Abstract: There is evidence that investors have a preference for stocks with large price variation rather than stocks with flat price variation. Whether such an investment preference causes the idiosyncratic volatility puzzle? In this paper, the existence of the idiosyncratic volatility puzzle in China stock market is firstly examined. Then, portfolio analyses and Fama-MacBeth cross-sectional regression analyses both show that, the range of prices can explain to some extent, but not fully explain the idiosyncratic volatility puzzle. Cross-sectional regression results show that, under the joint effect of the range of prices, the maximum daily return and turnover, the negative relation between the idiosyncratic volatility and expected stock returns is no longer statistically significant. Thus, the investment preference for some special stocks may be the main cause to produce the idiosyncratic volatility puzzle.

Key words: asset pricing, idiosyncratic risk, investment preference, range of prices
