On Jun 30, 2026, 23 insiders at 22 companies filed 58 purchases reported on Form 4, worth $19.1M in all, with a median purchase of $76.2K. The largest was Huang Jack Jiajia, Chief Executive Officer, Director, 10% owner of 51Talk Online Education Group (COE), who reported buying 210,000 shares worth $3.2M. Officers accounted for 27 purchases, directors who are not officers for 19, and 10% owners with no board or officer role for 7. Chief executives and chief financial officers filed 19 purchases: Huang Jack Jiajia, Chief Executive Officer, Director, 10% owner of 51Talk Online Education Group (COE); Hyzak Dwayne L., CEO, SMD, Director of Msc Income Fund, Inc. (MSIF); Hill John C, CEO & President, Director of Central Securities Corp (CET) among others. 6 companies showed cluster buying, two or more insiders buying within 7 days, among them LILA (4 insiders), AVO (2 insiders), SBSW (2 insiders), MSIF (2 insiders). For 2 insiders of 23, this was the first purchase of that company's stock on our record. That is fewer than the 64 purchases filed on Jun 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.
