PPI Shock Absorbed: Markets Pin Near Walls Despite Inflation Blowout

GAMMA BRIEF AI Generated 2026-05-13

Producer prices exploded to 6% year-over-year — nearly double estimates — yet SPY closed the day essentially flat, hugging the 742-743 zone with the composure of a market that either doesn't believe the data or simply doesn't care. That's not strength. That's pinning.

The real story is in the flow: three separate 0DTE call sweeps on SPY near the 738-740 strikes totaling roughly $384M in premium, and a massive $223M call sweep at the 600 strike expiring May 2026 with a 123x vol/OI ratio. Dealers are working overtime to stay hedged, and the gamma structure is holding the tape hostage into the close.

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
