On August 12, CHALCO rose 3.57% in regular trading, trading at HKD 8.885/share, with turnover of HKD 35.37 million. The move was driven by the company's announcement that its controlling shareholder Chinalco Group and its concert parties have cumulatively increased their holdings by approximately 77.36 million shares, representing 0.45% of total issued share capital, with a cumulative investment of approximately RMB 659 million.

The incremental purchases span both A-shares (47.60 million shares) and H-shares (29.76 million shares), executed between July 20 and August 11. Chinalco Group had previously secured a special-purpose loan commitment of up to RMB 1.8 billion from ICBC Beijing Branch dedicated to share purchases, with the total plan sized at RMB 1.0–2.0 billion, leaving substantial room for further accumulation. Additionally, JPMorgan Chase raised its long position in CHALCO H-shares to 6.11% from 5.83%, signaling synchronized institutional accumulation.

Within the Aluminum sector, CHINAHONGQIAO rose 1.66%, CHUANGXIN IND rose 1.95%, NANSHAN AL INTL rose 1.34%, RUSAL rose 0.32%, and XINGFA ALUM was flat.
