Understanding Gamma Exposure (GEX)
What is GEX?
Gamma Exposure (GEX) measures how sensitive options market makers’ portfolios are to changes in the underlying asset’s price. As the underlying moves, dealers adjust their Delta hedges, buying or selling stock or futures to stay neutral. The size and sign of GEX help estimate how aggressive those hedges may be.
For traders, GEX is a way to visualize the options dealer book and estimate where hedging flows may dampen or amplify price moves.
How to Interpret the Charts
High positive GEX values often create a stabilizing effect: dealers tend to sell into rallies and buy into dips, which can “pin” price near large strikes. When GEX turns negative, the behavior flips — dealers buy into rallies and sell into dips, potentially accelerating moves and increasing realized volatility.
The Zero Gamma level is a key pivot where this hedging behavior is expected to change sign, and it frequently behaves like an important support or resistance zone on the chart.
Practical Applications
- Identify key price levels where volatility might increase or collapse.
- Gauge overall market tone by observing the balance between Call GEX and Put GEX.
- Anticipate potential “pinning” near large open interest strikes into options expiration.
- Align intraday trading plans around Zero Gamma pivots and major GEX walls.
