没有理解为什么又mental accouting bias

NO.PZ2018091702000039

问题如下:

Owen and Yang meet with Callie Steven, an upper level executive with AutoPay, a small but fast growing privately held company. She has been employed with AutoPay for more than 15 years and as a result, her holdings in AutoPay are estimated to be more than 30% of her total portfolio. She believes that over the next several years AutoPay will put together an initial public offering, resulting in a huge windfall. She states that she has a significant portion of her portfolio in short-term bonds and money market funds to offset the risk of her AutoPay shares. Owen points out to Steven that her current portfolio is subject to mental accounting, is not constructed in layers, and does not take into consideration covariance between assets.

Is Owen’s comment regarding Steven’s current portfolio correct?

选项:

A.

No, he is incorrect with regard to portfolio construction 

B.

Yes

C.

No, he incorrect with regard to covariance between assets

解释:

A is correct.

Owen’s comment regarding Steven’s current portfolio construction is not correct. Her current portfolio is subject to mental accounting, has been constructed in layers and does not take into consideration covariance between assets.

嗨,努力学习的PZer你好:


因为 mental accounting bias 的结果,是投资者的投资组合,会按照「资金来源」或者「资金用途」分类

题干已经表述,客户的组合包含三类产品:AutoPay 的股票、短期债券 short-term bond、货币市场基金 short-term bond,可以继续分析不同金融产品的特点

客户持有后两类产品的目的,是为了抵消股票的风险 "to offset the risk",所以可以认为是从「资金用途」的角度构建组合
