Amalgamated Metal Trading Limited (AMT), a leading brokerage of the London Metal Exchange (LME), issued a daily commentary on the base metals of LME on the 19th. Copper: The selling pressure is heavy at $3050, and it is expected to maintain the oscillation trend in the short-term. Aluminium: There is a strong resistance at $1,860. It is expected that the short-term trend will be dominated by oscillations. Lead: All-day trading is light, short-term supply concerns have been basically eliminated, the future trend is not clear, and wait and see. Zinc: Driven by technical buying and setting a new high in seven years, attention should be paid to short-term risks. Tin: It was boosted by the shortage of market supply, but the short-term trend was uncertain and we kept watching. Nickel: Close to 14,500 US dollars against the market outlook.
