NVIDIA director Mark Stevens filed to sell over $410M worth of shares in early September — the largest single-insider disclosure period in the data. Stevens offloaded 1.85 million shares across seven transactions between August 31 and September 2, at prices ranging from $220 to $226. The sales were filed with regulators on September 2.
Meanwhile, the most striking buy came from an unlikely corner. Bill Gates filed to purchase $241M in Republic Services — a waste management company — across 15 separate transactions filed between September 1 and September 3. Gates bought over 1 million shares at roughly $221–$224 each. The sustained, multi-day buying is a strong signal of conviction, not a one-off move.
Over at Illumina, activist fund Corvex Management LP — which holds a board seat — filed $57M in sales across 12 transactions. Corvex trimmed its position between September 2 and 4. The fund's board representation makes this more than a routine portfolio adjustment.
Post Holdings Chairman Emeritus William Stiritz disclosed $32M in sales filed September 3. saw its 10% board-represented owner Ian Snow sell $19M, also filed September 3.
The Gates RSG buying cluster stands out most. It is fresh, large, and discretionary — a sharp contrast to the director-level selling seen elsewhere this week.
