COPPER HOPES: Copper prices rose after a report on U.S. home sales suggested the market is slowly getting better. Sales of previously occupied homes have benefited from a mild winter and an improving job market.
WAITING ON THE ECONOMY: Gold prices were up slightly as investors wait to see how global economic growth is faring. Gold often is used as a hedge against inflation. The price is up about 5 percent this year.
PRICE MIX: Oil, silver, natural gas and soybean prices finished higher. Platinum, palladium, wheat and corn fell.
