BIO Strategy Sizing in the Current GEX Regime
Bio-Rad Laboratories, Inc. is in a negative dealer-gamma regime ($971.2K). Net dealer delta of $5.0M sets the size of the directional hedging flow that fires as spot moves. In this regime, momentum and breakout strategies fit the regime: long calls or puts, ratio backspreads, calendar spreads positioned for vol expansion. Realized volatility tends to overshoot implied during negative-gamma stretches, hurting indiscriminate short-vol exposure. 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.
