NEW YORK: The S&P 500 and Nasdaq closed lower on Tuesday, weighed down by weak chip and megacap shares ahead of earnings from heavyweight tech companies this week, but the Dow managed modest gains.
Microsoft, seen by many as leading the artificial intelligence race, fell 0.89 per cent to US$422.92 ahead of its quarterly results. After the closing bell, the software maker dropped about 5 per cent after reporting results that missed expectations for quarterly growth in its Azure cloud-computing service.
Chipmaker Nvidia, regarded as a prime beneficiary of potential AI growth and the year's second best S&P 500 performer, tumbled 7.04 per cent to US$103.73, weighing on other chip stocks to pull the Philadelphia semiconductor index down 3.88 per cent.
Other megacap names such as Apple, Amazon.com and Meta Platforms, are all due to report earnings this week. Apple edged up 0.26 per cent to US$218.80, but Amazon slipped 0.81 per cent to US$181.71 and Meta shed 0.54 per cent to US$463.19 on valuation concerns.
"A lot of people are looking at artificial intelligence now and saying this is all great but I how do I make money on it," said Stephen Massocca, senior vice president at Wedbush Securities in San Francisco.
"Financially the companies are probably doing quite well, but the question is what are you paying for this? These are not cheap stocks and so you need to go into these things with your eyes open."

The small cap Russell 2000 gained 0.35 per cent and the S&P value 500 index advanced 0.52 per cent, buoyed by financials , which jumped 1.19 per cent to outperform the broader market. This extended a recent rotation out of more expensive stocks as the market has solidified expectations the Federal Reserve will cut rates this year on signs of moderating inflation.
Energy, up 1.54 per cent, and financials were the best performing of the 11 major S&P sectors while technology , down 2.2 per cent, was the weakest.
Megacap stocks fell last week on Tesla's disappointing results and Alphabet's higher expenditure forecast, prompting a broad-based market sell-off.

Several labor data releases are scheduled for this week, culminating in Friday's government payrolls report. On Tuesday, a Job Openings and Labor Turnover Survey pointed to 8.18 million job openings in June, compared to economists' expectation of 8 million.
