2024-09-06 – 2026-11-13 · measured on each week's last regular-session close
Of XLV's 112 settled weeks, 79 (70.5%) finished inside ±1σ on the week's last close. 16 (14.3%) finished at or above +1σ and 17 (15.2%) at or below −1σ. A normal distribution puts 68.3% inside and about 15.9% beyond each side. Given 112 weeks, the gap from theory is within what chance alone produces.
This week's band of ±2.6% is 1.23× the symbol's median width of ±2.1% and ranks #174 widest of 184 tracked symbols. That is close to its usual width.
The week that finished furthest from its anchor closed 2024-11-15 at −3.78σ. The most recent finish outside was 2026-10-30 (+1.18σ), followed by 2 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.
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.
