四、主题:Explaining the relationship between outliers and momentum in corporate bonds: Less bad news is more
五、内容简介:
The debate on whether momentum in corporate bonds is spurious due to random outlier treatments challenges empirical studies. This paper provides an economic rationale for the outlier and momentum relationship, leveraging corporate bonds' asymmetric reaction to information. For both investment-grade and non-investment-grade bonds, the quick diffusion of bad news through negative outliers identifies "bad" losers with short-lived price trends. Trimming negative outliers during the formation period significantly boosts momentum profitability while mitigating crashes and providing hedging against down markets. Conversely, trimming positive outliers weakens momentum by throwing away "good" winners. This asymmetry cannot be explained by illiquidity or down-market optionality.
