Insider buying on Apr 28, 2026

On Apr 28, 2026, 23 insiders at 20 companies filed 27 purchases reported on Form 4, worth $24.6M in all, with a median purchase of $45.2K. The largest was GoldenTree Asset Management LLC, 10% owner of CIK 2052250, who reported buying 1,956,947 shares worth $20.0M. Officers accounted for 13 purchases, directors who are not officers for 9, and 10% owners with no board or officer role for 5. Chief executives and chief financial officers filed 8 purchases: Winfrey Christopher L, President and CEO, Director of Charter Communications, Inc. /mo/ (CHTR); Hong Zhifang, CEO, Director, 10% owner of DarkIris Inc. (DKI); Handy Edward O. III, Chairman and CEO, Director of Washington Trust Bancorp Inc (WASH) among others. 6 companies showed cluster buying, two or more insiders buying within 7 days, among them EFOR (13 insiders), CHTR (3 insiders), WASH (3 insiders), NTHI (3 insiders). For 7 insiders of 23, this was the first purchase of that company's stock on our record. That is fewer than the 175 purchases filed on Apr 27, 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.
