We examine the trading behavior of Chinese domestic investors after they were given access to the B-share market in 2001. Surprisingly, we find that only 2% of investors began buying B shares. Even among these 2%, investors were less likely to buy B shares if they had more experience in the A-share market, and vice-versa. Thus, prior market experience limits the extent to which investors respond to A/B-share premiums and liquidity and lowers their performance. Our findings cannot be explained by government intervention, investor heterogeneity, foreign currency constraint, A/B-share liquidity or speculation differentials, or information advantage.

We investigate the long-term effects of S&P 500 index additions and deletions on a sample of stocks from 1962 to 2003 and find a significant long-term price increase for both added and deleted stocks, with deleted stocks outperforming added stocks. The long-term price increase for added stocks can be attributed to increases in institutional ownership, liquidity, and analyst coverage, and a decrease in the shadow cost in the long-term. However, while deletion has no significant effect on analyst coverage and shadow cost, we find a rebound in the institutional ownership and liquidity of deleted stocks. The difference in the long-term price increase of added and deleted stocks can be explained by analyst coverage and operating performance.
