Celanese Corporation is currently running 41.4% annualised volatility over the last 21 sessions. Measured against CE's own 13 years of daily returns rather than a market-wide average, that is the 81st percentile — elevated for this stock, against a typical reading of 27.9%. 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.

CE is trading -74.1% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -24.6%, and the deepest was -61.0% 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 -12.3% from its 200-day moving average. Against every other day in its history, that gap ranks at the 19th percentile — a narrower gap than it typically runs. Over the past year CE closed higher on 49% of sessions, and it is currently 2 sessions into a rising streak.

On October specifically: over 13 years of records, CE finished the month higher 8 of 13 times, with a median return of +2.0% and an average of +1.1%. Its strongest month historically has been April at +3.7% on average, its weakest June 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: CE has opened more than 2% away from the prior close in 191 of 3,266 sessions (5.8% of the time), with the largest gaps running +6.8% and -8.0%. 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, CE moved an average of 6.5% in the session after earnings, closing higher 0 of those 3 times, with a median move of -7.6% and a largest of -9.8%.

All figures computed from 3,267 daily closes between 2013-10-14 and 2026-10-09, split-adjusted, recomputed daily. Percentiles are against CE's own 13-year history, not a peer group or index.
