NEW YORK (CNNMoney) -- U.S. stocks are poised for a higher open Tuesday, after European Union leaders agreed to strengthen a financial firewall and sign a fiscal pact.
World markets rose, and in the United States S&P 500 ( ), Dow Jones industrial average ( ) and Nasdaq ( ) futures were about 0.4% higher. Stock futures indicate the possible direction of the markets when they open at 9:30 a.m. ET.
During their meeting in Brussels,on Monday, European Union leaders agreed to implement the European Stability Mechanism, a permanent rescue fund, in July. The €500 billion ESM was originally set to enter into force next year, when a temporary bailout fund expires.
The leaders of all but two members of the 27-nation EU also agreed to sign a fiscal pact, which was designed to prevent governments from running excessive deficits and racking up unsustainable debts.
But the first summit of the year ended without new solutions for the debt crisis in Greece. Without a deal with private-sector creditors, the country jeopardizes its access to bailout funds, and might not be able to make a €14 billion debt payment that's due March 20.
"There's positive news coming out of Europe, but it's still very tenuous with Greece," said Jeffrey Phillips, chief investment officer of Rehmann Financial. "Every time we see something positive there, we seem to see it reverse in four or five days."
U.S. stocks recovered most of their lost ground Monday afternoon, but struggled to pull out of the red as concerns over Greece continued to weigh on the market.
