GLOBAL MARKETS-Stocks gyrate on AI jitters, gold slides as US-Iran talks progress

By Stephen Culp

NEW YORK, Feb 17 (Reuters) - Wall Street stocks see-sawed on Tuesday, as investors continued to wrestle with the pros and cons of the artificial intelligence boom, while gold slid and crude dipped as nuclear talks progressed between the United States and Iran.

The three main U.S. stock indexes gyrated throughout the session with the recent tech selloff prompting some bargain hunting, while the dollar gained strength and gold slipped to a one-week low.

Worries that companies are over-investing in AI and the extent to which the nascent technology could disrupt labor markets have been contributing to investor jitters in recent weeks.

"The conversation about AI rose to the top of market concerns about two weeks ago, regarding the negative effect on employment in a broad variety of industries, and it's continuing," said Peter Tuz, president of Chase Investment Counsel in Charlottesville, Virginia. "There's a lot of validity in that AI will result in less demand for certain types of workers. It clearly has affected the tone of the market over the last couple of weeks."

Federal Reserve Governor Michael Barr said that "there might be serious short-term disruptions in the labor market" attributable to AI, even if the long-term gains to society could be quite favorable.

Turning to the subject of monetary policy, Barr said that the next interest rate cut might not occur "for some time" amid risks to the United States' inflation outlook.

The United States and Iran have reached an understanding regarding the "guiding principles" in continuing negotiations over their nuclear dispute, while stressing that a deal is not necessarily imminent, according to Abbas Araqchi, Iran's foreign minister.

"It's an optimistic starting point," Tuz added. "It's way too early to tell, but the fact that they're talking and haven't gotten more aggressive is positive."
