问题如下:

Which of Tang’s observations is least likely to be the consequence of Jordan demonstrating loss-aversion bias?

选项:

A.

Observation 1.

B.

Observation 2.

C.

Observation 3.

解释:

C is correct.

Loss aversion by itself may cause a sector concentration; however, a market neutral strategy tends to focus on individual stocks without regard to the sector. The sector exposure would be mitigated with the balancing of the individual long and short positions.

  • Observation 2: The trading volume of the fund has decreased by more than 40 percent during the past year.

  • Observation 3: The portfolio is more concentrated in a few sectors than in the past.

B: 他loss aversion 就将亏损的股票全部持有,好的股票都卖了,trading volume为什么会下降啊?不是应该不变或者上升吗?

C:亏的都留着在,那就是可能集中在某些行业,因为行业风险的原因一亏都亏,所以更集中

C应该是对的的呀 B是错的呀,求解

嗨,努力学习的PZer你好:


1)B: 他loss aversion 就将亏损的股票全部持有,好的股票都卖了,trading volume为什么会下降啊?不是应该不变或者上升吗?

因为案例背景第一段最后一句有交代前提,最近一年,她的基金严重跑输基准,说明现在大部分的持仓都是浮亏的状态

又因为 hold loser,所以交易量相比之前下降了

同学所分析的,好的股票都卖了,是要能从案例背景的句子中分析出来的,但是就案例背景来看,出题人更多想考查的是 hold loser 的场景

2)C:亏的都留着在,那就是可能集中在某些行业,因为行业风险的原因一亏都亏,所以更集中

其实这道题不选 C,并不是因为 Observation 3 的分析结果是 portfolio 没有 more concentrated in a few sectors,也不是从这个角度出发

而是用的排除法,因为题目是问 least likely,所以相比选项 A 和 B,选项 C 的可能性最小,才选的 C

这个选项我之前刚好总结过,包括解题思路及备考建议,请同学先参考一下:https://class.pzacademy.com/qa/88186

如果同学还有疑问,可以追问或者评论,我再回答同学的后续疑问
