What Do Independent Directors Know? Evidence from Their Trading

Enrichetta Ravina and Paola Sapienza

The Review of Financial Studies, 2010, vol. 23, issue 3, 962-1003

Abstract: We compare the trading performance of independent directors and other executives. The findings reveal that independent directors earn positive substantial abnormal returns when they purchase their company stock, and that the difference from the same firm's executives is relatively small at most horizons. We also find that executives and independent directors make higher returns in firms with the weakest governance, the gap between these two widens in such firms, and that independent directors sitting on the audit committee earn higher returns than other independent directors at the same firm. Independent directors also earn significantly abnormal returns when they sell the company stock in a window before bad news and around earnings restatements. The Author 2009.
