(Adds close of U.S. markets)

NEW YORK, May 1 (Reuters) - U.S. stocks rallied on Thursday as a surging dollar and falling commodity prices eased inflation fears and revived investors' appetite for risk, especially for beaten-down financial and technology shares.
Oil prices fell as concerns about Nigerian crude supplies eased following a strike deal and U.S. demand showed further signs of weakness. Gold hit a four-month low below $850, triggering a sell-off in other precious metals.
Treasury debt prices retreated as U.S. economic data suggested the Federal Reserve would put its monetary easing on hold, lifting the dollar against the euro and to a seven-week high against a basket of major trading-partner currencies.
Investors took heart in the positive aspects of U.S. spending and core inflation data, as well as a manufacturing survey for April.
They also shrugged off higher-than-expected U.S. initial jobless claims a day before the government's April jobs report and after the Federal Reserve cut a benchmark interest rate to 2 percent to stimulate the flagging economy.
Shares of Apple Inc <AAPL.O> jumped 3.5 percent on news of a deal to sell movies on iTunes the same day they are available on DVD, boosting the outlook for iPod media player sales.
Research In Motion Ltd <RIM.TO><RIMM.O>, the BlackBerry maker, jumped 5.3 percent and also helped to drive the Nasdaq near its highest level this year.
"Never have I seen tech this cheap," said David Bianco, chief U.S. equity strategist at UBS in New York. "So when you've got some signs of encouragement in the economy, I think people are feeling as if they can take advantage of the value seen in tech."
As tech shares gained, energy companies' stocks fell, a trend aided by disappointing quarterly results from oil company Exxon Mobil Corp <XOM.N>, whose shares fell 3.6 percent.
The S&P Financial index <.GSPF> surged almost 4 percent, led by a 5 percent gain in Bank of America <BAC.N> and Citigroup's <C.N> 4.3 percent rise.
The Dow Jones industrial average <
> rose 189.87 points, or 1.48 percent, to 13,010.00. The Standard & Poor's 500 Index <.SPX> gained 23.75 points, or 1.71 percent, to 1,409.34. The Nasdaq Composite Index < > added 67.91 points, or 2.81 percent, to end at 2,480.71.European shares ended flat as vague merger and acquisition chatter supported miners, while consolidation hopes helped propel British Airways <BAY.L> 7.3 percent higher.
The pan-European FTSEurofirst 300 index <
> ended up 0.1 percent at 1,339.02, with British shares unchanged at 6,087.3.Investors shrugged off data showing that growth in Britain's manufacturing sector slowed in April, as expected. But there was no let-up in inflationary pressures as firms ratcheted up prices at the fastest rate on record.
Investors also were optimistic after the Bank of England said the scale of losses and the economic fallout from the global credit crunch may not be as bad as feared and subprime losses could end up costing less than half market forecasts.
The dollar rose after the Fed on Wednesday indicated it was worried about rising inflation expectations, suggesting it would pause in cutting rates.
"The most important thing right now is the U.S. dollar," said Tim Smalls, head of U.S. stock trading at brokerage firm Execution LLC in Greenwich in Connecticut.
"As long as the dollar continues to rally as it's doing right now, commodities are going to come off and the inflation scare gets mitigated slightly."
The dollar rose against major trading-partner currencies, with the U.S. Dollar Index <.DXY> up 0.93 percent at 73.282.
The euro <EUR=> fell 1.04 percent at $1.5453, and against the yen, the dollar <JPY=> rose 0.41 percent at 104.35.
Bond prices succumbed to traders paring bond positions ahead of Friday's U.S. payroll report, investors said.
"The bond market is suggesting that the rate-cutting cycle is in a pause or near the end," said Colin Lundgren, head of institutional fixed-income at RiverSource Investments in Minneapolis.
The benchmark 10-year U.S. Treasury note <US10YT=RR> fell 10/32 to yield 3.77 percent. The 2-year U.S. Treasury note <US2YT=RR> fell 7/32 to yield 2.38 percent. The 30-year U.S. Treasury bond <US30YT=RR> fell 14/32 to yield 4.50 percent.

Oil has fallen from record highs near $120 hit last month as demand in the United States, the world's top consumer, sags under the weight of surging fuel prices and wider economic problems.
U.S. oil demand fell 7 percent in February compared with year-ago levels, according to a report from the U.S. Energy Information Administration released this week.
