问题如下:

 Açor reviews a recent risk tolerance questionnaire completed by Njau, which relates to overall portfolio risk. Açor focuses on the type of capital sufficiency analysis to perform for Njau. To determine the optimal allocation, Açor seeks to ensure that Njau’s charitable pledge can be met and implements a goal- based investing approach. Açor runs a Monte Carlo simulation to determine the probability of success, which is the likelihood that Njau can meet her charitable pledge objective. The simulation results are presented in Exhibit 2.

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.

嗨,努力学习的PZer你好:


  • 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 optimizationà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


同学可以参考基础班P79页:Goal-based Investing Approach
