Do Foreign Institutional Investors Destabilize China’s A-Share Markets?

This paper investigates the eect of foreign institutional investors on the sta- bility of Chinese stock markets. Previous literature views this investor group as destabilizing feedback traders. We use the abolition of ownership restrictions on A shares as a natural experiment. There is strong evidence that foreign in- stitutions have a stabilizing eect on Chinese stock markets and contribute to market eciency. This nding is robust across exchanges, sample periods, size quintiles and alternative model specications. By contrast, domestic investors appear to engage in positive feedback trading. Our results have important implications for market regulation.
