Keysight Technologies, Inc. is currently running 26.6% annualised volatility over the last 21 sessions. Measured against KEYS's own 12 years of daily returns rather than a market-wide average, that is the 48th percentile — close to its own typical level, against a typical reading of 27.3%. 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.

KEYS is trading -4.9% below its running peak. Across 11 full years on file, its median worst-drawdown-in-a-year was -25.8%, and the deepest was -36.7% in 2023. 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 +20.1% from its 200-day moving average. Against every other day in its history, that gap ranks at the 80th percentile — a wider gap than this stock usually carries. Over the past year KEYS closed higher on 57% of sessions, and it is currently 2 sessions into a falling streak.

On October specifically: over 12 years of records, KEYS finished the month higher 9 of 12 times, with a median return of +5.6% and an average of +3.2%. Its strongest month historically has been November at +7.2% on average, its weakest March at -1.4%. 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: KEYS has opened more than 2% away from the prior close in 128 of 3,012 sessions (4.2% of the time), with the largest gaps running +10.9% and -10.0%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

Across the last 4 dated reports on file, KEYS moved an average of 4.7% in the session after earnings, closing higher 1 of those 4 times, with a median move of -1.6% and a largest of -8.6%.

All figures computed from 3,013 daily closes between 2014-10-20 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against KEYS's own 12-year history, not a peer group or index.
