Insiders Buy Big, Sell Bigger

Insider filings this week paint a split picture. Executives and major shareholders are pulling cash out of tech giants. But at one biotech, the CEO just made a massive bet on his own company.

Summit Therapeutics CEO doubles down. SMMT Chairman and CEO Robert Duggan filed on June 12, showing he bought $50M worth of shares on that same day — nearly 3.8 million shares. President and CEO Maky Zanganeh also filed a $1.5M purchase. The CFO added another $722K. Three C-suite insiders buying in the same week signals real conviction from the top.

NVIDIA director cashes out $221M. Director Mark Stevens filed four separate sales at NVDA, totalling over $221M in just three days (June 2–4). The stock recently hit record highs. Stevens sold 1 million shares across multiple tranches.

Dell insiders dump $919M. DELL saw five insiders file sales in the past two weeks. Silver Lake Group, a 10% owner and board member, led the selling. Total disclosed sales topped $919M across 927 transactions. That is a significant exit by the company's largest outside backer.

Applied Materials sees six sellers. Six insiders at AMAT filed sales totalling $107M over the same period. No purchases were reported.

This is not financial advice.
