Nordson Corporation is currently running 12.7% annualised volatility over the last 21 sessions. Measured against NDSN's own 13 years of daily returns rather than a market-wide average, that is the 5th percentile — unusually subdued by its own history, against a typical reading of 21.1%. 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.

NDSN is trading -1.4% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -20.9%, and the deepest was -44.4% 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 +14.0% from its 200-day moving average. Against every other day in its history, that gap ranks at the 80th percentile — a wider gap than this stock usually carries. Over the past year NDSN closed higher on 57% of sessions, and it is currently 3 sessions into a rising streak.

On October specifically: over 13 years of records, NDSN finished the month higher 9 of 13 times, with a median return of +1.5% and an average of +2.0%. Its strongest month historically has been November at +3.1% on average, its weakest March at -1.0%. 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: NDSN has opened more than 2% away from the prior close in 93 of 3,267 sessions (2.8% of the time), with the largest gaps running +7.1% and -14.5%. 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, NDSN moved an average of 2.7% in the session after earnings, closing higher 2 of those 3 times, with a median move of +0.9% and a largest of +5.3%.
