On August 28, CHALCO rose 3.55% in regular trading, trading at HKD 8.835/share, with turnover of HKD 75.58 million.

The rally was driven by the company's interim results disclosed on August 27. CHALCO reported H1 revenue of RMB 125.413 billion, up 7.74% year-over-year, with net profit attributable to shareholders reaching RMB 11.871 billion, a 67.91% surge. Operating cash flow climbed 84.91% to RMB 26.235 billion. Notably, operating costs declined by RMB 5.329 billion to RMB 92.859 billion, signaling significant cost-side improvement. The company also proposed an interim dividend of RMB 0.276 per share, further boosting market sentiment.

The strong earnings were underpinned by favorable aluminum price dynamics, with supply disruptions including the Alunorte alumina plant in Brazil cutting output to 50% capacity due to a natural gas interruption, reinforcing the medium-term narrative of rising aluminum price floors. Additionally, controlling shareholder Chinalco had previously accumulated approximately RMB 659 million in share purchases, reflecting confidence in the company's valuation.
