Oscar Health, Inc. is currently running 42.4% annualised volatility over the last 21 sessions. Measured against OSCR's own 5 years of daily returns rather than a market-wide average, that is the 4th percentile — unusually subdued by its own history, against a typical reading of 69.4%. 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.

OSCR is trading -8.7% below its running peak. Across 5 full years on file, its median worst-drawdown-in-a-year was -49.3%, and the deepest was -79.4% in 2021. 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 +50.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 80th percentile — a wider gap than this stock usually carries. Over the past year OSCR closed higher on 47% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 5 years of records, OSCR finished the month higher 1 of 5 times, with a median return of -8.1% and an average of -11.3%. Its strongest month historically has been January at +18.7% on average, its weakest October at -11.3%. 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: OSCR has opened more than 2% away from the prior close in 285 of 1,392 sessions (20.5% of the time), with the largest gaps running +19.0% and -7.9%. 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, OSCR moved an average of 5.3% in the session after earnings, closing higher 3 of those 3 times, with a median move of +5.2% and a largest of +5.8%.

All figures computed from 1,394 daily closes between 2021-03-03 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against OSCR's own 6-year history, not a peer group or index.
