Tech cracks, VIX spikes 30%, but small caps quietly hold the line

GAMMA BRIEF AI Generated 2026-10-24

It was a week where the Nasdaq gave back ground in a hurry — QQQ shed 3.24% while the VIX exploded nearly 30% higher to close the week. The message from the options market was unambiguous: hedges were being bought, not sold, and dealers were scrambling to manage a rapidly shifting gamma landscape.

Yet underneath the carnage in mega-cap tech, something interesting happened. IWM finished the week fractionally green at +0.24%, and TSLA and AAPL posted positive returns even as NVDA, MSFT, and AMZN all declined. The divergence between small caps and large-cap tech is the story of this week — and likely the setup for the next.

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
