Antero Resources Corporation is currently running 35.8% annualised volatility over the last 21 sessions. Measured against AR's own 13 years of daily returns rather than a market-wide average, that is the 31st percentile — on the quiet side for this stock, against a typical reading of 43.1%. 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.

AR is trading -46.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -37.3%, and the deepest was -82.3% in 2019. 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 -1.3% from its 200-day moving average. Against every other day in its history, that gap ranks at the 54th percentile — close to the gap it normally carries. Over the past year AR closed higher on 47% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, AR finished the month higher 6 of 13 times, with a median return of -2.0% and an average of +2.3%. Its strongest month historically has been April at +27.3% on average, its weakest November at -4.7%. 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: AR has opened more than 2% away from the prior close in 346 of 3,266 sessions (10.6% of the time), with the largest gaps running +16.5% and -16.3%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

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