NEW YORK (MarketWatch) -- U.S. stocks on Wednesday extended losses into a third day after an upbeat report on the manufacturing sector failed to offset worries about declining commodities prices and the collapse of a hedge fund partly owned by Lehman Brothers.
"There is a tremendous amount of uncertainty out there, and that uncertainty is breeding volatility. There is weak demand for energy and commodities across the board, and everybody is trying to get out at the same time, and that is hurting equities," said Anthony Conroy, managing director and head trader for BNY ConvergEx Group.
The Dow Jones Industrial Average declined 58.37 points to 11,458.55, with 18 of its 30 components posting losses, which were more recently led by Intel Corp. down 4.2%.
Home Depot Inc. fronted gains on the blue-chip index, up 3.1%.
"The market is going down because of the perception that the commodities markets are falling apart, which is being perceived as due to weaker economic activity on a global scale, putting pressure on the equities markets," said Peter Cardillo, chief market economist at Avalon Partners.

Energy and information technology led sector losses on the S&P, while financials and telecommunication services led sector gains among the S&P's 10 industry groups.

The major indexes had wavered between positive and negative territory after the Commerce Department reported factory orders rose by 1.3% in July, better than the 0.8% forecast by economists.
"One bright spot is factory orders were better than expected, and capital spending was way up for a second month in a row, showing that while the consumer has pulled back, businesses have not, at least over the last several months," said Cardillo.
Lehman holds a 20% stake in Ospraie Management LP, which said on Tuesday it's closing its flagship commodity hedge fund. At last check, shares of Lehman were up 15 cents at $16.28.
"Another negative is the fund closure. Once you have liquidating in certain commodities, it spreads, so what we have here is a market faced with traditional weakness in the month of September, and complicating that weakness is the decline of commodity prices, which is being perceived as weakness in the global economy," said Cardillo.
