If you’ve invested in AI chip maker Nvidia, how do you know when to sell?
Nvidia CEO Jensen Huang made his first share sale of the year in June, cashing in 1.3 million shares to net $169 million, the most he’s gained so far in one month, Bloomberg reported on Wednesday.
Factoring in June’s sale, Huang has gained close to $1.1 billion from selling stock since January 2020. He’s not done yet, with U.S. Securities and Exchange Commission filings showing that he intends to keep cashing in this month.
As of June, Huang had a 3.8% stake in Nvidia, or over 934 million shares, making him the company’s largest individual stockholder.

From the start of this year, Nvidia executives and directors have sold shares collectively worth more than $700 million, per Bloomberg.
Nvidia has seen over 3,000% stock growth in the past five years, which may have elevated more than one long-term employee to “semi-retired” status based on stock grants alone.

Nvidia briefly became the most valuable company in the world in mid-June, with a market cap higher than $3 trillion.
Nvidia’s stock isn’t always stable, though. Last week, shares dropped 16%, and the company lost more than $500 billion in market cap over three trading days. The loss was more than the entire market cap of Samsung or Costco.
Nvidia stock rebounded, and its valuation, still over $3 trillion at the time of writing, is now only surpassed by Microsoft and Apple.
“The big question people have on this stock right now is just sustainability,” Bernstein Research senior analyst Stacy Rasgon told The Hill on Friday. “It’s just the numbers have gotten so big, so quickly, that you’ve got to wonder, can they continue?”
