Humana Inc. is currently running 43.5% annualised volatility over the last 21 sessions. Measured against HUM's own 13 years of daily returns rather than a market-wide average, that is the 85th percentile — elevated for this stock, against a typical reading of 25.3%. 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.

HUM is trading -25.5% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -22.5%, and the deepest was -49.9% in 2024. 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 +40.9% from its 200-day moving average. Against every other day in its history, that gap ranks at the 98th percentile — a wider gap than this stock usually carries. Over the past year HUM closed higher on 54% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, HUM finished the month higher 7 of 13 times, with a median return of +4.2% and an average of +4.3%. Its strongest month historically has been May at +6.5% on average, its weakest January at -3.8%. 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: HUM has opened more than 2% away from the prior close in 103 of 3,268 sessions (3.2% of the time), with the largest gaps running +8.9% and -11.8%. 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, HUM moved an average of 1.8% in the session after earnings, closing higher 2 of those 3 times, with a median move of +1.8% and a largest of -1.8%.

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