Uber's chief executive bought $10 million of his own company's stock on the open market on 10 September — and he was the second insider there to do it inside a week.

Dara Khosrowshahi bought 141,000 shares at $70.96. Six sessions earlier, on 4 September, Andrew Macdonald bought 70,000 shares across two filings at $75.65 and $76.44, for $5.31 million. Together the two purchases come to $15.31 million.

The prices are the detail worth holding onto. The first buyer paid about $76; the chief executive paid $70.96 six sessions later, roughly 7% lower. Insiders buying into a decline is a different pattern from insiders buying into strength, and it is the one that takes more conviction — the second buyer could see exactly what the first one paid.

Both are code P transactions: cash from a personal account at the market price. Not options exercised, not restricted stock vesting, not a grant. At a $148.2 billion company an executive's purchase changes nothing about the balance sheet, so the only thing it can carry is what the buyer thinks of the price.

What it does not settle is the next quarter. Chief executives buy into declines that keep going, and a single purchase — even a seven-figure one — is a statement about a price, not a prediction about a business.

Both buyers also split their purchases across more than one price rather than crossing a single block, which is what an ordinary open-market order looks like when it is worked through a session. Uber files these the same day it has to, so the record is close to the trade rather than a month behind it.

All figures are from SEC Form 4 filings via EDGAR, reviewed by InsiderBuying.com. Roles are as filed — Andrew Macdonald files in the catch-all officer category, not as chief executive or finance chief.
