问题如下:
Which of the following may be controlled by an investor?
选项:
A.Risk
B.Raw returns
C.Risk-adjusted returns
解释:
A is correct.
Many decision makers focus on return, which is not something that is easily controlled, as opposed to risk, or exposure to risk, which may actually be managed or controlled.
请问C为什么不对?比如夏普指数,就是risk-adjusted rate,那为什么investor控制不了夏普指数呢?
