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.
GEX walls are price levels where dealers hedge aggressively. Price tends to gravitate toward Max Pain and stall near walls.
