Copper and aluminum: Yesterday, Shanghai copper trading was surging. Last night, LME copper showed calm. In addition to the electronic trading with Shanghai copper fell from 2970 to 2740, the transaction was "thunder and rain," a small amount. The low of 2927 and the closing of 2958 - it is a superficial position. The performance of Shanghai Copper yesterday showed that after warning signals were issued on the LME weekly Yin line last week, the original ambiguous bears joined the ranks of short selling, and short-term bullish people also “smeared their feet†and saw the rudder. However, no matter whether it was LME copper or Shanghai copper yesterday, there was no further favorable conversion to bears. The author proposes two reference points: (1) If the signal of the transition is clear, the market will not stay above it until today when there is an immeasurable drop in Shanghai copper; (2) If it is weak, the price will be yesterday. Hit the trading price below the daily limit on January 5, and yesterday's domestic trading situation is just the opposite. Of course, we do not consider doing more for the time being. Shanghai Aluminum's trading volume shrank sharply yesterday. Its volatile trading characteristics will remain for a period of time. It may decline slightly in the near future and the transaction will mainly be wait-and-see. Date: 2005-1-11
