Facts

Plaintiffs alleged Halliburton made public misrepresentations concerning asbestos liability and accounting for fixed-price construction contracts, which inflated Halliburton's stock price. Plaintiffs sought certification of a class running from July 22, 1999 to December 7, 2001 and relied on six alleged corrective disclosures: December 21, 2000; June 28, 2001; August 9, 2001; October 30, 2001; December 4, 2001; and December 7, 2001. On remand, both sides submitted expert event studies on price impact. Halliburton argued the alleged disclosures either did not affect price or that any price movement was attributable to other factors, thereby rebutting the Basic presumption of classwide reliance.

Issue

At class certification, did Halliburton rebut the Basic fraud-on-the-market presumption by proving lack of price impact as to plaintiffs' alleged corrective disclosures? Relatedly, who bears the burdens of production and persuasion on price impact, and may the court decide at certification whether the alleged disclosures were legally corrective?

Rule

At class certification, a defendant may rebut the Basic presumption with evidence that the alleged misrepresentation or its correction did not affect the market price. In this court's view, both the burden of production and the burden of persuasion on lack of price impact rest on the defendant. The certification-stage inquiry concerns price impact, not whether the disclosure was legally corrective, and in an efficient market price impact must ordinarily appear when the information reaches the market rather than on a later trading day absent a compelling explanation.

One of 10 multiple-choice questions for this case. Pick an answer to see why.
Investors seek Rule 23(b)(3) certification in a Section 10(b) action against Redwood Basin Robotics, a fictional manufacturer headquartered in San Jose, California. The plaintiffs show public statements, an efficient market, and trading during the proposed class period; Redwood Basin then offers an event-study expert opining that the alleged corrective announcement had no price impact, while plaintiffs offer a competing expert finding impact.

At class certification, who bears the burden of persuading the court on the issue of lack of price impact?

Explanation. The court placed both the burden of production and the burden of persuasion on the defendant seeking to rebut the Basic presumption at class certification. Its reasoning was that forcing plaintiffs to persuade the court on price impact would effectively require direct proof of price impact at certification and would substantially undercut the presumption of classwide reliance. So where experts conflict, the defendant must ultimately persuade the court that its evidence is more probative. (Derived from Erica P. John Fund, Inc. v. Halliburton Co. (n.d.).)
