(AP) -- U.S. stock indexes edged higher in early trading Thursday, led by gains in technology companies. Big retail chains and other consumer-focused stocks were also among the gainers. Health care companies were among the laggards. Investors had their eye on Washington, where Federal Reserve chair Janet Yellen was testifying before Congress for the second day.
KEEPING SCORE: The Standard & Poor's 500 index gained 3 points, or 0.2 percent, to 2,447 as of 10:12 a.m. Eastern time. The Dow Jones industrial average rose 18 points, or 0.1 percent, to 21,551. The Nasdaq composite added 17 points, or 0.3 percent, to 6,278. The Russell 2000 index of smaller-company stocks slid 2 points, or 0.2 percent, to 1,422.
FED TALK: Yellen was appearing before a Senate committee, a day after she testified before a House panel. On Wednesday, she raised the possibility that the Fed would consider slowing the pace of its interest rate increases if inflation remained persistently below its target level. The remarks assuaged concerns among some traders that the Fed was raising interest rates too quickly in the face of stalling inflation and sluggish U.S. economic growth, setting off a broad market rally.
