Uber COO Buys $5M as NVDA Director Dumps $400M

UBER President and COO Andrew Gordon MacDonald filed purchases worth roughly $5.3M on 8 September, buying 70,000 shares at around $75 on 4 September. Open-market buys by C-suite executives carry weight. MacDonald's move stands out as one of the cleaner bullish signals in recent weeks.

At the other end of the ledger, NVDA Independent Director Mark Stevens has been selling heavily. Filings show he sold over $400M in shares across multiple tranches between 31 August and 2 September, offloading more than 1.8 million shares in five separate transactions. The pace of selling is striking, though frequent insider sales at NVIDIA have been a recurring pattern over the past year.

Among non-US names, JPMorgan Chase disclosed sizable changes as a 5% owner in several Hong Kong-listed stocks. It sold $85M in Kingdee International Software and $71M in Sunny Optical, while buying $27M in Huaneng Power.

A private equity exit was also notable: PENM IV Germany sold $23M worth of AST, the Vietnamese airport services group, on 7 September.

The Uber buy is the freshest discretionary signal in the dataset. MacDonald paid market prices with no 10b5-1 plan disclosed, which makes it a stronger read on his view of the company's near-term prospects than a scheduled sale would be.
