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.

The Future Of Securities Class Actions Against Foreign Companies: China And Comity Concerns, Dana M. Muir, Junhai Liu, Haiyan Xu

University of Michigan Journal of Law Reform

In Morrison v. National Australia Bank Ltd., the U.S. Supreme Court limited the application of U.S. securities fraud law in transnational situations. The Supreme Court noted that its decision was influenced by international comity considerations. In this Article, we evaluate the availability of class actions in China in cases involving alleged securities fraud. Because we find that the availability of those actions is too limited to fully protect U.S. shareholders, we argue that U.S. investors should be permitted to bring securities fraud class actions against non-U.S. companies whose securities are traded on a U.S. exchange regardless of where those investors …

“Fine Distinctions” In The Contemporary Law Of Insider Trading, Donald C. Langevoort

Georgetown Law Faculty Publications and Other Works

William Cary’s opinion for the SEC in In re Cady, Roberts & Co. built the foundation on which the modern law of insider trading rests. This paper—a contribution to Columbia Law School’s recent celebration of Cary’s Cady Roberts opinion, explores some of these—particularly the emergence of a doctrine of “reckless” insider trading. Historically, the crucial question is this: how or why did the insider trading prohibition survive the retrenchment that happened to so many other elements of Rule 10b-5? It argues that the Supreme Court embraced the continuing existence of the “abstain or disclose” rule, and tolerated constructive fraud notwithstanding …

Extraterritoriality As Standing: A Standing Theory Of The Extraterritorial Application Of The Securities Laws, Erez Reuveni

Erez Reuveni

This Article contends that the current treatment of the extraterritorial scope of the 1934 Securities Exchange Act as a question of subject matter jurisdiction is wrong. Although the Act is silent as to its extraterritorial application, for over forty years courts have analyzed the Act’s extraterritorial scope as a question of subject matter jurisdiction, relying on the so-called “conduct” and “effects” tests. Because courts apply these tests in an ad hoc, case-by-case manner, they are inherently unpredictable and unnecessarily complicated. This state of affairs has become particularly troublesome in recent years, as so-called “foreign-cubed” securities fraud lawsuits - lawsuits filed …

Insider Trading And The Gradual Demise Of Fiduciary Principles, Donna M. Nagy

Articles by Maurer Faculty

Recent SEC enforcement actions, such as the case filed against Dallas Mavericks' owner Mark Cuban, raise the question whether deception by a fiduciary is essential to the Rule 10b-5 insider trading offense. Under the Supreme Court's classical and misappropriation theories, the answer is clearly yes - each theory has a fiduciary principle at its core. Yet lower courts and the SEC frequently disregard the Court's explicit dictates, and a consensus is emerging that insider trading rests simply on the wrongful use of material nonpublic information, regardless of whether a fiduciary-like duty is breached. Although this view of insider trading can …
