NO.PZ2015121801000131 问题如下 Returns on asset classes are best scribebeing a function of: A.the failure of arbitrage. B.exposure to the iosyncratic risks of those asset classes. C.exposure to sets of systematic factors relevant to those asset classes. is correct.Strategic asset allocation pen on severprinciples. statein the reang, \"One principle is tha portfolio’s systematic risk accounts for most of its change in value over the long run.\" A seconprinciple is that, \"the returns to groups of like assets… prectably refleexposures to certain sets of systematic factors.\" This latter principle establishes threturns on asset classes primarily reflethe systematic risks of the classes. 我的理解既然做portfolio,不同的资产类别就肯定是分散了非系统性风险,那风险就只剩下系统性风险,系统性风险的因素,和收益率之间建立函数?是不是就是CAPM公式?B的iosyncrati我查字典是不寻常的特征的,也就是个股的风险,那么是可以被分散掉的。A就是凑数的吧?这套题这么理解对吗?看完答案之后还是觉得懵的,不明白说的到底是啥意思。
这道题考的是什么呢?没明白
老师,什么是isyncratic risk?还有,题目有两个部分我都翻译不清楚,return on “asset classes”?怎么理解?being a function of 是指的是 下面哪个的“函数” 的意思吗?
ROA 为什么是测量系统性风险的?请问是怎样看出来的?
