A clear divide has opened up in recent insider activity. In Asia, a founding shareholder piled in. In the US, CEOs cashed out.
The biggest buy: Viva China Holdings — the vehicle of Li Ning founder Li Ning himself — has spent over $160M buying shares in Li Ning Co across multiple days in late August and early September. The filings, reported September 7, show purchases totalling nearly 94 million shares. This is a sustained, repeated bet by the founder's own holding company — not a one-time token buy.
The biggest sell: Medpace Holdings founder and CEO August Troendle filed sales repeatedly through August. Combined filings show he sold over $35M worth of stock in a span of days. The CFO and a director also sold. When a founder-CEO, CFO, and board member all sell at the same time, that's a cluster worth watching.
Comfort Systems USA CEO Brian Lane filed a $25.8M open-market sale on August 27. Corpay Chairman and CEO Ron Clarke sold on August 25.
On the biotech side, argenx founder-CEO Timothy Van Hauwermeiren filed a $21.1M sale on September 5, covering 20,000 shares traded September 3.
The contrast is stark. Asian insiders bought on dips. US executives trimmed near recent highs. Insider buys — especially repeated ones by founders — tend to carry more signal than sales, which can reflect diversification or pre-planned schedules.
