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 BBY gamma exposure
Best Buy operates in computer and electronics retail, so its options may reflect earnings alongside changes in consumer demand, pricing, inventory, and operating margins. Review the full BBY strike profile, including both positive and negative modeled exposure, before interpreting the displayed walls.

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