NEW YORK (CNNMoney) -- U.S. stocks edged higher Wednesday as investors remained focused on Greece, where the government is scrambling to secure more bailout funds and avoid a default.
The Dow Jones industrial average () rose 6 points, or less than 0.1%, to end at 12,884. The S&P 500 ( ) added 3 points, or 0.2%, to 1,350. The Nasdaq ( ) rose 12 points, or 0.4%, 2,916.
Given the lack of U.S. economic data Wednesday, investors continued to monitor developments in Greece, where talks on austerity reforms have been delayed several times this week.
Greek Prime Minister Lucas Papademos is meeting with the leaders of the three political parties that make up his interim government. The officials are discussing a draft of proposed spending cuts, including layoffs and pension reforms, that are a precondition for Greece to receive more bailout money.
Greece needs to finalize the program soon to pave the way for a second bailout of €130 billion from the European Union, International Monetary Fund and European Central Bank. Without these funds, Greece could miss a €14.5 billion bond redemption in March.
Finance ministers from the 17 nations that use the euro currency will meet Thursday to discuss the situation in Greece, according to a spokesman for Eurogroup president Jean-Claude Juncker.
Meanwhile, Greece is also negotiating with its creditors in the private sector over a writedown and debt exchange. There were conflicting reports on the ECB's willingness to participate in a restructuring of the Greek bonds it holds.
"Everyone is waiting for Greece to accept the austerity program and move ahead," said Peter Cardillo, market strategist at Rockwell Global Capital. "It's just a question of time."
Cardillo said stocks could pull back once an official agreement is reached. But eliminating the threat of a "disorderly default" will ultimately help the market move higher, he added.
"The market has discounted the fact that Greece is headed for an orderly default, which takes the pressure off the euro and diminishes the fear factor," said Cardillo.
U.S. stocks moved higher Tuesday on optimism about a Greek debt deal.
