NEW YORK (Reuters) -World stock indexes dropped on Thursday, with the Nasdaq ending more than 2% lower after Meta Platforms and Microsoft (NASDAQ:MSFT) warned of rising costs for artificial intelligence, while the dollar weakened slightly after U.S. data did little to suggest a change to Federal Reserve policy.
The earnings reports added to concerns among investors that the pay-off for heavy spending on AI may take longer than many had hoped.
Shares of Facebook (NASDAQ:META) owner Meta were down 4.1% while Microsoft was 6% lower, with both weighing on the Nasdaq and S&P 500.
"Much of the adjustment in the market is the forward expectations," said Howard Chan, chief executive officer of Kurv Investment Management in San Francisco.
But "there are a lot of reasons to think that good earnings will continue," he said. "We still hold the thesis that infrastructure around AI will still do well."
After the closing bell, shares of Amazon.com (NASDAQ:AMZN) were up 4.5% after it posted third-quarter profit and sales that beat Wall Street estimates, while Apple shares (NASDAQ:AAPL) eased 2% following its outlook.
Amazon ended the regular session down 3.3% while Apple ended down 1.8%.
Early on Thursday, data showed U.S. consumer spending increased slightly more than expected in September, putting the economy on a higher growth trajectory heading into the final three months of the year.
Another U.S. report showed the employment cost index (ECI), the broadest measure of labor costs, rose 0.8% in the third quarter. That was the smallest gain since the second quarter of 2021 and followed an unrevised 0.9% increase in the second quarter.
The dollar also came under pressure against the yen after the Bank of Japan took a less dovish tone than expected, while the euro was stronger after data showed the bloc's inflation accelerated more than expected in October, bolstering the case for caution in European Central Bank interest rate cuts.
The dollar index, which measures the greenback against a basket of currencies, fell 0.2% to 103.88, with the euro last 0.04% higher against the dollar at $1.0859. Against the Japanese yen, the dollar was down 0.8% at 152.18 yen.
