摘 要：

Prior research shows that IPOs impact the prices of other stocks that are closely correlated with the IPOs. We go one step further to examine whether sizable IPOs affect the market as a whole. Using an IPO sample from China, we find robust evidence that sizeable IPOs do depress the market return as a whole on the offering day and the listing day, and there is a significant price reversal on the day following the IPO listing. We also find evidence that the market order imbalance on the pre-offering day and the listing day is lower than on an ordinary day but higher on the day following the listing. Given China’s market capitalization, trading volume, and our sample size, these findings lend strong support for the hypotheses that sizeable IPOs attract investor attention and crowd out the demand for other stocks in the market, and that the market impact of such supply shocks are transitory.
