NoVo Analyst · Pre-Market Primer

BOTTOM LINE: A strong pre-market gap pushed SPY and tech above their immediate flip levels, but surging energy costs and sticky August CPI keep broad structure vulnerable to fast volatility expansion if liquidity thins. THE SETUP The equity complex enters the cash open with a sharp upside gap following overnight momentum that absorbed yesterday's wholesale inflation shock. August CPI printed at +0.4% month-over-month (+3.4% annually), matching headline forecasts while core CPI ticked up to +0.3% MoM. With Brent crude holding above $105 per barrel and short-term yields remaining elevated ahead of next week's FOMC meeting, today's session is primed for aggressive price discovery rather than a passive range-bound drift. DEALER POSITIONING The three major benchmarks are opening with divergent dealer postures. SPY ($764.94) has reclaimed its gamma flip ($764.74) into positive net GEX (+$0.03B), shifting market makers from amplifying moves into dampening them via mean-reverting hedging. QQQ ($716.15) has likewise cleared its flip level, turning tech into a stabilizing buffer. Conversely, IWM ($290.68) remains trapped in a short-gamma posture below its flip; small caps must absorb mechanical dealer selling on any dip, leaving them visually weaker than tech. Options order flow across the complex shows puts bid with a heavy net-short delta tilt, keeping systemic downside vega exposure high. LEVELS TO WATCH For SPY, holding above support at the pre-market low of 760.39 and yesterday's high of 760.09 preserves the bullish gap structure, with buyers eyeing the 766.53 pre-market high toward the 770.00 call wall. A failure that breaks back below 764.74 places spot back into negative dealer gamma, opening downside risk toward gravity at 762.40 and the 760.00 put wall. For QQQ and IWM, retaining their morning gap zones above prior-session balance is mandatory to prevent short-gamma acceleration from spilling across the entire complex.

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.
