On June 10, Chalco (02600.HK) fell 3.64% in regular trading, trading at HK$9.83/share, with trading volume of HK$23.55 million.

On the news front, the stock continues to exhibit a classic buy-expectation-sell-fact pattern following its formal inclusion in the Hang Seng Index constituent stocks on June 8, when it plunged 8%. The stock had previously surged on dual catalysts — Guinea's planned aluminum ore export controls in June and the HSI inclusion announcement — hitting the daily limit on May 26. Since then, major institutional and northbound funds have been consistently selling, with significant net outflows over multiple consecutive trading days. The company had also previously cut aluminum ingot spot prices across regions.

The broader aluminum sector remains under pressure, with peers China Hongqiao down 3.36%, Chuangxin Industrial down 3.65%, Nanshan Aluminum International down 2.17%, and Rusal down 0.29%. Meanwhile, global asset manager BlackRock disclosed an increase in its Chalco H-share stake from 8.69% to 9.40% as of June 2, suggesting some institutional divergence in outlook.
