As of May 15, 2026, Core & Main, Inc. (CNM) has positive net gamma exposure of $15.5K under the standard dealer-hedging convention. Net delta exposure is -$1.8M.

CNM Strategy Sizing in the Current GEX Regime
Core & Main, Inc. is in a positive dealer-gamma regime ($15.5K). Net dealer delta of -$1.8M 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.
