After the recent close of speculative selling, the price of the base metal was still consolidated in a narrow range. However, the market is still worried about fund selling and year-end factors. The dollar is still the key factor, and as short positions are closed, it may continue the recent rebound, which will strengthen the trend of weak base metals. The correction of the base metal is regarded as a result of long-term profit-taking, and this profit-taking is basically not driven by a significant change in fundamentals. Demand has weakened due to seasonal factors, but spot premiums remain strong. Copper: LME stocks continue to decline, and before the next week expires in December, the market still has some concerns about recent interest in borrowing transactions, which may prompt more radical short sellers to temporarily stop short selling. The price went low and tested support around 2850. However, the support has been steady and prices have rebounded. However, the market is still nervous about further fund selling, and the rebound has not reached the resistance level of 2900. Technically, the price closes above 100MA (2874), but it will take time to confirm whether the decline will be postponed. The resistance is at 2920, only the price regains this price, and the tentative bottom can be formed. Aluminium: The price has remained reasonably stable, and the weak chart trend has caused aluminum prices to bear the downward pressure of long liquidation. Although LME stocks have been falling again, stocks are likely to increase further given the weak demand and the market’s expectation that China’s export tax rebates will be cancelled. Technically, the 1780's support remained strong, but the price lacked the 1800 test.
