Charter Communications, Inc. is currently running 66.2% annualised volatility over the last 21 sessions. Measured against CHTR's own 13 years of daily returns rather than a market-wide average, that is the 97th percentile — an extreme by its own standards, against a typical reading of 27.0%. 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.

CHTR is trading -82.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -24.4%, and the deepest was -54.1% 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 -21.6% from its 200-day moving average. Against every other day in its history, that gap ranks at the 13th percentile — a narrower gap than it typically runs. Over the past year CHTR closed higher on 49% of sessions, and it is currently 2 sessions into a falling streak.

On September specifically: over 14 years of records, CHTR finished the month higher 7 of 14 times, with a median return of -0.6% and an average of -3.0%. Its strongest month historically has been August at +2.9% on average, its weakest September at -3.0%. 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: CHTR has opened more than 2% away from the prior close in 107 of 3,268 sessions (3.3% of the time), with the largest gaps running +7.7% and -7.7%. 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, CHTR moved an average of 4.0% in the session after earnings, closing higher 2 of those 3 times, with a median move of +3.4% and a largest of +5.2%.
