问题如下:
Which duration measure should be matched when implementing Strategy 2?
选项:
A. Key rate
B. Modified
C. Macaulay
解释:
C is correct.
An investor having an investment horizon equal to the bond’s Macaulay duration is effectively protected, or immunized, from the first change in interest rates, because price and coupon reinvestment effects offset for either higher or lower rates.
如题。不懂modified和Macauley的区别。是因为前者只是近似,不够精确吗?
