Copper fell on Thursday on profit-taking after hitting record highs earlier in the week, but losses were limited by US data pointing to a better economy in 2011 and possibly tighter supplies ahead. In New York, copper's March contract lost 0.4 percent, finishing at $4.2585 a lb.

"It keeps up hopes, with the added liquidity from the government in 2011, it points to a solid market next year," said Cort Gwon, director of trading strategies and research at FBN Securities in New York.
