Stifel Financial Corporation is currently running 18.2% annualised volatility over the last 21 sessions. Measured against SF's own 13 years of daily returns rather than a market-wide average, that is the 9th percentile — unusually subdued by its own history, against a typical reading of 27.7%. 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.

SF is trading -20.5% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -27.3%, and the deepest was -52.2% 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 -9.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 17th percentile — a narrower gap than it typically runs. Over the past year SF closed higher on 54% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, SF finished the month higher 10 of 13 times, with a median return of +4.5% and an average of +4.1%. Its strongest month historically has been November at +7.2% on average, its weakest March at -5.2%. 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: SF has opened more than 2% away from the prior close in 264 of 3,267 sessions (8.1% of the time), with the largest gaps running +12.4% and -17.6%. 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 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against SF's own 13-year history, not a peer group or index.
