Mueller Industries Inc. is currently running 30.6% annualised volatility over the last 21 sessions. Measured against MLI'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 26.6%. 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.

MLI is trading -13.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -24.5%, and the deepest was -46.2% in 2020. The current pullback is therefore shallower than what this stock gives back in a typical year, which is context worth having before treating it as a dislocation.

Price sits -2.8% from its 200-day moving average. Against every other day in its history, that gap ranks at the 24th percentile — a narrower gap than it typically runs. Over the past year MLI closed higher on 56% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 14 years of records, MLI finished the month higher 10 of 14 times, with a median return of +6.0% and an average of +5.2%. Its strongest month historically has been July at +6.2% on average, its weakest March at -3.5%. 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: MLI has opened more than 2% away from the prior close in 163 of 3,268 sessions (5.0% of the time), with the largest gaps running +11.3% and -14.8%. 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 MLI's own 13-year history, not a peer group or index.
