Universal Health Services, Inc. is currently running 21.4% annualised volatility over the last 21 sessions. Measured against UHS's own 13 years of daily returns rather than a market-wide average, that is the 31st percentile — on the quiet side for this stock, against a typical reading of 25.1%. 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.

UHS is trading -26.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -24.0%, and the deepest was -54.2% 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 -0.1% 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 UHS closed higher on 49% of sessions, and it is currently 4 sessions into a rising streak.

On October specifically: over 13 years of records, UHS finished the month higher 5 of 13 times, with a median return of -0.3% and an average of -0.5%. Its strongest month historically has been July at +5.1% 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: UHS has opened more than 2% away from the prior close in 119 of 3,267 sessions (3.6% of the time), with the largest gaps running +7.2% and -11.6%. 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, UHS moved an average of 7.8% in the session after earnings, closing higher 1 of those 3 times, with a median move of -4.4% and a largest of -10.7%.
