B选项为什么不对?

NO.PZ2018091702000010

问题如下:

Linda is a portfolio manager with excellent record of performance. She owes the success to her team, which is full of experienced experts.  Last year, her fund suffered a severe loss due to economic policy changes, but she believes the investment strategy is still successful.

In a regular meeting, she tells the team the portfolio strategy is still working, and the fund’s return will revert very soon. She will hold underperformed stocks until they cover all the losses.

Which of the following behavior demonstrate Linda’s loss-aversion bias?

选项:

A.

Owing the success to her team.

B.

Her thoughts on portfolio strategy and portfolio performance.

C.

Deciding to hold the stocks until they cover all the losses.

解释:

C is correct.

考点Loss aversion bias的表现

解析Loss aversion bias表现为sell winner, hold loser表现好的股票过早地抛出表现不好的股票持有太久所以C正确

B选项跟C选项不是因果关系吗?以为认为战略是成功的,所以继续持有,试图避免实现损失,B为什么不对?

嗨,爱思考的PZer你好:


1

选项 B 是 Linda 对组合策略和表现的观点

对应案例背景第一段的的最后一句,以及第二段的第一句

从出题人角度出发,是想考查过度自信偏差 overconfidence bias

相当于案例背景中,不同的关键句,反映不同的偏差

2

从备考角度出发,这道题建议把握好选项 C 即可

然后建议再搭配看一下 R1 课后题第 10 题
