Anchoring Effect in Options Pricing

The anchoring effect occurs when an individual relies too heavily on an initial piece of information, known as the anchor, when making subsequent judgments or decisions. In options trading, the initial price at which an asset or contract is purchased often serves as a psychological anchor.

Traders may refuse to sell an underperforming option because they are anchored to the price they paid, hoping it will return to that level regardless of market fundamentals. This prevents effective stop-loss implementation and rational portfolio rebalancing.

Furthermore, market participants may anchor their expectations for volatility or price targets on historical highs or lows, failing to adjust to new information or changing market microstructure conditions. This rigid attachment to initial data points hampers agility and risk mitigation.
