SPY kissed the call wall then faded hard; IWM holds while QQQ collapses below 740

GAMMA BRIEF AI Generated 2026-06-22

Monday's session opened with a bang — SPY tagged 750.12, touching the 750 call wall to the tick, before reversing sharply to 744.81. Meanwhile, QQQ has given back its entire pre-market premium and more, now sitting at 736.36 after printing a session high of 745.42 well above the 740 call wall.

The divergence across the major indices tells the real story: IWM is the lone holdout at 297.53, up 0.66% on the day and the only index still green heading into the afternoon. With 0DTE volume at 76.9% of SPY flow and $357M in SPX put sweeps printed at the open, the afternoon setup is not clean — bearish trend bias across all three names, negative GEX amplification risk, and a VIX that has quietly crept from its session low of 16.49 to 17.44.

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.
