Does following Atmus Filtration Technologies Inc.’s insiders pay?
From November 9, 2023 to August 18, 2026, 6 insiders reported 5 open-market purchases and 5 sales not made under a pre-set plan in Atmus Filtration Technologies Inc. Twelve months after each purchase was reported, the shares were +38.6% against the S&P 500 on average (median +17.5%), over 3 purchases with a full year of prices; 100% beat the index. That rests on fewer than 20 purchases, too few to read much into. Buying each purchase the day after it was reported, an equal amount each, held 12 months or until that insider reported a sale, would have turned $10,000 on November 10, 2023 into $20,898 by November 2, 2026, +28.3% a year. It held shares 76% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $15,728 (+16.6% a year), and held throughout $17,803 (+21.5%).
