We examine the nature of information contained in insider trades prior to corporate events. Insiders’ net buying increases before open market share repurchase announcements and decreases before seasoned equity offers. Higher insider net buying is associated with better post-event operating performance, a reduction in undervaluation, and, for repurchases, lower post-event cost of capital. Insider trading also predicts announcement returns and long-term stock price drift following events. Overall, our results suggest that insider trades before corporate events contain information about changes both in fundamentals and in investor sentiment.
