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 Article characterizes this collaboration as a lawmaking partnership and argues that such a partnership offers distinctive lawmaking advantages. …

Securities Law And The New Deal Justices, Adam C. Pritchard, Robert B. Thompson

Articles

In this Article, we explore the role of the New Deal Justices in enacting, defending, and interpreting the federal securities laws. Although we canvass most of the Court's securities law decisions from 1935 to 1955, we focus in particular on PUHCA, an act now lost to history for securities practitioners and scholars. At the time of the New Deal, PUHCA was the key point of engagement for defining the judicial view toward New Deal securities legislation. Taming the power of Wall Street required not just the concurrence of the legislative branch, but also the Supreme Court, a body that the …
