Jacobs Solutions Inc. is currently running 21.2% annualised volatility over the last 21 sessions. Measured against J's own 13 years of daily returns rather than a market-wide average, that is the 39th percentile — on the quiet side for this stock, against a typical reading of 23.8%. 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.

J is trading -15.9% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -22.9%, and the deepest was -39.8% in 2014. 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 +4.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 52nd percentile — close to the gap it normally carries. Over the past year J closed higher on 50% of sessions, and it is currently 2 sessions into a rising streak.

On October specifically: over 13 years of records, J finished the month higher 9 of 13 times, with a median return of +2.7% and an average of +2.3%. Its strongest month historically has been August at +3.3% on average, its weakest December at -2.2%. 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: J has opened more than 2% away from the prior close in 119 of 3,266 sessions (3.6% of the time), with the largest gaps running +8.2% and -21.0%. 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 2013-10-14 and 2026-10-09, split-adjusted, recomputed daily. Percentiles are against J's own 13-year history, not a peer group or index.
