问题如下:
Which of the following statement regarding risk budgeting is most appropriate?
选项:
A.An optimal risk budgeting is to minimize the total risk.
B.Risk budgeting is on top-level rather than allocates the risk to a portfolio’s constituent parts.
C.An asset allocation is optimal when the ratio of excess return to marginal contribution to risk is the same for all assets.
解释:
C is correct.
考点:risk budgeting
解析:risk budgeting的目标是最大化每承担一单位风险所获得的收益,而不是最小化风险,A错。risk budgeting的过程是识别所有风险并且分配风险,B错。C是risk budgeting的结论,当每个资产类型的excess return/MCTR都相同时,资产配置是最优的。
我知道选项C是一个结论,但不理解,是否可以解释一下
为什么 资产配置是optimal when the ratio of excess return to marginal contribution to risk is the same for all assets.
