United Therapeutics Corporation is currently running 22.9% annualised volatility over the last 21 sessions. Measured against UTHR's own 13 years of daily returns rather than a market-wide average, that is the 21st percentile — unusually subdued by its own history, against a typical reading of 29.9%. 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.

UTHR is trading -16.2% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -29.5%, and the deepest was -41.1% in 2019. 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 -5.2% from its 200-day moving average. Against every other day in its history, that gap ranks at the 27th percentile — a narrower gap than it typically runs. Over the past year UTHR closed higher on 47% of sessions, and it is currently 1 session into a rising streak.

On September specifically: over 13 years of records, UTHR finished the month higher 4 of 13 times, with a median return of -3.1% and an average of -2.5%. Its strongest month historically has been October at +5.8% on average, its weakest September at -2.5%. 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: UTHR has opened more than 2% away from the prior close in 124 of 3,267 sessions (3.8% of the time), with the largest gaps running +51.0% and -12.9%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,268 daily closes between 2013-09-23 and 2026-09-21, split-adjusted, recomputed daily. Percentiles are against UTHR's own 13-year history, not a peer group or index.
