Weekend Gap Down Into Negative GEX With Gold Bid — Caution At Open

GAMMA BRIEF AI Generated 2026-08-24

SPY is opening Monday with a modest cash gap down of 1.34 points vs Friday's close, while gold is surging +1.00% in pre-market — a classic risk-off divergence worth watching. The SPY put wall sits at 765 and call wall at 766, meaning the pre-market print of 764.38 is already parked below both walls in a compressed options corridor with negative net GEX of -$6.80B.

The Nasdaq (QQQ) is showing the sharpest cash gap of the three majors at -0.63% vs Friday's close, now sitting well below its own put wall at 713. Meanwhile IWM is nearly flat on the weekend and hugging its 300 call wall — the small-cap picture is structurally different from large-cap tech. With 0DTE expirations active today across SPY, QQQ, and SPX, the first hour will likely be volatile and decisive.

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.
