Does following Perrigo Co plc’s insiders pay?
From February 19, 2014 to November 14, 2025, 35 insiders reported 43 open-market purchases and 54 sales not made under a pre-set plan in Perrigo Co plc. Twelve months after each purchase was reported, the shares were −33.4% against the S&P 500 on average (median −38.4%), over 42 purchases with a full year of prices; 14% beat the index. After sales, the shares moved −21.4% against the index over 12 months (a negative figure means selling was the right call). 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 22, 2016 into $2,215 by November 2, 2026, −14.1% a year. It held shares 93% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $35,463 (+13.6% a year), and held throughout $40,159 (+15.1%).
