Nvidia stock started the week on a high note as CEO Jensen Huang appeared to reaffirm his company’s commitment to the Chinese market.

Nvidia CEO Jensen Huang has caught up to Berkshire Hathaway’s Warren Buffett in net worth, according to analysis from Fortune and Bloomberg.

Nebius is currently the best stock that Nvidia owns. The company flew under the radar earlier this year because it was listed on the Nasdaq Stock Exchange just recently (in October) after a nearly three-year hiatus. The Russian tech giant Yandex, which was delisted due to sanctions after Russia invaded Ukraine, formerly owned Nebius' assets.
