Does following Sagimet Biosciences Inc.’s insiders pay?
From July 20, 2023 to July 22, 2026, 5 insiders reported 1 open-market purchase and 12 sales not made under a pre-set plan in Sagimet Biosciences Inc. Twelve months after each purchase was reported, the shares were −61.3% against the S&P 500 on average (median −61.3%), over 1 purchase with a full year of prices; 0% beat the index. After sales, the shares moved −59.5% 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 April 1, 2024 into $5,255 by November 2, 2026, −22.1% a year. It held shares 39% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $11,590 (+5.9% a year), and held throughout $14,915 (+16.8%).
