UnitedHealth Group Incorporated is currently running 18.9% annualised volatility over the last 21 sessions. Measured against UNH's own 13 years of daily returns rather than a market-wide average, that is the 34th percentile — on the quiet side for this stock, against a typical reading of 22.2%. 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.

UNH is trading -39.6% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -16.0%, and the deepest was -60.6% in 2025. 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 +6.2% from its 200-day moving average. Against every other day in its history, that gap ranks at the 42nd percentile — close to the gap it normally carries. Over the past year UNH closed higher on 48% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, UNH finished the month higher 8 of 13 times, with a median return of +2.1% and an average of +3.9%. Its strongest month historically has been November at +5.1% on average, its weakest February at -1.2%. 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: UNH has opened more than 2% away from the prior close in 41 of 3,268 sessions (1.3% of the time), with the largest gaps running +9.3% and -6.4%. 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, UNH moved an average of 1.8% in the session after earnings, closing higher 3 of those 3 times, with a median move of +2.3% and a largest of +3.2%.
