Roundup: U.S. stocks edge down amid Yellen's testimony

U.S. stocks reversed early gains to end slightly lower Wednesday, as investors digested Federal Reserve Chair Janet Yellen's remarks delivered in the first of her two-day Congressional testimony.

The Dow Jones Industrial Average fell 3.41 points, or 0.02 percent, to 18,050.17. The S&P 500 lost 1.55 points, or 0.07 percent, to 2,107.40. The Nasdaq Composite Index decreased 5.95 points, or 0.12 percent, to 5,098.94.

The Fed is on track to raise interest rates later this year, as most Fed officials expect the economy to continue to gain growth momentum over the remainder of this year, said Yellen in her testimony Wednesday.

Low oil prices and ongoing employment gains should continue to bolster consumer spending, while financial conditions generally remain supportive of growth. In addition, the highly accommodative monetary policies in other countries should work to strengthen global growth. Those factors would support the U.S. economy to continue expansion, Yellen said.

Yellen's optimism appeared to be supported by the Fed's Beige Book and the upbeat economic data.

According to the Beige Book released Wednesday afternoon, all 12 Federal Reserve Districts indicated that economic activity expanded from mid-May through June.
