Rivian Automotive, Inc. is currently running 28.7% annualised volatility over the last 21 sessions. Measured against RIVN's own 5 years of daily returns rather than a market-wide average, that is the 1st percentile — unusually subdued by its own history, against a typical reading of 64.6%. 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.

RIVN is trading -92.5% below its running peak. Across 4 full years on file, its median worst-drawdown-in-a-year was -52.1%, and the deepest was -83.0% in 2022. 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 -18.8% from its 200-day moving average. Against every other day in its history, that gap ranks at the 28th percentile — a narrower gap than it typically runs. Over the past year RIVN closed higher on 46% of sessions, and it is currently 7 sessions into a falling streak.

On October specifically: over 5 years of records, RIVN finished the month higher 1 of 5 times, with a median return of -7.6% and an average of -10.3%. Its strongest month historically has been July at +15.3% on average, its weakest January at -16.3%. 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: RIVN has opened more than 2% away from the prior close in 87 of 1,235 sessions (7.0% of the time), with the largest gaps running +6.1% and -5.4%. 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, RIVN moved an average of 8.6% in the session after earnings, closing higher 1 of those 3 times, with a median move of -3.1% and a largest of -12.2%.
