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 methodology and limitations
QuantWheel calculates UNH GEX from the selected expirations, available options data and the formula displayed in the calculator. The result summarizes modeled gamma exposure by strike.
GEX is a model output, not observed dealer inventory or a price forecast. Open interest does not identify who owns an option, and the displayed call wall, put wall and gamma flip can change when the inputs or selected expirations change.
UNH GEX FAQ
What is UNH GEX?
UNH GEX estimates gamma exposure across listed UNH options using option gamma and open interest. It helps you compare how modeled exposure is distributed by strike and expiration. UNH GEX does not reveal actual dealer positions or predict where UNH will trade.
How do I read the UNH call wall and put wall?
QuantWheel labels the UNH call wall as the strike with the largest positive modeled GEX and the UNH put wall as the strike with the largest negative modeled GEX in your selected data. Compare both with the UNH price and expiration choices. They are reference levels, not guaranteed support or resistance.
What is the UNH gamma flip?
The UNH gamma flip is the price where modeled net gamma crosses zero for the selected UNH options data. Compare it with the current price and the shape of the strike chart. The UNH gamma flip is a model output, not a trading signal.
Which expirations should I use for UNH GEX?
Start with the nearest UNH expiration to study short-dated positioning, then add later expirations to compare a broader part of the options chain. Each selection changes which UNH contracts are included, so compare one expiration with a combined view before drawing conclusions.
Is the UNH GEX calculator free?
Yes. You can run up to three free UNH GEX calculations per day on the public tool. After using those calculations, continue for free in the GEX Sandbox. Check the current QuantWheel pricing page for plan access details.
