想法可能有点绕

问题如下:

One interpretation of an upward sloping yield curve is that the returns to short-dated bonds are:

选项:

A.

uncorrelated with bad times.

B.

more positively correlated with bad times than are returns to long-dated bonds.

C.

more negatively correlated with bad times than are returns to long-dated bonds.

解释:

One interpretation of an upward sloping yield curve is that returns to short-dated bonds are more negatively correlated with bad times than are returns to long-dated bonds. This interpretation is based on the notion that investors are willing to pay a premium and accept a lower return for short-dated bonds if they believe that long-dated bonds are not a good hedge against economic “bad times”.

能明白经济越不好,短端的收益率越低,但是如何区分到底是正相关还是负相关呢

嗨,爱思考的PZer你好:


经济差时,投资者倾向于买流动性更好的短期债券避险,所以经济差时对短期债券的需求更多,引发短债价格上涨的更多。

价格上涨一方面导致短期的yield下降的更多,使得yield curve向上倾斜。

另一方面,短债的价格上涨意味着持有短债的return会在经济差时上升的更多。经济差对应return反而高,故短债的return是“more negatively correlated with bad times”。
