Dr. NoVo · Pre-Market Primer

BOTTOM LINE: Equities face an unstable open as surging yields lock SPY, QQQ, and IWM into synchronized short-gamma regimes where mechanical dealer hedging accelerates downward momentum. THE SETUP Equities are gapping down -0.34% pre-market as higher-than-expected core CPI data and a 10-year Treasury yield pressing above 5.30% weigh on equity valuations [1]. Hyperliquid perps show direct de-risking since Wednesday's cash close, with the S&P 500 perp -0.38% and the Nasdaq 100 perp -1.28%, dragged lower by mega-cap weakness in NVDA (-2.13%), TSLA (-1.48%), AMZN (-1.35%), and META (-1.28%) against relative stability in AAPL (+0.68%) and MSFT (-0.38%). There is no liquid small-cap perp, so offshore flow provides no read on IWM, but cash futures spent the overnight session probing lower before coiling near pre-market VWAP. DEALER POSITIONING Market makers sit synchronized in negative gamma across all three complexes: SPY, QQQ, and IWM. In this environment, dealers do not absorb shocks by buying dips; instead, mechanical delta hedging forces them to sell into declines and buy into rallies, magnifying intraday moves. Tech remains the heaviest pocket of the book, evidenced by aggressive dealer selling in QQQ (-2.6M shares) compared to SPY (-551K shares) and IWM (-109K shares). Skew across the board leans defensive with puts bid, meaning any fresh cascade lower will meet expanding short-gamma acceleration rather than structural dip-buying. LEVELS TO WATCH For SPY ($767.05), immediate support sits at the 766.71 prior-day and after-hours low, followed by the 765.00 put wall and the 764.10 pre-market low; failing to hold 764.10 unpins dealers and leaves downside momentum unhedged toward the 762.53 gravity level. To stall the selloff, buyers must clear pre-market resistance at 768.25 and after-hours resistance at 769.69, targeting the 774.68 gamma flip where dealer hedging would finally neutralize. Across QQQ and IWM, watch whether small caps continue to resist tech's outsized drag, or if breaks below their respective put walls trigger broad selling in unison.

FLOW DYNAMICS Charm — in a negative-gamma regime, decay doesn't pin; moves can extend into the close. Vanna — with dealers short gamma, a drop in vol would ease the amplification and let the tape settle. Second-order dealer flow context.
