Cytokinetics Incorporated is currently running 32.8% annualised volatility over the last 21 sessions. Measured against CYTK's own 13 years of daily returns rather than a market-wide average, that is the 6th percentile — unusually subdued by its own history, against a typical reading of 53.0%. 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.

CYTK is trading -28.1% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -41.6%, and the deepest was -76.8% in 2014. 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 -10.5% from its 200-day moving average. Against every other day in its history, that gap ranks at the 24th percentile — a narrower gap than it typically runs. Over the past year CYTK closed higher on 47% of sessions, and it is currently 2 sessions into a falling streak.

On October specifically: over 13 years of records, CYTK finished the month higher 6 of 13 times, with a median return of -3.1% and an average of -1.8%. Its strongest month historically has been December at +9.9% on average, its weakest September at -4.1%. 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: CYTK has opened more than 2% away from the prior close in 413 of 3,224 sessions (12.8% of the time), with the largest gaps running +21.6% and -32.4%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,226 daily closes between 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against CYTK's own 13-year history, not a peer group or index.
