Insider buying on Jul 20, 2026

On Jul 20, 2026, 26 insiders at 26 companies filed 32 purchases reported on Form 4, worth $52.4M in all, with a median purchase of $30.6K. The largest was Lincoln Financial Investments Corp, 10% owner of LNBIX, who reported buying 2,460,630 shares worth $25.0M. Officers accounted for 9 purchases, directors who are not officers for 12, and 10% owners with no board or officer role for 9. Chief executives and chief financial officers filed 7 purchases: Huang Jack Jiajia, Chief Executive Officer, Director, 10% owner of 51Talk Online Education Group (COE); Liu Chang, Chief Executive Officer, Director, 10% owner of 17 Education & Technology Group Inc. (YQ); Wang Chun Kai, Chief Executive Officer, Director of Obook Holdings Inc. (OWLS) among others. 3 companies showed cluster buying, two or more insiders buying within 7 days: YORW (7 insiders), ANIX (2 insiders), GRML (2 insiders). For 10 insiders of 26, this was the first purchase of that company's stock on our record. That is fewer than the 47 purchases filed on Jul 17, 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.
