Does following Prelude Therapeutics Inc’s insiders pay?
From December 15, 2021 to April 23, 2026, 8 insiders reported 20 open-market purchases and 1 sale not made under a pre-set plan in Prelude Therapeutics Inc. Twelve months after each purchase was reported, the shares were −58.5% against the S&P 500 on average (median −59.1%), over 7 purchases with a full year of prices; 0% beat the index. After sales, the shares moved −56.5% 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 December 16, 2021 into $3,089 by November 2, 2026, −21.5% a year. It held shares 50% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $13,177 (+5.8% a year), and held throughout $17,340 (+12.0%).
