On Jan 14, 2026, 23 insiders at 20 companies filed 35 purchases reported on Form 4, worth $100.9M in all, with a median purchase of $17.5K. The largest was Mpm Oncology Innovations Fund Lp, 10% owner of Aktis Oncology, Inc. (AKTS), who reported buying 1,112,777 shares worth $20.0M. Officers accounted for 11 purchases, directors who are not officers for 9, and 10% owners with no board or officer role for 12. Chief executives and chief financial officers filed 4 purchases: Cole Matthew Ryan, Chief Executive Officer, Director of Strive, Inc. (ASST); Patel Snehal, CEO and CFO, Director, 10% owner of Greenwich LifeSciences, Inc. (GLSI); Schubert Gary, Chief Executive Officer of Innovative Food Holdings Inc (IVFH) among others. 7 companies showed cluster buying, two or more insiders buying within 7 days, among them AKTS (6 insiders), GLQ (3 insiders), GAM (2 insiders), IMRX (2 insiders). For 8 insiders of 23, this was the first purchase of that company's stock on our record. That is more than the 30 purchases filed on Jan 13, 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.
