同学,上午好。
234类使用Effective duration是Shrewsbury说的,Shrewsbury说的是正确的所以AC不选。B是错的,Sliver说的内容如下:
题干中Silver tells Shrewsbury, “... ... Clients with liability types such as those listed in Exhibit 1 use yield statistics, such as macaulay, modified duration, money durations, and the present value of a basis point (PVBP), when implementing immunization strategies.”
Sliver说1234类(such as those listed in Exhibit 1)用的都是macaulay, modified duration, money durations,PVBP这些。但是只有TypeI 可以用macaulay, modified duration,money duration,PVBP。234类要使用effective duration。
