On Aug 10, 2026, 103 insiders at 61 companies filed 142 purchases reported on Form 4, worth $34.3M in all, with a median purchase of $29.7K. The largest was venBio Global Strategic Fund IV, L.P., 10% owner of Attovia Therapeutics, Inc. (ATTO), who reported buying 382,352 shares worth $6.5M. Officers accounted for 62 purchases, directors who are not officers for 51, and 10% owners with no board or officer role for 25. Chief executives and chief financial officers filed 23 purchases: Huang Jack Jiajia, Chief Executive Officer, Director, 10% owner of 51Talk Online Education Group (COE); Singh Jesse G, Chief Executive Officer, Director of Fortune Brands Innovations, Inc. (FBIN); Wood Larry L, President, CEO, Director of PROCEPT BioRobotics Corp (PRCT) among others. 16 companies showed cluster buying, two or more insiders buying within 7 days, among them TSM (30 insiders), ATTO (6 insiders), BLSM (6 insiders), CC (5 insiders). For 20 insiders of 103, this was the first purchase of that company's stock on our record. That is more than the 58 purchases filed on Aug 7, 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.
