Cognitive Biases in Trading

Action

Cognitive biases frequently manifest as impulsive decisions within trading, particularly impacting cryptocurrency and derivatives markets where rapid price fluctuations are common. The disposition effect, for instance, leads traders to realize gains too quickly while holding onto losing positions for too long, driven by a desire to avoid acknowledging errors. This behavioral pattern directly contradicts optimal portfolio rebalancing strategies predicated on quantitative risk assessment and efficient market hypothesis principles. Consequently, action bias, the tendency to trade even when inaction is preferable, increases transaction costs and diminishes overall returns, especially in low-volatility environments.
