Chinese A-shares opened lower collectively on March 27th. As of 9:55 AM, all four major indices had fallen by more than 1%, with over 4,500 stocks declining across the market.
In early trading, the non-ferrous metals/aluminum sector opened higher as a group. Tianshan Aluminum Group, Minfa Aluminum, and Changzhou Aluminum opened limit-up. Ye Chiu Metal, Shenhuo Group, Yunnan Aluminum, Aluminum Corporation of China, and Weiqiao Pioneering were among the top gainers. Reports indicate that two major aluminum plants in Bahrain and the United Arab Emirates were recently confirmed to have been attacked by Iran. Aluminum products exported from the Middle East account for approximately 10% of global supply, which could impact the market. Stimulated by this news, LME aluminum prices rose 5% following the attacks.
