For example, overconfidence can cause investors to underestimate risks and overestimate their knowledge about market movements.

These biases result in decisions that deviate from rational economic behavior, ultimately affecting market outcomes.

By incorporating these insights into investment practices, financial advisors can create diversified portfolios that account for both rational analysis and behavioral tendencies, enhancing overall performance and reducing risk.
