🎯 Quick Refresher: Options
Traders place bets on price movements:- Call Options → bet the price goes up
- Put Options → bet the price goes down
📈 Gamma
Gamma measures how sensitive an option’s delta is to price changes:- High gamma → very sensitive → frequent hedging
- Low gamma → less sensitive → less frequent adjustments
🌪️ Gamma Exposure (GEX)
GEX = total “market wind” from all options bets. It shows how much market makers must buy or sell the underlying to hedge:- Positive GEX → hedges against price moves → dampens volatility
- Negative GEX → hedges with price moves → amplifies volatility
💡 Why GEX Matters
GEX is a research lens for understanding market structure—not a trading signal or guaranteed edge:- Market Maker Hedging Context
Extreme GEX levels can highlight where hedging activity may be more concentrated. - Price Behavior Near GEX Zones
Stocks may tend to stabilize near high positive GEX or move more freely in negative GEX regimes—useful context, not a forecast. - Sentiment Insights
GEX trends can help illustrate market fragility or resilience over time. - Versatile Across Timeframes
- Intraday: volatility fading or breakout context
- Swing trades: positioning ahead of expiry cycles
- Macro: index positioning insights (e.g., SPX GEX)
🛠 Real-Life Analogy
GEX is like gravity on a marble board.
- Positive GEX → flat board → marbles roll to the center (stable)
- Negative GEX → tilted board → marbles accelerate outward (volatile)
