Assuming that the yield falls by 90 basis points, what's the percentage of the price change of a bond with a modified duration of 9.6?
选项:
A.10.67%.
B.-8.64%.
C.8.64%.
解释:
C is correct.
Correct answer:
(-9.6)x (-0.90%)=8.64%
Incorrect answer:
9.6x (-0.90%)= -8.64%
(-9.6)/ (-0.90%)=10.67%
请问为什么直接乘就可以?
