Henry Schein, Inc. is currently running 24.9% annualised volatility over the last 21 sessions. Measured against HSIC's own 13 years of daily returns rather than a market-wide average, that is the 63rd percentile — a little above its own norm, against a typical reading of 22.3%. 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.

HSIC is trading -5.3% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -20.3%, and the deepest was -40.9% 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 +8.2% from its 200-day moving average. Against every other day in its history, that gap ranks at the 74th percentile — a somewhat wider gap than its own norm. Over the past year HSIC closed higher on 52% of sessions, and it is currently 4 sessions into a rising streak.

On October specifically: over 14 years of records, HSIC finished the month higher 6 of 14 times, with a median return of -1.6% and an average of -0.2%. Its strongest month historically has been November at +4.7% on average, its weakest August 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: HSIC has opened more than 2% away from the prior close in 113 of 3,267 sessions (3.5% of the time), with the largest gaps running +5.2% and -10.6%. 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, HSIC moved an average of 1.6% in the session after earnings, closing higher 1 of those 3 times, with a median move of -1.7% and a largest of -2.6%.

All figures computed from 3,269 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against HSIC's own 13-year history, not a peer group or index.
