选项b

* 问题详情,请 查看题干

NO.PZ201512181000007202

问题如下:

In Statement 2, Kynnersley implies that the portfolio:

选项:

A.

is at risk of losing $4,500 each trading day

B.

value is expected to decline by $90,000 or more once in 20 trading days.

C.

has a 5% chance of falling in value by a maximum of $90,000 on a single trading day.

解释:

B is correct.

Value at risk is the minimum loss that would be expected a certain percentage of the time over a certain period of time. Statement 2 implies that there is a 5% chance the portfolio will fall in value by $90,000 (= $6,000,000 ×1.5%) or more in a single day. If VaR is measured on a daily basis and a typical month has 20–22 business days, then 5% of the days equates to about 1 day per month or once in 20 trading days.

能翻译一下选项b吗,谢谢老师

嗨,爱思考的PZer你好:


B选项的就是在换着角度来描述statement 2里给出的5%的VaR。其中:

$90,000对应statement 2中“1.5% of portfolio value”。由于portfolio value为$6 million,所以1.5%就是$9,000;

“...to decline by $90,000 or more”意为最小损失为9,000;

“...more once in 20 trading days”就是5%。

所以B选项就是在说5%的情况下,最小损失是$9,000。和statement 2中描述的5% VaR完全一致。


提问时请具体说明需要“翻译”的地方,如思维在哪里卡住了,哪个描述不理解,或者和答案解析对不上。单纯的英译中是没有意义的。
