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 SW gamma exposure
The SW options chain represents Smurfit Westrock and its exposure to commodity prices, industrial demand, capacity, and input costs. Its GICS classification is Paper and Plastic Packaging Products and Materials. Use the chart to identify where modeled exposure is concentrated and whether that concentration is consistent across expiration choices.

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