Insiders Signal Confidence Amid Big Exit Plays

The standout buy filed in early September came from UBER. President and COO Andrew Gordon MacDonald picked up 70,000 shares worth $5.3 million on September 4, with the trade disclosed on September 8. That is a rare open-market purchase from a C-level executive. It carries more weight than a routine grant or option exercise.

On the sell side, activist fund Corvex Management dumped $57.2 million of ILMN stock across 12 transactions between September 2 and 4. Corvex held a board seat at Illumina. The concentrated selling over just three days, all filed on September 4, suggests a clean exit rather than routine portfolio trimming.

Also filing sales in early September was Carlos Slim Helu, the 10% shareholder of refiner PBF. He sold roughly $92.9 million worth of PBF shares across 16 trades between late July and September 2, with the bundle filed on September 4. PBF operates in a sector facing pressure from California's ZEV data, which showed new electric vehicle registrations falling 37% year-on-year in July 2026 to 80,392 units, the weakest Q3 reading in three years, according to ORTEX alt data. That trend does not help fuel demand narratives for refiners.

The NMI Holdings CEO also filed a $7.7 million sale on September 4. Three separate names filing sizeable sells on the same date suggests a cluster of insider caution heading into the autumn.
