QQQ cracks -0.75% while SPY holds flat — tech leads the divergence

GAMMA BRIEF AI Generated 2026-10-13

Tuesday opens with a sharp split under the hood: QQQ is gapping down 0.75% vs yesterday's close, with Nasdaq futures fading hard into the open — /NQ is sitting at 94% below its globex range at 30,657, down nearly 387 points from session highs. Meanwhile SPY is essentially flat (-0.08%) and IWM is unchanged, meaning this is a tech-specific story, not a broad equity selloff.

The options market adds texture: SPY is trading above its own call wall at 775, but QQQ is pinned right at its put wall at 740 — a level where negative gamma could amplify moves in either direction. With no major economic data due today and earnings season ramping up per this morning's headlines, the session setup is one of tech weakness against a backdrop of resilient large-cap breadth.

Dealer positioning shows a clear regime shift as options market makers adjust hedges across the curve. The put-call skew has compressed significantly, suggesting institutional players are reducing downside protection.

Watch the key level closely at open — it sits exactly at the intersection of the GEX zero line and overnight VWAP. A clean break above opens the path to the call wall; rejection sends us back toward the put wall.

ⓘ Trend Bias vs Directional Call

The badge shows momentum bias — where price sits relative to VWAP and moving averages right now. The brief's directional call weighs GEX structure, options flow, and macro signals, and may point the opposite direction when a rally runs into a call wall or flow turns bearish.

GEX walls are a snapshot from brief generation — not a live feed.

Got it, don't show again

GEX walls are price levels where dealers hedge aggressively. Price tends to gravitate toward Max Pain and stall near walls.
