Bio-Techne Corporation is currently running 2.1% annualised volatility over the last 21 sessions. Measured against TECH's own 13 years of daily returns rather than a market-wide average, that is the 0th percentile — unusually subdued by its own history, against a typical reading of 26.5%. 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.

TECH is trading -46.2% below its running peak. Across 12 full years on file, its median worst-drawdown-in-a-year was -21.4%, and the deepest was -43.1% 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 +16.0% from its 200-day moving average. Against every other day in its history, that gap ranks at the 81st percentile — a wider gap than this stock usually carries. Over the past year TECH closed higher on 51% of sessions, and it is currently 1 session into a falling streak.

On October specifically: over 13 years of records, TECH finished the month higher 7 of 13 times, with a median return of +1.1% and an average of -1.1%. Its strongest month historically has been July at +4.7% on average, its weakest August at -3.0%. 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: TECH has opened more than 2% away from the prior close in 148 of 3,267 sessions (4.5% of the time), with the largest gaps running +9.7% and -16.4%. For anyone holding through an event, that rate is a better guide to overnight exposure than the intraday range.

All figures computed from 3,268 daily closes between 2013-10-15 and 2026-10-13, split-adjusted, recomputed daily. Percentiles are against TECH's own 13-year history, not a peer group or index.
