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 ARM gamma exposure
Arm's business model - licensing instruction-set architecture and collecting royalties rather than manufacturing chips - gives it a valuation the market struggles to anchor, and that uncertainty shows up directly in its gamma exposure. Implied volatility runs high for a company with such predictable revenue, because the debate is about multiple rather than fundamentals, and options traders express that debate through wide-ranging directional bets.
A second structural factor matters here: SoftBank retains a very large majority of the shares outstanding, so ARM's effective float is far smaller than its market capitalization suggests. Thin float plus heavy options interest is the classic setup for gamma amplification, and ARM has delivered it - call-side gamma building above spot has repeatedly produced moves larger than the underlying news warranted. The put wall is the more reliable of its two walls, since downside hedging is less crowded than upside speculation.

ARM GEX FAQ
What is ARM GEX (gamma exposure)?
ARM GEX measures the aggregate gamma that options market makers carry across all ARM strikes and expirations. When ARM GEX is positive, dealer hedging dampens price moves (selling rallies, buying dips); when it is negative, hedging amplifies moves. It is calculated from open interest and each contract's gamma across the Arm Holdings plc options chain.
What is the ARM call wall and put wall?
The ARM call wall is the strike with the largest positive gamma exposure and often acts as resistance, while the ARM put wall is the strike with the largest negative gamma exposure and often acts as support. As of the latest snapshot, the call wall is at $300, the put wall is at $250, the gamma flip level is near $267.98.
What is the ARM gamma flip level?
The ARM gamma flip (zero-gamma) level is the price where net dealer gamma crosses from positive to negative. Above it, market-maker hedging tends to suppress ARM volatility; below it, the same hedging amplifies moves in both directions. The latest computed flip level is near $267.98.
