Does following Standard Biotools Inc.’s insiders pay?
From May 24, 2011 to December 4, 2025, 36 insiders reported 107 open-market purchases and 22 sales not made under a pre-set plan in Standard Biotools Inc. Twelve months after each purchase was reported, the shares were +34.4% against the S&P 500 on average (median +36.1%), over 62 purchases with a full year of prices; 74% beat the index. After sales, the shares moved −41.0% against the index over 12 months (a negative figure means selling was the right call).
