NEW YORK, July 29 (Reuters) - Global stocks fell on Thursday as concerns about the recovery offset robust earnings, although the euro surged to a 12-week high against the dollar on better-than-expected European economic data.
Stocks erased initial gains, encouraging investors to buy safe-haven U.S. Treasuries, as investors worried that an expected U.S. economic slowdown will eventually hurt earnings.
That fear overshadowed a batch of strong quarterly earnings from major companies, including Exxon Mobil Corp <XOM.N>, Rolls Royce Plc <RR.L> and BAE Systems Plc<BAES.L>.
Government data showing that U.S. initial jobless claims fell more than expecteed last week gave only temporary support to Wall Street. [
]"Most of the numbers kicked in a lot better, but there is still a lack of confidence in the sustainability of economic growth and the sustainability of the earnings stream being extended into 2011," said Heino Ruland, a strategist at Ruland Research in Frankfurt.

EURO BRIEFLY POPS ABOVE $1.31
The euro climbed to a 12-week high against the dollar, however, as month-end demand and supportive data helped push the single currency above a key technical barrier.
The advance of the euro started early in the session after a jump in euro-zone economic sentiment to a 28-month high and a decline in German unemployment. [

"Economic resilience in Europe, particularly in Germany, despite the formidable sovereign credit headwinds, continues to fuel an unwinding of bets against the euro and push it higher across the board," said Omer Esiner, chief market analyst at Commonwealth Foreign Exchange in Washington, D.C.
