NEW YORK (CNNMoney) -- U.S. stocks are set to open in the red Tuesday, as investors await progress on Greek debt talks and wade through another batch of corporate results.
S&P 500 (), Dow Jones industrial average ( ) and Nasdaq ( ) futures were lower. Stock futures indicate the possible direction of the markets when they open at 9:30 a.m. ET.
Anxiety remains about the European debt crisis and, in particular, Greece's ongoing negotiations with representatives of private-sector creditors to reduce its debt burden.
A deal is a key condition for Greece to receive additional bailout funds from the European Union and International Monetary Fund. Without this financial support, Greece may not be able to make a €14 billion payment it owes on bonds that's due March 20.
"The primary impact of the Greek debt crisis is an overwhelmingly negative impact to and deflation of confidence in world markets," said Kevin Brungardt, chairman of RoundPoint Financial. "It is the poster country for a further worldwide pullback. People want to see a recovery and every bit of bad news stokes 'Chicken Little syndrome'."
