Disposition Effect in Investing: Why Investors Sell Winners and Keep Losers
A research brief on the disposition effect and how it distorts sell decisions, holding periods, and portfolio outcomes.

FAQ
How can I tell if the disposition effect is affecting me?
Look for a pattern of short holding periods in winners and long holding periods in losers without stronger evidence supporting the difference.
What is the best practical countermeasure?
Use the same review checklist for both winning and losing positions so emotion does not change the standard.
Is this bias common even among experienced investors?
Yes. Experience helps only when it is paired with structured review and clear exit policies.
Replace bias with one consistent sell standard
Use the same checklist on one winner and one loser this week and compare whether your reasoning holds up equally.
