Steel and aluminum prices were taking a hit Tuesday, June 19, amid escalating trade war rhetoric between U.S. and China. 

After President Trump's announcement late Monday on possible more tariffs on China, steel and aluminum stocks plummeted. The possibility of a trade war with China has investors feeling gun-shy about the future profit potential of heavy machine industries

United States Steel Corp. (X) and Steel Dynamics Inc. (STLD)  each slipped more than 3% on Tuesday, June 19. 

AK Steel Holding Corp. (AKS) and Nucor Corp. (NUE)  each fell 2%.

Aluminum stocks were taking more of a hit than those in the steel industry. Century Aluminum Co. (CENX) shares dove more than 6.4%. Kaiser Aluminum Corp. (KALU) dropped 2%, and Reliance Steel & Aluminum Co. (RS) was down 2.5%.
