Insider buying on Sep 21, 2026

On Sep 21, 2026, 45 insiders at 37 companies filed 86 purchases reported on Form 4, worth $369.0M in all, with a median purchase of $232.8K. The largest was Berkshire Hathaway Inc, 10% owner of Lennar Corp /new/ (LEN, LEN.B), who reported buying 1,218,429 shares worth $93.1M. Officers accounted for 32 purchases, directors who are not officers for 11, and 10% owners with no board or officer role for 41. Chief executives and chief financial officers filed 19 purchases: Tan Anthony Ping Yeow, Chief Executive Officer, Director of Grab Holdings Ltd (GRAB); Cohen Ryan, President, CEO and Chairman, Director of GameStop Corp. (GME); Halstead Michael, Chief Executive Officer of Helus Pharma Inc. (CYBN) among others. 12 companies showed cluster buying, two or more insiders buying within 7 days, among them BBD (21 insiders), RWT (6 insiders), CBKM (4 insiders), BUKS (3 insiders). For 14 insiders of 45, this was the first purchase of that company's stock on our record. That is more than the 65 purchases filed on Sep 18, 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.
