Title: Go down fighting
Description: "I study battles between short sellers and firms.  Firms use a variety of methods to impede short selling, including legal threats, investigations, lawsuits, and various technical actions intended to create a short squeeze.  These actions create short sale constraints.  Consistent with the hypothesis that short sale constraints allow stocks to be overpriced, firms taking anti-shorting actions have in the subsequent year very low abnormal returns of about -2 percent per month"--National Bureau of Economic Research web site.
