问题如下：
Blake’s portfolio would most likely indicate which behavioral bias?
选项：
A.Home bias.
B.Loss aversion.
C.Investing in the familiar.
解释：
B is correct.
Loss aversion is a bias in which people tend to strongly prefer avoiding losses as opposed to achieving gains. The disposition effect, which includes an emotional bias to loss aversion, will encourage investors to hold on to losers, causing an inefficient and gradual adjustment to deterioration in fundamental value. On several occasions, Blake has found herself holding positions with sizable losses, and she has been reluctant to sell when a security declines. This suggests that Blake may exhibit loss aversion bias.
