Copper stocks surged as reports suggest Trump's proposed 50% tariffs may cover refined copper. The U.S. imports half its copper, mainly from Chile, with only three domestic smelters. Industry players oppose the move, urging scrap export restrictions instead. Retail sentiment on Freeport-McMoRan (FCX) is highly bullish. Copper prices rose 0.14% on the LME; FCX is up 21.2% YTD.
