We investigate the association between bond returns and 32 financial statement variables. Our findings show that 17 of the 32 financial statement measures we examined are significantly related to future bond returns. Evidence of inefficiency is more pronounced when institutional investors are less active and when there is more uncertainty about the creditworthiness of the issuer. We contribute to the literature by significantly expanding the number of anomalies analyzed and by providing practitioners with actionable guidance on which trading strategies may be profitable in the bond market.
