Extending Fama–French Factors to Corporate Bond Markets

Abstract

The explanatory power of size, value, profitability, and investment has been extensively studied for equity markets. Yet, the relevance of these factors in global credit markets is less explored, although equities and bonds should be related according to structural credit risk models. In this article, the authors investigate the impact of the four Fama–French factors in the US and European credit space. Although all factors exhibit economically and statistically significant excess returns in the US high-yield market, the authors find mixed evidence for US and European investment-grade markets. Nevertheless, they show that investable multifactor portfolios outperform the corresponding corporate bond benchmarks on a risk-adjusted basis. Finally, their results highlight the impact of company-level characteristics on the joint return dynamics of equities and corporate bonds.
