Insider buying on Aug 18, 2026

On Aug 18, 2026, 65 insiders at 55 companies filed 87 purchases reported on Form 4, worth $68.9M in all, with a median purchase of $37.9K. The largest was Catalyst4, Inc., 10% owner of MapLight Therapeutics, Inc. (MLPT), who reported buying 4,400,000 shares worth $50.1M. Officers accounted for 32 purchases, directors who are not officers for 32, and 10% owners with no board or officer role for 17. Chief executives and chief financial officers filed 15 purchases: Rieger Jayson, CEO and President, Director of Verrica Pharmaceuticals Inc. (VRCA); Heshmatpour Amir F, CEO, President, Director, 10% owner of Neonc Technologies Holdings, Inc. (NTHI); Schwartz Todd G., Chief Executive Officer, Director, 10% owner of OppFi Inc. (OPFI) among others. 22 companies showed cluster buying, two or more insiders buying within 7 days, among them CDNL (7 insiders), AMRZ (6 insiders), ACON (6 insiders), CODI (5 insiders). For 16 insiders of 65, this was the first purchase of that company's stock on our record. That is fewer than the 123 purchases filed on Aug 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.
