As of May 15, 2026, Alpha and Omega Semiconductor Limited (AOSL) has positive net gamma exposure of $228.7K under the standard dealer-hedging convention. Net delta exposure is -$17.9M. 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.
AOSL Strategy Sizing in the Current GEX Regime
Alpha and Omega Semiconductor Limited is in a positive dealer-gamma regime ($228.7K). Net dealer delta of -$17.9M 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.
