CVS Health Corporation is currently running 27.9% annualised volatility over the last 21 sessions. Measured against CVS's own 13 years of daily returns rather than a market-wide average, that is the 73rd percentile — a little above its own norm, against a typical reading of 22.8%. 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.

CVS is trading -22.8% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -23.8%, and the deepest was -46.7% in 2024. 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 -0.4% from its 200-day moving average. Against every other day in its history, that gap ranks at the 49th percentile — close to the gap it normally carries. Over the past year CVS closed higher on 49% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, CVS finished the month higher 6 of 13 times, with a median return of -0.7% and an average of -0.9%. Its strongest month historically has been November at +4.6% on average, its weakest March at -1.3%. 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: CVS has opened more than 2% away from the prior close in 41 of 3,265 sessions (1.3% of the time), with the largest gaps running +5.1% and -7.4%. 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, CVS moved an average of 1.6% in the session after earnings, closing higher 2 of those 3 times, with a median move of +0.3% and a largest of -3.0%.

All figures computed from 3,266 daily closes between 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against CVS's own 13-year history, not a peer group or index.
