Abstract:

It is a basic inference of capital asset pricing model (CAPM) that there is a positive relationship between systemic risk and yield, but some empirical studies proved that the relations are not significantly positive, which may result from using historical returns as unbiased estimates of the expected yield. According to intertemporal capital asset pricing model (ICAPM), this paper carries out an empirical test by using the ratio of stock's returns and price (E/P ratio) as a proxy for the expected yield, and testifies the positive correlation in Chinese stock market. On this basis, considering the impact of investors' heterogeneous belief on the relationship between risk and return, the traders are divided into three categories in accordance with investment characteristic in the framework of behavioral asset pricing. The empirical results again show that there exist both a significantly positive relation between risk and return and three kinds of heterogeneous traders, which provide new evidence for behavioral financial theories.

Key words: intertemporal risk-return tradeoff, E/P ratio, heterogeneous belief, behavioral asset pricing
