Narrative Opinion Summary
In this case, the plaintiffs alleged securities fraud against the defendants, asserting that fraudulent activities inflated the company's stock price during the specified class period. They filed a motion to exclude the testimony of the defendants' expert, Dr. Bradford Cornell, regarding loss causation. The court examined the admissibility of Dr. Cornell's testimony under Federal Rule of Evidence 702, applying the Daubert standard to assess its reliability and relevance. The plaintiffs contested Dr. Cornell's interpretation of loss causation, arguing it was inconsistent with Ninth Circuit precedent, which does not require corrective disclosures to label practices as fraudulent for establishing loss causation. The court found Dr. Cornell's conclusions flawed because they relied on an incorrect legal standard, as the Ninth Circuit requires only that the market reacts to the revelation of misrepresented facts. The court granted the plaintiffs' motion to exclude Dr. Cornell's testimony, noting the testimony did not meet the appropriate legal standards. This decision was informed by relevant case law, including Dura Pharmaceuticals Inc. v. Broudo, and was consistent with the testimony of another expert, Dr. Tabak, who contradicted Dr. Cornell's interpretation. The exclusion of Dr. Cornell's testimony significantly impacted the defendants' ability to contest the plaintiffs' claims regarding loss causation.
