What is Gamma Exposure (GEX)?
Gamma Exposure represents the sensitivity of an option's delta to changes in the underlying price. Market makers hedge their gamma exposure, creating support/resistance at high GEX strikes.
Key Levels:
- Call Wall: Strike with highest positive GEX (resistance)
- Put Wall: Strike with the largest put GEX, shown as the deepest negative bar (support)
- Gamma Flip: Where total GEX changes from negative to positive
Positive GEX: Market makers sell into rallies, buy into dips (stabilizing).
Negative GEX: Market makers buy into rallies, sell into dips (amplifying moves).

Understanding PFE gamma exposure
Pfizer trades at a low nominal price with a high dividend yield, and that combination defines its options market: dense dollar-spaced strikes, heavy covered-call writing from income holders, and gamma packed tightly around spot. The result is one of the most persistently positive gamma profiles in large-cap healthcare, where dealer hedging suppresses volatility and the call wall acts as a firm ceiling on the modest rallies this stock produces.
The gamma profile is anchored by yield rather than growth. The put wall tends to sit at round-dollar strikes that correspond to dividend-yield thresholds income investors have historically defended, which gives those levels a fundamental basis most gamma levels lack. Catalysts are pipeline news and patent-cliff commentary rather than quarterly beats, and because the strike ladder is so dense, a single dollar of price movement can shift which strike carries the most gamma - worth remembering before treating any individual wall as decisive.

PFE GEX FAQ
What is PFE GEX (gamma exposure)?
PFE GEX measures the aggregate gamma that options market makers carry across all PFE strikes and expirations. When PFE GEX is positive, dealer hedging dampens price moves (selling rallies, buying dips); when it is negative, hedging amplifies moves. It is calculated from open interest and each contract's gamma across the Pfizer Inc. options chain.
What is the PFE call wall and put wall?
The PFE call wall is the strike with the largest positive gamma exposure and often acts as resistance, while the PFE put wall is the strike with the largest negative gamma exposure and often acts as support. As of the latest snapshot, the call wall is at $25, the put wall is at $24, the gamma flip level is near $24.10.
What is the PFE gamma flip level?
The PFE gamma flip (zero-gamma) level is the price where net dealer gamma crosses from positive to negative. Above it, market-maker hedging tends to suppress PFE volatility; below it, the same hedging amplifies moves in both directions. The latest computed flip level is near $24.10.
