NVDA Earnings Eve: SPY Pinned Near Negative GEX Put Wall, QQQ Fading Hard

GAMMA BRIEF AI Generated 2026-08-26

S&P 500 futures are up sharply versus Tuesday's settlement — but don't let that headline fool you. SPY is actually opening slightly lower versus yesterday's 4PM close, gapping down -0.15% to 764.75, with the Nasdaq tracking even weaker at -0.41%. The real story is what happens after the bell tonight, when NVIDIA reports earnings with a consensus estimate of $2.13 EPS — a print that could reprice the entire AI trade overnight.

For today's session, the options market is essentially placing a fence around prices. SPY is sandwiched between a put wall at 765 and a call wall at 766, both within a dollar of the current pre-market print. With 0DTE volume running at 76.4% of all SPY flow and net gamma exposure deeply negative at -$4.27B, dealer hedging dynamics are likely to amplify any directional move that breaks this narrow band — up or down.

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.

→SYNTHESIS | SPY trend bias is BULLISH (score 40, confidence 57%) yet net GEX is -$4.27B and price is below the put wall at 765 — the positive trend score and negative gamma positioning are in direct conflict, with GEX implying amplified downside risk if 765 does not hold.
