这道例题,对于interaction的解释是the fund sponsor over weighted a manger who outperformed his benchmark.
然后对于interaction+selection的解释是 the decision to overweight value equities added to portfolio return.对于这一点还算比较好理解,反正对于基金经理的选择就是两个加一起。但是前面那个对于interaction的解释怎么理解。
就比如这道题现在出成问答题,让你计算一下the fund sponsor over weighted a manger who outperformed his benchmark.是多少,就不知道该算哪一部分了。
