Jabil Inc. is currently running 43.4% annualised volatility over the last 21 sessions. Measured against JBL's own 13 years of daily returns rather than a market-wide average, that is the 79th percentile — elevated for this stock, against a typical reading of 31.1%. 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.

JBL is trading -17.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -28.0%, and the deepest was -57.2% 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 +4.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 39th percentile — close to the gap it normally carries. Over the past year JBL closed higher on 54% of sessions, and it is currently 3 sessions into a rising streak.

On October specifically: over 13 years of records, JBL finished the month higher 6 of 13 times, with a median return of +0.0% and an average of +0.3%. Its strongest month historically has been May at +5.9% on average, its weakest January at -0.2%. 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: JBL has opened more than 2% away from the prior close in 228 of 3,267 sessions (7.0% of the time), with the largest gaps running +14.5% and -9.7%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

Across the last 4 dated reports on file, JBL moved an average of 2.4% in the session after earnings, closing higher 2 of those 4 times, with a median move of +1.8% and a largest of +3.7%.

All figures computed from 3,268 daily closes between 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against JBL's own 13-year history, not a peer group or index.
