Most US stocks were rising on Thursday after the latest update on the job market suggested the Federal Reserve may feel less pressure to hike interest rates. But more swings for chip stocks and other winners of the artificial-intelligence boom are keeping indexes mixed.

The S&P 500 fell 0.3 per cent, even though two out of every three stocks within the index were rising. The Dow Jones Industrial Average was up 329 points, or 0.6 per cent, as of 12:30 p.m. Eastern time, and the Nasdaq composite was 1.1 per cent lower after erasing an early gain.

Stocks broadly got some help from easing Treasury yields in the bond market, which fell after a report from the US government said employers added 57,000 jobs to their payrolls last month. That’s growth, which is good for the economy, but it was also short of the 100,000 jobs that economists expected and a slowdown from May’s hiring pace.
