Insiders Dump Big, One Founder Buys

The biggest insider story of the past two weeks comes from ASTS. Founder and CEO Abel Avellan filed on June 23 that he sold $146.7 million worth of shares — 2.5 million shares at $58.68 each — just days after the trade. AST SpaceMobile stock has climbed sharply in 2026, making this one of the largest C-suite exits recently filed.

At AGX, Chairman William Griffin filed multiple large sales totalling over $69 million. Trades occurred between June 12 and June 22. Four insiders in total have filed sales at Argan in the past fortnight, with zero buying recorded.

BBY founder and Chairman Emeritus Richard Schulze filed $32.7 million in sales on June 26. He sold nearly 419,000 shares across two days at around $78 each. Best Buy's founder exiting at this scale is worth watching.

Applied Materials AMAT saw five insiders file sales totalling $87 million in the past two weeks. No purchases were recorded alongside the sales.

The lone contrarian signal: ENN Energy Holdings founder Wang Yusuo filed a $13.2 million purchase, buying 2.25 million shares at HK$46.02. A founder buying at scale stands out in a week dominated by selling.
