问一道题:NO.PZ2018091702000006

问题如下:

Jacob is a famous scientist and has a portfolio currently worth $10 million. He said to his portfolio manager, - I can bear the risk of losing at most 10% of my portfolio every year. I studied some basic financial theories at home, so if my portfolio follows the equation: Expected return -2.33×standard deviation≥10%, you are free to choose any asset classes.-

Which of the following strategy should the portfolio manager take to help Jacob manage his account? The manager should

选项:

A.

construct a mean-variance efficient portfolio.

B.

divide Jacob's portfolio into layers to meet his goals.

C.

sell Jacob's stocks if his portfolio increases more than 10%.

解释:

A is correct.

考点传统金融学VS行为金融学

解析这个客户在表达自己的投资策略时使用了Expected returnstandard deviation两个变量,所以客户更喜欢均值方差最优化的有效投资组合,这与传统金融学理念一致,选A

没有证据显示他有多个投资目标题干也没有说他在股票上涨时会如何处理

Expected return -2.33×standard deviation≥–10%想问下这个是怎么解读的。

嗨,爱思考的PZer你好:


对应的就是解析里的那句解读: 这个客户在表达自己的投资策略时使用了Expected return和standard deviation两个变量。

我们不用解读它这个expected return和standard deviation具体的大小,它传递出的信息只是说明了客户使用了传统金融的决策方法,即 mean-variance efficient portfolio.
