This paper implements a comprehensive study on the long run post-issue operating performance of more than 700 initially public offerings (IPOs) in the Japanese over-the-counter market (JASDAQ) from 1991 to 2001. Empirical results document dramatic and continuing operating underperformance that are robust to industry or mean reversion adjustment. The diagnostic tests for behavioral explanations further uncover the salient decline of market expectations by various measures over the post issuing years, as well as the upsurge in company expansion around the offering years followed by the striking dwindle soon afterwards. These findings jointly shed light on the systematic over-optimism of market investors and managers at the time of IPO events. The multiple regression analysis also demonstrates robust evidence that is favorable for the hypotheses of "Windows of Opportunity" and market timing. In contrast, we do not find that there are significant associations between changes in alternative insider ownership and the evolution of operating performance. We suggest the explanations based on the agency problem theory are not effective in explaining the long run operating underperformance of JASDAQ IPOs. © Springer 2005.
