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 MAS gamma exposure
MAS provides options exposure to Masco, which operates in building products. Earnings and shifts in orders, production, capital spending, and end-market demand can change option pricing and open interest. The GEX chart shows how modeled exposure is distributed for the contracts and expirations you include.
For MAS, compare a single expiration with a combined view before interpreting the call wall, put wall, or gamma flip. Changes in open interest and the contracts selected can shift the modeled profile. These levels describe the selected options data and do not predict where Masco will trade.

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