NEW YORK (AP) – Wall Street extended its losses Thursday, as a negative ratings outlook on financial and industrial powerhouse General Electric Co. shook an already fragile investor psyche and sent stocks tumbling.

After moving within a narrow trading range for much of the session, the Dow Jones industrial average dropped about 220 points. The broader Standard & Poor’s 500 index lost more than 2 percent.

Stocks struggled to find a direction in the early going Thursday as investors sifted through a number of economic indicators, including more layoffs and dismal earnings forecasts.

But a negative ratings outlook on GE from Standard & Poor’s added further pressure on the market.

The ratings service lowered its outlook on GE and its GE Capital finance arm to negative from stable. S&P affirmed their Triple-A ratings, but said there is a one-in-three chance they could lose them because of the ongoing financial struggles at GE Capital.

GE shares fell $1.43, or 8.2 percent, to close at $15.96.

At the same time, energy stocks tumbled as oil prices plunged.

Crude briefly dropped below $36 a barrel Thursday on worries of a drastic pullback in energy spending, even after a record production cut from OPEC earlier this week. The price settled at $36.22 a barrel in trading on the New York Mercantile Exchange.

Oil prices have been on a downward march since reaching a high of near $150 a barrel in July.

“The fear is that if oil does fall down to $25 or $30 a barrel, that could indicate that the economy is even weaker than market perception and that obviously is negative,” said Peter Cardillo, chief market economist for Avalon Partners.

Chevron Corp. fell $3.79, or 4.9 percent, to $73.03, while Exxon Mobil Corp. dropped $4.06, or 5 percent, to $77.

Thursday’s news reinforced the belief that the economy’s troubles are far from over. The market remains unsure how steep and prolonged the recession will be.

The expiration Friday of some options contracts for December added to the downward pressure, Cardillo said.

The Dow fell 219.35, or 2.49 percent, to 8,604.99. The Standard & Poor’s 500 index fell 19.14, or 2.12 percent, to 885.28, while the Nasdaq composite index fell 26.94, or 1.71, to 1,552.37.

The Russell 2000 index of smaller companies fell 7.42, or 1.52 percent, to 479.17.

Declining issues outnumbered advancers by about 3 to 2 on the New York Stock Exchange, where consolidated volume came to 5.46 billion shares, up from 5.18 billion shares on Wednesday.

Wall Street’s sharp decline late Thursday overshadowed some of investors’ earlier enthusiasm over a potential economic stimulus package. President-elect Barack Obama’s aides are working on assembling a two-year plan that could cost $850 billion and include new jobs, middle-class tax relief and expanded aid for the poor and the unemployed.

Further weighing on the market were lackluster economic data and mixed corporate earnings reports.

The Labor Department reported that initial jobless claims fell by more than economists anticipated to 554,000 last week. The claims remain near last week’s 26-year high, and the four-week moving average for claims is up, but investors had been bracing for a gloomier reading.

Meanwhile, a private research group’s measure of the economy’s health fell again in November and its six-month rate of decline hit the worst level since 1991.

“Most of the data was better than the market expected, but showed that the economy is still contracting,” Cardillo said.

FedEx Corp. reported a 3 percent rise in quarterly earnings, but announced further cost cuts as demand continues to wane. Ingersoll-Rand Co. cut its fourth quarter earnings forecast by more than half, and motor home maker Winnebago Industries Inc. swung to a loss.

But Discover Financial Services swung to a profit and homebuilder Lennar Corp.’s quarterly loss was smaller than last year’s.

In recent weeks, the market has moved away from the wild 300-point swings of September, October and early November, leading some analysts to believe that Wall Street is beginning to show some stability.

“People in general are less pessimistic,” said Bernie McGinn, chief executive of Alexandria, Va.-based McGinn Investment Management. “They are still not optimistic, but they are less pessimistic, and I think the market reflects that.”

Since the S&P 500 and the Dow hit multiyear lows on Nov. 20, the Dow is still up 13.9 percent, while the S&P 500 is up 17.7 percent.

But Thursday’s decline, which extended a 100-point drop in the Dow on Wednesday, showed just how fragile the market still is. Because stocks are up so much from their Nov. 20 lows, the market is more sensitive to news, said Chris Hensen, senior portfolio manager with MFC Global Investment Management in Toronto.

“News like this out of General Electric would make the market roll over,” he said.

The Dow fell on Wednesday as enthusiasm over the Federal Reserve’s historic rate cut the day before dampened on news of a larger-than-expected loss at Morgan Stanley and layoffs at Cooper Tire and Rubber Co. and Newell Rubbermaid Inc. The Dow and the S&P 500 are still down more than 30 percent for the year.

Also Thursday, Obama named three veteran regulators to round out his economic team and vowed to overhaul regulatory rules to prevent a repeat of the financial and economic turmoil the country is currently suffering.

Mary Schapiro, who currently heads a nongovernment regulatory group for securities firms, is Obama’s pick to lead the Securities and Exchange Commission.

The SEC faces mounting criticism for its failure to protect investors and detect trouble on Wall Street. Its latest blemish comes from the fraud investigation of prominent money manager Bernard L. Madoff, who is accused of running a $50 billion Ponzi scheme.

General Motors Corp. was the biggest loser Thursday among the 30 stocks that make up the Dow, plunging 16 percent, or 71 cents, to $3.66 as the Bush administration said it is seriously considering “orderly” bankruptcy as a way of dealing with the struggling U.S. auto industry. Ford Motor Co. shares fell 30 cents, or 9.6 percent, to $2.84. Chrysler LLC is not publicly traded.

Long-term Treasury prices soared, sending yields down to new record lows. The yield on the benchmark 10-year Treasury note fell to 2.07 percent late Thursday from 2.19 percent late Wednesday. The yield on the popular three-month T-bill – whose yield has at times gone negative due to frenzied buying – remained flat at zero.

The strong surge in buying has been stoked by the Fed’s decision Tuesday to lower its federal funds rate target to a range of zero to 0.25 percent, and express an interest in buying long-term government debt.

The dollar rose against the euro and the British pound, but fell against the Japanese yen. Gold prices declined.

The January contract for light, sweet crude, which closes on Friday, fell 9 percent, or $3.84, to settle at $36.22 a barrel on the New York Mercantile Exchange after dropping as low as $35.98, levels not seen since June 2004.

In Asia, Japan’s Nikkei stock average rose 0.64 percent, and Hong Kong’s Hang Seng index rose 0.24 percent. Britain’s FTSE 100 rose 0.15 percent, Germany’s DAX index rose 1.02 percent, and France’s CAC-40 fell 0.24 percent.
