RBC Bearings Incorporated is currently running 28.2% annualised volatility over the last 21 sessions. Measured against RBC's own 13 years of daily returns rather than a market-wide average, that is the 60th percentile — close to its own typical level, against a typical reading of 25.6%. 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.

RBC is trading -22.4% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -21.3%, and the deepest was -55.1% in 2020. 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 -8.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 11th percentile — a narrower gap than it typically runs. Over the past year RBC closed higher on 55% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, RBC finished the month higher 7 of 13 times, with a median return of +1.3% and an average of +3.7%. Its strongest month historically has been November at +7.2% on average, its weakest September at -1.6%. 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: RBC has opened more than 2% away from the prior close in 128 of 3,266 sessions (3.9% of the time), with the largest gaps running +13.3% and -18.3%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,267 daily closes between 2013-10-14 and 2026-10-09, split-adjusted, recomputed daily. Percentiles are against RBC's own 13-year history, not a peer group or index.
