Insiders Dump $870M in Dell

DELL tops this month's insider selling chart. Silver Lake Group — a 10% board-seat holder — offloaded over $869 million worth of shares across multiple filings in early June. Trades were priced between $420 and $435 per share.

The selling didn't stop there. General Counsel Richard Rothberg also filed a $8.2 million sale on June 17. That's five separate insiders filing sales at DELL within one month — a rare show of coordinated exits at the top.

SMMT stands out on the buy side. Summit Therapeutics Chairman and CEO Robert Duggan filed a $50 million purchase on June 12. He bought 3.8 million shares at $13.12. That's a strong vote of confidence from the top.

AMAT saw seven insiders sell a combined $114 million. CEO Gary Dickerson filed a $9.3 million sale on June 17, followed by division President Prabu Raja at $12.8 million. Applied Materials has rallied hard this year — executives are cashing in.

AAOI — Applied Optoelectronics — also saw its founder and CEO Thompson Lin file a $9.8 million sale. Four insiders sold a combined $25 million in the stock over the past month.

Ralph Lauren's founder RL Executive Chairman Ralph Lauren filed a $99.7 million sale in late May. That's the largest single C-suite trade in the period.
