BorgWarner Inc. is currently running 37.6% annualised volatility over the last 21 sessions. Measured against BWA's own 13 years of daily returns rather than a market-wide average, that is the 76th percentile — elevated for this stock, against a typical reading of 30.3%. 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.

BWA is trading -21.4% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -31.0%, and the deepest was -55.1% 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 +1.0% from its 200-day moving average. Against every other day in its history, that gap ranks at the 50th percentile — close to the gap it normally carries. Over the past year BWA closed higher on 49% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, BWA finished the month higher 8 of 13 times, with a median return of +1.3% and an average of +0.9%. Its strongest month historically has been May at +4.7% on average, its weakest June at -3.5%. 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: BWA has opened more than 2% away from the prior close in 225 of 3,267 sessions (6.9% of the time), with the largest gaps running +10.0% and -13.0%. 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, BWA moved an average of 1.5% in the session after earnings, closing higher 1 of those 3 times, with a median move of -1.5% and a largest of -2.5%.

All figures computed from 3,268 daily closes between 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against BWA's own 13-year history, not a peer group or index.
