The Investment Performance of Low‐grade Bond Funds
研究低等级债券基金的表现，发现长期回报与高等级债券指数相近，但风险特征不同：低等级债券对利率变化不敏感，对股价变化更敏感。
ABSTRACT This study extends the literature on the pricing of low‐grade bonds by examining the performance of low‐grade bond funds. The findings reveal that over the long run low‐grade bond fund returns are approximately equal to the returns provided by an index of high‐grade bonds. The relative risks of high and low‐grade bonds are more difficult to assess. Because of their shorter durations, low‐grade bonds are less sensitive to movements in interest rates than high‐grade bonds. On the other hand, low‐grade bonds are much more sensitive to changes in stock prices than high‐grade bonds. When adjusted for risk using a simple two‐factor model, the returns on low‐grade bond funds are not statistically different from the returns on high‐grade bonds.
