Abstract:
This paper examines the daily stock price behavior of the 175 individual stocks traded on the Shanghai Securities Exchange for the period of August 1992 through August 1995. We find that stock prices on the exchange tend to move in step with each other. We argue that the market does not appear to efficiently allocate capital resources to their best use. In addition, we find that stock prices on the exchange mostly follow a random walk – serial correlations of stock prices are mostly statistically insignificant. The paper concludes with some policy suggestions to make the market more efficient.
