Uber COO Buys Big as Activist Circles General Dynamics

The most striking US insider move in recent filings came from UBER. Andrew MacDonald, President and Chief Operating Officer, filed on September 8 that he bought $4.1 million worth of Uber shares on September 4. He paid roughly $75.65 per share and acquired 54,325 shares in an open-market purchase. The trade was discretionary, carrying no 10b5-1 plan flag, which makes it a stronger signal of personal conviction. The buy lands just as the FTC is reported to be demanding information from Uber on personalised pricing strategies, a headline that added regulatory noise to the stock.

Uber's short interest sits at just 2.4% of free float, so this is not a short-squeeze setup. It reads as a straightforward vote of confidence from an executive who knows the business from the inside.

At GD, the picture is different. Activist investor Longview is reported to have taken a stake, with analysts cutting price targets ahead of the company's Q3 earnings print. GD carries a market cap of $95.9 billion and bears have little skin in the game at 0.8% short interest, but an activist crossing the 5% threshold would be a meaningful escalation. Stakes disclosed in Schedule 13D filings reflect positions as last disclosed and may shift without a further filing.

Full EDGAR Form 4 transaction data was not available in this environment, limiting granularity on the GD insider activity. The Uber COO trade remains the clearest and freshest signal from disclosed filings.
