Amphenol Corporation is currently running 49.3% annualised volatility over the last 21 sessions. Measured against APH's own 13 years of daily returns rather than a market-wide average, that is the 94th percentile — an extreme by its own standards, against a typical reading of 21.0%.

APH is trading -12.3% below its running peak. Across 13 full years on file, its median worst-drawdown-in-a-year was -18.6%, and the deepest was -38.8% 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 +3.5% from its 200-day moving average. Against every other day in its history, that gap ranks at the 28th percentile — a narrower gap than it typically runs. Over the past year APH closed higher on 49% of sessions, and it is currently 2 sessions into a falling streak.

On November specifically: over 13 years of records, APH finished the month higher 10 of 13 times, with a median return of +4.5% and an average of +4.5%. Its strongest month historically has been November at +4.5% on average, its weakest December at -0.2%.

Overnight risk is measurable too: APH has opened more than 2% away from the prior close in 109 of 3,268 sessions (3.3% of the time), with the largest gaps running +21.9% and -12.0%.

Across the last 4 dated reports on file, APH moved an average of 2.6% in the session after earnings, closing higher 2 of those 4 times, with a median move of +0.9% and a largest of +6.6%.

All figures computed from 3,269 daily closes between 2013-11-06 and 2026-11-05, split-adjusted, recomputed daily. Percentiles are against APH's own 13-year history, not a peer group or index.
