2022-08-09 15:03For an option-free bond, effective duration: a.will be equal to modified duration if the yield curve is absolutely flat. b.measures interest rate risk for both parallel and non-parallel benchmark yield curve shifts. c.is an estimate of the percentage change in bond price given a change in the bond’s yield to maturity. 老師好,能幫忙講解一下這道題嗎為什么只有當yield curve是平行于x軸的時候effective duration才等于modified duration呢?

同學你好,
effective duration和modified duration公式很相似,區(qū)別就在于收益率的變動率這里,因為YTM是一條水平線,那么curve也是水平的時候,此時兩者是相同的。
