* Dollar, yen gain as fresh data rekindles economy worries
* Oil edges up toward $50 but mixed data curbs gains
* Bonds retreat as equities rise (Adds close of U.S. markets)

NEW YORK, April 16 (Reuters) - U.S. stocks jumped and bond prices fell on Thursday after a better-than-expected quarterly profit at JPMorgan and hopes Google's results would surprise on the upside after markets close boosted optimism and dulled the safe-haven appeal of Treasury debt.
Wall Street stocks surged in a late-afternoon rally as investors bet that technology earnings will beat expectations, lifting shares of Google Inc <GOOG.O>, Hewlett-Packard <HPQ.N> and International Business Machines Corp <IBM.N>.
The dollar and yen rose against the euro as economic data around the world reduced confidence the global economy will recover anytime soon. Oil edged higher toward $50 a barrel but gains were limited because of the mixed data.
China earlier posted its weakest three months of growth since quarterly records began in 1992, while weak U.S. housing data and record jobless claims reflected the tenacity of the downturn.
Also on Thursday, the International Monetary Fund said the global recession is likely to be unusually long and severe and the recovery sluggish because it sprang from a financial crisis. For details, see [
]But regional U.S. manufacturing data that pointed to a less drastic contraction gave investors some reason to cheer. European shares ended at a two-month high, boosted by cellphone maker Nokia <NOK1V.HE>, which said it saw signs of stabilizing demand.
Also boosting sentiment were stronger-than-expected quarterly results from Harley-Davidson Inc <HOG.N> that also pointed to some stabilization in consumer spending.
The motorcycle maker's shares rose 5.7 percent to $18.11, while Nokia's <NOK.N> U.S. shares soared more than 11 percent to $14.88.
"People are starting to feel that maybe there's a slight chance this is not just a bear market rally," said John O'Brien, senior vice president at MKM Partners LLC in Cleveland, referring to the market's 28-percent rebound since touching a 12-year closing low on March 9.
"People are anticipating a pretty good number from Google. They seem to like to under-promise and over-deliver," he said.
Google's results beat expectations, with its shares climbing above $400 a share for the first time since October.
Shares of Apple Inc <AAPL.O> shares closed 3.2 percent higher, while JPMorgan rose 2.1 percent and HP rose 5 percent.
JPMorgan Chief Executive Jamie Dimon said the bank could pay back "tomorrow" the $25 billion in taxpayer funds it received from the U.S. government in October, boosting sentiment.
"That's probably the most positive thing any investor could hear from them," said Rob Lutts, chief investment officer of Cabot Money Management in Salem, Massachusetts.
The Dow Jones industrial average <
> closed up 95.81 points, or 1.19 percent, at 8,125.43. The Standard & Poor's 500 Index <.SPX> rose 13.24 points, or 1.55 percent, at 865.30. The Nasdaq Composite Index < > climbed 43.64 points, or 2.68 percent, at 1,670.44.In Europe, the FTSEurofirst 300 <

Roche posted a 7 percent rise in sales and sounded a confident note for the full year. Roche shares gained 1.8 percent.
"We are getting a much better view in terms of what's happening at the corporate level," said Henk Potts, strategist at Barclays Stockbrokers.
"While it's not positive, it's certainly not as gloomy as many market participants had feared," Potts said.
U.S. and euro zone government bond prices fell after the upbeat corporate results boosted equities and cut the appetite for less risky fixed-income assets.
U.S. Treasury prices also fell after the Federal Reserve purchased fewer inflation-protected bonds than it has in recent operations, buying just $1.5 billion of the $15.6 billion submitted by dealers.
A contraction in U.S. factory activity in the mid-Atlantic region slowed in April, according to a survey by the Federal Reserve Bank of Philadelphia, helping push bond prices down.
The benchmark 10-year U.S. Treasury note <US10YT=RR> slid 20/32 to yield 2.84 percent. The 2-year U.S. Treasury note <US2YT=RR> fell 4/32 to yield 0.91 percent.

The euro <EUR=> fell 0.36 percent to $1.3171. Against the yen, the dollar <JPY=> slipped 0.05 percent to 99.34.
"The general theme is a slight rise in risk aversion that was triggered by the disappointing Chinese GDP data and soft euro-zone economic figures overnight," said Omer Esiner, forex market analyst at Ruesch International in Washington.
U.S. crude for May delivery <CLc19> rose 73 cents, or 1.48 percent, to settle at $49.98 a barrel.
