All eyes are on Nvidia's stock, so what's been going on?

Market watchers would rather there be more diversification, having concerns seeing just Nvidia and a handful of other companies responsible for much of the S&P 500′s returns recently. They would prefer a market where many stocks are participating in the gains.

There’s been nearly insatiable demand for Nvidia’s chips to power artificial intelligence applications.

And the company has played a big role in the US stock market’s recent record runs, even as the economy’s growth slows under the weight of high interest rates.

But the AI boom is moving at such a rapid pace that it’s raised worries about a possible bubble in the stock market and too-high expectations among investors.

Still, investor concerns may be calming, as Nvidia Corp’s stock was up more than 5% in trading on Tuesday.

The rebound for Nvidia helped the Nasdaq composite rise and head toward its first gain in four days.

Derren Nathan, head of equity research at Hargreaves Lansdown, said in a statement that while Nvidia’s stock has declined in recent days, one must also look at the bigger picture.

“The shares have still gained 190% on a 12-month view, so it’s no surprise some investors are locking in some profits,” he said.

Nathan also isn’t concerned about potential wider spread implications.

“Although Nvidia has sneezed, the wider market hasn’t caught a cold with a mixture of less extreme movements in both directions for the rest of the Magnificent Seven,” he said.

The Magnificent Seven, which include Alphabet, Amazon, Apple, Meta Platforms, Microsoft, Nvidia and Tesla, are a small group of stocks responsible for a big chunk of the US stock market’s total return.

Investors may also be welcoming a better-than-expected consumer confidence reading and a solid job market.

America’s employers added a strong 272,000 jobs last month, a sign that companies are still confident enough in the economy to keep hiring despite persistently high interest rates.

Long term, the market may remain upbeat on Nvidia’s prospects.

Analysts estimate that the company’s revenue for the fiscal year that ends in January 2025 will reach $119.9 billion — about double its revenue for fiscal 2024 and more than four times its receipts the year before that.
