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 BAC gamma exposure
Bank of America's low share price keeps its options affordable, so BAC options draw both institutional hedging in the monthly expirations and retail trading in the weeklies. Dollar strike spacing packs open interest into a narrow band, so the call wall and put wall usually sit close to the current price.
What distinguishes BAC from JPM as a gamma market is its balance-sheet sensitivity to interest rates. The bank's large held-to-maturity securities portfolio is the reason, and BAC gamma often builds into FOMC meetings and moves in long-term yields. When deposit costs or unrealized securities losses are in the news, compare the put wall across expirations to see whether put-side exposure is growing.

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