Stocks on Wall Street ended a choppy trading session Wednesday with losses as investors were dealt another round of earnings reports and weighed a cut in oil production from OPEC.

The

Dow Jones Industrial Average

ended down 99.8 points, or 1.1%, at 8824.34, and the

S&P 500

lost 8.76 points, or 1%, to 904.42. The

Nasdaq

finished down 10.58 points, or 0.7%, at 1579.31.

Oil-exporting cartel

OPEC

said Wednesday it will cut its production target by another 2.2 million barrels a day starting in January.

The cut, which could help stabilize oil prices that have fallen with global economic hardships, was slightly more than expected. But crude oil settled $3.54 lower at $40.06 a barrel.

"Right now the market doesn't care about the supply part of the equation," says Darin Newsom, DTN Senior Analyst. "It's dealing with lack of demand from consumers -- and investors - at this point," he says.

Meanwhile, the fallout from the

Bernard Madoff

scandal continued to play out. Late Tuesday,

Securities and Exchange Commission

Chairman Christopher Cox demanded an internal investigation of why regulators from his agency failed for a decade to investigate the Wall Street money manager, who last week was charged with running an elaborate and far-reaching Ponzi scheme that lost an estimated $50 billion for investors. A formal investigation of complaints would have forced Madoff to provide documentation years ago.

On Tuesday, the Fed cut its federal funds rate target to a range of 0% to 0.25%, a steep cut that surprised Wall Street and set a historic low for the key rate.

On Wednesday, the 10-year Treasury was up 27.5/32 to yield 2.2%, while the 30-year note was up 2 15.5/32 to yield 2.6%. The

dollar

was mixed against other major currencies. Gold was rising 60 cents to $869.10 an ounce.

In Asia, Japan's Nikkei and Hong Kong's Hang Seng ended higher. In Europe, Germany's DAX and France's CAC-40 edged lower.
