Gap-and-grind session closes flat but IWM defies bearish call at call wall

GAMMA BRIEF AI Generated 2026-06-02

Tuesday delivered a textbook gap-and-fade session: SPY opened above prior close, ran to 760.40, then drifted back to close essentially unchanged at 759.77. The real story was IWM — a name flagged bearish into the afternoon — which instead closed at 291.47, within striking distance of its 292 call wall, quietly outperforming the narrative.

Under the hood, two massive SPX blocks — an $824M call at 6000 and a $1.47B put at 8000, both June 18 expiry — sit as the session's most consequential footprints. Meanwhile, a pair of 0DTE QQQ call sweeps totaling $171M at the 744 and 745 strikes printed bullish and got paid. Positioning is shifting ahead of Wednesday's Broadcom earnings, and the gamma structure has reset with new walls.

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.
