Nvidia Director Dumps $411M; Gates Quietly Buys Trash

An NVDA board member filed a major sell. Mark A. Stevens, an independent director at Nvidia, disclosed sales totaling $411 million between August 31 and September 2. Filings were submitted September 2. The trades spanned 1.85 million shares across multiple transactions. No 10b5-1 plan was disclosed in the data, making this a more notable signal. Nvidia carries a $5.3 trillion market cap, and its short interest sits at just 1.3% of free float.

The contrast comes from RSG. Bill Gates — through his investment vehicle — filed $234 million in purchases of Republic Services stock between August 28 and September 2. Filings landed September 3. Gates bought over 1 million shares in the waste management giant. The discretionary buy is a strong signal; insiders rarely put this kind of money to work by accident.

Elsewhere, ILMN saw activist fund Corvex Management sell $34 million in shares. POST Chairman Emeritus William Stiritz filed $32 million in sales. NMIH CEO Adam Pollitzer sold $7.7 million in shares on September 4, filed the same day.

On the healthcare side, THC COO Lisa Foo sold $6.4 million in Tenet Healthcare stock at end of August. And a director at WBD filed a $5.7 million sale in early September.

The Gates buy at RSG stands out as the clearest bullish signal this week.
