OPINION AND ORDER
SHIRA A. SCHEINDLIN, District Judge.1. INTRODUCTION1
This Court’s prior holdings establish that: (1) Vivendi Universal, S.A. (“Vivendi”) is precluded from contesting the elements of a Section 10(b) claim, save for reliance; (2) GAMCO Investors, Inc. (“GAMCO”) is entitled to the fraud on the market presumption, which shifts the burden to Vivendi to disprove reliance; and (3) Vivendi is precluded from raising the truth on the market defense to rebut the presumption of reliance. Based on these holdings, plaintiff GAMCO moves for summary judgment on its Section 10(b) claim against Vivendi on the grounds that discovery is complete, and no facts exist which disprove reliance.2 Vivendi opposes *248the motion. For the following reasons, the motion is denied.
II. FACTS3
On July 15, 2009, GAMCO filed an Amended Complaint alleging that Vivendi had violated Section 10(b) of the Securities Exchange Act of 1934 (the “Exchange Act”) with respect to GAMCO’s transaction in Vivendi’s American Depositary Receipts (“ADRs”), which traded on the New York Stock Exchange during the period October 30, 2000 through August 14, 2002 (the “Class Period”).4
On January 29, 2012, the jury in the class action In re Vivendi Universal S.A. Securities Litigation5 (the “Class Action”) returned its verdict, finding that Vivendi acted recklessly with respect to fifty-seven misstatements that “misstated or omitted Vivendi’s true liquidity risk.”6 On February 17, 2011, the Court entered a Memorandum Opinion and Order denying Vivendi’s post-trial motion for judgment as a matter of law as well as class plaintiffs’ motion for entry of final judgment.7 The Court stated that ‘Vivendi is entitled to rebut the presumption of reliance on an individual basis[,]” and that “any attempt to rebut the presumption of reliance on such grounds would call for separate inquiries into the individual circumstances of the class members.”8 Finally, on August 10, 2012, the Court entered an Opinion and Order collaterally estopping Vivendi from contesting, as to GAMCO, the Section 10(b) elements of falsity, materiality, scienter, and loss causation, and from raising the truth on the market defense to the presumption of reliance.9
Vivendi sets forth the following additional facts relevant to its opposition. GAM-CO, a wholly owned subsidiary of Gabelli Asset Management, Inc. (“GBL”), is an investment advisor with a broad spectrum of clients.10 The research arm of GBL, Gabelli & Company, performs research for GAMCO and other parts of GBL.11 GBL’s chairman and CEO is Mario Gabelli.12
GBL held daily morning meetings during which Gabelli & Company securities analysts presented research on the companies they covered to portfolio managers, *249client salesmen and client service representatives from GAMCO and other fund subsidiaries.13 During these meetings, GBL employees discussed investment ideas.14 GBL’s portfolio managers decided which securities to buy and sell on the basis of research provided by Gabelli & Company analysts.15
Vivendi presents evidence that GBL’s portfolio managers corresponded and/or met with Vivendi management, including Vivendi’s CEO Jean-Marie Messier, on multiple occasions during the relevant period.16 Specifically, Vivendi cites to the December 26, 2006 deposition of Caesar Bryan, a portfolio manager at GBL, and to the June 8, 2007 deposition of Mario Gabelli. Bryan states in his deposition that: “I’ve met with management of Vivendi on a number of occasions in which [sic] — over the past years.”17 When asked whom he meant by “management,” Bryan responded: “I mean, I have no recollection, but I visited Vivendi and I’ve heard presentations made by Vivendi management over the years.”18 The relevant portion of Gabelli’s deposition is quoted below:
Q. Have you ever met or corresponded with Jean-Marie Messier?
A. Yes.
Q. Did you meet with Jean Marie Messier during the relevant time period?
A. Maybe.
Q. Did you correspond with Messier during the relevant time period?
A. Maybe.
Q. Do you have any recollection of a specific conversation you had with Jean-Marie Messier during the relevant time period?
A. No.19
Furthermore, GAMCO employees occasionally participated in public Vivendi conference calls.20 Andrew Rittenberry was the Gabelli & Company analyst responsible for following Vivendi during the Class Period.21 In addition to following Vivendi, Rittenberry followed “all cable, media, and leisure companies.”22
Vivendi presents evidence that the only valuation metric used by GAMCO in connection with trading Vivendi was “private market value” (“PMV”).23 PMV is the amount that an informed industrialist would pay for a company’s assets in a private-market transaction.24 To determine the PMV of a company, Gabelli & Company used a spreadsheet to value each segment of the company as if it were an independent operation, and then added the *250value of the various segments to arrive at a total.25 Vivendi contends that the market price of a security is not one of the factors used in calculating PMV, but this is contested by GAMCO.26 In deciding whether to recommend a trade, the analysts’ main consideration is the difference between the PMV of the stock and its market price.27 GAMCO’s investment strategy was to purchase securities trading at a price below their PMV, in the expectation that the market price of the securities would eventually rise.28
III. SUMMARY JUDGMENT STANDARD
“Summary judgment is designed to pierce the pleadings to flush out those cases that are predestined to result in a directed verdict.”29 Thus, summary judgment is only appropriate “if the pleadings, the discovery and disclosure materials on file, and any affidavits show that there is no genuine issue as to any material fact and that the movant is entitled to judgment as a matter of law.”30 “For summary judgment purposes, a ‘genuine issue’ exists where the evidence is such that a reasonable jury could decide in the non-moving party’s favor.”31 “ ‘A fact is material when it might affect the outcome of the suit under governing law.’ ”32 “[T]he burden of demonstrating that no material fact exists lies with the moving party....” 33
In a summary judgment setting, “[t]he burden is on the moving party to demonstrate that no genuine issue respecting any material fact exists.”34 “When the burden of proof at trial would fall on the nonmoving party, it ordinarily is sufficient for the movant to point to a lack of evidence ... on an essential element of the nonmovant’s claim.”35 In turn, to defeat a motion for summary judgment, the non-moving party must raise a genuine issue of material fact.36 The non-moving party “ ‘must do more than simply show that there is some metaphysical doubt as to the material facts,’ ”37 and cannot “ ‘rely on conclusory allegations or unsubstantiated speculation.’ ”38
*251In deciding a motion for summary judgment, a court must “ ‘construe the facts in the light most favorable to the non-moving party and must resolve all ambiguities and draw all reasonable inferences against the movant.’ ”39 However, “ ‘[credibility determinations, the weighing of the evidence, and the drawing of legitimate inferences from the facts are jury functions, not those of a judge.’ ”40 “ ‘The role of the court is not to resolve disputed issues of fact but to assess whether there are any factual issues to be tried.’ ”41
IV. APPLICABLE LAW
A. Section 10(b) of the Securities Exchange Act and Rule 10b-5
Section 10(b) of the Exchange Act makes it illegal to “use or employ, in connection with the purchase or sale of any security ... any manipulative or deceptive device or contrivance in contravention of such rules and regulations as the Commission may prescribe....”42 Under Rule 10b-5, promulgated under Section 10(b), one may not “make any untrue statement of a material fact or [] omit to state a material fact necessary in order to make the statements made, in the light of the circumstances under which they were made, not misleading ... in connection with the purchase or sale of any security.” 43 “To sustain a private claim for securities fraud under Section 10(b), ‘a plaintiff must prove (1) a material misrepresentation or omission by the defendant; (2) scienter; (3) a connection between the misrepresentation or omission and the purchase or sale of a security; (4) reliance upon the misrepresentation or omission; (5) economic loss; and (6) loss causation.’ ”44
1. Reliance
The reliance and loss causation elements of a securities fraud claim are analogous to but-for and proximate causation, respectively.45 To prove reliance, the plaintiff must show that but for the material misleading statement or omission, he would not have transacted in the security. “The traditional (and most direct) way a plaintiff can demonstrate reliance is by showing that he was aware of a company’s statement and engaged in a relevant transaction — e.g., purchasing common stock— based on that specific misrepresentation.” 46
Additionally, the plaintiff must show that his reliance was reasonable.47 *252“An investor may not justifiably rely on a misrepresentation if, through minimal diligence, the investor should have discovered the truth. Under this standard, § 10(b) liability will not be imposed when an investor’s conduct rises to the level of recklessness.”48 The Second Circuit has not issued a definitive list of factors that weigh on the reasonableness of reliance, but it has provided the following list of relevant factors (the “Brown factors”):
(1) The sophistication and expertise of the plaintiff in financial and securities matters; (2) the existence of longstanding business or personal relationships; (3) access to the relevant information; (4) the existence of a fiduciary relationship; (5) concealment of the fraud; (6) the opportunity to detect the fraud; (7) whether the plaintiff initiated the stock transaction or sought to expedite the transaction; and (8) the generality or specificity of the misrepresentations.49
a. The Fraud on the Market Presumption
In Basic v. Levinson, the Supreme Court held that, under certain circumstances, a plaintiff is entitled to a rebuttable presumption (the “fraud on the market presumption”) that she relied on the integrity of the market price of a security.50 Specifically, the Court held that an investor who bought stock at market price may avail herself of the presumption that she “relied on the integrity of the price set by the market” if the market is efficient.51 The Court reasoned that “[bjecause 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.”52 As long as the “plaintiffs can show that the alleged misrepresentation was mater al and publicly transmitted into a well-developed market, then reliance will be presumed....”53 Basic’s holding obviated the need for a securities fraud plaintiff to show that she personally was aware of, and relied on, the alleged material misrepresentation.54
In short, “[t]he ... fraud-on-the-market theory involves two rebuttable presumptions that permit a finding of ... reliance ...: ‘that (1) misrepresentations by an issuer affect the price of securities traded in the open market, and (2) investors rely on the market price of securities as an accurate measure of their intrinsic value.’ ”55 As such, “[a]ny showing that severs the link between the alleged misrepresentation and either the price received (or paid) by the plaintiff, or [her] decision to trade at a fair market price, will be sufficient to rebut the presumption *253of reliance.”56
One way to “sever the link” is to demonstrate that the alleged misrepresentation did not impact the market price. For example, a defendant could show that the misstatement was known to be false by market makers,57 or that a statement correcting the misrepresentation was made to, and digested by, the market.58 Another way to sever the link is to show that the investor did not “rely on the market price of [the] seeurit[y] as an accurate measure of [its] intrinsic value.”59 For example, a plaintiff who transacts in a security despite having knowledge of the fraud cannot prove reliance.60
V. DISCUSSION
In opposing summary judgment, Vivendi argues that a reasonable jury could find that it has rebutted the fraud on the market presumption by finding that: (1) GAM-GO’s reliance was unreasonable because it either had, or should have had, reason to doubt Vivendi’s public statements;61 (2) GAMCO would have purchased Vivendi securities even if it had known of the fraud;62 or (3) GAMCO did not rely on the integrity of the market.63 I will address each argument in turn.
A. Vivendi Has Raised a Material Question of Fact With Respect to the Reasonableness of GAMCO’s Reliance
In this Circuit, “a plaintiffs reliance on the defendant’s misrepresentation must have been reasonable in order for the claim to proceed.”64 The reasonableness *254inquiry is straightforward when the plaintiff seeks to establish reliance directly.65 When a securities fraud claim is defeated for lack of reasonable reliance, the typical pattern is that the plaintiff had access to information which rendered reliance on the allegedly material misstatement unreasonable. In essence, then, the “reasonableness” prong of reliance merely recognizes that a plaintiff cannot willfully blind herself to a known risk.
When the plaintiff seeks to prove reliance through fraud on the market, this reasonableness inquiry applies only to the extent that corrective information was known either to the plaintiff or to the market.66 Fraud on the market entails reliance on the market price of a security, which fluctuates as the market incorporates the material misstatement or omission. Excepting cases of non-public information, it is hard to picture a circumstance where it would be unreasonable for a plaintiff to rely on the price of a security traded in an efficient market.67
A condition precedent to the fraud on the market presumption is that the misrepresentation was material, ie., that it would be expected to alter the price of the security. Defendants can therefore rebut this presumption by showing that the price was not affected by the misstatement or omission.68 One way of doing this is by showing that the falsity of the misrepresentation was already known to market makers, and, as such, the misrepresentation could not have been material.69 This is known as the “truth on the market” corollary to fraud on the market,70 and it is one form in which the “reasonable reliance” test survives under the fraud on the market presumption. The reasonable reliance test holds that the plaintiff cannot blind herself to a known risk, while the truth on the market defense assumes that known risks are priced into the market.
Vivendi is precluded from contesting the materiality of its misstatements by using the truth on the market defense to rebut the fraud on the market presumption.71 *255And, not surprisingly, Vivendi cites no case holding that a plaintiff who does not possess non-public information acted unreasonably in relying on the price of a security in an efficient market. Instead, Vivendi relies on the following three cases, all of which are inapposite: Jones v. Intelli-Check, Inc.;72 Cromer Finance Ltd. v. Berger;73 and In re ML-Lee Acquisition Fund II, L.P. & ML-Lee Acquisition Fund (Ret. Accounts) II, L.P. Securities Litigation.74
In Jones, the district court held that, under Third Circuit precedent, the plaintiff short-sellers were not entitled to the fraud on the market presumption, but could directly prove reliance by establishing the elements of fraud on the market.75 The Third Circuit, in a pre-Basic opinion, identified “the reasonableness of the reliance [on market price]” as one of the presumptions created by fraud on the market.76 Jones ultimately held that the plaintiffs could not prove reliance because, by their own admission, their awareness of the fraud — based on conflicting public statements — is what induced them to transact in the security.77 Jones, then, merely stands for the proposition that materiality cannot be shown when the plaintiffs have already digested corrective information. It is inapplicable here, however, because Vivendi is precluded from offering a truth on the market defense.78
In Cromer, a putative class brought an action against, among others, Deloitte & Touche Bermuda (“Deloitte”), the auditor of an offshore investment fund, alleging that Deloitte had issued clean audit reports for the fund despite having information that the fund’s net asset value statements (“NAV’s”) were fraudulent.79 The court in Cromer ultimately applied a presumption akin to the fraud on the market presumption, despite the fact that the market in question was not open or developed, because the auditors’ alleged misstatements ineluctably affected the price of the securities.80
*256Deloitte opposed class certification on the ground that information calling the reliability of the NAV’s into question had begun to circulate prior to the Class Period.81 Citing to the “reasonable reliance” line of cases cited above, the court in Cromer stated that: “the admitted sophistication of the investors weighs in favor of a heightened burden of diligence. While a jury will determine whether any failure by Haekl or Meijer-Werner [the putative class representatives] to engage in further inquiry was reckless or unjustified, nothing presented by Deloitte suffices to undermine the soundness of a presumption of reliance in this case.”82 Cromer, then, stands for the proposition that sophisticated investors cannot maintain an action for securities fraud in private-market transactions when they could have discovered the truth with minimal diligence. Here, GAMCO purchased Vivendi’s securities on the open market,83 and Vivendi is foreclosed from offering a truth on the market defense. Cromer is therefore inapposite.
Finally, ML-Lee, a District of Delaware case, holds that sophisticated plaintiffs in private-market transactions are held to a higher standard of due diligence and that, because the putative lead plaintiffs might be subject to unique defenses which would destroy the typicality requirement for class certification, defendants were entitled to discovery of the plaintiffs’ investment history.84 In ML-Lee, the court stated that “[plaintiffs’ sophistication may preclude a finding that the Plaintiffs relied on the alleged fraud in purchasing the securities.” 85 In other words, the “unique defense” that might be deployed against the lead plaintiffs relates to their actual reliance, not to whether it would be unreasonable to rely on the market price of a security.
Moreover, “almost all of the cases in which courts have found that a sophisticated investor had an enhanced duty to investigate involved face-to-face transactions, not purchases on an open securities market.” 86 This is the case because a rule requiring investors to independently investigate securities sold on the open market would vitiate the disclosure requirements of the Exchange Act.87 Such a rule would also be inefficient, as it would require buyers of securities to investigate matters *257known to the seller. The Seventh Circuit has drawn a useful analogy to the law of torts:
This is just another way to state the common law rule that contributory negligence is not a defense to an intentional or reckless tort. The best solution is for people not to harm others intentionally, not for potential victims to take elaborate precautions against such depradations. If the victims’ failure to take precautions were a defense, they would incur costs to take more precautions (and these costs are a form of loss victims would feel in every case, even if the tort does not occur), while would-be tortfeasors would commit additional torts because they would not fear the need to pay up in cases where the victims do not protect themselves. Common law courts have balked at such an outcome in ordinary tort cases, and securities law has followed the same path.88
In sum, sophisticated investors are not held to a higher standard of due diligence than ordinary investors when they purchase securities on the open market, as GAMCO did.89 Vivendi acknowledges that it is precluded from contesting materiality or introducing a truth on the market defense.90 However, Vivendi presents evidence that GAMCO’s analysts were experts in Vivendi’s industry and that they participated in, or read transcripts of, a number of meetings and conference calls with Vivendi’s management.91 On this basis, Vivendi argues that “[a] jury could find that GAMCO’s reliance was unreasonable either because GAMCO learned information during meetings or conference calls or from its own research that undermined Vivendi’s public statements, or because given what GAMCO knew from its research and experience, it should have asked questions that would have led to the truth.”92
To the extent that Vivendi’s argument is that GAMCO should have unearthed information that would have led it to discount Vivendi’s misrepresentations, such arguments fails because contributory negligence is not a defense to securities fraud. The argument that GAMCO could have unearthed such information, though, presents a fact issue for trial. GAMCO insists that the “fact that GAMCO did not trade while in possession of non-public information” is “undisputed.”93 However, Vivendi has presented evidence establishing that GBL employees privately corresponded and/or met with Vivendi management during the relevant time period.94 These employees went on to disavow any specific knowledge of the correspondences and meetings, but the credibility of such denials is a fact best determined at trial.
If GAMCO learned corrective nonpublic information from these meetings or correspondences, it would serve to rebut *258the fraud on the market presumption of reliance by demonstrating that GAMCO did not rely on the misstatements incorporated into the market price of Vivendi securities. Stated differently, GAMCO cannot claim that it reasonably relied on the market price of Vivendi securities if it knew that the securities’ price was inflated by fraud, but purchased them anyway.
In sum, Vivendi has presented enough evidence that GAMCO “ ‘had access to and knowledge of ” corrective information to withstand summary judgment.95 I therefore conclude that there is a material question of fact with respect to the reasonableness of GAMCO’s reliance.
B. Vivendi Has Raised Material Question of Fact as to Whether GAMCO Purchased Vivendi Securities Regardless of Their Market Price
Vivendi’s two remaining arguments opposing summary judgment are closely related. Vivendi argues that there is a material issue of fact with respect to reliance because: first, the brand of value-based investing that GAMCO applied to Vivendi did not take into account the price of Vivendi’s shares;96 and second, GAMCO in fact continued to purchase Vivendi shares after Vivendi’s fraud was exposed. Because these arguments are related, I will address them together.
It is somewhat ironic that GAMCO, a value-based investor, is relying on the fraud on the market presumption, which is grounded on the reliability of the market price that value-based investors spend their lives second-guessing. In support of its argument that GAMCO’s investment in Vivendi was not induced by the market price of Vivendi’s securities, Vivendi presents the statements of a number of GBL employees stating that PMV does not take market price into account.97 In support of its argument that GAMCO continued to invest in Vivendi after its fraud was revealed, Vivendi states that “[ajccording to Dr. Blaine Nye [plaintiffs’ expert in the Class Action], Vivendi’s true liquidity condition began to be revealed on January 7, 2002, when it announced that it would sell some of its treasury shares[,]”98 but GAM-CO increased its holdings in Vivendi after that date.
In fact, “GAMCO made its largest one-day purchase of Vivendi shares on July 2, 2002, a day on which Dr. Nye testified that Vivendi’s true liquidity condition was revealed by credit rating downgrades to junk status.”99 Citing to statements made by various GBL employees, Vivendi contends that GAMCO continued to invest in Vivendi after its liquidity condition had been revealed because its view of Vivendi’s underlying assets had not changed.100 As such, Vivendi argues that there is a material issue of fact with respect to whether *259GAMCO relied on the market price of Vivendi’s shares.
In response, GAMCO argues that Vivendi’s “subjective belief that a security’s market price is undervalued is [in]sufficient to destroy [GAMCOJ’s reliance on the integrity of the market[,]” because every investor thinks the securities they transact in are over- or under-valued.101 Relatedly, GAMCO alleges that it did, in fact, rely on the market price of Vivendi’s securities, insofar as it thought that Vivendi’s securities were undervalued.102 Building on this point, GAMCO cites a District of Rhode Island case for the proposition that “[t]he mere fact that different ‘traders have divergent motivations in purchasing shares should not defeat the fraud-on-the-market presumption absent convincing proof that price played no part whatsoever in their decision making.’ ”103
According to GAMCO, the relevant inquiry is whether it would have entered the same transactions at the same prices absent Vivendi’s fraud; whether GAMCO would have entered into different transactions at different prices is of no moment.104 And because Vivendi “merely speculates that, had the market known the truth of the fraud!,] • • • GAMCO would have likely entered into different transactions (at lower prices) for the same Vivendi securities!,]” GAMCO concludes that there is not a material dispute of fact with respect to GAMCO’s reliance on the market price.105
GAMCO further argues that it did not rely solely on PMV when it decided to invest in Vivendi and that, in any case, PMV is not insensitive to accounting fraud. In support of the first point, GAMCO quotes the June 25, 2007 deposition of Mario Gabelli, in which Gabelli states that GAMCO “[would determine if Vivendi securities were undervalued] ... using a variety of stock specific dynamics ... [including] [e]arnings per share, PMV, EBITDA [ (earnings before income, tax, depreciation, and amortization) ] ... a whole mosiac.”106 In support of the second point, GAMCO quotes the October 20, 2006 deposition of one of its portfolio managers, who stated that “ ‘[PMV] relies very heavily on the integrity of the financial statements of the companies [a portfolio manager] ... is looking at.... [I]f anybody is cooking the books ... the methodology doesn’t work very well.’ ”107 Finally, GAMCO contends that its post-disclosure purchases of Vivendi securities do not rebut the presumption of reliance because “the Class Action jury necessarily determined that the market price of Vivendi [securities] decreased following each material partial disclosure!,]”108 meaning that GAMCO still relied on the market price following each disclosure. In support of this position, GAMCO cites to three cases that state that “averaging down”— i.e., purchasing additional shares of a security that has decreased in value — does not *260create an atypical defense, defeating class certification when reliance is based on a fraud on the market theory.109 GAMCO concedes that the first corrective disclosure was on January 7, 2002, but points out that less than one-third of GAMCO’s Vivendi purchases were made after January 7, 2002.110
As an initial point, it bears repeating that class certification and the class jury trial have passed, and that the current posture of the instant case involves Vivendi’s challenge to GAMCO’s reliance. The February 17 Opinion notes that questions of individual reliance will not defeat class certification when a trial on common issues is possible, but rather will “call for separate inquiries into the individual circumstances of particular class members.”111 This is one such “separate inquir[y].” As such, the cases cited by GAMCO that relate to whether to certify a securities fraud class are inapposite at this stage in the litigation,112 because they stand only for the proposition that ‘“the extent of any non-reliance ... [is] a fact question to be decided at trial....’”113 In other words, an investor’s lack of reliance on the market price and/or post-disclosure purchases may not defeat the typicality requirement for class certification. But that does not imply that non-class plaintiffs may assert res judicata on the reliance issue as soon as a class has been certified.
Equally inapposite are GAMCO’s citations to a line of cases that stand for the proposition that short-sellers are entitled to the fraud on the market presumption, despite the fact that short-sellers buy securities that they think are undervalued.114 At best, these cases establish only that plaintiffs who trade in securities that they believe are undervalued may, as a matter of law, invoke the fraud on the market presumption. They do not speak to how that presumption may be rebutted.115 And *261they do not imply that, absent insider information, the fraud on the market presumption is irrebuttable as against any investor who purchased a security at market value, as GAMCO at times appears to argue.116
At its core, GAMCO’s argument is that Vivendi has not raised a material issue of fact because it has not shown that: (1) GAMCO would have entered the same transactions, at the same prices, absent the material misstatements; or that (2) GAMCO’s post-disclosure transactions in Vivendi securities were not made in reliance on the integrity of the market price. As to the first point, it is true that courts at times use the formulation that the fraud on the market presumption can be rebutted if “defendant can show that plaintiff would have purchased the stock at the same price even if [s]he had [ ] known the non-disclosed information....”117 However, Vivendi has presented evidence — from the analyst charged by GBL with following Vivendi during the Class Period — that “the impact of Vivendi’s liquidity crisis on GAMCO’s PMV calculation would be ‘minor.’ ”118 This is enough to raise a material question of fact as to whether GAMCO would have transacted in Vivendi securities even if it had known its true liquidity condition. As discussed above, GAMCO disputes whether it actually relied solely on PMV as well as the extent to which PMV is insensitive to accounting fraud. But this just supports my conclusion that reliance is an issue for trial.
All of the cases cited by GAMCO in support of the second point119 reflect the rule that “that post-disclosure purchases will not prevent an investor from relying on the integrity of the market for predisclosure purchases[,] ... [because] [a]n investor who purchases a security after the disclosure of adverse information still relies on the fact that the newly released information will be absorbed by the market and therefore reflected in the post-disclosure price.”120 Specifically, these cases hold that post-disclosure purchases of securities do not necessarily rebut the fraud on the market presumption as a matter of law, meaning that classes can be certified despite the presence of members who made post-disclosure purchases.121 The cases do not imply that post-disclosure purchases are never relevant to the plaintiffs reliance.
GAMCO acknowledges that post-disclosure purchases can defeat the typicality requirement for class certification when “plaintiffs made a ‘disproportionately large percentage’ of their purchases post-disclosure ....”122 And the same result obtains “when a disclosure is so forceful that it becomes unreasonable for an investor, or the market, to continue to be misled by the *262defendants’ alleged misrepresentation.”123 By the same logic, it stands to reason that GAMCO’s post-disclosure purchases of Vivendi securities are probative of whether GAMCO’s investment strategy took market price into account. GAMCO alleges that it “executed less than one-third of its total Class Period Vivendi ADR purchases, measured by volume, after the date of the first partial corrective disclosure....”124 Once more, this merely strengthens the point that a material issue of fact exists.
In sum, Vivendi has raised a material question of fact as to whether GAMCO actually relied on the market price of Vivendi’s securities when it invested in Vivendi. GAMCO’s post-disclosure purchases are probative of that reliance, or the lack thereof. Therefore, GAMCO’s motion for summary judgment is denied.
VI. CONCLUSION
For the foregoing reasons, GAMCO’s motion for summary judgment is denied. The Clerk of Court is directed to close this motion (Docket No. 105).
