Fiserv, Inc. is currently running 32.8% annualised volatility over the last 21 sessions. Measured against FISV's own 13 years of daily returns rather than a market-wide average, that is the 83rd percentile — elevated for this stock, against a typical reading of 20.2%. 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.

FISV is trading -80.2% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -14.2%, and the deepest was -74.9% in 2025. 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 -18.5% from its 200-day moving average. Against every other day in its history, that gap ranks at the 9th percentile — a narrower gap than it typically runs. Over the past year FISV closed higher on 51% of sessions, and it is currently 5 sessions into a falling streak.

On September specifically: over 13 years of records, FISV finished the month higher 5 of 13 times, with a median return of -2.1% and an average of -2.2%. Its strongest month historically has been November at +4.9% on average, its weakest October at -2.6%. 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: FISV has opened more than 2% away from the prior close in 92 of 3,266 sessions (2.8% of the time), with the largest gaps running +7.1% and -7.8%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

Across the last 3 dated reports on file, FISV moved an average of 1.8% in the session after earnings, closing higher 0 of those 3 times, with a median move of -2.0% and a largest of -2.3%.

All figures computed from 3,268 daily closes between 2013-09-20 and 2026-09-18, split-adjusted, recomputed daily. Percentiles are against FISV's own 13-year history, not a peer group or index.
