NEW YORK, Nov 10 (Reuters) - U.S. stocks fell on Monday, as investors worried about the outlook for companies, including General Motors<GM.N> and Goldman Sachs <GS.N>, given the global economic downturn and enthusiasm for China's deep-pocketed stimulus plan faded.
The financial sector led the way lower after Barclays analysts said they expected Goldman Sachs to post a quarterly loss for the first time in the company's history due to steep equity market declines.
In another piece of worrisome news for the beleaguered sector, the cost of rescuing American International Group Inc <AIG.N> jumped to $150 billion after a smaller bailout failed to stabilize the ailing insurance giant,
Dow component GM's shares, meanwhile, fell to 62-year lows after Deutsche Bank recommended that clients sell the automaker's shares and a number of brokerages warned that GM and its rivals are burning through cash fast.
McDonald's Corp <MCD.N> helped the Dow fare better than the S&P 500 and Nasdaq. The world's largest hamburger chain said global sales at its fast-food restaurants open at least 13 months rose 8.2 percent in October, topping analysts' targets.
Stocks worldwide initially rose after China approved a $586 billion government spending package and said it would adopt a "moderately easy" monetary policy. But the euphoria swiftly fizzled as investors doubted that the steps would work quickly enough to lessen the blow of a steep global economic downturn.
"Talk Goldman Sachs will report a loss for the quarter is contributing to this sell-off. It seems to be overwhelming the longer-term positive associated with the Chinese stimulus," said Phil Orlando, chief equity market strategist at Federated Investors in New York.
"China's stimulus won't work instantaneously and we're already in a global recession," Orlando said.
The Dow Jones industrial average <
> slipped 59.89 points, or 0.67 percent, to 8,883.92. The Standard & Poor's 500 Index <.SPX> dipped 10.93 points, or 1.17 percent, to 920.06. The Nasdaq Composite Index <.IXIC was down 25.72 points, or 1.56 percent, at 1,621.68.Google <GOOG.O> shares weighed on the Nasdaq after Barclays Capital cut its fourth-quarter revenue estimates on the Web search leader and lowered its price target on the stock, citing further macro weakness. Google shares fell 5.9 percent to $311.71.
Goldman Sachs shares lost 10.4 percent to $69.68 after Barclays analysts said they expected Goldman to post a fourth-quarter loss of $2.50 per share.
GM's stock plummeted 21.6 percent to $3.42, dragging along rival Ford <F.N>, whose shares declined 4.5 percent to $1.93. On Friday, both companies posted wider-than-expected quarterly losses.
McDonald's shares rose 2.5 percent to $56.85.
Adding to the market's jitters, major electronic retailer Circuit City <CC.N> was forced into bankruptcy just weeks before the holiday shopping season.
China's economic stimulus involves new government spending between now and 2010 and would focus largely on infrastructure and social projects. For details, see [
