Insider buying on May 20, 2026

On May 20, 2026, 80 insiders at 69 companies filed 126 purchases reported on Form 4, worth $83.3M in all, with a median purchase of $33.7K. The largest was Abu Dhabi Investment Authority, 10% owner of CIK 1959568, who reported buying 16,877 shares worth $30.0M. Officers accounted for 60 purchases, directors who are not officers for 49, and 10% owners with no board or officer role for 14. Chief executives and chief financial officers filed 40 purchases: Jia Li, Chief Executive Officer, Director of U Power Ltd (UCAR); Tharby Linda M, Chief Executive Officer, Director of KORU Medical Systems, Inc. (KRMD); Fan Zhen, CEO & Chairman, Director, 10% owner of Haoxi Health Technology Ltd (HAO) among others. 24 companies showed cluster buying, two or more insiders buying within 7 days, among them FRPT (5 insiders), GRNT (5 insiders), KRMD (4 insiders), CCAP (3 insiders). For 20 insiders of 80, this was the first purchase of that company's stock on our record. That is fewer than the 127 purchases filed on May 19, 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.
