问一道题:NO.PZ2018110601000019 [ CFA III ]

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。

B选项中的top level是什么意思?

嗨,努力学习的PZer你好:


top-level是鸟瞰、站在高层的角度看待问题。 识别所有风险并且分配风险,站在的就是一个高层的角度,所以B选项的描述不准确。

那应该是什么呢

嗨,从没放弃的小努力你好:


这道题答案应该是C,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。

B的描述错了,基础班讲义138页risk budgeting定义:The risk budget identifies the total amount of risk and allocates the risk to a portfolio’s constituent parts。所以说,risk budget 是top-level的,并且它的过程就是识别所有分别并且分配风险。错在“rather than”。

虽然现在很辛苦,但努力过的感觉真的很好,加油!
