Insider buying on Aug 21, 2026

On Aug 21, 2026, 66 insiders at 57 companies filed 88 purchases reported on Form 4, worth $349.4M in all, with a median purchase of $29.3K. The largest was Sumitomo Mitsui Financial Group, Inc., Director of Jefferies Financial Group Inc. (JEF), who reported buying 5,906,542 shares worth $324.0M. Officers accounted for 33 purchases, directors who are not officers for 37, and 10% owners with no board or officer role for 17. Chief executives and chief financial officers filed 22 purchases: Huang Jack Jiajia, Chief Executive Officer, Director, 10% owner of 51Talk Online Education Group (COE); Minicucci Benito, CEO AND PRESIDENT, Director of Alaska Air Group, Inc. (ALK); Bailey David F, Chief Executive Officer, Director, 10% owner of Nakamoto Inc. (NAKA) among others. 19 companies showed cluster buying, two or more insiders buying within 7 days, among them INV (4 insiders), AIAI (4 insiders), AFCG (3 insiders), REFI (3 insiders). For 15 insiders of 66, this was the first purchase of that company's stock on our record. That is fewer than the 125 purchases filed on Aug 20, 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.
