Generac Holdings Inc. is currently running 111.9% annualised volatility over the last 21 sessions. Measured against GNRC's own 13 years of daily returns rather than a market-wide average, that is the 99th percentile — an extreme by its own standards, against a typical reading of 36.3%. 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.

GNRC is trading -57.8% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -33.4%, and the deepest was -74.1% in 2022. 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 +1.0% from its 200-day moving average. Against every other day in its history, that gap ranks at the 41st percentile — close to the gap it normally carries. Over the past year GNRC closed higher on 51% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, GNRC finished the month higher 10 of 13 times, with a median return of +7.5% and an average of +3.8%. Its strongest month historically has been June at +7.3% on average, its weakest March at -3.1%. 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: GNRC has opened more than 2% away from the prior close in 257 of 3,267 sessions (7.9% of the time), with the largest gaps running +34.2% 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, GNRC moved an average of 1.5% in the session after earnings, closing higher 1 of those 3 times, with a median move of -0.2% and a largest of +2.8%.
