2024-09-06 – 2026-11-13 · measured on each week's last regular-session close
Of GDX's 115 settled weeks, 72 (62.6%) finished inside ±1σ on the week's last close. 26 (22.6%) finished at or above +1σ and 17 (14.8%) 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. Breaks skewed upward: more weeks finished above +1σ than below −1σ.
This week's band of ±5.8% is 1.11× the symbol's median width of ±5.2% and ranks #96 widest of 184 tracked symbols. That is close to its usual width.
The week that finished furthest from its anchor closed 2026-08-07 at +3.72σ. The latest week (2026-11-13) finished outside, at −1.06σ.
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.
