Does following Crispr Therapeutics AG’s insiders pay?
From December 7, 2017 to October 20, 2026, 16 insiders reported 8 open-market purchases and 48 sales not made under a pre-set plan in Crispr Therapeutics AG. Twelve months after each purchase was reported, the shares were +23.2% against the S&P 500 on average (median +23.1%), over 7 purchases with a full year of prices; 57% beat the index. After sales, the shares moved −16.5% 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 January 12, 2018 into $31,577 by November 2, 2026, +14.0% a year. It held shares 39% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $18,671 (+7.4% a year), and held throughout $31,082 (+13.8%).
