期铜及其他基本金属大跌，受获利了结打压【1月30日LME收盘】

Core Viewpoint - The decline in copper prices on January 30 is attributed to a stronger US dollar and profit-taking by investors after reaching a historical high the previous day. Group 1: Market Performance - On January 30, LME three-month copper fell by $461, or 3.39%, closing at $13,157.00 per ton, while remaining above the 21-day moving average support level of $13,011 [1] - The cumulative increase in copper prices for the month is 6%, with speculative buying pushing prices to a historical high of $14,527.50 [3] - Other base metals also experienced declines, with three-month aluminum down $74.5 (2.31%) to $3,144.00, three-month zinc down $10 (0.29%) to $3,402.00, and three-month lead down $5 (0.25%) to $2,009.00 [2][4] Group 2: Market Dynamics - Profit-taking and a stronger dollar have jointly pressured prices downward, with analysts indicating that the record performance of copper prices cannot be explained by market fundamentals [3] - The copper premium at Yangshan port in China rose by 17% to $27 per ton, reflecting low historical levels of copper import demand despite the price drop [3] - The strengthening dollar has made metals priced in dollars more expensive for buyers using other currencies, exacerbating the sell-off in base metals [3]
