Brown & Brown, Inc. is currently running 29.3% annualised volatility over the last 21 sessions. Measured against BRO's own 13 years of daily returns rather than a market-wide average, that is the 84th percentile — elevated for this stock, against a typical reading of 18.2%. 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.

BRO is trading -51.0% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -12.4%, and the deepest was -38.6% 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 -10.3% 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 BRO closed higher on 44% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, BRO finished the month higher 4 of 13 times, with a median return of -0.4% and an average of -0.6%. Its strongest month historically has been November at +3.7% on average, its weakest September at -2.7%. 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: BRO has opened more than 2% away from the prior close in 114 of 3,267 sessions (3.5% of the time), with the largest gaps running +10.4% and -12.7%. 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, BRO moved an average of 3.5% in the session after earnings, closing higher 1 of those 3 times, with a median move of -1.3% and a largest of +7.9%.

All figures computed from 3,268 daily closes between 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against BRO's own 13-year history, not a peer group or index.
