Acuity Inc. is currently running 33.6% annualised volatility over the last 21 sessions. Measured against AYI's own 13 years of daily returns rather than a market-wide average, that is the 64th percentile — a little above its own norm, against a typical reading of 28.9%. 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.

AYI is trading -19.4% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -26.8%, and the deepest was -50.2% 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 -3.0% from its 200-day moving average. Against every other day in its history, that gap ranks at the 38th percentile — close to the gap it normally carries. Over the past year AYI closed higher on 54% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, AYI finished the month higher 7 of 13 times, with a median return of +0.4% and an average of +1.2%. Its strongest month historically has been June at +5.7% on average, its weakest April at -2.5%. 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: AYI has opened more than 2% away from the prior close in 139 of 3,267 sessions (4.3% of the time), with the largest gaps running +9.2% and -19.1%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,268 daily closes between 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against AYI's own 13-year history, not a peer group or index.
