Copper Rises for Third Straight Day as U.S. Economy Accelerates

Copper rose for the third straight day after a report showed that the economy accelerated in the U.S., the world’s second-biggest consumer of the metal.

Gross domestic product grew at an annual rate of 3.2 percent in the fourth quarter following a 2.6 percent increase in the previous quarter, Commerce Department figures show. In 2010, the economy expanded 2.9 percent, the most in five years. Copper also gained as inventories tracked by the Shanghai Futures Exchange dropped for the second consecutive week.
