Peru influence compelling traders to rethink copper

News out of Peru gave traders a reason to pause and rethink on Monday and Tuesday as reports say leftist political candidate Ollanta Humala has taken the lead in the latest polling.

Along with Peruvian stocks copper, gold and silver all turned south on Monday and were having trouble maintaining an upside bias on Tuesday. Peru is the second-leading copper producer, the largest silver producer and the fifth-largest gold producer.
