XLF gamma levels
From the closing options book · September 4, 2026
XLF's closing options book on September 4, 2026 carried −$638K of net dealer gamma spread across 5 expirations and 107 contracts. The sign is negative, so hedging runs with the move rather than against it.
The heaviest call-side strike sits at 58 and the heaviest put-side strike at 57, a band 1.7% wide. XLF has averaged 1.13% between its high and its low over the last 89 sessions, which makes the full width of that band about 1.5 average sessions of travel. It closed above the call wall entirely.
XLF closed at 58.10 — 0.2% above the call wall and 1.9% above the put wall. The call side is the nearer of the two at 0.2% 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.
The gamma flip is at 50, 14% below the close. Crossing it is the single change that most alters how the book behaves, because it inverts the direction dealer hedging pushes — so it matters more than its distance suggests.
XLF's apex — the strike carrying the most gamma in absolute terms — is 57, 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 3 different strikes, and its put wall has printed 3 different strikes. Walls that stay put and walls that migrate every session are different objects, and the difference shows up here before it shows up in price.
