- Options contracts across various expirations on SPY and SPX
Concepts & Methodologies
Gamma Exposure (GEX)
- Used to identify where option dealers (e.g., Citadel, BlackRock) are concentrated in the market by analyzing gamma exposure levels across strike prices and expirations.
- Gamma exposure levels indicate supply and demand zones where dealers hedge their portfolios.
Delta Hedging and Gamma Hedging
- Dealers hedge their option books by buying or selling shares of the underlying security to manage risk.
- Positive gamma exposure: Dealers sell shares as price rises and buy as price falls, compressing volatility.
- Negative gamma exposure: Dealers buy shares as price rises and sell as price falls, fueling momentum and expanding volatility.
Gamma Exposure Analysis Framework
- Aggregate option contracts across all expirations and strikes.
- Calculate total gamma exposure and identify if it is positive or negative.
- Benchmark current gamma exposure against historical extremes (SPY ranges from -4 billion to +4 billion; current ~85 million positive gamma).
- Identify strike price concentrations where gamma exposure clusters (e.g., 530-535 for SPY currently).
- Analyze dealer hedging behavior based on gamma sign (positive or negative).
- Use gamma exposure to predict price pinning/tagging at high concentration strikes.
- Formulate trading strategies around these levels and gamma exposure context.
Trading Strategies & Examples
-
Short-term (0-2 days to expiration):
- Trade near high gamma exposure strikes (e.g., 530 strike on SPY).
- Use butterfly spreads to capture theta decay as price hovers near strike.
- Sell puts or buy call debit spreads depending on bullish/bearish tilt.
-
Medium to Long-term (2-4 weeks or more):
- Use gamma surface to identify future concentration zones (e.g., 535 strike on May 31 or June 21 expiration).
- Sell put credit spreads (e.g., 530/525 put credit spread) for bullish bias.
- Buy butterfly spreads targeting future high gamma strikes.
Macroeconomic / Market Context
- Gamma exposure data reflects dealer positioning and hedging, which influences volatility and price movement.
- Positive gamma exposure environments tend to compress volatility.
- Negative gamma exposure environments tend to expand volatility and momentum.
Risk Management & Performance Metrics
