Wall Street stocks finished lower Friday in light pre-holiday trade after Federal Reserve Chair Janet Yellen said the plan to raise interest rates this year was on track.
The Dow Jones Industrial Average dropped 53.72 points (0.29 percent) to 18,232.02.
The broad-based S&P 500 fell 4.76 (0.22 percent) to 2,126.06, while the tech-rich Nasdaq Composite Index slipped 1.43 (0.03 percent) to 5,089.36.
Yellen said delaying a move to raise interest rates "would risk overheating the economy." However, she also warned that the US economy continues to show weakness, with significant job market slack not reflected in the 5.4 percent jobless rate.
