Globus Medical Inc. Class A is currently running 29.1% annualised volatility over the last 21 sessions. Measured against GMED's own 13 years of daily returns rather than a market-wide average, that is the 50th percentile — close to its own typical level, against a typical reading of 28.9%. 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.

GMED is trading -24.6% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -27.2%, and the deepest was -45.0% 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 -11.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 15th percentile — a narrower gap than it typically runs. Over the past year GMED closed higher on 47% of sessions, and it is currently 1 session into a rising streak.

On October specifically: over 13 years of records, GMED finished the month higher 9 of 13 times, with a median return of +4.7% and an average of +3.6%. Its strongest month historically has been November at +8.6% on average, its weakest September at -3.1%. 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: GMED has opened more than 2% away from the prior close in 192 of 3,266 sessions (5.9% of the time), with the largest gaps running +17.5% and -13.0%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,267 daily closes between 2013-10-14 and 2026-10-09, split-adjusted, recomputed daily. Percentiles are against GMED's own 13-year history, not a peer group or index.
