Mettler-Toledo International Inc. is currently running 28.1% annualised volatility over the last 21 sessions. Measured against MTD's own 13 years of daily returns rather than a market-wide average, that is the 69th percentile — a little above its own norm, against a typical reading of 23.6%. 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.

MTD is trading -9.0% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -24.2%, and the deepest was -39.8% in 2023. 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 +17.3% from its 200-day moving average. Against every other day in its history, that gap ranks at the 82nd percentile — a wider gap than this stock usually carries. Over the past year MTD closed higher on 49% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, MTD finished the month higher 9 of 13 times, with a median return of +2.7% and an average of +1.3%. Its strongest month historically has been November at +5.5% on average, its weakest February at -1.5%. 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: MTD has opened more than 2% away from the prior close in 118 of 3,266 sessions (3.6% of the time), with the largest gaps running +9.2% and -10.3%. 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, MTD moved an average of 4.7% in the session after earnings, closing higher 0 of those 3 times, with a median move of -0.7% and a largest of -13.3%.

All figures computed from 3,267 daily closes between 2013-10-14 and 2026-10-09, split-adjusted, recomputed daily. Percentiles are against MTD's own 13-year history, not a peer group or index.
