What Would Change My Mind

• If SPY breaks below $765.50 on a close and stays there through Thursday's cash close, the gamma-long positioning in mega-cap tech unwinds mechanically as dealers flip to net short convexity, forcing synthetic deleveraging across the QQQ complex. • If NVDA fails to hold $223.00 and rolls below $221.50 with volume >25M shares/hour, the IV rank compression we're seeing in that name reverses into expansion, breaking the synchronized volatility regime that's keeping the positive gamma cohort intact. • If QQQ trades above $729.50 but then closes below $728.00 on the same day, it creates a gap-fill structural setup that invalidates the upside gamma acceleration thesis and suggests dealer re-hedging is cap-constrained rather than momentum-driven.
