What is the current MU gamma exposure (GEX)?

As of May 18, 2026, Micron Technology, Inc. (MU) net gamma exposure is positive at $74.9M under the standard dealer-hedging convention. Net dealer delta exposure is -$44.88B. GEX aggregates the gamma sitting on dealer books across all listed strikes and expirations.

Is MU in positive or negative dealer gamma right now?

MU is currently in positive dealer gamma. Dealers net long gamma buy underlying weakness and sell into rallies to maintain delta-neutrality, which dampens realized volatility and tends to pin price near heavy open-interest strikes.

What does MU GEX tell options traders?

GEX is a regime indicator: positive-gamma regimes favor mean-reverting strategies (premium-selling near established ranges); negative-gamma regimes favor momentum and breakout strategies. The same options-strategy structure can be appropriate or inappropriate depending on the dealer-gamma regime, so reading the sign and magnitude of net GEX before sizing positions is standard practice.

As of May 18, 2026, Micron Technology, Inc. (MU) has positive net gamma exposure of $74.9M under the standard dealer-hedging convention. Net delta exposure is -$44.88B. Positive GEX means dealers are net long gamma: they buy into dips and sell into rallies, damping realized volatility and often causing price to pin near heavy open-interest strikes.

MU Strategy Sizing in the Current GEX Regime

Micron Technology, Inc. is in a positive dealer-gamma regime ($74.9M). Net dealer delta of -$44.88B sets the size of the directional hedging flow that fires as spot moves. In this regime, mean-reverting strategies fit the regime: credit spreads, iron condors, covered calls near established ranges. Realized volatility tends to undershoot implied during positive-gamma stretches, supporting the short-vol structures. The gamma-flip level - the spot price at which net dealer gamma changes sign - is the most actionable anchor for sizing: through-flip moves trigger qualitatively different hedging behavior than within-regime moves, so risk-defined structures sized to the current spot may not stay sized correctly if a flip is near.

Reading the MU gamma exposure profile

The per-strike GEX bars above show where dealer hedging will fire as spot moves through each strike. Net dealer gamma is positive at $74.9M, so as spot moves dealers sell rallies and buy dips, mechanically dampening realized volatility. Net dealer delta of -$44.88B sets the size of the directional hedging flow that fires as spot moves: a 1% move in MU triggers approximately $448.8M of dollar hedging. Net vega of -$208.0M measures how dealer P&L scales with implied-volatility shifts - a 1-point IV move shifts dealer book value by approximately that amount per vol point. Gamma concentration ratio is 0.02, a measure of how clustered dealer gamma is around the current spot - higher concentration means more violent hedging when spot crosses key strikes.

MU GEX regime and trading style

In the current positive-gamma regime, Micron Technology, Inc. realized volatility tends to undershoot implied, supporting short-vol structures: credit spreads near established ranges, covered calls, iron condors with wings just outside the dealer-supported band. Risk: a regime flip into negative gamma typically arrives with a spot drop through a gamma-flip strike, after which the same structures get hit by accelerating moves. The current expected move of 25.31% is the anchor for sizing wings - structures with wings at ±1σ collect ~68% probability of staying inside the band.

How dealer hedging on MU feeds spot tape

Dealer hedging is mechanical, not opinionated - the flow is the inverse of options buyer/seller positioning. Long-gamma dealers sell into rallies and buy into dips, narrowing intraday ranges. That is the mechanism behind the "pin to max pain" pattern. The gamma-flip strike is the most actionable single number on this page: cross it and the entire hedging regime inverts. Through-flip moves typically come with regime-change in realized volatility, not just direction.

Practical caveats for trading MU GEX

Dealer-gamma exposure is a model output, not a measured quantity. The figures here use the standard assumption that customers buy options and dealers are short the inventory, hedged delta-neutral. Reality has more texture: dealers occasionally net long inventory after option-overwriter ETF flows or systematic vol-target strategy rolls, in which case the sign of the regime inverts from what the GEX page implies. MU's current put/call volume ratio of 0.85 is a quick proxy for whether the customer-side flow is balanced; ratios well above 1.0 or below 0.6 are the regimes where the dealer-short-gamma assumption is most fragile. Cross-check with the IV-rank context on the volatility page: high-IV-rank regimes tend to coincide with negative gamma even when the headline number prints positive, because realized vol is already running hot enough to make hedging flows reactive rather than damping. When the implied move sits above 4% (25.31% here), the entire gamma profile compresses into the near-expiration tenors and the longer-dated GEX number becomes less actionable. Treat the gamma sign as a probability tilt, not a deterministic prediction.
