What Would Change My Mind

• If SPY closes above $760 tomorrow through OPEX expiry with IVR remaining above 90, the negative gamma structure flips from dealer short to dealer long, eliminating the mechanical downside compression thesis entirely.
• If NVDA breaks and holds above $217.50 while QQQ remains below $712, sector rotation away from mega-cap concentration becomes structural rather than tactical, invalidating the unified tech regime fragmentation narrative.
• If VIX settles below 12.5 at OPEX close despite the 4-4 regime split, it signals dealers have successfully neutralized positioning without repricing, meaning volatility expansion was priced in advance and the violent move thesis becomes a fade rather than a setup.
