Investors take a breather

NEW YORK (CNNMoney) -- U.S. stocks were poised to open slightly lower Friday, as investors take a breather after four consecutive winning days.

Dow Jones industrial average (INDU), S&P 500 (SPX) and Nasdaq (COMP) futures were all lower ahead of the opening bell. Stock futures indicate the possible direction of the markets when they open at 9:30 a.m. ET.

"Going into the weekend, anyone who has made money over the last couple days is probably happy to take some of that risk off the table," said Manoj Ladwa, a senior trader at ETX Capital.

U.S. stocks closed higher Thursday as banks led the market higher, following a coordinated effort by five central banks to help ward off a credit crisis in Europe.

The European Central Bank, the U.S. Federal Reserve and three other major central banks agreed to step in to boost dollar liquidity for banks in Europe.

The move comes amid signs of a pullback in bank-to-bank lending, as European Union officials struggle to resolve long-standing sovereign debt issues.

Finance ministers began meetings Friday in Poland, as they sought to shore up the region's most vulnerable economies -- a development that sparked optimism across the continent.

European stocks were broadly higher in morning trading. Britain's FTSE 100 (UKX) ticked up 1%, the DAX (DAX) in Germany rose 2.1% and France's CAC 40 (CAC40) increased 0.7%.

But of course, Europe's underlying debt issues remain, and a lasting solution will be difficult to hammer out.

"Any optimism could be fairly short lived," Ladwa said. "I don't think anyone is expecting the finance ministers to come up with a real concrete solution."
