Week of Jul 13 – Jul 17, 2026
By Trabud Research Team · SEC Form 4 & insider trading data analysts
Last updated:
Insider buying was dominated by Sumitomo Mitsui Financial Group’s $318.7 million purchase of 5.9 million JEF shares, with Prudential entities adding $60 million in TYG and smaller buys in STDN and COE. Selling activity was far larger in dollar terms, led by Niccolo Camerana’s $478 million sale of 2,500 STNG shares, followed by a $401 million disposal in SN, Baker Bros.’ $318 million exit from CELC, and a $294 million sale by UMC’s CFO. The contrast between a single outsized financial-sector purchase and multiple nine-figure sales across energy, consumer, biotech, and semiconductors points to selective accumulation amid broad profit-taking.
