2024-09-06 – 2026-11-13 · measured on each week's last regular-session close
Of NOW's 115 settled weeks, 71 (61.7%) finished inside ±1σ on the week's last close. 21 (18.3%) finished at or above +1σ and 23 (20.0%) at or below −1σ. A normal distribution puts 68.3% inside and about 15.9% beyond each side. Given 115 weeks, the gap from theory is within what chance alone produces.
This week's band of ±6.6% is 1.31× the symbol's median width of ±5.0% and ranks #87 widest of 184 tracked symbols. The options market is pricing a larger move than usual; check whether an earnings release or similar event falls inside the week.
The week that finished furthest from its anchor closed 2026-05-29 at +2.85σ. The most recent finish outside was 2026-10-30 (−2.65σ), 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 runs with the move, so levels break faster than they 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.
