Aramark is currently running 17.3% annualised volatility over the last 21 sessions. Measured against ARMK's own 13 years of daily returns rather than a market-wide average, that is the 23rd percentile — unusually subdued by its own history, against a typical reading of 24.7%. 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.

ARMK is trading -12.3% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -19.4%, and the deepest was -72.1% in 2020. The current pullback is therefore shallower than what this stock gives back in a typical year, which is context worth having before treating it as a dislocation.

Price sits +12.0% from its 200-day moving average. Against every other day in its history, that gap ranks at the 77th percentile — a somewhat wider gap than its own norm. Over the past year ARMK closed higher on 51% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 12 years of records, ARMK finished the month higher 8 of 12 times, with a median return of +1.9% and an average of +1.9%. Its strongest month historically has been May at +4.3% on average, its weakest March at -3.2%. 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: ARMK has opened more than 2% away from the prior close in 190 of 3,226 sessions (5.9% of the time), with the largest gaps running +13.2% and -18.9%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,227 daily closes between 2013-12-12 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against ARMK's own 13-year history, not a peer group or index.
