United Rentals, Inc. is currently running 30.5% annualised volatility over the last 21 sessions. Measured against URI's own 13 years of daily returns rather than a market-wide average, that is the 30th percentile — on the quiet side for this stock, against a typical reading of 35.0%. 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.

URI is trading -9.3% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -31.5%, and the deepest was -58.5% 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 +10.9% from its 200-day moving average. Against every other day in its history, that gap ranks at the 54th percentile — close to the gap it normally carries. Over the past year URI closed higher on 52% of sessions, and it is currently 4 sessions into a rising streak.

On October specifically: over 13 years of records, URI finished the month higher 9 of 13 times, with a median return of +2.1% and an average of +2.1%. Its strongest month historically has been November at +7.8% on average, its weakest March at -1.9%. 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: URI has opened more than 2% away from the prior close in 217 of 3,267 sessions (6.6% of the time), with the largest gaps running +8.1% and -7.0%. 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, URI moved an average of 6.3% in the session after earnings, closing higher 2 of those 3 times, with a median move of +2.2% and a largest of -8.9%.

All figures computed from 3,268 daily closes between 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against URI's own 13-year history, not a peer group or index.
