On May 28, Chalco (02600.HK) fell 3.14% in regular trading, trading at HK$11.14/share, with trading volume of HK$133 million.

The decline marks a second consecutive session of pullback following the stock's sharp rally on May 26, when its A-share hit the daily limit-up of 10.01% and its Hong Kong-listed shares surged over 6%. That rally was driven by dual catalysts: Guinea — the world's largest bauxite producer accounting for over one-third of global output — announced plans to implement bauxite export controls in June, and Chalco was confirmed for inclusion in the Hang Seng Index effective June 8.

After the sharp gains, short-term profit-taking has intensified over two sessions. The broader aluminum sector remains under pressure, with China Hongqiao down 2.17%, Chuangxin Industrial down 4.22%, and Nanshan Aluminium International down 1.44% on the same day, reflecting continued cooling in sector sentiment.
