NEW YORK (CNNMoney) -- U.S. stocks were set to open little changed, as investors keep an eye on Europe and weigh several key U.S. economic reports.
Dow Jones industrial average (), S&P 500 ( ) and Nasdaq ( ) futures straddled the breakeven point, though they turned slightly lower after two key U.S. economic reports. Stock futures indicate the possible direction of the markets when they open at 9:30 a.m. ET.
Worries remain heightened about Spain, after rating agencies Moody's and Egan-Jones both downgraded Spain on Wednesday. Moody's, which left Spain's rating just above junk status, warned that it is at risk of additional downgrades. It cited concern about Spain's debt load, its bleak economic prospects and its access to credit in private markets.
The struggling country recently requested up to €100 billion from the European Union to recapitalize its ailing banks. But with the higher borrowing costs, investors are worried the country will need even more help.
"Unless the Europeans come up with a policy response soon, it's looking increasingly like Spain will need a (government) bailout on top of support for the banks," said Nick Stamenkovic, fixed income strategist at RIA Capital Markets in Edinburgh. He estimated the government could need €50 billion.
The yield on 10-year Spanish bonds peaked at 7.02% early Wednesday according to TradeWeb -- the highest level since the euro was introduced in 1999. The same level signaled the need for bailouts in other European countries earlier in the crisis, but Spanish yields slid to 6.97% later Wednesday morning.
Investors are increasingly worried about a worsening situation in Italy, which is an even larger economy. It was able to sell €3 billion of its 3-year bonds, and an additional €1.5 billion of the 10- and 15-year debt at an auction Thursday. But it had to pay significantly more than at its previous auction, with the yield on the 3-year bonds rising to 5.3% from 3.9% in May.
"Italy is clearly being caught up the contagion that is affecting Spain," Stamenkovic said. "But there's a bit of relief that they did their targets. Yields are off their earlier highs."
