问题如下:
If the goal is to hedge out all the factor risks and create a zero-beta portfolio, then we can take the opposite positions in each of the factors so that the combined portfolio contains no factor exposures. Is this ture?
选项:
A.True B.False解释:
It is ture就是我觉得BMS和HML项的补偿多多少少在大盘项里已经补偿过了吧,就比如说一个大盘的组合,跟大盘的相关系数是1,再假设一个市场百分之99都是大盘股,那么这个市场组合跟大盘股的相关系数也很高,那么算出来的这个大盘组合的回报率就大于大盘的预期回报率了
