Market Maker Delta

Market maker delta refers to the net exposure a liquidity provider maintains in an underlying asset while managing their options or derivative book. Because market makers provide two-sided quotes, they often accumulate positions as they fill buy and sell orders from other traders.

To remain delta neutral and avoid directional risk, they must constantly hedge their positions by trading the underlying asset. This dynamic hedging activity can significantly influence market volatility, especially during large price movements.

When market makers are forced to buy or sell the underlying asset to maintain their delta, it can create feedback loops that accelerate price trends. This process is known as gamma hedging, where the sensitivity of the delta to price changes forces further trading.

Understanding this interaction is crucial for analyzing how derivative markets impact spot price discovery.
