Ecolab Inc. is currently running 27.6% annualised volatility over the last 21 sessions. Measured against ECL's own 13 years of daily returns rather than a market-wide average, that is the 83rd percentile — elevated for this stock, against a typical reading of 17.8%.

ECL is trading -5.6% below its running peak. Across 13 full years on file, its median worst-drawdown-in-a-year was -14.0%, and the deepest was -44.4% in 2022. 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 +7.5% from its 200-day moving average. Against every other day in its history, that gap ranks at the 74th percentile — a somewhat wider gap than its own norm. Over the past year ECL closed higher on 53% of sessions, and it is currently 1 session into a falling streak.

On November specifically: over 13 years of records, ECL finished the month higher 10 of 13 times, with a median return of +3.0% and an average of +3.9%. Its strongest month historically has been November at +3.9% on average, its weakest September at -1.9%.

Overnight risk is measurable too: ECL has opened more than 2% away from the prior close in 84 of 3,268 sessions (2.6% of the time), with the largest gaps running +7.3% and -8.5%.

Across the last 4 dated reports on file, ECL moved an average of 2.9% in the session after earnings, closing higher 3 of those 4 times, with a median move of +1.8% and a largest of -4.0%.

All figures computed from 3,269 daily closes between 2013-11-06 and 2026-11-05, split-adjusted, recomputed daily. Percentiles are against ECL's own 13-year history, not a peer group or index.
