Dr. NoVo · Pre-Market Primer

BOTTOM LINE: Equities face a fragile open as an in-line CPI print fails to lift index perps, leaving SPY and QQQ vulnerable to amplifying selling while IWM retains dampening dealer insulation. THE SETUP An overnight gap lower of -0.31% follows an 08:30 volume flush after the September CPI report met expectations, keeping Treasury yields steady and Fed pause pricing intact while failing to restore buying momentum. On Hyperliquid, the S&P 500 perp has the market -0.31% and the Nasdaq 100 perp has it -0.65% since Tuesday's cash close, weighed down by NVDA (-1.10%), TSLA (-0.81%), and META (-0.57%) against green prints in AAPL (+0.80%), GOOGL (+0.79%), AMZN (+0.12%), and MSFT (+0.09%). There is no liquid small-cap perp, so offshore flow offers no direct read on IWM, leaving today's session set up as an active structural divergence rather than broad macro consensus. DEALER POSITIONING The three index ETFs split mechanically across dealer regimes: SPY and QQQ sit in negative dealer gamma, an environment where market makers must sell into declines and buy into rips, amplifying directional price extension. In contrast, IWM sits in positive dealer gamma, where hedging absorbs momentum and forces mean-reverting chop. Options skew tilts defensive with puts bid in tech, while net dealer hedging closed Tuesday with selling across SPY (-513K shares) and QQQ (-739K shares) against modest buying in IWM (+58K shares). LEVELS TO WATCH For SPY, holding beneath yesterday's low at 775.95 exposes pre-market support at 774.77, where a sustained break risks opening a slide toward the 770.00 put wall; reclaiming 775.95 and pushing through the 777.54 after-hours low is required to stabilize the tape and target after-hours resistance at 778.50 and the 780.50 pre-market high. For QQQ and IWM, watch whether tech extends its amplifying slide lower or small-cap positive gamma succeeds in anchoring broad equities.

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.
