NEW YORK, Dec 16 (Reuters) - U.S. stocks rose and Treasury prices held steady on Thursday after stronger-than-expected housing and regional factory data showed improving growth.
The euro edged lower against the dollar after European leaders signaled markets may not have seen the last of euro zone debt woes. In addition, Moody's said it may cut Greece's credit rating, which is already rated as "junk," if the country did not stabilize its finances.
Yields on U.S. Treasuries spiked briefly to seven-month highs after the U.S. data before declining. The benchmark 10-year U.S. Treasury <US10YT=RR> edged up 5/32 in price, yielding 3.50 percent.
"The data turned Treasuries around and as U.S. rates backed up, the dollar went with them," said Brian Dolan, chief strategist at Forex.com in Bedminster, New Jersey.
November housing starts rose slightly and weekly jobless claims came in line with expectations, suggesting the U.S. economic recovery is gaining traction. [

"The risk of contagion continues to play on investors' minds and that is certainly one of the biggest macro risks that you can point to as you look towards 2011," said Henk Potts, equity strategist at Barclays Wealth.
"But the corporate picture still looks very bright, the trend towards higher profits continues and public policy should remain shareholder-friendly. The name of the game is to try and hold onto the gains seen over the past couple of weeks."
EURO ZONE CREDIT RISKS EYED
Government debt yields for Spain, Portugal and Italy edged higher after bidders demanded a high premium for their cash from Spain in its final bond auction of the year.
Spain sold 2.4 billion euros in 10-year and 15-year bonds, in a key test of investor appetite for euro zone peripheral debt. Moody's said on Wednesday it may cut the country's rating and raised concern over its ability to manage its fiscal affairs. [
