- Abstract
This article conducts research on the daily closing prices and yields of the Shanghai Composite Index and the Shenzhen Composite Index from January 2, 2014 to January 2, 2020. Based on the random walk assumption, the unit root test, the run test and the autocorrelation test were used to examine the efficiency of Shanghai Stock Exchange and Shenzhen Stock Exchange respectively. According to the findings, both Shanghai and Shenzhen stock markets have reached weakform market efficiency. Because the three tests cannot prove whether there is a relationship between the Shanghai and Shenzhen stock markets, this article uses the Johansen cointegration test and the Granger causal test to determine whether the Shanghai and Shenzhen stock markets are joint weak-form market efficiency. The results reveal that there is no cointegration relation between the closing prices of Shanghai and Shenzhen Composite Index, but the daily yield of Shanghai and Shenzhen Composite Index can predict each other to some extent. Therefore, it is deduced that Shanghai and Shenzhen stock markets has not attained the joint weak-form market efficiency.
