问题如下:
The following exhibit shows the annual returns for Fund Y.
The geometric mean return for Fund Y is closest to:
选项:
A.14.9% B.15.6% C.19.5%解释:
A is correct. The geometric mean return for Fund Y is found as follows:
Fund Y= [(1 + 0.195) x (1-0.019) × (1 + 0.197) x (1 + 0.350) x (1 + 0.057)](1/5) -1 = 14.9%.
1、前面的括号里计算出来的值是5.779,然后再进行五分之一次方的计算,得出来的数是1.42,再用1.42减1,得出来的是42%呀?
2、是否能用A*H=G平方来计算?
