We explore the value premium in the Chinese stock market and how to exploit it using a new investor sentiment index. We extensively discuss the performance of BM, CFP, EP and SP factors in China. Consistent with the experience of other countries, BM generates more of a value premium in small cap performance, while EP generates more of a value premium in large cap stocks in the Chinese stock market. First, we construct a novel value factor based on BM, EP and SP. We obtain the loading weights of each value indicator in each market value by partial least squares. The novel value factor outperformed all other value factors. Second, we explore the relationship between value premium and investor sentiment. Different from evidence from most developed countries, the value stocks perform better than growth stocks in the bull market in China. Our evidence suggests investing in value stocks can get more profit when market sentiment is low.
