SPY Sandwiched Between GEX Walls With ISM Due at 10:00

GAMMA BRIEF AI Generated 2026-06-01

Futures are essentially flat this morning — /ES last at 7608.75, SPY pre-market last at 757.91, barely unchanged versus Friday's close. The overnight range was narrow, and the tape is in no hurry ahead of a consequential 10:00 ET ISM Manufacturing print that could set the tone for the first trading week of June.

The options structure tells you exactly where the battlefield sits: SPY is wedged between a 755 put wall and a 760 call wall, with QQQ practically touching its own 740 call wall at the pre-market open. With 71% of SPY volume tied to 0DTE contracts and no unusual options activity above $50M, this is a session where the first macro catalyst — ISM at 10:00 — will likely determine which wall breaks first.

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.
