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.
1、老师能帮忙区分下这三个duration嘛
2、看了一些答案的解析有点混淆了,single lia和multiple的immunization的条件,我怎么记得最后都是直接asstBVP大于等于lia的BVP,然后asset的convexity大于lia的、但要尽量小?
