Three standout insider trades filed recently show executives and major shareholders putting real money to work — and one high-profile biotech CEO cashing out at the top.
Bill Gates keeps buying Republic Services. The Microsoft co-founder filed 65 separate purchases in Republic Services, totalling over $926 million between August 10 and September 2. Gates holds the stock as a main shareholder and has been buying steadily across a wide price range (~$219–$223 per share). That kind of persistent accumulation is hard to dismiss as a passive rebalancing.
Uber's COO puts skin in the game. Andrew MacDonald, President and COO of Uber Technologies, filed on September 8 showing he bought $5.3 million worth of shares on September 4 at an average of around $75.65. These were open-market discretionary purchases — no 10b5-1 plan declared — making the signal stronger. It marks a notable vote of confidence from within the C-suite.
Evolution AB's mystery buyer goes big. Kenneth Bryan Dart, listed as the main shareholder of Swedish gaming giant Evolution AB, filed in late August disclosing purchases totalling roughly — made in July at prices around SEK 690–695 per share. The sheer size of Dart's stake-building stands out. Meanwhile, an associate at the firm was selling small clips in the same period, creating a split signal.
argenx CEO sells $21M. Tim Van Hauwermeiren, founder and CEO of argenx, filed on September 5 showing he sold $21 million in shares on September 3 at ~$908 each. The CMO and General Counsel also sold in the same window — a cluster of executive selling worth watching.
