Disc Medicine, Inc. insider trading
Every open-market purchase and sale by Disc Medicine, Inc.'s officers, directors and largest shareholders since November 4, 2021, and what the share price did next.
Does following Disc Medicine, Inc.’s insiders pay?
From May 18, 2021 to September 15, 2026, 22 insiders reported 9 open-market purchases and 44 sales not made under a pre-set plan in Disc Medicine, Inc. Twelve months after each purchase was reported, the shares were +31.5% against the S&P 500 on average (median +9.2%), over 8 purchases with a full year of prices; 75% beat the index. After sales, the shares moved −14.6% 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 19, 2021 into $4,509 by November 2, 2026, −13.6% a year. It held shares 55% of the time; the S&P 500 on those same days, with Treasury bills otherwise, made $14,937 (+7.7% a year), and held throughout $19,814 (+13.4%).
