The effect of stock index composition changes is one of the important subjects in the field of behavioral finance. With the rapid development of Chinese equity market, stock index is playing an increasingly important part. Chinese equity market, on the other hand, is still at emerging stage, the stock index composition changes may have the different effect from that of the developed countries. However,the correlative study in China is far from enough. This paper investigates the CSI 300 which is the most influential stock index in China to find out the the effect of stock index composition changes in both short term and long term.In the short term, the study focuses on the price and volume. The empirical results show that there is a positive abnormal returns and increasing trading volume of added firms, while a negative abnormal returns and slightly increasing trading volume of deleted firms. However, compared with empirical results abroad, short-term effects associated with the change of the CSI 300 index list is not very obvious, which may be accounted for too little institutional investors in the Chinese stock market.In the long term, this paper firstly studies the long-term stock price performance of the index adjustment. For additions, cumulative return after index adjustment is better than that of the CSI 300 index, but is worse than the performance before the adjustment, while the deletions performance is opposite. Secondly, number of shareholders, institutional investors and stock price volatility are analyzed. There is a significant increase in the number of shareholders of added firms and a decline for deleted firms, but this factor has little influence for abnormal stock price returns. Similarly, for additions, institutional investors increases and volatility reduces, deletions are opposite. Abnormal stock price returns are significantly affected by the number of institutional investors and volatility. In addition, the company size is also a significant factor affecting the abnormal returns.參考文獻 Blume, M., & Edelen, R. (2002). On Replicating the S&P 500 Index. Rodney L.
