U.S. stocks open mostly higher, with gains led by tech-heavy Nasdaq

U.S. stocks opened mostly higher Tuesday, with gains led by the technology-heavy Nasdaq Composite, after a debt-ceiling deal was reached over the long holiday weekend honoring Memorial Day. The Nasdaq
COMP,
+0.49%
was up 1.1% soon after the opening bell, while the S&P 500
SPX,
+0.03%
gained 0.5% and the Dow Jones Industrial Average
DJIA,
-0.39%
traded down less than 0.1%, according to FactSet data, at last check. Tech shares rallied last week amid investor enthusiasm tied to artificial intelligence, with the Nasdaq advancing a fifth straight week in its longest win streak since the stretch ending in early February, according to Dow Jones Market Data. Meanwhile, the debt-ceiling agreement between President Joe Biden and House Speaker Kevin McCarthy still needs to pass Congress.
