NEW YORK/LONDON, Dec 10 (Reuters) - World stocks broke five consecutive days of losses on Thursday as U.S. economic reports supported the theme of stronger growth in 2010, while the euro slumped on fiscal worries.
European stocks rebounded strongly as some investors reassessed risks from the region's more vulnerable economies.
Wall Street shares rose after the government said the U.S. trade deficit unexpectedly shrank in October, indicating businesses gained traction off the weaker U.S. dollar. In another report, the four-week average for jobless claims fell a 14th week, even as initial claims edged higher in the last period.
Despite gains on Thursday, investors globally have been protecting profits and taking few risks before year-end. World stocks as measured by the MSCI soared about 76 percent through last week from March lows.
"You've had a tremendous movement this year, and you'll see a continued battle between people putting away whatever they've earned this year in profits and investors still thinking there might be more room to run," said Rick Meckler, president of LibertyView Capital Management in New York.
Rallies have been capped since November as investors debate the prospects of growth in the U.S. amid expectations of high unemployment, and in a climate of concern over creditworthiness of various troubled economies.
Ratings agency Standard & Poor's on Wednesday warned that Spain risks a debt downgrade in two years if the government does not take tough action on its fiscal deficit.
Fitch Ratings has already downgraded Greece, while Moody's cut the ratings of six Dubai-linked issuers after concluding that no "meaningful" government support would be provided to top firms such as DP World.
MSCI's all-country world stock index <.MIWD00000PUS> increased 0.37 percent to 295.11, having lost about 3 percent since hitting a one year-high a week ago.
The Dow Jones Industrial Average <.DJI> rose 68.40 points, or 0.66 percent, to 10,405.45. The Standard & Poor's 500 Index <.SPX> climbed 6.89 points, or 0.63 percent, to 1,102.84 and the Nasdaq Composite Index <.IXIC> increased 13.29 points, or 0.61 percent, to 2,197.02.
The pan-European FTSEurofirst 300 <.FTEU3> rose 1.04 percent.
REBOUNDING DOLLAR
The U.S. dollar gained against the euro as fiscal problems in the euro zone increased safe-haven demand for the greenback, overshadowing a narrower-than-expected U.S. trade deficit for October and some improvement in U.S. jobless claims.
"Increased sovereign risk associated with the euro will see some headwinds associated with the euro," said Omer Esiner, senior market analyst at Travelex Global Business Payments in Washington.
The U.S. Dollar Index <.DXY> edged higher by 0.08 percent
to 76.098. The euro
The Australian and New Zealand dollars both rose on growing expectations of higher interest rates.
U.S. Treasury debt prices fell, pushing 30-year yields to four-week highs at 4.47 percent as investors prepared to buy $13 billion of the long-term debt. Yields on benchmark 10-year Treasury notes rose 0.06 percentage point to 3.49 percent.
