Cognitive Dissonance
Cognitive dissonance occurs when a trader holds two contradictory beliefs or experiences a conflict between their beliefs and market reality. For instance, a trader may believe they are a disciplined risk manager, but they find themselves over-leveraging during a period of high volatility.
This psychological tension is uncomfortable, often leading the trader to rationalize their behavior rather than changing it. In the context of financial derivatives, this can manifest as holding a losing position long after it should have been closed because the trader cannot accept that their original thesis was wrong.
To reduce this dissonance, traders often double down on bad positions, hoping for a turnaround that validates their initial decision. Resolving this requires the mental strength to accept that market reality overrides personal beliefs.
