On that day, domestic copper prices and aluminum prices both fell. However, judging from the ratio of copper prices, the copper market still has the characteristics of resilience. The decline in recent months is less than that in the long run, and the spot premium has been pulled away again, which means that the copper market has not turned around and the shock is still the main tone of the metal copper market. In the aluminum market, today's Shanghai futures aluminum price decline almost swallowed up the gains in the previous three trading days, once again verifying the changeable characteristics of the aluminum market. However, due to the fact that the aluminum price has fallen less than the forward price in recent months, the aluminum market will not have much room to fall, and the adjustment of the aluminum market is expected to continue to provide new buying opportunities, paying special attention to the investment opportunities of forward contracts. Of course, the recent weakening of crude oil and precious metals prices will have a certain impact on the basic metal market, but the impact should be limited. LME market operation suggestion, hold aluminum long position appropriately.
