A client sells a stock immediately after it falls 5% from her purchase price even though fundamentals are unchanged, but she holds another stock that has fallen 30% hoping it will 'come back to my cost'. Which bias best explains her reluctance to sell the second stock?

The reluctance to sell the stock that has fallen 30% is best explained by loss aversion leading to the disposition effect: investors avoid realising losses and hold losers hoping to recover cost, while they quickly sell gainers or small decliners.

  2. BHome bias
  3. CRecency bias in forecasting
  4. DRepresentativeness bias

Explanation

The disposition effect is the tendency to sell winners early and hold losers too long to avoid realising a loss, which stems from loss aversion. Here the client anchors on her purchase cost and avoids booking a loss. Home bias concerns preference for domestic assets, which is not the issue described.
