The Performance and Long-Run Characteristics of the Chinese IPO Market

We study the short-run and long-run performance of Chinese privatization initial public offerings (PIPOs), using data for 340 and 409 new issues on the Shanghai and Shenzhen Stock Exchanges respectively, from 1 January 1996 through 31 December 1997. The average market-adjusted initial return is found to be 127.31%, and the initial returns on both stock exchanges are not significantly different from each other. The average market-adjusted buy and hold return over the three years after listing is 10.26%, which is significantly different from zero at the 1% level. We then use cross-sectional analysis to explain the long-run supernormal performance of Chinese PIPOs, and find that government ownership, the offering size and the feature of belonging to a high-tech industry are the main determinants of the long-run performance. In addition, firms that perform better in the long-run tend to make more Seasoned Equity Offerings (SEOs), and the underpricing of IPOs is negatively related to their long-run performance.
