On June 12, Chalco (02600.HK) rose 4.16% at open, trading at HK$10.26, with turnover of HK$2.3188 million.

On the news front, the stock appears to be staging a technical rebound following a prolonged sell-off that saw it decline from its May 26 daily limit-up level through multiple consecutive sessions of losses. The stock fell approximately 8% on June 8 when its formal inclusion in the Hang Seng Index took effect, and continued sliding to HK$9.67 by June 11, exhibiting a classic buy-the-expectation-sell-the-fact pattern.

Supporting the rebound, Hong Kong Exchange filings revealed that BlackRock increased its stake in Chalco H-shares to 10.44% as of June 4, crossing the significant 10% threshold from a prior 9.66%. This marks the second notable accumulation by the global asset manager within days, signaling institutional confidence in the company's fundamentals.

Within the Aluminum sector, peers also showed mild recovery, with China Hongqiao up 2.24% and Nanshan Aluminium International up 1.17%.
