Alibaba's two most senior insiders bought its stock on the open market in late August, inside 48 hours of each other.

Chairman Joe Tsai, who files as a director, bought 720,000 shares on 24 August for $10.29 million, then another 720,000 on 25 August for $10.42 million. Chief executive Wu Yongming bought 350,000 shares on 24 August for $4.98 million. Together: 1.79 million shares and $25.69 million, in three open-market purchases across two sessions.

There is a trap in these filings that catches screens and spreadsheets alike. The prices on them — $14.24, $14.29 and $14.47 — are per ordinary share, the Hong Kong-listed line. One American depositary share represents eight ordinary shares, so the ADS-equivalent price is roughly $114 to $116. Compare the filing price against the New York quote without that conversion and the position appears to be up several hundred percent, which is the kind of error that turns a real signal into a bad one.

What makes the purchases worth noting is what they are, not what they predict. These are code P transactions: cash out of a personal account at the market price, not options exercised, not shares vesting, not a grant. That is the narrowest and most deliberate category of insider activity, and it is the only one that costs the filer something.

The pattern matters too. Two of the most senior people at the same company, buying within a day of each other, is a cluster rather than a solo top-up — the shape that is hardest to explain by personal liquidity alone.

What it is not is a forecast. Chairmen and chief executives buy into declines that continue, and a purchase tells you about conviction at a price, not about the next quarter. For a company of this size, $25.69 million is also a small fraction of either insider's holding.

All figures are taken from SEC Form 4 filings via EDGAR, reviewed by InsiderBuying.com. Share counts and dollar values are as filed; the per-share prices are in ordinary shares, as noted.
