COPPER SHINES; Copper prices rose 2.2 percent after China's central bank reported an unexpected increase in loans last month. That's creating more hope that demand may improve for the industrial metal. China is a huge importer of copper and other raw materials.
TRADE BOOST: Commodities also benefited from a report that the U.S. trade deficit shrank in February to $46 billion and exports rose to an all-time high.
WINNERS, LOSERS: Prices for gold, silver, oil, wheat, corn and soybeans rose. Natural gas fell slightly.
