NEW YORK, April 30 (Reuters) - The dollar reversed early gains to trade lower against most major currencies on Thursday as trading thinned ahead of the May Day holiday through much of Europe.
The dollar had climbed in early trade, helped by month-end flows as investors who had been betting against the dollar were forced to buy greenbacks as the release of some positive U.S. economic data suggested the economy will recover later this year.
But as European trading desks began to close for a long weekend, those gains evaporated.
"We have seen the movements we are going to see for this week," said Joseph Trevisani, chief market analyst at FX Solutions in Saddle River, New Jersey.
The euro was last down 0.1 percent at $1.3252 <EUR=>, after earlier climbing as high as $1.3384.
A rise in euro zone unemployment to 8.9 percent in March from an upwardly revised 8.7 percent in February underlined the view that the euro zone economy remains weak. Other data showed that euro zone inflation remained at a record low of 0.6 percent year-on-year in April
The dollar was 1.3 percent higher against the yen at 98.26 yen <JPY=> but 0.9 percent lower against the Canadian dollar at C$1.1938 <CAD=>. Sterling climbed 0.3 percent to $1.4811 <GBP=>.
Earlier, the dollar had climbed on expectations the U.S. will recover first, with investors sending the U.S. stock market higher. The benchmark Standard & Poors 500 index <.SPX> was on track for the best month since December 1991 at current prices.
U.S. weekly jobless claims decreased in the latest period even as continued claims notched a fresh record high, a sign some investors took as stabilization of the labor market. A separate report showed business activity in the U.S. Midwest contracted at a less severe rate than expected in April.
"A lot of what's driving the market today is month-end fixing flows," said Brian Dolan, chief currency strategist at Forex.com in Bedminster, New Jersey.
U.S. assets such as stocks had outperformed in April and investors looking to book profits and rebalance their portfolios had gone short the dollar in anticipation of selling dollars.
"But the market had got so short the dollar in anticipation of this, and a subsequent rally caught people wrong-sided," Dolan said.
U.S. DATA
The U.S. data was key to foreign exchange markets early in the New York session, analysts said.
Other government data showed the weak U.S. job market continued to pressure incomes and spending in March though investors saw more they liked than cause for concern.
"The longer we have stability -- no matter what level you have stability at -- if you have stability, that's the precursor to recovery," said Trevisani. "People had been trading on bad U.S. news and that had been pretty evident and you didn't get it today."
Christina Romer, chairwoman of the White House Council of Economic Advisers, said in testimony prepared for delivery to the Joint Economic Committee of the U.S. Congress on Thursday said that she saw glimmers of hope that the economy was stabilizing, but it was "hard to know" if a recovery would get underway later this year as expected or take longer.
