Weekly Expiry Pin Holds; VIX Crushed While Gold Surges and MSFT Explodes

GAMMA BRIEF AI Generated 2026-05-29

Friday's session was a masterclass in gamma containment: SPY closed essentially flat on the day at 756.03, its range defined almost entirely by the 755 put wall below and the 760 call wall above — exactly the structure the GEX positioning predicted. The weekly expiry pin thesis played out in full, with price never threatening either wall in a sustained way and realized volatility compressing hard alongside a VIX that cratered 8.21% to 15.32.

Beneath the surface, the day was anything but quiet. MSFT surged 3.26% on the session in a move that did nothing to lift the broad tape — SPY net unchanged, QQQ -0.04%. Gold added 1.11% and silver 2.76%, while a $93M SPX put sweep at the 7600 call wall struck late in the session signals that at least one institutional hand is bracing for a reversal heading into Monday, June 1.

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.
