1. The optimal weights of the allocations to various fund managers ( of a firm ) do not necessarily have to sum to one . 请问:为什么这个表述是正确的呢?投资人在向基金经理或者基金公司分配资金的时候,不应该是使得每一位(个)基金经理(基金公司)的权重想加等于100%么? 2. The benchmark portfolio cannot be assigned any weight under the optimal allocation scheme across active fund managers of a firm . 请问:为什么这个表述不正确呢?主动管理的投资经理的最优投资组合中也会有一部分权重去投大盘么?
