问一道题:NO.PZ2020033001000086

问题如下:

Anna, FRM, an analyst in Zack Corporation, is determining the value at risk (VaR) for the corporation's profit/loss distribution. The distribution is assumed to be normally distributed with an annual mean of $2 million and a standard deviation of $0.5 million. What is the VaR with a 99% confidence level if a parametric approach is applied?

选项:

A.

$0.01 million.

B.

$0.33 million.

C.

$1.33 million.

D.

$2.33 million.

解释:

B is correct.

考点:Parametric Estimation Approaches

解析:

The population mean and standard deviations are unknown; therefore, the standard normal z-value of 2.33 is used for a 99% confidence level.

VaR(1%) = -2.0 million + ($1 million)(2.33) = -2.0 million + 2.33 million =0.33 million.

题干和答案有偏差,题干的标准差是0.5,答案应该是0.835。答案里的标准差是1,需要统一一下题干和答案。
