Stocks trimmed losses to end little changed on Friday, as investors saw dips in the market as an opportunity to buy into what has been a strong first month of 2012.

 

The Dow posted its first weekly loss this year, hurt Friday as Chevron Corp (CVX.N) announced earnings that were below Wall Street's estimates and Procter & Gamble Co (PG.N) cut its full-year profit forecast because of the strong dollar.

 

But the emergence of late-day buyers was viewed positively as major averages have methodically climbed through January. This week's news that the Federal Reserve intends to keep interest rates low through late 2014 added a jolt of demand that could extend the rally.

 

"Investors are almost welcoming these little dips, jumping in when they can to join this rally. At this point, they are rationalizing anything they can to get in," said James Dailey at TEAM Financial Management LLC in Harrisburg, Pennsylvania.

The Dow Jones industrial average .DJI was down 74.17 points, or 0.58 percent, at 12,660.46. The Standard & Poor's 500 Index .SPX was down 2.11 points, or 0.16 percent, at 1,316.32. The Nasdaq Composite Index .IXIC was up 11.27 points, or 0.40 percent, at 2,816.55.

 

For the week, the Dow fell 0.5 percent, the S&P was up 0.1 percent and the Nasdaq rose 1.1 percent.

 

Friday's losses were limited as U.S. Federal Reserve statements this week and economic data kept investors alert for the possibility of another round of monetary stimulus known as quantitative easing, or QE3.

 

"Out of what the Fed said, you can expect some negative numbers because the Fed obviously saw what the GDP numbers are and they anticipate a slowdown," said Sean Kraus, chief investment officer at CitizensTrust in Pasadena, California.

 

If the Fed does resort to QE3 to stimulate growth, investors "don't want to be caught flat-footed and be out of risky assets," Kraus said.
