IWM runs, QQQ fades, SPY grinds — small-cap divergence wins the session

GAMMA BRIEF AI Generated 2026-05-25

Memorial Day Monday delivered exactly the split market the pre-market brief anticipated: small-caps outperformed while tech lagged, and the S&P 500 spent the session pinned in a narrow band. IWM tagged a session high of 286.52 before fading, while QQQ briefly pierced its 720 call wall — hitting 722.12 — before reversing hard back below, now sitting at 715.31. The large-cap story remains one of AI concentration anxiety, with NVDA off sharply from its session open of 220.90 to a last print of 214.30.

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.
