[请问胡老师]option-free bond's price sensitivity

怕漏掉, 还是重新启个帖子

---------------------------------------------------------------------

is an option-free bond's price sensitivity postively correlated with

bond's coupon rate?  market interest rate?

----------------------------------------------------------------------

这题的答案说option-free bond's price sensitivity is negatively related to both rates

我觉得market interest rate 与 bond's price 负相关没问题, 但coupon rate 应该是正相关呀?coupon 越高债券价格当然应该更高。

如果用Duration 公式来判断也是这样:  percentage change of bond price = - Duration * Yield change

coupon rate 与 duration 是负相关的,再加上前面的负号

那么coupon rate 与 价格就是正相关。

(我上面的理解有问题么?)

谢谢老师!
