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 UNH gamma exposure
UnitedHealth spent years as one of the market's steadiest large caps before a run of medical-cost surprises, regulatory scrutiny and guidance withdrawals repriced both the stock and its options. Implied volatility now runs well above the level the market assigned this name historically, and its gamma exposure reflects a chain where nobody wants to be short volatility - a meaningful change from the systematic overwriting that used to dominate.
Because UNH is the highest-priced or near-highest-priced component of the price-weighted Dow, its moves have outsized influence on DIA's own gamma profile, which makes UNH gamma worth watching even for traders with no position in the stock. The put wall is the level that matters most in the current regime, marking where hedging demand against further guidance disappointments saturates. Treat the gamma flip level as a gap-risk indicator: this stock has demonstrated it can move far enough in one session to invalidate every wall on the board.

UNH GEX FAQ
What is UNH GEX (gamma exposure)?
UNH GEX measures the aggregate gamma that options market makers carry across all UNH strikes and expirations. When UNH 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 UnitedHealth Group Incorporated options chain.
What is the UNH call wall and put wall?
The UNH call wall is the strike with the largest positive gamma exposure and often acts as resistance, while the UNH 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 $430, the put wall is at $420, the gamma flip level is near $416.84.
What is the UNH gamma flip level?
The UNH 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 UNH volatility; below it, the same hedging amplifies moves in both directions. The latest computed flip level is near $416.84.
