Regret aversion

NO.PZ2023012803000010

问题如下:

Over the years, Chee regularly surveyed her clients to detect any behavioral biases in their investment decision-making processes.

She determined that her clients routinely exhibited the biases summarized in Exhibit 1 Chee Clients: Behavioral Biases


Client 1 and Client 2:

Rodriquez asks Client 1 and Client 2 to consider two equities, Uno Inc. and Deux Co., which each had purchased for their respective portfolios. The purchase price and current price are shown in Exhibit 2. Neither equity pays dividends.

Exhibit 2 Selected Equity Holdings (in USD)


Determine, assuming Chee’s bias assessments are correct, which action (buy additional shares, take no action, sell) each client will most likely choose for each of the following equities:

i. Uno Inc.

ii. Deux Co.

Justify each response.

Note: Consider each client (Client 1 and Client 2) and each equity independently.



解释:



对于regret aversion来说,

如果已持有,不管股价怎么变都是持有不动对吗?因为怕错过上涨?为什么不能说害怕错过卖出呢?

那如果没持有的话,是不是就是买入?因为怕错过上涨?

嗨,从没放弃的小努力你好:


1)对于regret aversion来说,如果已持有,不管股价怎么变都是持有不动对吗?

是的,因为害怕做了错误的决策而后悔

2)因为怕错过上涨?为什么不能说害怕错过卖出呢?

也可以的,本质都是害怕做了错误的决策

3)那如果没持有的话,是不是就是买入?因为怕错过上涨?

如果没持有,但是题干又描写了其他投资者的行为,那么有可能会买入,形成羊群效应
