What Would Change My Mind

• SPY breaks below $756 and fails to recapture in 3 consecutive sessions → negative gamma acceleration shifts from tactical amplifier to structural regime, forcing dealer short-delta hedging into mechanical selling that overwhelms vol-premium decay • QQQ sustains above $722 through FOMC decision while VIX contracts below 14.5 → gamma regime flips positive as short-dated call spreads expire worthless, reversing the dealer hedging flow and signaling convexity stabilization into monthly OPEX • NVDA holds above $232.50 while AAPL reclaims $333 simultaneously → mega-cap concentration breaks the negative gamma linkage, suggesting dealer hedging pressure detaches from breadth and tilts structural narrative toward selective volatility rather than systemic amplification
