Fact or Fiction: Flawed Approaches to Evaluating Market Behavior in Securities Litigation

If you follow this blog regularly, you’ve probably seen me rant about the myriad errors courts make when evaluating market and investor behavior in the context of securities litigation.  I finally did what I’d been threatening to do and compiled my complaints into a single Essay on the subject, which I presented at the Connecting the Threads symposim hosted by the University of Tennessee at Knoxville in September.  (The symposium featured all of the Business Law Prof bloggers, and Marcia posted a description of the full program here)

My Essay, along with pieces by my co-bloggers, will be published in Transactions: The Tennessee Journal of Business Law.  I’ve just posted a draft to SSRN, and – anyway, here’s Wonderwall:

Fact or Fiction: Flawed Approaches to Evaluating Market Behavior in Securities Litigation

Abstract: Courts entertaining class actions brought under Section 10(b) of the Securities Exchange Act are required to make numerous factual judgments about the economic effects of the alleged misconduct.  For example, they must determine whether and for how long publicly-available information has exerted an influence on security prices, and whether an alleged fraud caused economic harm to investors.  Judgments on these matters dictate whether cases will proceed to summary judgment and trial, whether classes will be certified and the scope of such classes, and the damages that investors are entitled to collect.   

Over the years, courts have developed a variety of common law doctrines to guide these inquiries.  As this Essay will demonstrate, collectively, these doctrines operate in such an artificial manner that they no longer shed light on the underlying factual inquiry, namely, the actual effect of the alleged fraud on investors.  The result is that determinations of market impact and investor loss have become, in a real sense, fictional: the size and effects of the fraud are determined based on abstract doctrine rather than any empirical assessment of market behavior.  Ultimately, these stylized approaches to assessing market evidence interfere with the ability of the Section 10(b) cause of action to fulfill its modern function as a mechanism for deterring fraud. 

This Essay therefore recommends that, to the extent possible, these inquiries should be replaced with alternative schemes that award damages based on some combination of statutory formulas and evidence of investors’ reliance on the fraud.  These alternatives would be easier for courts to administer, and would re-align the fraud-on-the-market action with its fundamental goals.
