CACI International Inc. Class A is currently running 33.4% annualised volatility over the last 21 sessions. Measured against CACI's own 13 years of daily returns rather than a market-wide average, that is the 82nd percentile — elevated for this stock, against a typical reading of 22.1%. 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.

CACI is trading -10.6% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -19.3%, and the deepest was -41.4% in 2020. The current pullback is therefore shallower than what this stock gives back in a typical year, which is context worth having before treating it as a dislocation.

Price sits +8.0% 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 CACI closed higher on 50% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, CACI finished the month higher 10 of 13 times, with a median return of +6.3% and an average of +7.1%. Its strongest month historically has been October at +7.1% on average, its weakest December at -3.1%. 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: CACI has opened more than 2% away from the prior close in 99 of 3,267 sessions (3.0% of the time), with the largest gaps running +9.5% and -12.5%. 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 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against CACI's own 13-year history, not a peer group or index.
