NVDA led, AMZN bled, and VIX quietly exited the building in August.

GAMMA BRIEF AI Generated 2026-09-05

August 2026 closed the book on a month where artificial intelligence conviction and healthcare defensiveness quietly overpowered a consumer sector that couldn't find its footing. NVDA surged 11.48% and XLE ripped 8.96% while AMZN shed nearly 9% and XLU cratered 4.73% — a rotation story that demanded active positioning, not passive drift.

VIX fell 7.28% on the month, compressing premium across the board and rewarding sellers of tail risk who read the macro setup correctly. GammaBrief flagged the vol-crush setup early, and our SPY and QQQ directional models — running 78% and 83% accuracy respectively over the trailing 42 days — kept subscribers on the right side of the dominant moves. Here is the full August 2026 monthly recap.

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.
