U.S. stocks tick down amid rate hike concerns

U.S. stocks retreated Tuesday as investors assessed the timing of the next interest rate hike by the Federal Reserve.

The Dow Jones Industrial Average fell 48.69 points, or 0.26 percent, at 18,454.30. The S&P 500 lost 4.26 points, or 0.20 percent, to 2,176.12. The Nasdaq Composite Index was down 9.34 points, or 0.18 percent, to 5,222.99.

Fed Vice Chairman Stanley Fischer said early Tuesday that it is impossible to say whether the next interest rate hike would be "one and done," according to media reports.

Fischer's comments were in line with remarks he and Fed Chairperson Janet Yellen made on Friday at a conference in Jackson Hole, Wyoming, indicating that the time to lift rates again was nearing.

"In light of the continued solid performance of the labor market and our outlook for economic activity and inflation, I believe the case for an increase in the federal funds rate has strengthened in recent months," Yellen said Friday.

Analysts said it is possible for the Fed to hike interest rates as soon as September. But about 71 percent of 62 economists surveyed by the Wall Street Journal this month believed that the Fed will wait until December to raise rates.

On the economic front, the Conference Board Consumer Confidence Index came in at 101.1 in August, up from 96.7 in July.

Overseas, European equities closed mixed Tuesday. German benchmark DAX index at Frankfurt Stock Exchange added 1.07 percent, while British benchmark FTSE 100 Index dipped 0.25 percent.

In Asia, Chinese stocks closed higher Tuesday, led by aviation and banking shares, with the benchmark Shanghai Composite Index rising 0.15 percent to 3,074.68 points. Enditem
