2026-07-24 – 2026-11-13 · measured on each week's last regular-session close
Of SKHY's 17 settled weeks, 12 (70.6%) finished inside ±1σ on the week's last close. 2 (11.8%) finished at or above +1σ and 3 (17.6%) at or below −1σ. A normal distribution puts 68.3% inside and about 15.9% beyond each side. With only 17 weeks on record, the gap from theory is too early to read.
This week's band of ±10.8% is 1.14× the symbol's median width of ±9.4% and ranks #50 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 −3.08σ. The most recent finish outside was 2026-11-06 (−1.45σ), 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 runs with the move, so levels break faster than they hold.
+1σ $146.10 · −1σ $117.57 — outside the published strike window ($120.00–$143.00), 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.
