Waste Management, Inc. is currently running 13.4% annualised volatility over the last 21 sessions. Measured against WM's own 13 years of daily returns rather than a market-wide average, that is the 36th percentile — on the quiet side for this stock, against a typical reading of 15.2%. 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.

WM is trading -14.5% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -11.2%, and the deepest was -29.9% 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 -5.6% from its 200-day moving average. Against every other day in its history, that gap ranks at the 5th percentile — a narrower gap than it typically runs. Over the past year WM closed higher on 49% of sessions, and it is currently 2 sessions into a rising streak.

On October specifically: over 13 years of records, WM finished the month higher 8 of 13 times, with a median return of +3.7% and an average of +1.8%. Its strongest month historically has been November at +4.7% on average, its weakest September at -2.1%. 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: WM has opened more than 2% away from the prior close in 45 of 3,267 sessions (1.4% of the time), with the largest gaps running +3.7% and -4.6%. 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, WM moved an average of 1.7% in the session after earnings, closing higher 2 of those 3 times, with a median move of +1.9% and a largest of +2.1%.

All figures computed from 3,268 daily closes between 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against WM's own 13-year history, not a peer group or index.
