97。5%的es不是等于95%的var吗

NO.PZ2018122701000007

问题如下:

A mutual fund has USD 50 billion in assets. The risk manager computes the daily VaR at various confidence levels as follows:

What is the closest estimate of the daily expected shortfall at the 97.5% confidence level?

选项:

A.

USD 821 million

B.

USD 895 million

C.

USD 919 million

D.

USD 1023 million

解释:

D is correct.

考点 Expected Shortfall

解析 An estimate of the expected shortfall can be obtained by taking the average of the VaRs for the various confidence levels that are greater than 97.5%.This leads to an estimate of USD 1,023,000,000.

嗨,爱思考的PZer你好:


你说的情况应该是是在尾部风险平均分摊的情况下,95%的ES等于97.5%的var。

单这题尾部的风险不是均匀分布的,所以要按ES的定义进行平均数计算。
