Insider buying on May 1, 2026

On May 1, 2026, 41 insiders at 28 companies filed 88 purchases reported on Form 4, worth $345.7M in all, with a median purchase of $5.2K. The largest was Ackman William A, Chief Executive Officer of Pershing Square USA, Ltd. (PSUS), who reported buying 3,500,000 shares worth $175.0M. Officers accounted for 59 purchases, directors who are not officers for 22, and 10% owners with no board or officer role for 7. Chief executives and chief financial officers filed 50 purchases: Ackman William A, Chief Executive Officer of Pershing Square USA, Ltd. (PSUS); Cheung Martina, CEO & President, Director of S&P Global Inc. (SPGI); Maskin Scott, Chief Executive Officer, Director, 10% owner of SUNation Energy, Inc. (SUNE) among others. 10 companies showed cluster buying, two or more insiders buying within 7 days, among them PSUS (8 insiders), PCSA (6 insiders), NWFL (4 insiders), AVLN (3 insiders). For 17 insiders of 41, this was the first purchase of that company's stock on our record. That is more than the 41 purchases filed on Apr 30, 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.
