What Would Change My Mind

• SPY closes above $748 and holds through Friday's retest while QQQ breaks above $690 on volume → negative gamma thesis inverts as dealer short positions flip to net long, requiring them to buy dips instead of sell rallies. • NVDA breaks decisively through $200 (current flip zone at $230) with IV crush below 35% while AAPL holds below $340 → mega-cap tech de-risks faster than broad market, fragmenting the synchronized gamma structure that currently locks SPY and QQQ together. • VIX prints below 12 for three consecutive sessions while put/call ratios compress below 0.65 across all three indices → retail crowding into short volatility becomes the new dealer constraint, requiring unwind mechanics that contradict the current short-vega positioning thesis.
