We compare the trading performance of independent directors and other officers of the firm. We find that independent directors earn positive and substantial abnormal returns when they purchase their company stock, and that the difference with the same firm's officers is relatively small at most horizons. The results are robust to controlling for firm fixed effects and to using a variety of alternative specifications. Executive officers and independent directors make higher returns in firms with the weakest governance and the gap between these two groups widens in such firms. Independent directors who sit on the audit committee earn higher return than other independent directors at the same firm. Finally, independent directors earn significantly higher returns than the market when they sell the company stock in a window before bad news and around earnings restatements.
