NEW YORK ( TheStreet) -- Southern Copper ( SCCO), Freeport-McMoRan Copper & Gold ( FCX), Teck Resources ( TCK), Vale ( VALE) and Rio Tinto ( RIO) are five copper stocks with potential upside of 17%-39% based on consensus analyst estimates for the upcoming 12 months.

A Standard Bank analyst comments that on a seasonally adjusted basis, April is a strong month for copper demand. China accounts for nearly 39% of global copper demand and the same is expected to expand by 9.5% in 2011, outpacing Europe by more than five times, as per median estimates of a Bloomberg survey of 19 economists. As Japan moves toward its restructuring program, demand for copper is set to boost.

A Goldman Sachs analyst believes that despite copper prices stalling in the next few months, prices will rebound and rally to $11,000 in 12 months on tightening supply and bullish demand -- an 18% increase from the current level.

A senior director at Fitch expects copper to remain in deficit in the current and the upcoming year with LME copper inventories hitting one- to two-week supply levels. Market analysts expect copper supply deficit of 444,000 tons in 2011, and a narrower 184,500 tons deficit in 2012, but prices are expected to remain high.
