Knight-Swift Transportation Holdings Inc. is currently running 28.4% annualised volatility over the last 21 sessions. Measured against KNX's own 13 years of daily returns rather than a market-wide average, that is the 36th percentile — on the quiet side for this stock, against a typical reading of 31.7%. 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.

KNX is trading -23.6% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -26.3%, and the deepest was -55.4% in 2015. 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 -3.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 31st percentile — close to the gap it normally carries. Over the past year KNX closed higher on 47% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, KNX finished the month higher 8 of 13 times, with a median return of +2.5% and an average of +3.4%. Its strongest month historically has been November at +7.1% on average, its weakest December 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: KNX has opened more than 2% away from the prior close in 193 of 3,267 sessions (5.9% of the time), with the largest gaps running +10.9% and -15.6%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,268 daily closes between 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against KNX's own 13-year history, not a peer group or index.
