Bears opened fire early; 0DTE sweeps called the selloff before price moved

GAMMA BRIEF AI Generated 2026-08-24

Monday's session looked orderly on the surface — SPY closed down just -0.32% — but the range told a different story. Tech bore the brunt: QQQ shed -1.05% and NVDA collapsed -3.03%, while a pre-open barrage of bearish 0DTE sweeps totaling over $330M in premium telegraphed the directional intent before the opening bell even rang.

Small-caps and mega-cap tech diverged sharply from defensive names. AAPL and MSFT closed green while TSLA shed -4.08% and IWM logged a -55 trend bias score with 78% confidence. Gold caught a bid as equities softened, and the bond market faces a catalyst-heavy week ahead. Tuesday's setup is not clean — here's what the positioning says.

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
