First Horizon Corporation is currently running 18.7% annualised volatility over the last 21 sessions. Measured against FHN's own 13 years of daily returns rather than a market-wide average, that is the 21st percentile — unusually subdued by its own history, against a typical reading of 25.4%. 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.

FHN is trading -13.6% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -22.9%, and the deepest was -61.1% in 2023. 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 -6.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 20th percentile — a narrower gap than it typically runs. Over the past year FHN closed higher on 55% of sessions, and it is currently 3 sessions into a falling streak.

On October specifically: over 13 years of records, FHN finished the month higher 8 of 13 times, with a median return of +0.2% and an average of +1.6%. Its strongest month historically has been November at +7.3% on average, its weakest March at -5.5%. 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: FHN has opened more than 2% away from the prior close in 189 of 3,267 sessions (5.8% of the time), with the largest gaps running +20.3% and -13.5%. 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 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against FHN's own 13-year history, not a peer group or index.
