COPPER PRESSED: Copper prices fell ahead of reports expected this weekend that could shed more light on China's economic slowdown. The price dropped 8.55 cents to finish at $3.285 per pound, the lowest since mid-December.
EYES ON CHINA: China is scheduled to release May trade and industrial data. Some analysts speculated that the details may show China's economy is weaker than previously expected. China is a huge importer of copper and other commodities, so slower economic growth there affects demand for those materials.
MIXED BAG: Prices rose for gold, corn and natural gas. Industrial metals, oil, wheat and soybeans fell.
