Alamos Gold Inc. Class A is currently running 39.9% annualised volatility over the last 21 sessions. Measured against AGI's own 11 years of daily returns rather than a market-wide average, that is the 39th percentile — on the quiet side for this stock, against a typical reading of 43.7%. 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.

AGI is trading -41.6% below its running peak. Across 10 full years on file, its median worst-drawdown-in-a-year was -30.8%, and the deepest was -55.6% in 2018. 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 -17.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 7th percentile — a narrower gap than it typically runs. Over the past year AGI closed higher on 49% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 11 years of records, AGI finished the month higher 5 of 11 times, with a median return of -1.3% and an average of -1.7%. Its strongest month historically has been March at +6.6% on average, its weakest September at -4.0%. 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: AGI has opened more than 2% away from the prior close in 423 of 2,830 sessions (14.9% of the time), with the largest gaps running +24.4% and -22.1%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 2,831 daily closes between 2015-07-06 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against AGI's own 11-year history, not a peer group or index.
