Arrow Electronics Inc. is currently running 35.6% annualised volatility over the last 21 sessions. Measured against ARW's own 13 years of daily returns rather than a market-wide average, that is the 84th percentile — elevated for this stock, against a typical reading of 23.9%. 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.

ARW is trading -6.8% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -24.5%, and the deepest was -52.1% 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 +25.5% from its 200-day moving average. Against every other day in its history, that gap ranks at the 92nd percentile — a wider gap than this stock usually carries. Over the past year ARW closed higher on 57% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 14 years of records, ARW finished the month higher 6 of 14 times, with a median return of -0.3% and an average of -1.3%. Its strongest month historically has been November at +3.9% on average, its weakest October at -1.3%. 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: ARW has opened more than 2% away from the prior close in 147 of 3,268 sessions (4.5% of the time), with the largest gaps running +9.2% and -11.6%. 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 ARW's own 13-year history, not a peer group or index.
