Telus Corporation is currently running 20.5% annualised volatility over the last 21 sessions. Measured against TU's own 13 years of daily returns rather than a market-wide average, that is the 72nd percentile — a little above its own norm, against a typical reading of 16.4%. 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.

TU is trading -71.2% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -22.0%, and the deepest was -34.5% in 2020. 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 -33.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 0th percentile — a narrower gap than it typically runs. Over the past year TU closed higher on 44% of sessions, and it is currently 3 sessions into a falling streak.

On October specifically: over 13 years of records, TU finished the month higher 7 of 13 times, with a median return of +0.9% and an average of +0.2%. Its strongest month historically has been January at +3.1% on average, its weakest September at -4.2%. 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: TU has opened more than 2% away from the prior close in 97 of 3,267 sessions (3.0% of the time), with the largest gaps running +13.0% and -13.3%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,268 daily closes between 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against TU's own 13-year history, not a peer group or index.
