Copper prices inched higher to get back to positive territory for the year and close at a more-than-four-year high on Friday, as traders digested strong China import figures and copper’s momentum continued. Front-month copper for June delivery rose 0.8% to $3.2930 a pound on the Comex division of the New York Mercantile Exchange, its highest close since February 2014, following a sixth-straight session of gains. Most-actively traded futures also closed near a more-than-four-year high.
