This paper studies the cross-sectional risk-return trade-off in the stock market. A fundamental principle in finance is the positive relation between risk and expected return, whereas recent empirical evidence suggests the opposite. Using several intuitive risk measures, we show that the...

This study investigates the impact of return extrapolation on risk-return trade-offs in both the aggregate time series and the cross section of stocks. We find that the relation between the market’s expected return and expected variance is positive during periods with a low degree of...

Short selling, as compared to purchasing, faces greater risks and other potential impediments. This arbitrage asymmetry explains the negative relation between idiosyncratic volatility (IVOL) and average return. The IVOL effect is negative among overpriced stocks but positive among underpriced...

Uncertainty has qualitatively different implications than risk in studying executive incentives. We study the interplay between profitability uncertainty and moral hazard, where profitability is multiplicative with managerial effort. Investors who face greater uncertainty desire faster learning,...
