Shanghai copper trimmed early losses and London copper rebounded on Wednesday, supported by strong equities, while demand worries continued to linger amid Japan's nuclear crisis and China's attempts to curb inflation. Large copper stockpiles in top consumer China were also weighing on market sentiment.
Shanghai's most-active copper futures contract declined more than 1 percent earlier in the day, but pared losses to close at 72,180 yuan ($11,036), down 0.2 percent. Shanghai lead fell to a two-week low of 18,540 yuan, before recovering to close at 18,715 yuan.
