UBER President and COO Andrew Gordon MacDonald spent $5.3 million buying his own company's stock on September 4. The filing landed on September 8. MacDonald picked up around 70,000 shares in two tranches, lifting his total holding above 426,000 shares. Open-market purchases by a sitting COO carry real weight as a signal of confidence.
The contrast with ILMN is sharp. Activist fund Corvex Management, which holds a board seat at Illumina, filed a string of sales over September 2 to 4, offloading more than $45 million worth of stock across roughly a dozen transactions. The pace was steady rather than a single block sale, suggesting an orderly exit rather than a distressed dump. Corvex's position fell to around 770,000 shares after the selling. Activists rarely sell this aggressively while retaining board representation, making the move worth watching.
At the smaller end, two directors at HELP Helus Pharma each bought $1.2 million of stock on September 3 and 4. Director Eric So and Director Paul Glavine each acquired 100,000 shares. Cluster buying by multiple directors on the same days is often the clearest insider signal of all.
Separately, Japan Post Holdings filed a $2.4 million sale in AFL Aflac on September 3, a routine reduction by a long-term institutional holder rather than a conviction move.
