Does following Twist Bioscience Corp’s insiders pay?
From August 20, 2019 to October 27, 2026, 17 insiders reported 2 open-market purchases and 258 sales not made under a pre-set plan in Twist Bioscience Corp. Twelve months after each purchase was reported, the shares were +81.6% against the S&P 500 on average (median +81.6%), over 2 purchases with a full year of prices; 50% beat the index. After sales, the shares moved +46.8% 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 16, 2022 into $12,804 by November 2, 2026, +5.7% a year. It held shares 41% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $14,746 (+9.1% a year), and held throughout $20,083 (+17.0%).
