In the past decades, ambiguity in the stock market has been widely studied theoretically and experimentally. Most existing studies focus on foreign financial markets, such as American stock market. However, there are essential differences between Chinese stock market and others stock market, such as its participants and trading mechanisms. Therefore, it is necessary to study the relation of ambiguity, risk and expected return in China's stock market. This study analyzes CSI 300 index data for January 2006 to February 2020 to investigate the relationships between ambiguity, risk, and expected returns in China’s stock market. We apply empirical methods to measure the degree of ambiguity and assess attitudes toward ambiguity from the China's market data, the results indicate that: (1) the degree of ambiguity increases with the expected return; (2) when risk and ambiguity are introduced simultaneously, the expected return of China's stock market is significant negative; and (3) in addition, we also prove that the investors’ level of aversion to or preference for ambiguity, which depends on the expected probability of favorable returns. In sum, our results not only clarify ambiguity and risk regarding expected returns but also provide the theoretical and practical implications for the problem of asset prices in China's stock market.
