问一道题:NO.PZ2020042003000026 [ FRM II ]

问题如下:

To unwind a large position, which of the following statements is NOT correct?

选项:

A.

If the position is unwound quickly, the trader will face large bid–offer spreads, but the potential loss from the mid-market price moving against the trader is small.

B.

When Deciding how to liquidate a large position over an n-day period, a trader might reasonably wish to minimize VaR after trading costs have been considered

C.

When a position is to be closed out over n days, more than 1/n of the position should be traded on the first day

D.

when unwind a large position over n days, As the VaR confidence level is reduced, the amounts traded per day show more variability.

解释:

考点:对Liquidity Trading Risk的理解

答案:选项D描述错误,因此本题选D

解析:

关于D选项,正确的表述为:As the VaR Confidence level is reduced, the amounts traded per day show less variability.

也就是当Confidence level降低时,每日“最优交易量”之间的差距会变小。

请问这道题d是什么意思?

嗨,努力学习的PZer你好:


因为每日最优交易量其实就是在求最小化LVaR,每日最优交易量和LVaR就是一个函数关系。

LVaR由LC与VaR构成,confidence level降低,z值降低,VaR降低,LVaR降低,每日最优交易量差距就会变小。

在基础班视频section2的unwinding a position optimally老师有详细讲解这部分内容,同学可以再听一下。

嗨,从没放弃的小努力你好:


D的意思是随着confidence level降低,每日“最优交易量”之间的差距会变小。

比如用5天unwind,95的confidence level下,每日最优交易量是48.9,30,14.1,5.1,1.9。

那90%的confidence level下,这5天每日的最优交易量是45,29.1,15.6,7, 3.3。也可以理解成每日最优交易量组成的这个数列的标准差变小了。

为什么confidence level降低,每日最优交易量的差距会变小呢?原理是什么?
