Introduction
Gamma Exposure (GEX) has become an increasingly important metric in modern options trading, providing traders with valuable insights into potential market movements and volatility. This article explores how GEX levels influence market dynamics and how traders can utilize this information in their trading strategies.
What is Gamma Exposure (GEX)?
Gamma Exposure represents the theoretical dollar value change in market makers’ delta positions for every 1% move in the underlying asset’s price. In simpler terms, it measures how much market makers need to buy or sell the underlying asset to maintain delta-neutral positions as prices change.
Key Components of GEX
1. Positive vs. Negative GEX
Positive GEX: Creates resistance to price movement
- Market makers sell into strength
- Buy into weakness
- Results in mean-reverting price action
Negative GEX: Amplifies price movement
- Market makers buy into strength
- Sell into weakness
- Can lead to trending price action
2. GEX Levels and Market Impact
High GEX Levels
- Indicate potential price stability
- Create “sticky” price points
- Often occur near major option strike prices
- Can act as support/resistance levels
Low GEX Levels
- Signal potential for larger price moves
- Indicate less market maker influence
- Can precede periods of increased volatility
- Present opportunities for trend-following strategies
