What is Gamma Exposure (GEX)?
Gamma Exposure measures the net hedging pressure that options market makers face. When you buy an option, a dealer sells it to you - and they must hedge their risk by trading the underlying stock.
The Mechanics
- You buy a call option → Dealer is short the call
- To hedge, dealer must buy stock as price rises
- This hedging activity moves markets in predictable ways
Positive vs Negative Gamma
| GEX State | Dealer Behavior | Market Impact |
|---|---|---|
| Positive GEX | Buy dips, sell rips | Stabilizing - markets stay in range |
| Negative GEX | Chase momentum | Amplifying - moves get extended |
The "Gamma Flip" Level
There's a price level where dealer gamma flips from positive to negative. This is often a key support/resistance level.
- Above the flip: Dealers buy dips (support)
- Below the flip: Dealers sell into weakness (acceleration)
