Investors’ 10 Most Common Behavioral Biases | Above the Market

Investors’ 10 Most Common Behavioral Biases | Above the Market: Loss Aversion. We are highly loss averse. Empirical estimates find that losses are felt between two and two-and-a-half as strongly as gains. Thus the disutility of losing $100 is at least twice the utility of gaining $100. Loss aversion favors inaction over action and the status quo over any alternatives. Therefore, when it comes time for us to act upon the facts and data we have gathered and the analysis we have undertaken about them, biases 2 and 3 – unjustified optimism and unreasonable risk aversion – conflict. As a consequence, we tend to make bold forecasts but timid choices.
