Loss aversion bias

Definition

Loss aversion bias is a psychological phenomenon where individuals prefer to avoid losses rather than acquire equivalent gains, often leading to irrational decision-making. This bias is rooted in the idea that losses have a more significant emotional impact than gains of the same size, influencing behaviors in investing and risk-taking. It often results in overly cautious financial decisions, such as holding onto losing investments too long or avoiding potential opportunities due to fear of loss.
