What Would Change My Mind

• If SPY sustains above $742 through FOMC decision with QQQ holding $692+, negative gamma regime breaks as dealer short-gamma positions face forced covering, reversing the rally-brake mechanism into mechanical upside acceleration. • If NVDA fails to reclaim the $210 flip level and closes below $207 on three consecutive sessions, the tech concentration that's anchoring QQQ's gamma structure deteriorates, forcing portfolio rebalancing that could cascade into broader negative convexity unwinding. • If Fed guidance signals sustained higher rates and 2-year yield breaks above 4.35% in tandem with SPY dropping to $735, the structural incentive shifts from dealer hedging as brake toward gamma-driven downside as trapped call sellers become forced sellers, inverting the current risk asymmetry.
