BETA IN THE CHINESE MARKETS: WANTED DEAD OR ALIVEDownload This Article
Bernard Bollen, Mike Dempsey, Larry Li
The capital asset pricing model (CAPM) states that higher beta stocks are priced to deliver higher returns. Even when this is not the case, however, goods and services that are inherently more (less) sensitive to the economy are expected to display stable higher (lower) betas. By this we mean, that when the economy rises, the underlying stocks of those firms that benefit the most are those that we expect to raise the most, and thereby have higher betas. And, in reverse, for economic downturns. In the present paper, we apply both considerations (higher beta stocks have higher average performances, and higher beta identifies those firms that respond most sensitively to the economy) to the Chinese markets. Our essential finding is that the level of stability of beta found in U.S. markets is not replicated in Chinese markets. Over the period of 1997-2006, the betas of Chinese stocks tend to revert to the mean (beta = 1). Not surprisingly, Chinese betas provide only weak value as indicators of portfolio exposure to subsequent market movements.
