Cintas Corporation is currently running 21.0% annualised volatility over the last 21 sessions. Measured against CTAS's own 13 years of daily returns rather than a market-wide average, that is the 55th percentile — close to its own typical level, against a typical reading of 19.7%. 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.

CTAS is trading -8.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -15.6%, and the deepest was -54.5% 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 +10.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 58th percentile — a somewhat wider gap than its own norm. Over the past year CTAS closed higher on 52% of sessions, and it is currently 6 sessions into a rising streak.

On October specifically: over 14 years of records, CTAS finished the month higher 10 of 14 times, with a median return of +3.3% and an average of +1.7%. Its strongest month historically has been July at +6.9% on average, its weakest March at -1.6%. 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: CTAS has opened more than 2% away from the prior close in 95 of 3,268 sessions (2.9% of the time), with the largest gaps running +17.6% and -13.9%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

Across the last 4 dated reports on file, CTAS moved an average of 3.9% in the session after earnings, closing higher 2 of those 4 times, with a median move of +0.9% and a largest of +6.8%.

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