U.S. stock index futures were slightly volatile in late trading on Sunday (March 17), with investors cautious ahead of the Federal Reserve meeting, but artificial intelligence company Nvidia's annual developer conference was also in the spotlight.。

The Wall Street Index fell, pulling back from record highs set in the previous two weeks, and enthusiasm among tech giants appears to be cooling, driven by enthusiasm for artificial intelligence, and a series of better-than-expected inflation data that also raised concerns about long-term higher interest rates that the Federal Reserve may suggest.。

S & P 500 futures up 0 as of 19: 04 Eastern time (23: 04 GMT).05%, to 5,185.50 points; Nasdaq 100 futures up 0.1%, to 18,071.0 points; Dow futures down 0.1%, to 39,126.0 point。

Federal Reserve in spotlight after high inflation。The market is now focused on the Fed meeting that ends this Wednesday。While the Federal Reserve is widely expected to leave interest rates unchanged, any signs of a rate cut will be closely monitored.。

Higher consumer and producer inflation data last week raised concerns that the Fed could send further hawkish signals at this week's meeting.。Federal Reserve officials have also been stressing that any possible rate cuts will be influenced by inflation trends, which have been stubbornly above the Fed's annual 2 percent target.。

Concerns about the Federal Reserve weighed on the Wall Street index last week, though the impact was lighter.。On Friday, the S & P 500 fell 0.7% to 5,117.09; Nasdaq composite down 1% to 15,973.17 points; Dow Jones industrial average closes down 0.5%, to 38,714.77 points。

Despite small weekly falls in the S & P 500 and Dow Jones Industrial Average, the Nasdaq fell 0 on big profit-taking by technology companies.7%。

Nvidia (NASDAQ: NVDA) is expected to release more AI leads at the GTC conference, which is also the company's first annual developer conference since the new crown outbreak。

Nvidia has been at the forefront of the AI-driven market surge over the past year, and the company is usually expected to launch a new flagship chip designed specifically for AI development.。CEO Renxun Huang will then deliver a keynote speech that may showcase Nvidia's next-generation artificial intelligence processor, which analysts expect to be named B100。

As a result of its AI efforts, Nvidia's value has grown significantly so far in 2023 and 2024, making it the third-largest Wall Street company by market capitalization after Apple Inc (NASDAQ: AAPL) and Microsoft Corp (NASDAQ: MSFT).。While that rise slowed last week, the GTC conference could be key to returning to growth for Nvidia and the larger tech sector.。
