Insider buying on Jul 30, 2026

On Jul 30, 2026, 35 insiders at 21 companies filed 50 purchases reported on Form 4, worth $56.8M in all, with a median purchase of $15.4K. The largest was Abu Dhabi Investment Authority, 10% owner of CIK 1965934, who reported buying 932,917 shares worth $22.9M. Officers accounted for 33 purchases, directors who are not officers for 8, and 10% owners with no board or officer role for 9. Chief executives and chief financial officers filed 13 purchases: Huang Jack Jiajia, Chief Executive Officer, Director, 10% owner of 51Talk Online Education Group (COE); Morris Susan, Chief Executive Officer, Director of Albertsons Companies, Inc. (ACI); Siokas Grigorios, Chief Executive Officer, Director, 10% owner of Cosmos Health Inc. (COSM) among others. 5 companies showed cluster buying, two or more insiders buying within 7 days, among them CIK 277638 (13 insiders), MLPT (2 insiders), [NONE] (2 insiders), ACI (2 insiders). For 6 insiders of 35, this was the first purchase of that company's stock on our record. That is more than the 26 purchases filed on Jul 29, 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.
