问一道题:NO.PZ2018091701000038

问题如下:

Analysts collected some market data to find maximum Sharpe ratio of manager, based on his analysis, market’s expected annual return is 7%, return standard deviation is 24%, Sharpe ratio is 0.41. Universe fund has active return 6% and active risk 12%. Please calculate the maximum Sharpe ratio:

选项:

A.

0.33

B.

0.65

C.

0.42

解释:

B is correct.

考点考察公式 SR2p=SR2B+IR2

解析第一步我们需要先根据已知条件计算出基金的information ratio: IR=6%/12%=0.5

第二步代入公式

SR2p=SR2B+IR2=0.412+0.52=0.42

第三步开根号0.42得到0.65

老师好 是否问max SR 的时候 用的都是这个总SR 平方的公式? 谢谢。
