ECONOMIC CONCERNS: Commodity prices were mostly lower as investors searched for clues about where the economy is headed and the potential impact it may have on demand.
OIL'S IMPACT: Much of the focus is on oil after the International Energy Agency said it plans to release 60 million barrels of crude from emergency stocks in an effort to take the pressure off global oil prices. Oil prices rose slightly Friday after plunging 4.6 percent the day before.
MIXED BAG: Gold, silver, platinum and palladium fell while copper rose. Prices for corn, wheat and soybeans settled lower.
