Caseys General Stores, Inc. is currently running 52.7% annualised volatility over the last 21 sessions. Measured against CASY's own 13 years of daily returns rather than a market-wide average, that is the 97th percentile — an extreme by its own standards, against a typical reading of 21.5%. 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.

CASY is trading -32.9% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -14.8%, and the deepest was -33.4% in 2020. 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 -15.7% from its 200-day moving average. Against every other day in its history, that gap ranks at the 1st percentile — a narrower gap than it typically runs. Over the past year CASY closed higher on 47% of sessions, and it is currently 2 sessions into a falling streak.

On October specifically: over 13 years of records, CASY finished the month higher 9 of 13 times, with a median return of +2.2% and an average of +2.3%. Its strongest month historically has been November at +4.8% on average, its weakest December at -2.1%. 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: CASY has opened more than 2% away from the prior close in 63 of 3,267 sessions (1.9% of the time), with the largest gaps running +5.0% and -12.2%. 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, CASY moved an average of 8.8% in the session after earnings, closing higher 1 of those 3 times, with a median move of -3.6% and a largest of +16.6%.

All figures computed from 3,268 daily closes between 2013-10-07 and 2026-10-05, split-adjusted, recomputed daily. Percentiles are against CASY's own 13-year history, not a peer group or index.
