Hedge fund Corvex Management has filed disclosures showing it sold more than $215M of ILMN stock across 42 transactions between May and early September. The activist firm, which holds a board seat at the gene-sequencing company, began offloading its position in the spring. The latest trades were filed on 4 September. Corvex's exit comes as Illumina's short interest sits at 5.7% of free float, a modest level that suggests the market is not heavily positioned against the stock.
On the buy side, UBER President and COO Andrew MacDonald picked up over $5.3M of Uber stock in early September, across two open-market purchases filed on 8 September. That is a discretionary buy from a senior operator, carrying more weight than a scheduled plan sale. Uber's short interest is just 2.4% of free float.
At PBF Energy, billionaire Carlos Slim has steadily reduced a major stake. Filings show he sold roughly $508M worth of shares from March through September 2026 alone, following $262M of selling earlier in the year. His buying in 2025 totalled only $42M. Short interest at PBF stands at 11.6% of free float. ORTEX's Index Rebalance Radar also notes PBF sits 0.7% below its Russell 2000 exit line, with potential forced selling of $452M if it falls out at the 30 October cut-off.
