Littelfuse Inc. is currently running 44.0% annualised volatility over the last 21 sessions. Measured against LFUS's own 13 years of daily returns rather than a market-wide average, that is the 91st percentile — an extreme by its own standards, against a typical reading of 27.5%. 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.

LFUS is trading -13.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -22.5%, and the deepest was -45.3% 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 +9.2% from its 200-day moving average. Against every other day in its history, that gap ranks at the 64th percentile — a somewhat wider gap than its own norm. Over the past year LFUS closed higher on 55% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, LFUS finished the month higher 9 of 13 times, with a median return of +6.3% and an average of +3.4%. Its strongest month historically has been May at +4.7% on average, its weakest March at -3.1%. 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: LFUS has opened more than 2% away from the prior close in 155 of 3,266 sessions (4.7% of the time), with the largest gaps running +12.5% and -17.1%. 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 2013-10-14 and 2026-10-09, split-adjusted, recomputed daily. Percentiles are against LFUS's own 13-year history, not a peer group or index.
