對于備考FRM的考生來說什么是重要的,那當然是做大量的練習題啦!尤其是近幾年的FRM真題練習,下文是列舉的相關真題解析,備考的你看過來!
Which of the following is a true statement about expected shortfall (ES)?
A) ES is a coherent spectral measure which gives equal weight to the tail quantiles
B) ES is a coherent spectral measure which gives increasingly greater weight to higher tail quantiles
C) ES is a coherent spectral measure but gives decreasingly less weight to higher tail quantiles
D) ES is coherent, VaR is not coherent, and neither are spectral measures
答案:A
解析:ES is a coherent spectral measure which gives equal weight to the tail quantiles. The general class is spectral measures, which contain a weighting function. Both ES and VaR are special cases of a spectral measure (the spectral function generalized both ES & VaR). Spectral measures are coherent under conditions that are met by ES but not by VaR; “Spectral” is associated with, but does not necessarily imply, coherence.【資料下載】[融躍財經]FRM一級ya題-pdf版
