Air Products and Chemicals, Inc. is currently running 18.2% annualised volatility over the last 21 sessions. Measured against APD's own 13 years of daily returns rather than a market-wide average, that is the 41st 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.

APD is trading -16.8% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -18.4%, and the deepest was -31.7% in 2025. 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 -1.8% from its 200-day moving average. Against every other day in its history, that gap ranks at the 28th percentile — a narrower gap than it typically runs. Over the past year APD closed higher on 47% of sessions, and it is currently 2 sessions into a rising streak.

On October specifically: over 13 years of records, APD finished the month higher 7 of 13 times, with a median return of +1.2% and an average of +1.3%. Its strongest month historically has been November at +4.7% on average, its weakest September 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: APD has opened more than 2% away from the prior close in 72 of 3,264 sessions (2.2% of the time), with the largest gaps running +5.3% and -9.4%. 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, APD moved an average of 0.8% in the session after earnings, closing higher 1 of those 3 times, with a median move of -0.1% and a largest of +2.0%.

All figures computed from 3,265 daily closes between 2013-10-14 and 2026-10-09, split-adjusted, recomputed daily. Percentiles are against APD's own 13-year history, not a peer group or index.
