Directors Cash Out as NVDA Director Dumps $411M

An NVIDIA board member has been one of the most active sellers in recent filings. Mark Stevens, an independent director at the $4.4 trillion chipmaker, filed disclosures showing he sold roughly 1.85 million shares across seven transactions between 31 August and 2 September, totalling approximately $411 million. That is a large exit even by Silicon Valley standards.

The scale dwarfs other activity in the same period. NVIDIA's General Counsel Timothy Teter also filed sales worth around $6.5 million on 31 August, adding to the pattern of outgoing stock at the top. Short interest in NVDA sits at just 1.3% of free float, so this is not a squeeze story. It is a pure signal-watching exercise: board-level sales of this size tend to draw attention regardless of company performance.

Elsewhere, argenx CEO Tim Van Hauwermeiren filed a sale of 20,000 shares worth $21 million on 5 September. Four insiders at the Belgian immunology company sold in the same two-week window, with combined proceeds topping $29 million.

At WuXi XDC, parent company WuXi AppTec offloaded 53.5 million shares worth $500 million on 31 August, filed 4 September. The biotech's COO Jerry Zhang also sold roughly $3.4 million in shares the same week. That combination of parent-company and C-suite selling arriving together is worth watching.

On the buying side, Shenzhou International Executive Chairman Ma Jianrong spent $25.8 million buying 5.6 million shares on 1 September. At Post Holdings, Chairman Emeritus William Stiritz sold $23.4 million worth of stock. Post carries a notably elevated short interest of 16.5% of free float.

Coherent Corp saw eight insiders file sales totalling $15.7 million, with no offsetting purchases recorded.
