IES Holdings Inc. is currently running 56.4% 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 80th percentile — elevated for this stock, 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 -56.7% 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 -35.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 1st percentile — a narrower gap than it typically runs. Over the past year IESC closed higher on 54% of sessions, and it is currently 3 sessions into a rising streak.

On October specifically: over 13 years of records, IESC finished the month higher 6 of 13 times, with a median return of -0.5% and an average of -0.0%. Its strongest month historically has been November at +8.3% on average, its weakest March at -0.1%. 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: IESC has opened more than 2% away from the prior close in 438 of 3,265 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 3,266 daily closes between 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against IESC's own 13-year history, not a peer group or index.
