Cadence Design Systems, Inc. is currently running 36.3% 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 77th 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 -20.3% 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 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 +0.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 18th percentile — a narrower gap than it typically runs. Over the past year CDNS closed higher on 49% of sessions, and it is currently 3 sessions into a falling streak.

On October specifically: over 14 years of records, CDNS finished the month higher 9 of 14 times, with a median return of +0.4% and an average of +0.9%. 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 146 of 3,268 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%.
