The combination of these two perspectives will provide a more comprehensive conclusion about the extent of Chinese market efficiency. The test of price movement shows that all four market has achieved the weak form market efficiency. But the momentum strategy applied in Shanghai and Shenzhen stock market shows a significant loss, suggesting the existence of contrarian effect. This result indicates that the extent of the market efficiency is relatively low compared to Small and Medium Enterprise board and Growth Enterprise Market. In addition, the contrarian effect is significant in all four markets in the bull period around year 2015.
