NO.PZ2020042003000026

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。

看了那么多解释,也不明白答疑老师在说什么

嗨,从没放弃的小努力你好:


这道题说的是大量的清仓,假如清仓的时间短,bid-ask spread比较大,但是mid price不变;如果清仓时间长,不会占用dealer太多资源,bid-ask spread比较小,但是dealer发现市场一直有人卖,mid price会下降。

 

所以存在二者之间的trade off,需要确定最优清仓时间,最小化LVaR。

 

LVaR=VaR+Liquidity Cost也就是要最小化VaR和LC这两项。

 

confidence level是跟VaR相关的,confidence level降低,每天交易量的波动会变小。这个结果是可以计算出来的,上课的时候课件有示例展示,但是计算过程太复杂,考试也不可能去考,所以只需要理解概念记住结论即可。
