What Would Change My Mind

• If QQQ breaks above $725 flip and holds through $728 on volume >22M shares → negative gamma unwinds into dealer long-gamma rehedging, inverting the tape structure from mechanical selling to bid-chasing behavior. • If AAPL rallies through $335 flip to $338–$340 range while IVR stays compressed below 50 → gamma deficiency thesis breaks because dealer short-gamma exposure converts to mechanical buying rather than pin risk, contradicting the asymmetric downside setup. • If SPY sustains a move below $760 on three consecutive closes with VIX rising above 18 and staying there → negative gamma accelerates into a structural volatility spike that forces gamma-short dealers to hedge upward, negating the current pin-risk dominance in favor of realized volatility blow-through.
