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 lean weighs GEX structure, options flow, and macro signals, and may point the opposite direction when flow or positioning disagrees with the tape.
