问题如下:

Açor’s portfolio allocation for Njau is most likely optimized on the basis of:

选项:

A.

a stated maximum level of volatility.

B.

total portfolio mean–variance efficiency.

C.

the results of the risk tolerance questionnaire.

解释:

A is correct. Açor uses the goal- based investing approach by allocating with a focus on Njau’s charitable pledge to Udhamini. With this method, she seeks to optimize Njau’s portfolio so that the pledge goal has a high probability of being met. Açor will set aside a required amount of funds to invest, and a mean–variance optimization will be run specifically for that portion of Njau’s portfolio. The funds will be invested to a stated maximum level of volatility to meet the charitable need.

看完题目本身并没有马上发现考点是 goal-based, 这个题的解题逻辑是什么?

题眼就在于题干中提到Acor用的是goal-based investing approach, 所以我们要分层考虑每一个goal,也就是在每一个goal内,用mean-variance optimization,那么B一定是错的,因为说的是total portfolio mean-variance efficiency。

在每一个goal内使用mean-variance optimization:波动越大收益越大,那么可以在投资者可接受范围内挑一个最大风险的allocation以便于获得最大化的收益去实现charitable need
