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! |
