Edwards Lifesciences Corporation is currently running 24.7% annualised volatility over the last 21 sessions. Measured against EW's own 13 years of daily returns rather than a market-wide average, that is the 40th percentile — close to its own typical level, against a typical reading of 26.9%. 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.

EW is trading -34.7% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -18.4%, and the deepest was -46.3% in 2022. 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 +0.2% from its 200-day moving average. Against every other day in its history, that gap ranks at the 29th percentile — a narrower gap than it typically runs. Over the past year EW closed higher on 51% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, EW finished the month higher 6 of 13 times, with a median return of -6.4% and an average of -2.6%. Its strongest month historically has been November at +4.7% on average, its weakest October at -2.6%. 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: EW has opened more than 2% away from the prior close in 118 of 3,267 sessions (3.6% of the time), with the largest gaps running +11.0% and -13.1%. 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, EW moved an average of 2.1% in the session after earnings, closing higher 1 of those 3 times, with a median move of -0.3% and a largest of -5.5%.
