Insider buying on Jan 16, 2026

On Jan 16, 2026, 29 insiders at 17 companies filed 92 purchases reported on Form 4, worth $37.8M in all, with a median purchase of $2.3K. The largest was MS&AD Insurance Group Holdings, Inc., 10% owner of Berkley W R Corp (WRB), who reported buying 241,309 shares worth $16.4M. Officers accounted for 25 purchases, directors who are not officers for 7, and 10% owners with no board or officer role for 58. Chief executives and chief financial officers filed 9 purchases: Sloane Barry, President, Chairman & CEO, Director of NewtekOne, Inc. (NEWT); Hand Joseph Thomas, President & CEO, Director of York Water Co (YORW); Nassif Mikheal, CEO, Director of Neogen Corp (NEOG) among others. 8 companies showed cluster buying, two or more insiders buying within 7 days, among them YORW (7 insiders), IMRX (5 insiders), NEWT (4 insiders), GLQ (4 insiders). For 6 insiders of 29, this was the first purchase of that company's stock on our record. That is more than the 47 purchases filed on Jan 15, 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.
