Centene Corporation is currently running 30.9% annualised volatility over the last 21 sessions. Measured against CNC's own 13 years of daily returns rather than a market-wide average, that is the 50th percentile — close to its own typical level, against a typical reading of 30.9%. 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.

CNC is trading -28.8% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -28.3%, and the deepest was -61.7% 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 +29.1% from its 200-day moving average. Against every other day in its history, that gap ranks at the 91st percentile — a wider gap than this stock usually carries. Over the past year CNC closed higher on 53% of sessions, and it is currently 4 sessions into a rising streak.

On October specifically: over 14 years of records, CNC finished the month higher 7 of 14 times, with a median return of +0.0% and an average of +2.6%. Its strongest month historically has been May at +5.4% on average, its weakest July at -3.2%. 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: CNC has opened more than 2% away from the prior close in 151 of 3,268 sessions (4.6% of the time), with the largest gaps running +7.6% and -10.5%. 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, CNC moved an average of 3.6% in the session after earnings, closing higher 1 of those 3 times, with a median move of -1.4% and a largest of +7.8%.
