Novo Nordisk A/S is currently running 35.2% annualised volatility over the last 21 sessions. Measured against NVO's own 13 years of daily returns rather than a market-wide average, that is the 77th percentile — elevated for this stock, against a typical reading of 26.1%. 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.

NVO is trading -74.3% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -18.0%, and the deepest was -50.4% in 2025. The current drawdown is already deeper than this stock's typical annual low point, which puts it in the part of its range where past recoveries began — and where past declines also continued.

Price sits -16.0% 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 NVO closed higher on 45% of sessions, and it is currently 3 sessions into a falling streak.

On October specifically: over 14 years of records, NVO finished the month higher 6 of 14 times, with a median return of -1.6% and an average of -1.3%. Its strongest month historically has been April at +3.5% on average, its weakest September at -3.7%. 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: NVO has opened more than 2% away from the prior close in 249 of 3,268 sessions (7.6% of the time), with the largest gaps running +6.5% and -14.0%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

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