What Would Change My Mind

• If SPY breaks below $758 and closes there for two consecutive sessions while VIX breaks above 18, dealer short gamma hedging accelerates mechanically into equity selling, reversing the cushion that negative gamma currently provides as a volatility brake. • If NVDA closes above $245 on volume >80M shares, the flip level converts from resistance to support structure, signaling dealer repositioning from short to long gamma and fundamentally altering the convexity dynamics that currently penalize upside momentum across the mega-cap complex. • If QQQ sustains a move below $700 for three days while implied vol in the 1-3 month stack inverts above realized vol by >4 points, the negative gamma thesis collapses into realized tail hedging demand, forcing dealers to buy into weakness instead of selling into strength.
