First it computes the long-run excess returns of the IPOs with types of models. Then it examines whether the underperformance has statistical significance or not. After that, it analyzes the relationship between the variables and long-run performance of IPOs.
Research documents that the IPOs significantly underperformed the matched companies. The cumulative abnormal returns over the three years listing are -0.18446. The buy and hold abnormal returns over three years after listing are-0.01284. At last, using the cross-sectional analysis to analyze the factors that affect the long-run performance of IPOs, the regression result shows that EPS is the basic reason; the intrinsic value, issue characteristics and the investors’ sentiment (overoptimistic) are the main reason for long-run performance of IPOs.
