AT&T Inc. is currently running 28.1% annualised volatility over the last 21 sessions. Measured against T's own 13 years of daily returns rather than a market-wide average, that is the 87th percentile — elevated for this stock, against a typical reading of 17.7%. 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.

T is trading -29.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -21.0%, and the deepest was -33.4% in 2023. 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 -8.2% from its 200-day moving average. Against every other day in its history, that gap ranks at the 21st percentile — a narrower gap than it typically runs. Over the past year T closed higher on 48% of sessions, and it is currently 3 sessions into a rising streak.

On October specifically: over 14 years of records, T finished the month higher 6 of 14 times, with a median return of -2.8% and an average of -1.9%. Its strongest month historically has been November at +2.3% on average, its weakest October at -1.9%. 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: T has opened more than 2% away from the prior close in 13 of 3,268 sessions (0.4% of the time), with the largest gaps running +27.4% and -4.6%. 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, T moved an average of 2.4% in the session after earnings, closing higher 2 of those 3 times, with a median move of +2.4% and a largest of +4.4%.

All figures computed from 3,269 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against T's own 13-year history, not a peer group or index.
