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

ASTS's closing options book on October 19, 2026 carried −$1.7 million of net dealer gamma spread across 5 expirations and 163 contracts. The sign is negative, so hedging runs with the move rather than against it.

The heaviest call-side strike sits at 46 and the heaviest put-side strike at 40, a band 14% wide. ASTS has averaged 6.75% between its high and its low over the last 88 sessions, which makes the full width of that band about 2.1 average sessions of travel. It closed in the lower third of that band.

ASTS closed at 41.87 — 9.9% below the call wall and 4.5% above the put wall. The put side is the nearer of the two at 4.5% 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.

ASTS's apex — the strike carrying the most gamma in absolute terms — is 40, 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 moved almost every session, and its put wall has printed 3 different strikes. Walls that stay put and walls that migrate every session are different objects.

What ASTS's walls are — and aren't

ASTS's book has been recorded on 88 sessions. Its average daily range over that stretch was 6.75% 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.
