This paper provides a time-series and cross-sectional investigation of the conditional and unconditional capital asset pricing model (CAPM). The unconditional CAPM fails, but the conditional CAPM with dynamic conditional correlations (DCC) succeeds in generating a significantly positive...

Motivated by existing evidence of a preference among investors for assets with lottery-like payoffs and that many investors are poorly diversified, we investigate the significance of extreme positive returns in the cross-sectional pricing of stocks. Portfolio-level analyses and firm-level...

This paper examines the intertemporal relation between expected return and risk for 30 stocks in the Dow Jones Industrial Average. The mean-reverting dynamic conditional correlation model of Engle (2002) is used to estimate a stock s conditional covariance with the market and test whetherthe...

Using equity returns for financial institutions we estimate both catastrophic and operational risk measures over the period 1973-2003. We find evidence of cyclical components in both the catastrophic andoperational risk measures obtained from the Generalized Pareto Distribution and the Skewed...

We introduce a new, hybrid measure of stock return tail covariance risk, motivated by the under-diversified portfolio holdings of individual investors, and investigate its cross-sectional predictive power. Our key innovation is that this covariance is measured across the left tail states of the...
