This paper examines the predictability of corporate bond returns using the transaction-based index data for the period from October 1, 2002 to December 31, 2010. We find evidence of significant serial and cross-serial dependence in daily investment-grade and high-yield bond returns. The serial dependence exhibits a complex nonlinear structure. Both investment-grade and high-yield bond returns can be predicted by past stock market returns in-sample and out-of-sample, and the predictive relation is much stronger between stocks and high-yield bonds. By contrast, there is little evidence that stock returns can be predicted by past bond returns. These findings are robust to various model specifications and test methods, and provide important implications for modeling the term structure of defaultable bonds. Ó 2012 Elsevier B.V.

1. Introduction One of the most enduring issues in finance and economics is the question of whether returns on risky assets are predictable. This important issue has been the focus of an extensive literature on asset prices dating back more than a century. Despite an enormous amount of past efforts, whether future asset price changes can be meaningfully predicted is still a subject of ongoing debates and intensive empirical research (see, for example, Ang and Bekaert, 2007; Campbell and Thompson, 2008; Welch and Goyal, 2008; Rapach et al., 2010; Sekkel, 2011).1 The literature of asset return predictability has focused on the stock market. There is substantial evidence that stock returns are predictable, either by past price changes or economic variables (see Campbell et al., 1997; Ang and Bekaert, 2007; Campbell and Thompson, 2008; Rapach et al., 2010). Recent efforts have been directed to identifying the predictive components of asset returns at different return horizons, evaluating the predictive power of ⇑ Corresponding author.

predictors using more robust tests, and determining how much predictability is compatible with efficiency consistent with risk-based asset pricing models. Notwithstanding extensive research on equity return predictability, there are only a few studies on corporate bond return predictability (see Keim and Stambaugh, 1986; Kwan, 1996; Hotchkiss and Ronen, 2002; Downing et al., 2009) and empirical evidence is inconclusive. Kwan (1996) shows that significant negative contemporaneous correlation exists between returns of individual stocks and yield changes of bonds issued by the same firm, and that stock returns predict future bond yield changes. Unlike Kwan (1996) and Hotchkiss and Ronen (2002) find that...
