Insider buying on Jan 21, 2026

On Jan 21, 2026, 27 insiders at 20 companies filed 40 purchases reported on Form 4, worth $102.4M in all, with a median purchase of $24.9K. The largest was Watsa V Prem Et Al, 10% owner of Under Armour, Inc. (UA), who reported buying 5,000,000 shares worth $29.4M. Officers accounted for 18 purchases, directors who are not officers for 11, and 10% owners with no board or officer role for 11. Chief executives and chief financial officers filed 8 purchases: Siokas Grigorios, Chief Executive Officer, Director, 10% owner of Cosmos Health Inc. (COSM); Nichtberger Steven, President & CEO, Director of Cabaletta Bio, Inc. (CABA); Mafrice Daniel, Chairman, President and CEO, Director of CIK 2045370 among others. 5 companies showed cluster buying, two or more insiders buying within 7 days, among them CABA (8 insiders), ISBA (7 insiders), IMRX (3 insiders), WRB (2 insiders). For 6 insiders of 27, this was the first purchase of that company's stock on our record. That is fewer than the 66 purchases filed on Jan 20, 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.
