Founders Cash Out as Uber COO Bets Big

Insiders at several high-profile companies made striking moves in early September. The filings — disclosed this past week — reveal a heavy lean toward selling, with one notable exception.

Elastic founder and CTO Shay-Shalom Banon filed sales totalling more than $44M on September 2. He sold at prices between $89 and $98 per share across three days. Elastic's CLO and Chief Accounting Officer also filed smaller sales in the same window — a cluster of three executives cashing out simultaneously. The $8.8B search-analytics company has seen its stock run hard this year.

argenx CEO Timothy Van Hauwermeiren filed a $21M sale on September 5, trading 20,000 shares at $908 each. The Belgian biotech's CMO and General Counsel filed their own sales within days. The three exits total roughly $24M and span the company's entire C-suite.

Against that wave of selling, Uber stands out. President and COO Andrew MacDonald filed a $4.1M open-market purchase on September 8. He bought 54,325 shares at an average of $75.65. Open-market buys from operating executives are rare. MacDonald spent real cash on Uber stock — a notably bullish signal for the $146B ride-hailing giant.

Elsewhere, JPMorgan Chase disclosed it cut its stake in Kingdee International by over $84M and trimmed positions in several other Hong Kong-listed names around the same date.

The Elastic and argenx sales are worth watching. Volume and timing suggest coordinated, possibly pre-planned disposals. Investors should check whether 10b5-1 plans were disclosed in the underlying filings before drawing conclusions.
