Insiders Dump as NVDA Director Sells $300M+

An NVDA board member filed a string of large sales in early September. Independent Director Mark Stevens reported selling more than $300 million worth of Nvidia shares across several transactions between August 31 and September 2, with individual trades ranging from $30 million to $98 million. The filings hit SEC records on September 2. Stevens is not a company executive, and no 10b5-1 plan flag was noted in the available data, making the cluster worth watching.

Elsewhere, TPC Executive Chairman Ronald Tutor filed two sales totalling nearly $197 million in Tutor Perini shares, both tied to trades on August 31 and reported on September 2. At that scale, it ranks among the largest US construction-sector insider exits on record in recent months.

MSFT CEO Satya Nadella filed a $36 million sale on September 1, covering a trade made August 31. Nadella sells periodically under disclosed arrangements, so this carries a weaker signal than a discretionary move.

Outside the US, the CEO of South Korean robotics firm ROBOTIS filed a $75 million sell on September 8. China-listed Servyou Software's CEO filed a $108 million purchase on September 2, a rare C-suite buy of that size in the Chinese software sector.

Note: the vendor insider dataset used here runs to September 8, 2026. More recent filings from the SEC EDGAR first-party tables were not accessible in this session and may contain fresher activity.
