问题如下：
Jeffery, a fund manager, is talking with three new clients about their previous investment style.
Leonard says: If a stock in my portfolio is significantly underperforming, I tend to hold it until the loss is covered.
Morgen says: Last year, the stock market was in poor situation. The trading volume of my portfolio was less 35% than normal year.
Nick says: I work in the banking industry. Therefore, my portfolio is made up of three stocks in finance sector.
Whose behavior is least likely to be the consequence of loss-aversion bias?
选项：
A.Leonard
B.Morgen
C.Nick
解释：
C is correct.
考点：Loss aversion bias
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，正因为持有太久所以交易量减少， A和B都是对的。C主要是投资自己熟悉的行业，不是Loss aversion bias的典型后果。
老师，我记得之前有道题的解析是：
有一个人在股票上涨25%或者下跌10%的时候卖出，这也是LOSS AVERSION。
但是上涨一点点的时候就卖，下跌很多的时候持有，这也是LOSS AVERSION。
？？？？？？
到底啥时候是LOSS AVERSION？？
