Which of the three managers most likely displayed the disposition effect bias?
- Manager Y
- Manager X
- Manager Z
Solution
A is correct. The disposition effect relates to the behavioral bias in which investors tend to avoid realizing losses but, rather, seek to realize gains. Manager Y has displayed this bias.
B is incorrect. Manager X’s behavior of reacting slow to changes is consistent with conservatism.
C is incorrect. Over-reacting, including a dislike for losses more than liking comparable gains, displayed by Manager Z is reflective of a behavioral bias called loss aversion.
