Genuine Parts Company is currently running 22.3% annualised volatility over the last 21 sessions. Measured against GPC's own 13 years of daily returns rather than a market-wide average, that is the 59th percentile — close to its own typical level, against a typical reading of 20.5%. 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.

GPC is trading -29.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -20.6%, and the deepest was -52.3% 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 +9.6% from its 200-day moving average. Against every other day in its history, that gap ranks at the 80th percentile — a somewhat wider gap than its own norm. Over the past year GPC closed higher on 49% of sessions, and it is currently 5 sessions into a rising streak.

On October specifically: over 14 years of records, GPC finished the month higher 6 of 14 times, with a median return of -0.7% and an average of -0.2%. Its strongest month historically has been November at +4.1% on average, its weakest March at -2.1%. 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: GPC has opened more than 2% away from the prior close in 98 of 3,268 sessions (3.0% of the time), with the largest gaps running +7.3% and -8.4%. 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, GPC moved an average of 2.5% in the session after earnings, closing higher 1 of those 3 times, with a median move of -2.5% and a largest of -4.3%.
