Gamma Pinning

Gamma pinning is a phenomenon where the price of an underlying asset is drawn toward a specific strike price as an expiration date approaches. This occurs when large amounts of gamma are concentrated at that strike, causing market makers to hedge in a way that pushes the price toward that level.

As the price gets closer to the strike, the gamma of the options increases, intensifying the hedging pressure and reinforcing the pin. This can lead to reduced volatility as the price becomes stuck in a narrow range.

Gamma pinning is a direct result of the reflexive relationship between market maker hedging and price action. It is a critical concept for traders looking to understand price behavior during the final days of an option's life.

It showcases the structural influence of derivatives on the underlying market.
