问题如下:
Which of the following statements is incorrect?
选项:
A.Expected positive exposure (EPE): is defined as the average expected exposure across all time horizons.
Negative exposure: being represented by negative future values. This will obviously represent the exposure from a counterparty’s point of view.
measures such as EE and EPE can capture properly “roll-over risk”.
解释:
答案:D is correct.
解析:注意,本题让选的是错误的一项。A/B/C三个选项描述正确,D选项描述错误。
EE 和 EPE存在缺陷,他们可能会低估短期交易里的Exposure(underestimate exposure for short-dated transactions),并且正确的衡量到Roll-over risk。
为了解决EE和EPE的问题,我们就引入了effective EE and effective EPE
这个答案的意思是EE和EPE到底能不能衡量roll-over risk呢?
