NEW YORK -- Copper prices hit a one-year high last week and could continue to climb as speculators flood the market, experts say.

Copper prices rose $1,000 to over $6,000 a ton at one point, and peaked at $2.73 a pound, roughly 30% above its price two months ago.

Pricing rose daily for two straight weeks, the longest streak in nearly 30 years.

Analysts say an improved forecast for China plus anticipated new spending on US infrastructure projects are behind the surge. However, one analyst says production of copper next year will outpace demand by 420,000 tons, indicating that pricing is ahead of reality.
