The IPO Investigations: Who's the Victim? What's the Harm?
by John C. Coffee Jr.
John C. Coffee Jr. is the Adolf A. Berle Professor of Law at Columbia University Law School. This article was written while Professor Coffee was also serving as the Joseph Flom Visiting Professor of Law at Harvard University Law School

includes items like:

· The First-Day Price Spike Puzzle

· The Allocation Issue

· Pushing the Envelope

· Who Is the Victim?

· Other Victims: Retail Investors

..."Another constituency may be even more adversely affected by current practices. This group consists of those investors who do buy in the secondary market, either on the first trading day or shortly thereafter. Typically, these are persons who did not receive an IPO allocation (or only a small one). The best known empirical regularity about IPOs is that the issuer's stock price tends to decline at some point during the year following the initial price spike, often to a level below the initial offering price. Thus, those who buy in the secondary market immediately following the IPO tend to lose.
