Insider filings this week reveal a striking split in confidence across sectors.
SMMT Chairman and CEO Robert Duggan filed on June 12 disclosing a $50M personal purchase of 3.81 million shares at $13.12. That is the single largest US C-level buy filed in the past two weeks. He was not alone. President Maky Zanganeh and CFO Manmeet Soni both bought shares on June 4, adding $1.46M and $0.72M respectively. Three executives buying in the same week signals strong internal confidence at the clinical-stage biotech.
The picture looks very different at NVDA. Independent Director Mark Stevens filed sales of $221M across June 2–4, unloading 1 million shares near the $220 mark. Chairman Emeritus Stephen Neal added another $3.3M sale on June 3. Combined, NVIDIA insiders sold over $224M in a single week.
Meanwhile, ACS CEO Florentino Perez filed disclosures this week covering three separate purchases made in late December 2025. The total came to over $18M. The delayed filing bundles trades from December 23, 29, and 30. That is a notable late disclosure of persistent buying by the construction giant's chief executive.
The Walton Family Holdings Trust also filed a $184M WMT sale on June 4, continuing the family's pattern of routine stake reductions in Walmart.
