问题如下:

Based on Exhibit 1, Flusk’s portfolio is expected to experience:

选项:

A.

a minimum daily loss of $1.10 million over the next year.

B.

a loss over one month equal to or exceeding $5.37 million 5% of the time.

C.

an average daily loss of $1.10 million 5% of the time during the next 250 trading days.

解释:

B is correct. VaR is the minimum loss that would be expected a certain percentage of the time over a specified period of time given the assumed market conditions. A 5% VaR is often expressed as its complement—a 95% level of confidence. Therefore, the monthly VaR in Exhibit 1 indicates that $5.37 million is the minimum loss that would be expected to occur over one month 5% of the time. Alternatively, 95% of the time, a loss of more than $5.37 million would not be expected

不是应该是minimum loss吗?为什么答案C是average对呢?

同学你好,根据你的反馈,我认为你理解了选项,但题干要求是选择正确选项,C选项是一个错误选项,所以不选。

分布的尾端是一个范围,是没有均值的。c选项的正确表述应为there is 5% that the loss would be  over $1.1miilion in one day 。希望可以帮到你
