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%.
计算几何平均数可以用计算器吗?
