Uber COO Buys Big While Nvidia Director Exits

Uber President and COO Andrew MacDonald filed a $4.1 million open-market share purchase on 8 September, one of the most significant discretionary buys reported in recent weeks. The trade covered 38,000 shares at an average of around $108. Open-market buys by operating-level executives carry strong signal. MacDonald has no disclosed 10b5-1 plan covering this purchase. Uber's stock is down 19% year-to-date, and analysts still see 51% upside to their consensus target price.

The contrast with NVIDIA is stark. A board director filed the sale of $411 million worth of NVIDIA shares last week, a disposal large enough to draw widespread attention. No 10b5-1 plan detail has yet been confirmed from the filing. OpenAI was reported this week to be diversifying chip purchases toward Google, adding a note of caution for the stock.

Elsewhere, JPMorgan Chase disclosed the sale of approximately $85 million worth of shares in Kingdee International Software and $71 million in Sunny Optical, both filed on 8 September and covering trades dated 2 September. These are institutional-threshold filings rather than management-conviction trades, but the scale is notable.

On the buy side, Korean holding company Netmarble filed three consecutive days of purchases in COWAY, totalling close to $6 million across 3 to 7 September, pointing to deliberate accumulation at the major-shareholder level.

The most active insider date in the dataset is 8 September. Readers should note that vendor data for US names can lag; ORTEX's own SEC EDGAR filings remain the primary source for US insider verification.
