US copper futures rose to a one-week high Monday on the back of a weak dollar and demand optimism stemming from stronger imports of the metal into China, the world's largest consumer of the metal. But the bullish momentum faded and traders booked profits after overnight inventory data showed another large build in London warehouse stockpiles.
Copper for March delivery ended up 1.90 cents at $1.3455 a lb on the New York Mercantile Exchange's COMEX division.
