Jack Henry & Associates, Inc. is currently running 43.3% annualised volatility over the last 21 sessions. Measured against JKHY's own 13 years of daily returns rather than a market-wide average, that is the 97th percentile — an extreme by its own standards, against a typical reading of 18.5%.

JKHY is trading -15.9% below its running peak. Across 13 full years on file, its median worst-drawdown-in-a-year was -16.8%, and the deepest was -35.9% in 2026. 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 +15.1% from its 200-day moving average. Against every other day in its history, that gap ranks at the 95th percentile — a wider gap than this stock usually carries. Over the past year JKHY closed higher on 53% of sessions, and it is currently 1 session into a falling streak.

On November specifically: over 13 years of records, JKHY finished the month higher 9 of 13 times, with a median return of +2.7% and an average of +3.0%. Its strongest month historically has been November at +3.0% on average, its weakest September at -3.1%.

Overnight risk is measurable too: JKHY has opened more than 2% away from the prior close in 65 of 3,268 sessions (2.0% of the time), with the largest gaps running +10.4% and -8.9%.

Across the last 4 dated reports on file, JKHY moved an average of 6.1% in the session after earnings, closing higher 2 of those 4 times, with a median move of +1.1% and a largest of +10.8%.

All figures computed from 3,269 daily closes between 2013-11-06 and 2026-11-05, split-adjusted, recomputed daily. Percentiles are against JKHY's own 13-year history, not a peer group or index.
