Hecla Mining is currently running 44.4% annualised volatility over the last 21 sessions. Measured against HL's own 13 years of daily returns rather than a market-wide average, that is the 27th percentile — on the quiet side for this stock, against a typical reading of 55.1%. The distinction matters because a number that looks calm for one stock is turbulent for another, and the absolute figure on its own tells you neither.

HL is trading -49.4% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -48.1%, and the deepest was -57.1% in 2019. The current drawdown is already deeper than this stock's typical annual low point, which puts it in the part of its range where past recoveries began — and where past declines also continued.

Price sits -15.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 26th percentile — a narrower gap than it typically runs. Over the past year HL closed higher on 48% of sessions, and it is currently 3 sessions into a falling streak.

On October specifically: over 14 years of records, HL finished the month higher 8 of 14 times, with a median return of +2.9% and an average of +1.0%. Its strongest month historically has been July at +7.7% on average, its weakest June at -2.6%. Seasonality is a weak signal on its own — a decade is a small sample and regimes change — but it is a real distribution rather than a rule of thumb.

Overnight risk is measurable too: HL has opened more than 2% away from the prior close in 494 of 3,268 sessions (15.1% of the time), with the largest gaps running +13.3% and -9.9%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

Across the last 3 dated reports on file, HL moved an average of 5.2% in the session after earnings, closing higher 3 of those 3 times, with a median move of +6.3% and a largest of +7.7%.

All figures computed from 3,269 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against HL's own 13-year history, not a peer group or index.
