SHANGHAI, Nov. 19 (SMM) – January aluminum on the SHFE, the most active one, opened at RMB 14,260/mt on Tuesday. Falling base metals prices ignited bearish sentiment, pulling SHFE 1401 aluminum contract down below the 10-day moving average in the morning session and down further below RMB 14,200/mt in the afternoon. Finally, the light metal finished 0.25% lower at RMB 14,185/mt. Trading volumes dropped 574 lots to 4,904 lots, but positions added 380 lots to 45,070 lots.
