问题如下:
In the Sortino ratio, is performance compared to the performance of a risk-free asset or a client-designated benchmark?
选项:
解释:
The Sortino ratio compares a portfolio’s performance to that of a client-designated benchmark which is a minimum return that the client specifies
Sortino比率将投资组合的表现与客户指定的基准(客户指定的最小回报)进行比较
讲义这页最后一句写:T may be set to the risk-free rate or another hurdle rate。
所以我认为这题应该是risk-free asset 和client-designated benchmark都可以。我这是哪里理解错了?
