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 most negative GEX (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 IWM gamma exposure
IWM gives options traders direct exposure to small-cap gamma dynamics, and its GEX profile behaves differently from the large-cap indices. Small caps are more sensitive to rates and credit conditions, so IWM's gamma regime can flip on macro data releases even when SPY stays comfortably in positive territory. Expirations are listed nearly every trading day and the chain is deep, making IWM one of the most traded ETF options markets after SPY and QQQ.
Because the Russell 2000 tends to move in wider percentage ranges than the S&P 500, negative-gamma episodes in IWM are frequently more violent — dealer hedging into a falling, illiquid small-cap market accelerates moves. The IWM put wall is therefore a level worth respecting, while the call wall often caps rallies during range-bound periods when premium sellers dominate the flow.

IWM GEX FAQ
What is IWM GEX (gamma exposure)?
IWM GEX measures the aggregate gamma that options market makers carry across all IWM strikes and expirations. When IWM 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 iShares Russell 2000 ETF options chain.
What is the IWM call wall and put wall?
The IWM call wall is the strike with the largest positive gamma exposure and often acts as resistance, while the IWM 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 $297, the put wall is at $291, the gamma flip level is near $299.32.
What is the IWM gamma flip level?
The IWM 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 IWM volatility; below it, the same hedging amplifies moves in both directions. The latest computed flip level is near $299.32.
