Amcor plc is currently running 21.1% annualised volatility over the last 21 sessions. Measured against AMCR's own 7 years of daily returns rather than a market-wide average, that is the 31st percentile — on the quiet side for this stock, against a typical reading of 24.6%. 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.

AMCR is trading -38.1% below its running peak. Across 6 full years on file, its median worst-drawdown-in-a-year was -22.9%, and the deepest was -46.3% in 2020. 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 -2.5% from its 200-day moving average. Against every other day in its history, that gap ranks at the 43rd percentile — close to the gap it normally carries. Over the past year AMCR closed higher on 46% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 7 years of records, AMCR finished the month higher 2 of 7 times, with a median return of -1.8% and an average of -1.2%. Its strongest month historically has been November at +4.5% on average, its weakest September at -4.5%. 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: AMCR has opened more than 2% away from the prior close in 106 of 1,839 sessions (5.8% of the time), with the largest gaps running +9.1% and -8.1%. 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, AMCR moved an average of 1.5% in the session after earnings, closing higher 1 of those 3 times, with a median move of -0.2% and a largest of +3.4%.
