| Abstract: | This empirical study examines whether the optimistic forecasts of analysts explain the long-run abnormal return (here as: ab-ret.) following initial public offerings (IPOs). Consistent with prior research, this paper concludes that the analysis of earning forecasts for firms going public has an upward bias. While the usually calculated buy-and-hold ab-ret. is not significantly negative on average, a proper control for risk confirms the long-run underperformance hypothesis for the 1-year period following IPOs. The risk-adjusted return is positively correlated to the surprise effect and earning forecast revisions, and appears to be the response to new information about the true earnings perspectives. |
