Dr. NoVo · Pre-Market Primer

BOTTOM LINE: Equities enter the cash open with broad market and tech dealers flipped short gamma, setting up an amplifying session where directional slippage can easily extend unless small caps stem the bleed. THE SETUP Index futures softened through the European morning as Friday’s cool +29,000 payrolls print gives way to growth scrutiny ahead of S&P Global and ISM Services PMIs. On Hyperliquid, the S&P 500 perp sits -0.02% and the Nasdaq 100 perp is -0.11% against Friday's cash close, with early strength in MSFT (+0.67%) and NVDA (+0.62%) failing to offset drag from AAPL (-0.40%), TSLA (-0.40%), GOOGL (-0.29%), and META (-0.22%), while offering no structural read on small caps. With ES slipping below VWAP overnight and a modest cash gap down, expect volatility expansion rather than a tight morning hold. DEALER POSITIONING Market makers sit in negative gamma on both SPY and QQQ, meaning dealers must sell into weakness and buy into strength, an amplifying regime that accelerates trend extensions rather than absorbing them. In contrast, IWM remains in positive gamma, where dealer hedging acts as shock absorption, dampening moves into mean reversion. The broader options book reflects this divergence: downside put skew is bid across tech and small caps, leaving SPY and QQQ vulnerable to slippage while IWM resists clean continuation. LEVELS TO WATCH For SPY, holding pre-market low support at 767.97 and yesterday's low at 767.14 keeps price above the put wall at 765.00; losing 767.14 confirms the negative gamma breakdown. Reclaiming after-hours support at 768.99 and pre-market high resistance at 769.88 is required to challenge the after-hours high at 770.16 and yesterday's high at 772.65. Across QQQ and IWM, watch if small-cap stability can check tech's amplifying downside drift, or if failure below pre-market lows drags the entire complex lower.

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.
