An analytical derivation of the relation between idiosyncratic volatility and expected stock return
Modelling stock return generating process as a single factor model, we show analytically that the relation between idiosyncratic volatility measured as variance of the residuals and expected stock return in the cross-section may be represented by a parabola that opens to the left and has horizontal axis. This relation is uncovered for stocks of similar volatility and no abnormal return. The sen...
متن کاملIncomplete information , idiosyncratic volatility and stock returns ∗
When investors have incomplete information, expected returns, as measured by an econometrician, deviate from those predicted by standard asset pricing models by including a term that is the product of the stock’s idiosyncratic volatility and the investors’ aggregated forecast errors. If investors are biased this term generates a relation between idiosyncratic volatility and expected stocks retu...
متن کاملIdiosyncratic Volatility of Liquidity and Expected Stock Returns
We show that idiosyncratic liquidity risk is positively priced in the cross-section of stock returns. Our measure of idiosyncratic liquidity volatility is based on a ”market” model for stock liquidity. Idiosyncratic volatility of liquidity is priced in the presence of systematic liquidity risk: the covariance of stock returns with aggregate liquidity, the covariance of stock liquidity with aggr...
متن کاملInformation Systems and Stock Return Volatility
Measuring Information Systems (IS) value has been constantly attracting much attention and debate within the IS research community. Since information systems effects are often difficult to quantify, traditional payoff evaluation methods often yield conflicting results. In this paper we suggest that some information systems can be evaluated on the basis of their effect on stock return volatility...
متن کاملThe Information Content of Idiosyncratic Volatility
Ang, Hodrick, Xing, and Zhang (2006a) show that stocks with high idiosyncratic return volatility tend to have low future returns. This paper further documents that idiosyncratic volatility is inversely related to future earning shocks, and more importantly, that the returnpredictive power of idiosyncratic volatility is induced by its information content about future earnings. We examine various...
