U.S. stock indexes rose to more records Wednesday after tech companies talked up how much of a boost they’re getting from the artificial-intelligence boom. The S&P 500 climbed 0.6% to add to what’s set to be one of its best years of the millennium.

In the bond market, Treasury yields held relatively steady after a report showed U.S. employers were advertising slightly more job openings at the end of October than a month earlier. Continued strength there would raise optimism that the economy could remain out of a recession that many investors had earlier worried was inevitable.
