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.【资料下载】[融跃财经]FRM一级ya题-pdf版
