What Would Change My Mind

• If SPY closes below $759 on OPEX day while QQQ holds above $721 flip → negative gamma in the broad index decouples from mega-cap positive gamma, forcing dealer deltas into asymmetric hedging and breaking the current structural coherence. • If NVDA breaks below $220 (below the $221 flip) on elevated volume while AAPL remains bid above $336 → positive gamma concentration in mega-cap growth collapses into single-name tail risk, invalidating the thesis that breadth supports the current regime. • If implied volatility term structure inverts (front month VIX premium compresses to zero) into final OPEX hour while SPY gamma remains negative → dealer positioning flips from mechanical support into mechanical selling, structurally reversing the positive gamma dominance across the tape.
