General Dynamics Corporation is currently running 20.1% annualised volatility over the last 21 sessions. Measured against GD's own 13 years of daily returns rather than a market-wide average, that is the 62nd percentile — a little above its own norm, against a typical reading of 18.3%. 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.

GD is trading -15.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -12.0%, and the deepest was -43.7% 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 -5.8% from its 200-day moving average. Against every other day in its history, that gap ranks at the 16th percentile — a narrower gap than it typically runs. Over the past year GD closed higher on 50% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 14 years of records, GD finished the month higher 7 of 14 times, with a median return of +0.2% and an average of +1.1%. Its strongest month historically has been July at +3.0% on average, its weakest March at -1.2%. 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: GD has opened more than 2% away from the prior close in 80 of 3,268 sessions (2.4% of the time), with the largest gaps running +5.3% and -6.4%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,269 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against GD's own 13-year history, not a peer group or index.
