SPY Clears Call Wall Overnight; 0DTE Pin Risk Below Current Levels

GAMMA BRIEF AI Generated 2026-06-15

Stocks are set to open essentially flat Monday after a quiet weekend session, with SPY printing 751.32 pre-market — virtually unchanged from Friday's close. The notable story isn't the overnight move; it's where price is sitting: SPY has pushed above its own 750 call wall, while a U.S.-Iran deal sent oil tumbling and is lifting risk sentiment heading into the open.

Beneath the calm surface, the options structure is more complex. SPY's net GEX is slightly negative at -$1.11B, meaning dealers aren't providing the cushioning support you'd expect in a typical positive-gamma regime. With 0DTE volume running at 75.8% of total SPY flow and max pain sitting at 730 — well below current price — this session has the ingredients for sharper-than-expected intraday moves rather than a quiet drift.

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.
