    Summary: 近幾年來,公司特有風險在解釋股價報酬中所扮演的角色受到越來越多的注意。當投資人無法持有一個市場投資組合時,此時公司特有風險需要給予理性投資人相對的補償。本文主要檢驗公司特有風險與橫斷面股價報酬之間的關係。研究採取Xu and Malkiel(2003)直接分解法,其可以使用模型的殘差項來估計出公司特有風險,藉此來研究公司特有風險的特性。本研究採用日股價報酬資料做為樣本來估計公司特有風險變數,觀察公司特有風險是否對於股價報酬具有解釋能力。研究期間取自1986年7月至2007年6月之股票月內交易日,共計252個月的資料。在使用Fama and MacBeth (1973)迴歸方法將公司特有風險與股票超額報酬做迴歸分析之後,發現其在解釋股票超額報酬上,具有顯著的正向關係。本研究發現與Spiegel and Wang(2005)以及Fu(2009)的研究結果一致。 The roles played by idiosyncratic risk in determining stock returns have recently received a great deal of attention. If some investors can’t hold the market portfolio, the idiosyncratic risk could be priced to compensate rational investors for an inability to hold the market portfolio.This paper examines the cross-sectional relation between idiosyncratic volatility and expected stock returns. I use Xu and Malkiel (2003) the direct decomposition method, it could be simply to estimate idiosyncratic volatility using residuals from a factor model. And I can use it to observe the characteristics of idiosyncratic risk. In this study, I use within-month daily data to calculate idiosyncratic volatility based on market model. The period covered in this study is from July 1986 to June 2007.Use Fama and MacBeth (1973) regression model, I find that idiosyncratic volatility is useful in explaining cross- sectional expected returns. I find a significant positive relation between idiosyncratic volatility and the cross-sectional expected returns. The study result is consist with Spiegel and Wang (2005) and Fu (2009).
