* GDP, jobless claims raise expectations of Fed tapering
* Euro at 1-month high vs dollar after ECB holds rate steady
* European shares end down on Fed views, deflation fears
NEW YORK, Dec 5 (Reuters) - Treasury yields hit three-month highs and U.S. stocks closed down for a fifth straight day on Thursday as robust economic and labor market data raised expectations of an imminent cutback in the Federal Reserve's stimulus.
With the U.S. jobs report for November due on Friday, caution gripped investors ahead of what is expected to be the most crucial data to indicate when the Fed would begin tapering its monthly purchases of $85 billion in Treasuries and mortgage-backed securities.
"There are still people interpreting that the door is still open for a December taper" by the Fed, said Sean Murphy, a Treasuries trader at Societe Generale in New York. The Fed will meet on Dec. 17-18, its last policy meeting of the year.
The Dow Jones industrial average ended down 68.26 points, or 0.43 percent, at 15,821.51. The Standard & Poor's 500 Index was down 7.78 points, or 0.43 percent, at 1,785.03. The Nasdaq Composite Index was down 4.84 points, or 0.12 percent, at 4,033.17.
The euro rose to a one-month high against the dollar after the European Central Bank left a key interest rate unchanged, disappointing some traders who had hoped for more aggressive easing measures in the euro zone.

In another sign of strength in the economy, the Commerce Department said gross domestic product grew at an annualized 3.6 percent rate in the third quarter, the fastest pace since the first quarter of 2012. It was a sharp revision from the 2.8 percent pace reported earlier and exceeded the 3.0 percent estimate of economists polled by Reuters.
"This data is spilling into a market that doesn't know how to react to good and bad (economic) news," said Drew Wilson, an analyst at Fenimore Asset Management in Cobleskill, New York.
Atlanta Fed President Dennis Lockhart downplayed the GDP number in a speech to bankers and business people on Thursday. "The strong third quarter doesn't make a trend and ... doesn't drive me to the conclusion that we've had a breakout in terms of growth," he said, citing "pretty low" ongoing estimates for fourth-quarter growth.
Other data offered a less rosy picture on the economy. New orders for factory goods fell 0.9 percent in October after a 1.8 percent rise in the prior month as demand for aircraft and capital goods weakened, suggesting some cooling in manufacturing.
