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.

Rule 10b-5’s antifraud catch-all is one of the most consequential pieces of American administrative law and most highly developed areas of judicially-created federal law.

The Court reasoned that adherence to Basic was warranted by principles of stare decisis that operate with “special force” in the context of statutory interpretation. This Article offers an alternative justification for adhering to Basic—the collaboration between the Court and Congress that has led to the development of the private class action for federal securities fraud. The Article characterizes this collaboration as a lawmaking partnership and argues that such a partnership offers distinctive lawmaking advantages. …

The Long Road Back: Business Roundtable And The Future Of Sec Rulemaking, Jill E. Fisch
All Faculty Scholarship
The Securities and Exchange Commission has suffered a number of recent setbacks in areas ranging from enforcement policy to rulemaking. The DC Circuit’s 2011 Business Roundtable decision is one of the most serious, particularly in light of the heavy rulemaking obligations imposed on the SEC by Dodd-Frank and the JOBS Act. The effectiveness of the SEC in future rulemaking and the ability of its rules to survive legal challenge are currently under scrutiny.
This article critically evaluates the Business Roundtable decision in the context of the applicable statutory and structural constraints on SEC rulemaking. Toward that end, the essay questions …
