SPY pinned between call and put wall as bulls hold slim edge

GAMMA BRIEF AI Generated 2026-08-25

After gapping higher at the open, the S&P 500 ETF spent the session grinding between 763 and 767, unable to push meaningfully above resistance or collapse toward support. The morning's fade thesis got a partial look when SPY dipped to 763.34 intraday, but buyers stepped in and price has since recovered to 765.73 — right back in the center of the tension zone.

NVDA is up 1.79% on the day and QQQ briefly tagged 714, just one dollar below its call wall, suggesting tech is carrying the session while small-caps remain the laggard — IWM has not once challenged 300 today and is sitting below VWAP with a bearish trend bias score of -21. Geopolitical noise around Iran, Hormuz shipping conditions, and Canada's retaliatory tariffs is running in the background, but so far the tape is shrugging it off.

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.
