NEW YORK, May 8 (Reuters) - Oil prices retreated after almost setting a new high on Thursday and U.S. stocks rose slightly, lifted by encouraging economic data and energy shares that rose with crude trading at more than $120 a barrel.
The dollar fell as the euro rebounded from a two-month low against the greenback after the European Central Bank left interest rates in the euro zone unchanged and the bank focused more on inflation than some had expected.
U.S. shares climbed after data showed the number of U.S. workers filing claims for initial jobless benefits fell last week and retail sales rebounded in April, suggesting that the economy, while soft, was not crumbling rapidly.
"What we've seen in all the economic data is a really harsh economic slowdown but not a recession," said Marc Pado, U.S. market strategist with the San Francisco office of Cantor Fitzgerald & Co.
"We're still bumping along a bottom, not recovering yet, but certainly not in deep negative territory like a lot of people would have us believe," Pado said.
Many economists have concluded the U.S. economy is in recession, but a string of recent data supports analysts who argue the United States may be able to dodge a downturn.
Initial claims for state unemployment benefits fell to 365,000 from 383,000 the prior week, the Labor Department said. The level was slightly lower than Wall Street had expected.
Separately, 68 percent of U.S. retailers reported better-than-expected sales at stores open at least a year, partly reflecting strong results at discount chains as consumers tried to hold down their food expenses.

The Nasdaq Composite Index < > rose 10.86 points, or 0.45 percent, to 2,449.35.Shares in Europe fell slightly as both the ECB and the Bank of England kept rates the same and investors saw little to suggest euro zone borrowing costs would fall soon.

The Bank of England kept rates at 5 percent and the ECB stayed at 4 percent. ECB President Jean-Claude Trichet said his bank's policy stance would help it achieve price stability, although inflation was likely to remain high for some time amid turbulent markets.
"The ECB will need to see more of a slowdown in the economy for the next months before it lowers rates, and we expect this to happen in the beginning of fall or end of summer," said Thierry Lacraz, strategist at Swiss bank Pictet.
