An NVIDIA independent director filed a cluster of sales totalling more than $410 million in early September, making it the standout insider story of the past month. Mark Stevens, a longtime board member and venture investor, sold roughly 2.1 million shares across several transactions on August 31 and September 2, with filings hitting SEC records on September 2. The sales were spread across multiple tranches, each in the 300,000-share range, at prices around $220 to $226. Stevens retains a large residual stake, but the scale of the disposal will draw attention given NVIDIA's elevated valuation after two years of near-vertical gains driven by AI chip demand. Taiwan's August export orders hit a record $103 billion, up 71% year-on-year per ORTEX Alt Data, with electronics a major component, context that underlines why chip stocks are closely watched by insiders and investors alike.
On the buying side, Uber President and COO Andrew MacDonald filed a $4.1 million open-market purchase on September 4, disclosed September 8. He acquired 54,325 shares at roughly $75.65. Discretionary open-market purchases by operating executives carry more weight than pre-planned sales; this is a positive signal from a senior operator.
In Hong Kong, the controlling holding company of Li Ning bought $67 million in shares on August 27, a substantial vote of confidence from the founding family in the sportswear group's near-term prospects.
