IES Holdings Inc. is currently running 48.5% annualised volatility over the last 21 sessions. Measured against IESC's own 13 years of daily returns rather than a market-wide average, that is the 65th percentile — a little above its own norm, against a typical reading of 42.1%. 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.

IESC is trading -64.0% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -29.6%, and the deepest was -52.8% 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 -45.8% from its 200-day moving average. Against every other day in its history, that gap ranks at the 0th percentile — a narrower gap than it typically runs. Over the past year IESC closed higher on 53% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 14 years of records, IESC finished the month higher 5 of 14 times, with a median return of -3.3% and an average of -1.7%. Its strongest month historically has been November at +8.3% on average, its weakest October at -1.7%. 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: IESC has opened more than 2% away from the prior close in 437 of 3,266 sessions (13.4% of the time), with the largest gaps running +20.5% and -49.3%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,267 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against IESC's own 13-year history, not a peer group or index.
