Encompass Health Corporation is currently running 36.1% annualised volatility over the last 21 sessions. Measured against EHC's own 13 years of daily returns rather than a market-wide average, that is the 88th percentile — elevated for this stock, against a typical reading of 23.7%. 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.

EHC is at its running peak. Across 12 full years on file its median worst-drawdown-in-a-year was -17.5%, with the deepest at -39.5% in 2020 — so highs have historically been given back before they were extended.

Price sits +16.3% from its 200-day moving average. Against every other day in its history, that gap ranks at the 85th percentile — a wider gap than this stock usually carries. Over the past year EHC closed higher on 47% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 14 years of records, EHC finished the month higher 6 of 14 times, with a median return of -1.0% and an average of -1.1%. Its strongest month historically has been April at +6.7% on average, its weakest December at -2.2%. 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: EHC has opened more than 2% away from the prior close in 113 of 3,268 sessions (3.5% of the time), with the largest gaps running +10.9% and -17.1%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,269 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against EHC's own 13-year history, not a peer group or index.
