QSI Strategy Sizing in the Current GEX Regime
Quantum-Si incorporated is in a positive dealer-gamma regime ($19.4K). Net dealer delta of -$2.1M 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.
