Oklo Inc. is currently running 89.0% annualised volatility over the last 21 sessions. Measured against OKLO's own 5 years of daily returns rather than a market-wide average, that is the 65th percentile — a little above its own norm, against a typical reading of 27.8%. 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.

OKLO is trading -78.7% below its running peak. Across 4 full years on file, its median worst-drawdown-in-a-year was -34.9%, and the deepest was -68.7% in 2024. 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 -39.3% from its 200-day moving average. Against every other day in its history, that gap ranks at the 5th percentile — a narrower gap than it typically runs. Over the past year OKLO closed higher on 45% of sessions, and it is currently 1 session into a falling streak.

On September specifically: over 6 years of records, OKLO finished the month higher 4 of 6 times, with a median return of +0.2% and an average of +15.6%. Its strongest month historically has been October at +36.4% on average, its weakest February at -9.9%. 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: OKLO has opened more than 2% away from the prior close in 124 of 1,277 sessions (9.7% of the time), with the largest gaps running +7.4% and -10.2%. 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, OKLO moved an average of 4.9% in the session after earnings, closing higher 0 of those 3 times, with a median move of -3.1% and a largest of -8.9%.

All figures computed from 1,278 daily closes between 2021-07-08 and 2026-09-18, split-adjusted, recomputed daily. Percentiles are against OKLO's own 5-year history, not a peer group or index.
