A story on the same day is not a cause, and a group move is not proof either. Group: the median of IDXX, LNTH, NEOG and NTLA that day, the largest companies in CLDX’s SEC industry; “moved with CLDX” means the same direction and at least half the size.

What’s next · results

Same industry

CLDX against four same-industry peers, a year at 100

CLDX is up 21.7% in a year. Neogen is up 2.2 times and Lantheus Holdings is up 87.1%. Of these four, Idexx Laboratories (−14.5%) and Intellia Therapeutics (−48.0%) did less. Weekly closes, Oct 10, 2025 = 100, on a log scale so a 2.2-fold rise and a 48.0% fall both read honestly.

End-of-day closes (Databento EOD), the last close of each week. The four peers are the largest US-listed companies by market value in CLDX’s SEC industry (In Vitro & In Vivo Diagnostic Substances) with a year of closes.
