Week of Aug 10 – Aug 14, 2026
By Trabud Research Team · SEC Form 4 & insider trading data analysts
Last updated:
Insider buying was led by William H. Gates III, who added roughly $186.5 million in Republic Services (RSG) stock, while Braveheart Bio (BRVE) saw a coordinated $89.6 million purchase from OrbiMed and its directors, signaling strong conviction in the waste management and biotech sectors. On the selling side, Primo Brands (PRMB) saw a massive $994.8 million exit from its directors and private equity backers, with Corebridge Financial (CRBD), First Advantage (FA), and OPENLANE (OPLN) also experiencing significant multimillion-dollar sell-offs by major institutional holders. The heavy distribution in PRMB, CRBD, FA, and OPLN suggests continued profit-taking and potential exits by private equity sponsors, contrasting sharply with the concentrated accumulation in RSG and BRVE.
