Insider buying on Feb 4, 2026

On Feb 4, 2026, 35 insiders at 31 companies filed 55 purchases reported on Form 4, worth $45.6M in all, with a median purchase of $27.4K. The largest was Mitsui Sumitomo Insurance Co Ltd, 10% owner of Berkley W R Corp (WRB), who reported buying 237,062 shares worth $16.1M. Officers accounted for 19 purchases, directors who are not officers for 21, and 10% owners with no board or officer role for 15. Chief executives and chief financial officers filed 6 purchases: Altman Peter, President and CEO, Director of BioCardia, Inc. (BCDA); Boreta Ronald S, President, CEO, and Treasurer, Director, 10% owner of Agassi Sports Entertainment Corp. (AASP); Quinn William P., President, CEO and CFO, Director of Bolt Biotherapeutics, Inc. (BOLT) among others. 11 companies showed cluster buying, two or more insiders buying within 7 days, among them FEAM (3 insiders), EMPD (3 insiders), PFBX (3 insiders), CVCO (3 insiders). For 4 insiders of 35, this was the first purchase of that company's stock on our record. That is fewer than the 71 purchases filed on Feb 3, 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.
