SHANGHAI, Sept. 20 (SMM) -- LME base metals prices closed with gains last Friday, and LME aluminum prices showed signs of rising further this morning. SHFE aluminum prices opened slightly higher today positively affected by rising LME aluminum prices and China's central bank's remarks that China will continue the moderately loose monetary policy, with SHFE 1012 aluminum contract prices testing RMB 15,700/mt. If the Shanghai Stock Exchange composite index shows positive performance today, SHFE 1012 aluminum contract prices will move higher gradually, with prices expected to move between RMB 15,650-15,800/mt today.
