Top 10 Q3 insider stock sellers led by Nvidia’s Stevens, Jeff Bezos

Billionaire venture capitalist and Nvidia (NVDA) director Mark Stevens led insider selling in the third quarter, as the chipmaker’s valuation neared its cheapest level in more than a decade, with other AI-linked billionaires also among the top sellers.

The top 10 list included Arista Networks (ANET) CEO Jayshree Ullal and Amazon.com (AMZN) founder Jeff Bezos, according to a Bloomberg News report, citing Washington Service, which tracks insider buying and selling.

While AI insiders made up nearly all of the top sellers in the second quarter, last quarter saw executives with health and biotech companies, including BeOne Medicines, United Therapeutics, and Illumina, selling off stocks at a rapid clip as well, the report showed.
