Plaintiffs note that one underwriter has already filed for bankruptcy and others have survived only with government assistance.336 It is unlikely that defendants would be able to withstand a greater judgment than the settlement amount that they have offered. It is therefore in plaintiffs’ best interests to resolve these actions, and quickly. This factor also weighs heavily in favor of preliminary approval.
f. Range of Reasonableness of Settlement Fund in Light of Best Possible Recovery and Attendant Risks of Litigation
The Second Circuit has held that a settlement that is within a range “ ‘that recognizes the uncertainties of law and fact in any particular case and the concomitant risks and costs necessarily inherent in taking any litigation to completion,’ ” will not be reversed on appeal.337 The Settlement Amount will undoubtedly be the most scrutinized part of the Stipulation. Potential objectors may argue that the $586 million settlement is much less than the one billion dollar guarantee that the Court had previously preliminarily approved in 2005 and is therefore outside of the “range of reasonableness.” However, a few points are worth noting.
First, to state the obvious, the one billion dollar guarantee was only a guarantee. None of the proceeds were to be distributed to putative class members until “after the conclusion of all of the above-mentioned proceedings with respect to the Underwriters.” 338 That guarantee differed substantial*119ly from the terms of the instant Stipulation. The guarantee required plaintiffs to continue to litigate their claims against the Underwriters.339 Forcing plaintiffs to litigate the matter until verdict would have been not only costly but uncertain. Only in the event that plaintiffs were unable to secure additional recovery from the Underwriters would they be entitled to any part of the one billion dollar guarantee. By contrast, the Stipulation provides that all Authorized Claimants, without condition, will be entitled to receive a portion of the recovery proceeds. Considering the risks I have already outlined with continuing these Actions, including the risks plaintiffs face establishing liability and damages and maintaining the class actions through trial, this settlement is reasonable.
Second, while the Settlement Amount is less than the potential recovery in the prior settlement in absolute terms, the class definition has been significantly narrowed. All investors who received IPO allocations from the “institutional pots” are now excluded from recovery, thereby severely limiting the number of potential claimants.340 As a result, although the “pie” might be smaller, each Authorized Claimant should receive a larger slice.
Finally, it cannot be discounted that the current economic environment has changed the “ball game” with respect to what plaintiffs could expect even with a verdict. As noted, one of the underwriters has filed for bankruptcy while a number of others have escaped a similar fate only because of government intervention. Simply put, plaintiffs cannot expect to receive a similar recovery to that they had hoped to receive during more bullish years. I therefore find that the settlement is within a range of reasonableness in light of possible recovery and upon consideration of the attendant risks in proceeding to trial.341
C. Form of Class Notice
Plaintiffs have submitted the proposed class notice to the Court for its review and consideration.342 Pursuant to the PSLRA, the proposed notice includes a cover page summarizing the required information and sections titled “Statement of Plaintiff Recovery,” “Statement of Potential Outcome of Case,” “Statement of Attorneys’ Fees and Costs Sought,” and “Reason for Settlement.”343 The proposed notice also identifies the members of the Plaintiffs’ Executive Committee.344 In addition, the proposed notice informs potential class members who is included in the class, how such persons would be eligible for payment, what they must do to claim payment, how to exclude themselves from the settlement class, and how to object to the settlement.345 Finally, while not required by law, the proposed notice also outlines the Plan of Allocation.346 I find that the proposed notice is sufficiently informative to advise potential class members of the terms of the proposed settlement and of the options available to them.
Regarding notification, plaintiffs have proposed mailing the notice first-class *120to each potential class member.347 In addition, the administrator will notify 2,000 brokers and nominee owners of the proposed settlement and request that they provide a list of beneficiaries or that they forward the notice on to their beneficiaries.348 Finally, the notice will be posted on a website that is maintained by the administrator and will be published in the national editions of the Wall Street Journal, USA Today, The New York Times, and over PR Newswire within ten days of the mailing.349 I find that notification by such means satisfies Rule 23 requirements and due process concerns and therefore approve it.350
D. Date of Fairness Hearing
A Settlement Fairness Hearing pursuant to Federal Rule of Civil Procedure 23(e) is scheduled to take place before the Court on September 10, 2009 at 4:30 p.m. The purpose of the Fairness Hearing is to finally determine (a) whether the actions satisfy the applicable prerequisites for class action treatment under Federal Rules of Civil Procedure 23(a) and (b) for the purposes of settlement; (b) whether the terms of the proposed settlement described in the Stipulation are fair, reasonable, and adequate, and should be approved by the Court; (c) whether the proposed Designations and Plan of Allocation is fair and reasonable and should be approved by the Court; (d) whether the Order and Final Judgment as provided under the Stipulation should be entered in each of the Actions, dismissing the Complaints on the merit s and with prejudice, and to determine whether the release of the settled claims, as set forth in the Stipulation, should be ordered; (e) whether the application of Lead Counsel for an award of attorneys’ fees and expenses should be approved; (f) whether the applications filed by proposed settlement class representatives and/or lead plaintiffs for their reasonable time and expenses incurred as a result of representing the proposed settlement classes should be approved; and (g) such other matters as the Court may deem appropriate.

. There are three general forms of the efficient capital markets hypothesis. First is the weak form, which asserts simply that the current share price in an efficient market reflects all information about past share prices. If the weak form of the hypothesis accurately describes a market, it is impossible to predict future prices using only past prices. Second, the semi-strong form, which asserts that a share price in an efficient market reflects all public information concerning the security (including but not limited to past share prices). Third, the strong form, which asserts that all relevant information, public and private, is reflected in the price of securities in an efficient market. The strong form has been widely discredited. See generally Daniel R. Fischel, Efficient Capital Markets, The Crash, and the Fraud on the Market Theory, 74 Cornell L.Rev. 907, 910-11 (1989). The semi-strong form is the form that generally concerns courts, and is the form to which I refer in this Opinion. See ATSI Commc'ns, Inc. v. Shaar Fund, Ltd., 493 F.3d 87, 100 n. 4 (2d Cir.2007) ("The efficient capital market hypothesis, as adopted by the Supreme Court, posits that 'the market price of shares traded on well-developed markets reflects all publicly available information.' ”) (quoting Basic, 485 U.S. at 246, 108 S.Ct. 978).

. In re WorldCom, Inc. Sec. Litig., 219 F.R.D. 267, 291 (S.D.N.Y.2003) (citing Affiliated Ute, 406 U.S. at 153-54, 92 S.Ct. 1456).
. 2004 Class Cert., 227 F.R.D. at 106. In doing so I also held, contrary to defendants' arguments, that Affiliated Ute applies to class actions, to claims in which both market manipulation and material omissions are alleged, and that Basic — far from disapproving of the reasoning in Affiliated Ute — specifically approved of the Affiliated Ute — presumption.
. Although the Second Circuit held that the Basic presumption could not apply during the IPO period in Miles I, it did not opine with respect to the applicability of the Affiliated Ute presumption. In Miles II, the court suggested that its holding in Miles I was limited to tire class proposed, by stating that "[n]othing in our decision precludes [plaintiffs] from returning to the District Court to seek certification of a more modest class....” 483 F.3d at 73. Plaintiffs have now narrowed the class so that all recipients of shares from the "institutional pot” would be excluded unless they are natural persons. They have also amended their master allegations to allege that the scheme was not widely known. See Am. Master Allegations ¶¶ 33, 35. The narrowing of the class therefore solves the predominance requirement with respect to knowledge and also ensures that plaintiffs can benefit from the Affiliated Ute presumption because they have excluded all those who were likely to have knowledge of the scheme.
. This first question appears to directly overlap with the merits of plaintiffs’ claims, but it does not. At the class certification stage, plaintiffs need not demonstrate loss causation. It is sufficient for plaintiffs to prove only that loss causation can be shown on a class-wide basis. Thus, as long as they have shown by a preponderance of the evidence that loss causation can be demonstrated on a class-wide basis by proving first, that inflation existed, and second, that the inflation dissipated slowly during the class period, this requirement is satisfied.

. See id. ¶¶ 6-7.
. See Fischel 2d Supp. Rep. ¶ 41.

See Cornell Rep. 14; see also 2004 Class Cert., 227 F.R.D. at 113 (discussing how Fischel’s methodologies have usually been utilized to determine damages, rather than loss causation). I also undertook a detailed analysis of the predominance requirement with respect to damages in my 2004 Class Certification Opinion, concluding that individual issues would not predominate over common questions. See 227 F.R.D. at 115-17. After reviewing that analysis, I find that plaintiffs have demonstrated by a preponderance of the evidence that damages can be calculated on a class-wide basis.
. See Stock Price Charts of Focus Case Stocks, Ex. C to Fischel 2d Supp. Rep. (showing that all of the focus case stocks had lost a significant amount of value by December 6, 2000, with some hovering just above zero).
. 2004 Class Cert., 227 F.R.D. at 114. Defendants previously argued that this holding is no longer viable in light of Dura Pharm., Inc. v. Broudo, 544 U.S. 336, 125 S.Ct. 1627, 161 L.Ed.2d 577 (2005). I disagree. Dura did not address the situation where the share price fell to virtually zero. In such a case, if inflation has been shown, it has clearly dissipated.
Dura teaches that loss causation cannot be inferred simply from a drop in prices. This is so because while the drop may have been caused by the defendants' wrongdoing, it may also have been caused by any number of factors. For example, assume the price of one share of a given company's stock is $80. The company makes a fraudulent positive announcement and the share price jumps to $100. At that point, an investor purchases one share. One week later, the price falls to $60. Dura cautions that these facts are insufficient to plead loss causation. The share price could have fallen because the market discovered the fraud, but it could also have fallen for many other reasons. See Dura, 544 U.S. at 342-43, 125 S.Ct. 1627 ("When the purchaser subsequently resells such shares, even at a lower price, that lower price may reflect, not the earlier misrepresentation, but changed economic circumstances, changed investor expectations, new industry-specific or firm-specific facts, conditions, or other events, which taken separately or together account for some or all of that lower price.”). It is possible that the fraudulent inflation has persisted (and that had the fraud not occurred, the share price would now be $40). Additional information is required to conclude that the fraud caused the loss.
However, Dura’s reasoning does not apply where a stock loses virtually all of its value. Imagine that after the investor purchases the share, the price falls from $100 to $0. At this point, there is no question that the $20 of fraudulent inflation has dissipated. Factors unconnected to the fraud may have caused $80 in loss, but the other $20 must be attributed to the dissipation of the inflation.

. A limit order is an order to buy or sell a security at a specific price. A limit order to purchase a set number of shares at $20 per share would be executed if and only if the shares could be purchased for $20 or less. If the market price never dropped to or below $20 per share, the order would never be executed. Limit orders tend to support prices because they affect purchases as the price falls. Limit orders are different from market orders, which are orders to buy at the current market price. A market order in a liquid stock will almost always be executed, but if prices are volatile the buyer might pay more than she intended.

Fischel also discusses the higher volume of aftermarket trading compared to the average trading volume of IPOs prior to the class periods, for IPOs not a part of this litigation during the class periods, and for IPOs after the class periods and that allocants of the lead underwriter were substantial net purchasers in the aftermarket. See Fischel 2d Supp. Rep. ¶¶ 27, 32. This tends to show only that tie-in agreements existed and suggests that prices may have been fueled by artificial demand.
. See Pfleiderer Rep. ¶ 44. See also Spiegel Rep. ¶ 9(2) ("Professor Fischel’s theory also ignores the possibility that the alleged ladderers themselves quickly sold the positions that they had purchased; such sales would also tend to offset any inflationary effect of the alleged laddering purchases.”); ¶ 34 ("[Ijnformation efficiency means that an ordinary investor endowed only with public information cannot earn a su-pernormal return on his investments. Thus, the scheme posited by Professor Fischel cannot succeed in a market that is information-efficient.”).

. Id. V 43. It appears that some of defendants' experts agree with this. See, e.g., Pfleiderer Rep. ¶ 38 (''[W]hen a buy trade takes place in an anonymous market, since market participants do not know whether the buyer is an 'informed' investor or not, they will attribute some probability to both possibilities. Hence the stock price may increase to reflect the possibility that the trade was motivated by information. However, if the buyer were uninformed, the price would revert over a short period of time once market participants realize that no fresh information is forthcoming that might justify the purchase as an informed trade.”); Stulz Rep. ¶ 22 ("If the market believes that an investor making a purchase might have private information favorable to the stock, the stock price will adjust to reflect the possibility of such favorable information. Similarly, however, when an investor believed to have private information sells shares, the market may conclude that the investor had unfavorable information and adjust the stock accordingly.”).
. Defendants’ expert Christopher Bariy agrees. He notes that "an analyst might highly recommend a stock with high forecasts of future earnings, and then not long afterward the company may report that earnings are, in fact, not in line with the analyst's high expectations. At that point in time, the stock price will generally reflect the actual earnings, and any price increase previously associated with the analyst's recommendation may be fully offset.” Bariy Rep. V 60. See also Bessembinder Rep. If 26 (“The reversal of any price impacts attributable to uninformed trades can occur because the market infers the truth from the absence of subsequent confirming information, because value-oriented traders detect the mispricing, or because the parties that originally traded (e.g., those who purchased due to tie-in agreements) elect to reverse their positions.").

This is a fundamental and crucial flaw.”). This was also the criticism of the Second Circuit in Akerman v. Oryx Commc'ns, Inc., when it opined that "[statistical analyses must control for relevant variables to permit reliable inferences.” 810 F.2d 336, 343 (2d Cir.1987) (citations omitted).

. Other criticisms related to the appropriate index to use or the time period over which the focus case stocks should be compared to the index are inconsequential. The Court need only be satisfied at the class certification stage that plaintiffs have identified a viable way to demonstrate loss causation on a class-wide basis. These determinations therefore need not be made at this stage.

In contrast, the alleged tie-in allocants had placed purchase orders with a weighted average limit price of only $13.93.”); Sirri Rep. ¶ 19 ("[I]n most (twelve out of fifteen) instances where the inside bid changed during the premarket period, there was at least one ‘wholesale’ market maker at the inside bid. This indicates that aggregate demand of mostly retail investors who had little or no opportunity to participate in the allocation of IPO shares had a large effect on opening price.”).

See Summary of Aftermarket Trading by Allo-cants with Alleged Tie-In Agreements, Ex. F to Fischel 2d Supp. Rep. In addition, the data indicates that in the first five days, allocants with alleged tie-in agreements were net purchasers, albeit by an even smaller percentage of issued shares. See id. At best, this data is inconclusive with respect to whether the alleged tie-in agreements had any effect on inflation in the aftermarket.

However, I have already held that plaintiffs' earlier pleadings are not conclusive admissions, though they may have evidentiary value. See In re Initial Public Offering Sec. Litig., 544 F.Supp.2d 277, 291 n. 96 (S.D.N.Y.2008). Defendants are correct that the Second Circuit's determinations in Miles I are binding on plaintiffs and on this Court. However, to the extent that plaintiffs have altered their allegations, those determinations may not be applicable. For example, Miles I concluded that based on defendants allegations concerning who knew of the manipulation, knowledge must have spread "throughout the community of market participants and watchers.” Miles I, 471 F.3d at 44. Because plaintiffs now allege that a substantially smaller number of participants knew of the manipulation, that finding no longer applies.

In that opinion, while I noted that I had previously certified a section 11 class with a shortened class period — finding that there were predominance and manageability issues related to answering the question of tracing — I found it unnecessary to shorten the class period and exclude post-tracing purchasers from the class at settlement. See id. at 194 — 95. I concluded that because the litigation was no longer going to trial, manageability was no longer an issue, and "the predominance defect [ ] no longer fatal.” Id. at 195.
