Sterling Infrastructure Inc. is currently running 56.0% annualised volatility over the last 21 sessions. Measured against STRL's own 13 years of daily returns rather than a market-wide average, that is the 70th percentile — a little above its own norm, against a typical reading of 44.5%. 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.

STRL is trading -49.5% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -33.8%, and the deepest was -62.4% in 2015. 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 -9.0% from its 200-day moving average. Against every other day in its history, that gap ranks at the 17th percentile — a narrower gap than it typically runs. Over the past year STRL closed higher on 51% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 14 years of records, STRL finished the month higher 10 of 14 times, with a median return of +5.2% and an average of +5.5%. Its strongest month historically has been May at +12.4% on average, its weakest January at -4.2%. 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: STRL has opened more than 2% away from the prior close in 346 of 3,268 sessions (10.6% of the time), with the largest gaps running +21.1% and -15.3%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

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