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 MU gamma exposure
MU is a common way to trade the memory cycle in options, and the AI buildout, with high-bandwidth memory (HBM) demand tied to accelerator shipments, has made its gamma profile busier. MU gamma builds into its earnings reports, which arrive weeks before most large tech companies report and are watched across the semiconductor sector. The report often moves the stock across its whole near-the-money gamma range.
Memory stocks move in long boom and bust cycles, and MU's gamma regime often changes with them, from positive gamma in upcycles to negative gamma when pricing or inventory data turns. Compare the gamma flip across expirations when memory pricing or inventory data arrives. The flip describes the selected options data and does not predict the cycle.

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