Abstract

This paper investigates insider trading activities in German stocks during the first year following implementation of the new Insider Law on 1 July 2002. It can be observed that insiders act as contrarian investors. They buy stocks after prices have fallen and sell stocks after prices have risen. In general, insider trades are very profitable. A typical stock purchased by an insider yields an abnormal return of almost 3 per cent during the 25 days following the transaction. In contrast, a typical stock that has been sold by insiders achieves an abnormal return of nearly -3 per cent over the same time period. Outsiders who copy the transactions of insiders can achieve nearly the same abnormal returns. Abnormal returns remain substantial even after transaction costs. The results suggest that prices of stocks in which insiders trade do not seem to be semi-strong efficient.
