Marvell Technology Inc. is currently running 46.4% annualised volatility over the last 21 sessions. Measured against MRVL's own 13 years of daily returns rather than a market-wide average, that is the 62nd percentile — a little above its own norm, against a typical reading of 41.0%. 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.

MRVL is trading -16.5% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -31.0%, and the deepest was -61.3% in 2025. 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 +51.8% from its 200-day moving average. Against every other day in its history, that gap ranks at the 96th percentile — a wider gap than this stock usually carries. Over the past year MRVL closed higher on 53% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 14 years of records, MRVL finished the month higher 7 of 14 times, with a median return of +0.1% and an average of -0.3%. Its strongest month historically has been November at +9.8% on average, its weakest March at -2.2%. 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: MRVL has opened more than 2% away from the prior close in 256 of 3,270 sessions (7.8% of the time), with the largest gaps running +18.0% and -13.5%. 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, MRVL moved an average of 2.4% in the session after earnings, closing higher 2 of those 3 times, with a median move of +0.8% and a largest of +3.7%.

All figures computed from 3,271 daily closes between 2013-10-15 and 2026-10-14, split-adjusted, recomputed daily. Percentiles are against MRVL's own 13-year history, not a peer group or index.
