Gamma exposure · dealer positioning
as of 2026-11-05

For the 20 Nov 2026 expiry, CBRE's call wall is at 135 and its put wall at 130. Spot (136.35) sits 2.9% above the zero-gamma level (132.5); by the usual heuristic, dealer hedging tends to damp moves above it. Net gamma across the shown strikes is +$0.3M, so dealers are long gamma overall on this expiry. The profile below also covers 1 later expiry.

ATM-straddle implied move to the monthly expiry, % of spot. The line breaks at each roll to a new expiry — either side of a break prices a different contract. Rolled 5×: 22 Jun, 20 Jul, 21 Aug, 17 Sep, 16 Oct.

implied move, % of spotroll to a new expiry

One reading per session, captured nightly after the close, 10 Jun → 5 Nov, over CBOE delayed (~15-min) chains, computed across the full listed chain. Gaps are weekends, holidays and sessions a capture missed; any reading can be absent on a session that was captured, and the series is broken rather than drawn through it.
