Agilent Technologies, Inc. is currently running 31.8% annualised volatility over the last 21 sessions. Measured against A's own 13 years of daily returns rather than a market-wide average, that is the 79th percentile — elevated for this stock, against a typical reading of 24.3%. 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.

A is trading -4.4% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -22.2%, and the deepest was -38.2% 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 +27.9% from its 200-day moving average. Against every other day in its history, that gap ranks at the 99th percentile — a wider gap than this stock usually carries. Over the past year A closed higher on 53% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 14 years of records, A finished the month higher 8 of 14 times, with a median return of +0.9% and an average of +0.1%. Its strongest month historically has been November at +6.5% on average, its weakest February at -2.7%. 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: A has opened more than 2% away from the prior close in 112 of 3,267 sessions (3.4% of the time), with the largest gaps running +10.5% and -26.7%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

Across the last 3 dated reports on file, A moved an average of 3.7% in the session after earnings, closing higher 1 of those 3 times, with a median move of -0.2% and a largest of +9.4%.

All figures computed from 3,268 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against A's own 13-year history, not a peer group or index.
