Aptiv PLC is currently running 28.6% annualised volatility over the last 21 sessions. Measured against APTV's own 13 years of daily returns rather than a market-wide average, that is the 44th percentile — close to its own typical level, against a typical reading of 30.4%. 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.

APTV is trading -70.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -30.8%, and the deepest was -65.2% 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 -24.3% from its 200-day moving average. Against every other day in its history, that gap ranks at the 7th percentile — a narrower gap than it typically runs. Over the past year APTV closed higher on 49% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, APTV finished the month higher 7 of 13 times, with a median return of +0.5% and an average of -0.2%. Its strongest month historically has been May at +3.8% on average, its weakest March at -4.4%. 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: APTV has opened more than 2% away from the prior close in 250 of 3,267 sessions (7.7% of the time), with the largest gaps running +9.5% and -11.2%. 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, APTV moved an average of 2.1% in the session after earnings, closing higher 2 of those 3 times, with a median move of +0.4% and a largest of +3.9%.
