However, the price of LME copper rebounded yesterday. However, it was blocked at 2840 US dollars and closed at 2805. US dollar / ton, compared with the previous day rose 22 US dollars / ton, fluctuations in the range of 2840 ~ 2773.5 US dollars / ton. Workers of the La Caridad copper mine smelter in Mexico went on strike yesterday. At the same time, Atlantic Metal Co. of Spain’s fourth quarter metal production was affected by the strike and reduced production, and a union spokesman said there will be at least 18 strikes in this month and next month. And the uncertainty of late strikes supported copper prices. However, from the graphical point of view, the current price of copper can only be determined as a relay drop in the decline, and the trend of copper prices in the later period is still not optimistic.

Aluminium: Due to the increase in copper prices, LME also saw a rebound in aluminum prices yesterday. China's Shanghai Aluminum yesterday showed a trend of bottoming out. From the disk, there is obviously a large support at the 16,000 yuan line. Since the price of 16,000 yuan is not far from the current production cost of aluminum, short-term copy of the chassis and short covering The role of the plate made Shanghai Aluminum fluctuate upward. The domestic spot price quoted yesterday was 16050 to 16100 yuan/ton. Ma Hongqing: Affected by the depreciation of the US dollar, LME copper prices maintained a volatile pattern on Tuesday, with the price rising from the Far East's decline, but the pressure level on the 2850 line is still strong. The spot premium is still maintained at a level of around US$80. It has not been further amplified with the rise in copper prices, indicating that spot prices are under pressure from above 2900. The kinetic indicators show that the copper price is unlikely to increase further, and indicators reflecting its future trend indicate that the copper price will fall into a short-term market, with the fluctuation range at 2780/2850 or further amplification to 2750/2870.

In order to maintain the current prosperity of the economy means that inflation must be controlled, this is clearly a potential negative for commodity prices at historically high levels. Given that the spot market of the copper market is still tight, the possibility of a recurring fall in copper prices in the short term is unlikely, and the probability of maintaining a gradual decline in the market is relatively large.
