U.S. stocks rose following an encouraging report on inflation that could help the Federal Reserve keep cutting interest rates next year.

A strong profit report from Micron Technology also helped AI stocks halt their sharp slides on Thursday, at least for now. The S&P 500 gained 0.8% to break a four-day losing streak. The Dow Jones Industrial Average added 0.1%, and the strength for tech stocks sent the Nasdaq composite up 1.4%.

Treasury yields eased in the bond market after the report showed U.S. inflation was less bad last month than economists expected.
