Legend Biotech Corporation is currently running 54.0% annualised volatility over the last 21 sessions. Measured against LEGN's own 6 years of daily returns rather than a market-wide average, that is the 58th percentile — close to its own typical level, against a typical reading of 49.6%.

LEGN is trading -70.1% below its running peak. Across 6 full years on file, its median worst-drawdown-in-a-year was -43.8%, and the deepest was -53.6% in 2024. 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 +3.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 62nd percentile — a somewhat wider gap than its own norm. Over the past year LEGN closed higher on 43% of sessions, and it is currently 3 sessions into a rising streak.

On November specifically: over 6 years of records, LEGN finished the month higher 2 of 6 times, with a median return of -3.7% and an average of -1.3%. Its strongest month historically has been June at +15.3% on average, its weakest December at -9.1%.

Overnight risk is measurable too: LEGN has opened more than 2% away from the prior close in 199 of 1,612 sessions (12.3% of the time), with the largest gaps running +7.4% and -6.5%.

All figures computed from 1,613 daily closes between 2020-06-08 and 2026-11-05, split-adjusted, recomputed daily. Percentiles are against LEGN's own 6-year history, not a peer group or index.
