disposition_effect
The disposition effect is the tendency to sell assets that have increased in value (winners) too early while holding onto assets that have decreased in value (losers) too long. Investors are reluctant to realize losses because doing so makes the loss feel real and final, while they are eager to lock in gains to experience the pleasure of a successful trade.
An investor sells a stock that has gained 20% to 'lock in profits' while continuing to hold a stock that has lost 30%, hoping it will 'come back,' even though tax considerations and future prospects may favor the opposite strategy.
A first-time property investor quickly sells a rental apartment that appreciated by 15% after just one year to 'bank the win,' while holding onto a second property that has lost 25% of its value for three more years, convinced the neighborhood will eventually recover.
During a market downturn, a retail trader sells her profitable green-energy shares within days of a modest gain but refuses to exit her losing position in a struggling retailer for months, repeatedly telling herself it is 'just a temporary dip.'

Loss aversion makes realizing a loss psychologically painful - as long as the losing position is held, the loss remains 'on paper' and feels less real. Selling a winner provides the pleasure of a realized gain, reinforcing the behavior.
Evaluate each position based on its future expected return rather than its purchase price. Ask: 'If I held cash instead, would I buy this asset at its current price?' If not, sell regardless of whether it represents a gain or loss.
The disposition effect has been documented in stock markets worldwide, real estate markets (homeowners refuse to sell below their purchase price), and even in experimental settings with no real money at stake.
