Does following Ategrity Specialty Insurance Co Holdings’s insiders pay?
From August 15, 2025 to May 5, 2026, 4 insiders reported 5 open-market purchases and 0 sales not made under a pre-set plan in Ategrity Specialty Insurance Co Holdings. Twelve months after each purchase was reported, the shares were +13.5% against the S&P 500 on average (median +16.0%), over 4 purchases with a full year of prices; 75% 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 August 18, 2025 into $10,991 by November 2, 2026, +8.1% a year. It held shares 100% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $11,919 (+15.7% a year), and held throughout $11,919 (+15.7%).
