The well‐documented negative relationship between idiosyncratic volatility and stock returns is puzzling if investors are risk‐averse. However, under prospect theory, while investors are risk‐averse in the domain of gains, they exhibit risk‐seeking behavior in the domain of losses. Consistent with risk‐seeking investors’ preference for high‐volatility stocks in the loss domain, we find that the negative relationship between idiosyncratic volatility and stock returns is concentrated in stocks with unrealized capital losses, but is nonexistent in stocks with unrealized capital gains. This finding is robust to control for short‐term return reversals and maximum daily return, among other variables.

Purpose The purpose of this paper is to examine the combined performance of momentum and a gross profitability-based strategy. The motivation stems from the strong performance of momentum on the short side and profitability on the long side, suggesting a potentially superior combined strategy. Gross profitability is also a measure of firm quality, so that another motivation is to contribute to a growing literature on factor-based investing that includes momentum and quality as potential factors. Design/methodology/approach The empirical approach employed in the paper is standard in the asset pricing literature. The firms are sorted into portfolios based on profitability and momentum, and the combined performance is studied through independent double sorting. Both value-weighted and equally weighted returns are reported in case of key empirical results. Findings The combined strategy results in superior performance. Specifically, the strategy produces results 2.75 greater than the momentum strategy, and about four times as high as the profitability strategy. The strategy also has much higher Sharpe ratio that improves further when combined with size and value strategies. Research limitations/implications The research has significant implications for academics and practitioners alike. A new investment strategy that has not been explored in the literature is presented. The superior performance of the strategy presents a challenge for the market efficiency, and would be of interest to academics and practitioners working in the area of investment management. Practical implications There has been a growing interest in multi-factor investing in recent years. The paper documents that superior performance is achieved by combining two of the popular factors, namely profitability and momentum. Originality/value The research is the first to study the combined performance of profitability and momentum, and provide evidence on the superiority of the combined strategy.
