The q-factors and expected bond returns

摘要

This study provides new insight into the recent debate on profitability and investment patterns in the cross-section of expected returns. Relying on implied risk premia of U.S. corporate bonds, we document a strong negative relation between exposure to the profitability factor and cost of debt. We do not observe a robust relation between exposure to the investment factor and cost of debt. Our findings are consistent with profitability being a risk factor, but suggest that high profitability implies lower (and not higher) risk. Because the market portfolio consists of all risky assets including corporate bonds, our findings challenge a risk-based explanation for the profitability and investment patterns in stock returns.
