Insider buying on Mar 31, 2026

On Mar 31, 2026, 39 insiders at 34 companies filed 61 purchases reported on Form 4, worth $28.7M in all, with a median purchase of $45.4K. The largest was Shah Rajeev M., Director of Mineralys Therapeutics, Inc. (MLYS), who reported buying 310,700 shares worth $7.4M. Officers accounted for 30 purchases, directors who are not officers for 25, and 10% owners with no board or officer role for 5. Chief executives and chief financial officers filed 18 purchases: Moulder Leon O Jr, Chief Executive Officer, Director of Zenas BioPharma, Inc. (ZBIO); Siegall Clay B, President and CEO, Director of Immunome Inc. (IMNM); Stenberg Jon, President & CEO, Director of Citizens, Inc. (CIA) among others. 12 companies showed cluster buying, two or more insiders buying within 7 days, among them CIK 1849089 (4 insiders), IAUX (4 insiders), ZBIO (3 insiders), CRT (3 insiders). For 12 insiders of 39, this was the first purchase of that company's stock on our record. That is fewer than the 74 purchases filed on Mar 30, 2026. A Form 4 is due within two business days of the trade, so most of these purchases were made earlier in the week. Code P also covers shares bought privately from the company, so one large figure can be a negotiated placement rather than buying on the exchange.
