In a large sample of shareholder initiated class action lawsuits from 1996 to 2011, we find a significant increase in informed insider option exercises during the class action period compared to the preceding quarter, and we find that this change is positively related to the probability of litigation. The market reaction to the announcement of lawsuits is negatively related to abnormal informed option exercises, but positively related to suits that ultimately get dismissed. These results suggest that the market can at least partially anticipate the merits and severity of the class action suit. In subsequent analyses, we find that CEO turnover is positively related to litigation, but not option exercises. Collectively, our results indicate that insiders knowingly trade on their private information.

We demonstrate that time stamps reported in I/B/E/S for analysts’ recommendations released during trading hours are systematically delayed. Using newswire‐reported time stamps, we find 30‐minute returns of 1.83% (−2.10%) for upgrades (downgrades), but for this subset of recommendations we find corresponding returns of −0.07% (−0.09%) using I/B/E/S‐reported time stamps. We also examine the information content of recommendations relative to management guidance and earnings announcements. Our evidence suggests that analysts’ recommendations are the most important information disclosure channel examined.
