Wall St. falls as dollar advances

U.S. stock indices fell on Friday after a week of wavering as the dollar strengthens against major rivals, and after negative comments from ECB president yesterday.

Dollar rose to an eight-month high against main rivals, heaping pressure on shares of American exporters as dollar's rise weighs on their competitiveness abroad. 

Remarks made by European Central Bank President Mario Draghi continues to weigh on stocks, as he ruled out suspending the stimulus program as expected. 

The dollar index, tracking the greenback's performance against a basket of six major peers, rose to 98.72 from the opening of 98.30, with an intraday low at 98.30, and an eight-month high at 98.75, heading for the fourth weekly profit in a row. 

Standard and Poor's 500 shed 0.50%, or 10.64 points to 2,130.70, while Dow Jones gave up 0.53%, or 96.94 points to 18,065.86. 

Tech-heavy NASDAQ inched down 0.04%, or 2.06 points to 5,239.77.
