SPY stalls at 750 call wall; NVDA $323M sweep cluster rewrites tomorrow's tech setup

GAMMA BRIEF AI Generated 2026-05-14

SPY reached as high as 749.53 today — just 47 cents below the 750 call wall — before fading to close at 747.47, unable to clear the ceiling flagged in the midday brief. The range told the real story: a 5.97-point intraday swing from 743.56 to 749.53, with the close sitting in the upper third, suggesting the bulls absorbed the day's selling but couldn't punch through the wall.

Meanwhile, NVDA attracted over $323M in fresh call flow across three sweeps at the 232.5, 235, and 230 strikes — all expiring May 15, 2026 — making it the single most aggressively positioned ticker in today's tape. That kind of concentrated, multi-strike call accumulation into a one-month expiry is not noise. Tomorrow, NVDA's behavior near 235 will be the clearest real-time signal for whether mega-cap tech has more upside to give.

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.
