2026-05-29 – 2026-11-13 · measured on each week's last regular-session close
Of CBRS's 25 settled weeks, 16 (64.0%) finished inside ±1σ on the week's last close. 2 (8.0%) finished at or above +1σ and 7 (28.0%) at or below −1σ. A normal distribution puts 68.3% inside and about 15.9% beyond each side. With only 25 weeks on record, the gap from theory is too early to read.
This week's band of ±15.3% is 1.20× the symbol's median width of ±12.8% and ranks #11 widest of 184 tracked symbols. That is close to its usual width.
The week that finished furthest from its anchor closed 2026-10-16 at −2.61σ. The most recent finish outside was 2026-11-06 (−1.44σ), followed by 1 straight weeks inside.
Past shares do not predict next week. A week that broke the band intraday but closed back inside counts as inside. The universe-wide measurement and its method are in the weekly ±1σ coverage study.

Close-to-close price changes, excluding dividends and costs. — means future or unavailable. Predictive value is still under validation.
Dealer gamma stacked at each strike. The dashed lines are this week's ±1σ edges, so whether a thick strike and a band edge land on the same price is readable in one view.
Hedging leans against the move, so the strikes below tend to hold.
+1σ $125.23 · −1σ $91.95 — outside the published strike window ($98.00–$119.00), so not drawn on the ladder above.
All expirations, strikes within ±10% of spot. Open interest settles once a day, so these levels move on the same cadence as the σ band.
