Nvidia announced on Wednesday a profit of $45.19 billion (€38.8 billion) in the first fiscal semester, marking a year-over-year increase of 43.6%.
Sales of semiconductors, the foundation of the artificial intelligence (AI) industry, fell slightly short of expectations.
The announced results were eagerly awaited, as Nvidia has become a barometer of AI growth over the past two years, a period that has propelled the stock market to historic highs.
In recent weeks, however, several research reports and comments from key industry figures have heightened concerns about the potential overvaluation of AI.
Nvidia’s results may fuel these concerns, as sales of processors—an essential component for powering data centers worldwide—appear to be slowing faster than investors anticipated.
As a sign of cooling investor sentiment toward Nvidia, its stock price was falling by about 3% in after-hours trading.
On Wednesday, the New York Stock Exchange closed higher, with the Dow Jones gaining 0.32%, the tech-heavy Nasdaq rising 0.21%, and the S&P 500 advancing 0.24%, allowing it to set a new closing high at 6,481.40 points.
