⚠️ GEX METHODOLOGY NOTE: Primary GEX calculated at SPX close 7591.7 (Thursday, September 10). ES-implied regime (NEGATIVE) also computed for gap context at ES 7643.75. See methodology: gexlog.com/methodology

Cold Open

The August CPI report drops at 08:30 Eastern. Structure remains provisional until the print drops.

Hook

It is Friday, September 11th, 6:45 AM Eastern, and ES futures are trading at 7643.75. Yesterday's call warned of trend potential, and the session, driven by hot PPI and surging yields, delivered exactly that as the 7600 Put Wall breached. If the overnight gap holds through the open, we start with a buffer, but if it fades, dealer flows will accelerate the downside.

Regime Assessment

The market remains in a negative gamma regime for the third consecutive day, carrying a Net GEX magnitude of negative 17.1 billion dollars. Dealers are short options, forcing them to sell dips and buy rallies. The VIX sits at 17.16, keeping the day type forecast at high volatility. There is no gamma flip level within the observable chain. However, eight high-impact releases before the open could force massive dealer re-hedging and rewrite the regime entirely.

Critical Pivots

The standard options geometry is anchored to yesterday's SPX close of 7591. The expected move band is plus or minus 82 points, defining a lower bound of 7510 and an upper bound of 7674. Dealer gamma resistance rests at the 7750 Call Wall, while dealer gamma support is parked at the 7500 Put Wall. ES futures currently sit 144 points above the Put Wall and 106 points from the Call Wall. Neither wall is under immediate threat from the expected move. The overnight gap has already pushed ES past R1 at 7609 and R2 at 7627. If the gap fades, it reprices the floor to 92 points.

Overnight Drivers

Overnight price action was dictated by a bond-market shock, with the 10-year yield approaching 4.95 percent and markets pricing a 70 percent chance of a 25 basis point Fed hike next week. Cross-asset reads show ES up 0.6 percent, VIX down 3.82 percent, and the 10-year yield surging 12 basis points. Sector-wise, Communication Services and Industrials led, while rate-sensitive Utilities and Real Estate lagged heavily.

Risk Radar

Today's primary threat is the 08:30 ET CPI print, marking a 5 out of 5 calendar risk score. CPI drops at 08:30. Tell me in the comments — does this print trigger a gap fill, or does the overnight rally hold? An upside surprise forces aggressive dealer selling, while a cool print could extend momentum toward the Call Wall.

Conditions Read

This environment is consistent with defined-risk directional structures. Selling premium in this regime is picking up pennies in front of a steamroller. A breakdown below 7562 invalidates the upside continuation thesis.

Bottom Line

We are in Day 3 of negative gamma heading into a highly volatile data drop. The morning inflation print will dictate the intraday flow.

Sign Off

The data drops before the open. Let the market show its hand first. Levels set. Bias defined. Good luck out there.
