CMG closing levels — October 19, 2026. Drawn to scale.

CMG's closing options book on October 19, 2026 carried −$10.9 million of net dealer gamma spread across 5 expirations and 124 contracts. The sign is negative, so hedging runs with the move rather than against it.

The heaviest call-side strike sits at 31 and the heaviest put-side strike at 28, a band 10% wide. CMG has averaged 3.43% between its high and its low over the last 89 sessions, which makes the full width of that band about 2.9 average sessions of travel. It closed in the upper third of that band.

CMG closed at 29.85 — 3.9% below the call wall and 6.2% above the put wall. The call side is the nearer of the two at 3.9% away, which is the only reason it is worth watching more closely than the other. Most levels drawn on a chart are never reached at all, and the distance is what separates them.

CMG's apex — the strike carrying the most gamma in absolute terms — is 28, the same strike as its put wall. When those stack on one level the book is concentrated rather than spread, and that single strike is doing most of the work.

Across the last 10 recorded sessions its call wall has printed 4 different strikes, and its put wall has not moved off 28 once. Walls that stay put and walls that migrate every session are different objects.

What CMG's walls are — and aren't

CMG's book has been recorded on 89 sessions. Its average daily range over that stretch was 3.43% of price. Walls are where dealer hedging is heaviest — positive gamma absorbs moves, negative gamma amplifies them. They are not bounce points, and across our grading they contained price no better than a same-width band around the prior close.
