Does following Silgan Holdings Inc’s insiders pay?
From February 18, 2010 to November 10, 2025, 21 insiders reported 5 open-market purchases and 137 sales not made under a pre-set plan in Silgan Holdings Inc. Twelve months after each purchase was reported, the shares were +7.1% against the S&P 500 on average (median +6.5%), over 3 purchases with a full year of prices; 100% beat the index. After sales, the shares moved −6.0% against the index over 12 months (a negative figure means selling was the right call). 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 May 23, 2014 into $17,444 by November 2, 2026, +4.6% a year. It held shares 26% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $16,807 (+4.3% a year), and held throughout $48,959 (+13.7%).
