Gap-up thesis confirmed: SPY holds 775 wall, SPX drives toward 7800 on positive GEX; QQQ outperforms despite AAPL weakness

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.
