CGI Inc. is currently running 46.6% annualised volatility over the last 21 sessions. Measured against GIB's own 13 years of daily returns rather than a market-wide average, that is the 98th percentile — an extreme by its own standards, against a typical reading of 20.6%. 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.

GIB is trading -41.1% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -14.6%, and the deepest was -45.8% 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 -1.6% from its 200-day moving average. Against every other day in its history, that gap ranks at the 29th percentile — a narrower gap than it typically runs. Over the past year GIB closed higher on 50% of sessions, and it is currently 4 sessions into a rising streak.

On October specifically: over 13 years of records, GIB finished the month higher 6 of 13 times, with a median return of -0.2% and an average of -1.3%. Its strongest month historically has been November at +5.7% on average, its weakest September at -3.3%. 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: GIB has opened more than 2% away from the prior close in 78 of 3,266 sessions (2.4% of the time), with the largest gaps running +8.4% and -9.0%. 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 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against GIB's own 13-year history, not a peer group or index.
