Huntington Ingalls Industries, Inc. is currently running 23.3% annualised volatility over the last 21 sessions. Measured against HII's own 13 years of daily returns rather than a market-wide average, that is the 52nd percentile — close to its own typical level, against a typical reading of 22.8%. 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.

HII is trading -43.6% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -18.5%, and the deepest was -50.5% 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 -24.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 2nd percentile — a narrower gap than it typically runs. Over the past year HII closed higher on 45% of sessions, and it is currently 3 sessions into a falling streak.

On October specifically: over 13 years of records, HII finished the month higher 11 of 13 times, with a median return of +5.1% and an average of +2.5%. Its strongest month historically has been February at +4.8% on average, its weakest May at -2.9%. 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: HII has opened more than 2% away from the prior close in 102 of 3,267 sessions (3.1% of the time), with the largest gaps running +7.6% and -7.8%. 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, HII moved an average of 4.9% in the session after earnings, closing higher 2 of those 3 times, with a median move of +2.2% and a largest of +9.8%.

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