Nvidia briefly dethroned Apple today as the world's most valuable publicly traded company.
Driving the news: The stock soared in early trading, following the Dow Jones Indices' decision Friday that the chip giant would replace Intel in the Dow Jones Industrial Average later this week. It gave up most of those gains to close up 0.5%.
The intrigue: This year's tight race among Apple, Nvidia and Microsoft in market value reflects the continued momentum of the AI trade.
