Uber COO Buys $5M as Chairman Counters Institutional Exit

Uber Technologies President and COO Andrew Gordon MacDonald filed on 8 September, disclosing he purchased roughly $5.3 million worth of UBER shares on 4 September. The two tranches totalled 70,000 shares. Open-market purchases by operating executives carry strong signal. They are discretionary, not compensation mechanics.

MacDonald's move came as UBER trades at a market cap of $136 billion with short interest at just 2.4% of free float. Bears have little conviction here. The COO stepping in with personal cash adds a layer of confidence from inside the building.

Elsewhere, a split emerged at Turkish valve maker Burçelik Vana. Chairman Umit Gumus filed a purchase of $12.9 million on 7 September. On the same day, asset manager Bulls Portföy sold $13.6 million of the same stock. The chairman and a 10% institutional owner moved in opposite directions within hours. That kind of standoff is worth watching. The chairman's buy was discretionary and at scale relative to the company.

JPMorgan Chase filed disclosures covering several Hong Kong-listed names, including $85 million of selling in Kingdee International Software and $71 million in Sunny Optical Technology. These are bank custody and prime brokerage flows, not conviction trades, and carry limited signal on their own.

Note: the EDGAR Form 4 tables for US insiders were unavailable in this query environment. The Uber and Burçelik data come from ORTEX's vendor insider dataset, current to 8 September 2026. Fresh US SEC filings from October could not be retrieved.
