Joby Aviation Inc. is currently running 31.6% annualised volatility over the last 21 sessions. Measured against JOBY's own 6 years of daily returns rather than a market-wide average, that is the 7th percentile — unusually subdued by its own history, against a typical reading of 63.5%. 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.

JOBY is trading -73.5% below its running peak. Across 5 full years on file, its median worst-drawdown-in-a-year was -52.3%, and the deepest was -59.9% in 2021. 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 -42.3% from its 200-day moving average. Against every other day in its history, that gap ranks at the 2nd percentile — a narrower gap than it typically runs. Over the past year JOBY closed higher on 42% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 5 years of records, JOBY finished the month higher 2 of 5 times, with a median return of -0.4% and an average of -2.2%. Its strongest month historically has been May at +14.5% on average, its weakest January at -8.0%. 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: JOBY has opened more than 2% away from the prior close in 264 of 1,485 sessions (17.8% of the time), with the largest gaps running +9.1% and -7.3%. 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, JOBY moved an average of 9.2% in the session after earnings, closing higher 3 of those 3 times, with a median move of +5.2% and a largest of +19.4%.

All figures computed from 1,486 daily closes between 2020-11-09 and 2026-10-09, split-adjusted, recomputed daily. Percentiles are against JOBY's own 6-year history, not a peer group or index.
