NEW YORK, Oct 23 (Reuters) - Oil prices rose on Thursday ahead of an OPEC meeting while U.S. stocks failed to hold a brief rally after a dismal holiday sales outlook from Amazon and rising jobless claims pointed to a darkening economy.
A thick cloud of risk aversion hanging over financial markets had scattered earlier with investors diving into beaten-down energy shares, lifting U.S. equity markets and turning currency and government debt markets around.
The U.S. stock bounce helped pulled European shares off 3.2 percent lows to close slightly lower but the gains soon lost steam, pulled down by the bleak economic outlook.
"The market overall remains very radically oversold but it has been for weeks now," said Chip Hanlon, president of Delta Global Advisors Inc in Huntington Beach, California.
"One would think one of these rallies would take hold and move substantially higher, but after a few false starts it becomes harder to have conviction that this is the one."
U.S. workers lined up for jobless benefits in unexpectedly large numbers last week as the trauma in financial markets continued to hammer the economy, fresh U.S. government data showed.
Adding to the gloom companies announced deeper job cuts to stop the financial bleeding caused by the credit crisis.
Amazon.com Inc <AMZN.O> said end-of-year holiday sales would fall short of Wall Street's expectations, driving its shares 6.7 percent lower and pulling down the Nasdaq.
"We're looking at the economy contracting in the fourth quarter very sharply, certainly contracting in the first quarter, maybe contracting in the second quarter as well," said Nigel Gault, chief U.S. economist at Global Insight in Lexington, Massachusetts.
"Going through that whole period with GDP actually declining, all the time that's happening, you're going to see heavy job losses," Gault said.
After 1 p.m., the Dow Jones industrial average <
> was down 80.76 points, or 0.95 percent, at 8,438.45. The Standard & Poor's 500 Index <.SPX> was down 15.10 points, or 1.68 percent, at 881.68. The Nasdaq Composite Index < > was down 45.68 points, or 2.83 percent, at 1,570.07.Declining shares outnumbered advancing shares by almost 3 to 1 on the New York Stock Exchange, and almost by 4 to 1 on Nasdaq.
Energy shares led an upward charge on both sides of the Atlantic, lifted by rising oil prices a day before an emergency meeting of the Organization of Petroleum Exporting Countries. Many OPEC members have called for supply cuts.
Oil giants were the major gainers in Europe, with BP <BP.L> and Royal Dutch Shell <RDSb.L> both rising more than 5 percent. In the United States, Exxon Mobil <XOM.N> and Chevron <CVX.N> rose 6.7 percent and 7.3 percent, respectively.
Although not as violent as other recent sessions, U.S. indexes swung between positive and negative territory a day after stocks closed at five-year lows.
The FTSEurofirst 300 <
> index of top European shares ended 0.1 percent lower at 872.72 points as losses in banks and automobiles eclipsed the gains in oil and defensive shares.Mercedes-Benz maker Daimler <DAIGn.DE> fell 1.3 percent as it lowered its full-year revenue and profit forecast after third-quarter operating profit plunged by two-thirds.
"The market did not like Daimler results," said Philip Lawlor, a strategist at Nomura.
"Daimler is very exposed to the high-end market which is falling off a cliff in the U.S. It is a reiteration of just how grim the economic backdrop is a the moment," he said.
Oil rose more than $2 a barrel. The bounce in crude prices may have gained some momentum on buying to cover positions that had bet oil prices would continue their slide, traders said.
"We may well be experiencing some short covering in front of tomorrow's meeting in Vienna," said Robert Laughlin of MF Global in London.
U.S. light sweet crude oil <CLc1> rose $1.13 to $67.88 a barrel.
Spot gold prices <XAU=> fell $11.25 to $716.40 an ounce.
The euro rebounded versus the dollar after the U.S. currency touched a two-year high as gains in the stock market prompted some profit-taking against the greenback.
But the euro later fell against the dollar and analysts said currencies remained vulnerable to erratic moves.
"Investors are still very panicky and very much in a trigger-happy mood. The market is still dominated by risk aversion flows and and we are pretty much trading off what equities are doing," said Boris Schlossberg, director of foreign exchange research at GFT Forex in New York.
"The reason we have such volatility is because visibility is completely clouded. Almost all asset classes are being priced for a very serious, almost depression-like scenario and the market is waiting to see if this is going to happen."
The dollar rose against a basket of major currencies, with the U.S. Dollar Index <.DXY> up 0.21 percent at 85.617. Against the yen, the dollar <JPY=> fell 0.77 percent at 97.11.
The euro <EUR=> fell 0.26 percent at $1.2819.
U.S. government debt prices also rode up and down, while euro zone government bond futures erased gains in late trade when U.S. stocks briefly recovered.
The benchmark 10-year U.S. Treasury note <US10YT=RR> rose 11/32 in price to yield 3.56 percent, while the 2-year U.S. Treasury note <US2YT=RR> slipped 2/32 in price to yield at 1.53 percent.
