The effect of investor attention on fraud discovery and value loss in securities class action litigation

Abstract

AbstractWe examine the effect of investor attention on value loss due to securities class action lawsuits and litigation‐based fraud discovery. We find that investor attention is positively associated with damage to corporate reputation and the magnitude of the value losses suffered by defendant firms. The reputational damage to defendant firms with higher investor attention is evident from poor operational performance and lower institutional ownership after filing. Investor attention is positively associated with the diffusion of information regarding fraud and it accelerates lawsuit filing. The effects of investor attention, however, are not subsumed by the severity of the fraud. Our results are robust to a battery of tests that addresses selection and endogeneity concerns.
