Power And Statistical Significance In Securities Fraud Litigation, Jill E. Fisch, Jonah B. Gelbach

All Faculty Scholarship

Event studies, a half-century-old approach to measuring the effect of events on stock prices, are now ubiquitous in securities fraud litigation. In determining whether the event study demonstrates a price effect, expert witnesses typically base their conclusion on whether the results are statistically significant at the 95% confidence level, a threshold that is drawn from the academic literature. As a positive matter, this represents a disconnect with legal standards of proof. As a normative matter, it may reduce enforcement of fraud claims because litigation event studies typically involve quite low statistical power even for large-scale frauds.

The Logic And Limits Of Event Studies In Securities Fraud Litigation, Jill E. Fisch, Jonah B. Gelbach, Jonathan Klick

All Faculty Scholarship

Event studies have become increasingly important in securities fraud litigation after the Supreme Court’s decision in Halliburton II. Litigants have used event study methodology, which empirically analyzes the relationship between the disclosure of corporate information and the issuer’s stock price, to provide evidence in the evaluation of key elements of federal securities fraud, including materiality, reliance, causation, and damages. As the use of event studies grows and they increasingly serve a gatekeeping function in determining whether litigation will proceed beyond a preliminary stage, it will be critical for courts to use them correctly.

Halliburton Ii: A Loser's History, Adam C. Pritchard

Articles

The Supreme Court was presented with an opportunity to bring fundamental reform to securities class actions last term in Halliburton Co. v. Erica P John Fund, Inc.. The Court ducked that opportunity, passing the buck to Congress to undo the mess that the Court had created a quarter century prior in Basic Inc. v. Levinson. Congress's history in dealing with securities class actions suggests that reform is unlikely to come from the legislature anytime soon. The Securities and Exchange Commission appears to be satisfied with the status quo as well. With these institutional actors resisting reform, corporations and …

Corporate Governance In The Courtroom: An Empirical Analysis, Jessica M. Erickson

Law Faculty Publications

Conventional wisdom is that shareholder derivative suits are dead. Yet this death knell is decidedly premature. The current conception of shareholder derivative suits is based on an empirical record limited to suits filed in Delaware or on behalf of Delaware corporations, leaving suits outside this sphere in the shadows of corporate law scholarship. This Article aims to fill this gap by presenting the first empirical examination of shareholder derivative suits in the federal courts. Using an original, hand-collected data set, my study reveals that shareholder derivative suits are far from dead. Shareholders file more shareholder derivative suits than securities class …

What Counts As Fraud? An Empirical Study Of Motions To Dismiss Under The Private Securities Litigation Reform Act, Adam C. Pritchard, Hillary A. Sale

Articles

This article presents the findings of a study of the resolution of motions to dismiss securities fraud lawsuits since the passage of the Private Securities Litigation Reform Act (PSLRA) in 1995. Our sample consists of decisions on motions to dismiss in securities class actions by district and appellate courts in the Second and Ninth Circuits for cases filed after the passage of the Reform Act to the end of 2002. These circuits are the leading circuits for the filing of securities class actions and are generally recognized as representing two ends of the securities class action spectrum. Post-PSLRA, the Second …

In Re Silicon Graphics Inc.: Shareholder Wealth Effects Resulting From The Interpretation Of The Private Securities Litigation Reform Act's Pleading Standard, Marilyn F. Johnson, Karen K. Nelson, Adam C. Pritchard

Articles

This Article presents an empirical study of changes in shareholder wealth resulting from the Ninth Circuit Court of Appeals decision in In re Silicon Graphics Inc. Securities Litigation, which interpreted the pleading provision established in the Private Securities Litigation Reform Act of 1995 (the "Reform Act"). Congress passed the Reform Act as part of an ongoing effort to protect corporations from abusive suits alleging "fraud by hindsight." In such suits, plaintiffs claimed that a sudden drop in a company's stock price was evidence that the issuer and its management covered up the bad news that led to the price drop. …

Fraud And Federalism: Preempting Private State Securities Fraud Causes Of Action, Michael A. Perino

Faculty Publications

The passage of the Private Securities Litigation Reform Act of 1995 has engendered a significant forum shift in class action securities fraud litigation, from federal to state court. This unintended by-product of the Act has reignited debate over our dual federal-state system of securities regulation and in turn has inspired a discussion as to whether Congress should now preempt state securities fraud causes of action. This article argues that preemption is an appropriate, but not the only, solution to these concerns. To support this argument, this article first traces the history of dual state-federal securities regulation within the context of …

Contracting Access To The Courts: Myth Or Reality? Bane Or Boon?, Jeffrey W. Stempel

Scholarly Works

Many scholars of the dispute resolution system perceive a sea change in attitudes toward adjudication that took place in the mid-1970s. Among the events of the time included the Pound Conference, which put the Chief Justice of the United States and the national judicial establishment on record in favor of at least some refinement, if not restriction, on access to courts. In addition, Chief Justice Burger, the driving force behind the Pound Conference, also used his bully pulpit as Chief Justice of the Supreme Court to promote ADR, particularly court-annexed arbitration. The availability of judicial adjuncts such as court-annexed arbitration …
