Cadence Design Systems, Inc. is currently running 37.9% annualised volatility over the last 21 sessions. Measured against CDNS's own 13 years of daily returns rather than a market-wide average, that is the 80th percentile — elevated for this stock, against a typical reading of 27.0%. 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.

CDNS is trading -14.5% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -18.6%, and the deepest was -31.3% 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 +8.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 46th percentile — close to the gap it normally carries. Over the past year CDNS closed higher on 50% of sessions, and it is currently 4 sessions into a rising streak.

On October specifically: over 13 years of records, CDNS finished the month higher 9 of 13 times, with a median return of +0.5% and an average of +2.0%. Its strongest month historically has been May at +4.7% on average, its weakest September at -0.7%. 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: CDNS has opened more than 2% away from the prior close in 147 of 3,267 sessions (4.5% of the time), with the largest gaps running +6.1% and -11.8%. 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, CDNS moved an average of 2.7% in the session after earnings, closing higher 1 of those 3 times, with a median move of -0.8% and a largest of -4.7%.

All figures computed from 3,268 daily closes between 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against CDNS's own 13-year history, not a peer group or index.
