Trimble Inc. is currently running 27.2% annualised volatility over the last 21 sessions. Measured against TRMB's own 13 years of daily returns rather than a market-wide average, that is the 48th percentile — close to its own typical level, against a typical reading of 27.7%. 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.

TRMB is trading -38.4% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -31.4%, and the deepest was -53.8% in 2020. The current drawdown is already deeper than this stock's typical annual low point, which puts it in the part of its range where past recoveries began — and where past declines also continued.

Price sits -4.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 35th percentile — close to the gap it normally carries. Over the past year TRMB closed higher on 51% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 14 years of records, TRMB finished the month higher 8 of 14 times, with a median return of +1.5% and an average of +1.7%. Its strongest month historically has been November at +4.4% on average, its weakest September at -2.0%. 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: TRMB has opened more than 2% away from the prior close in 194 of 3,268 sessions (5.9% of the time), with the largest gaps running +12.0% and -14.6%. 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, TRMB moved an average of 3.7% in the session after earnings, closing higher 1 of those 3 times, with a median move of -4.2% and a largest of -4.7%.
