On August 26, CHALCO rose 3.12% in regular trading, trading at HKD 8.705/share, with turnover of HKD 31.88 million.

On the news front, the company's board is scheduled to convene on August 27 to review unaudited interim results for the six months ended June 30 and to consider an interim dividend proposal, prompting early positioning by investors. Meanwhile, the aluminum sector rallied broadly, with China Hongqiao up 2.47% and RUSAL up 2.68%.

On the supply side, Norway's Hydro previously announced that its Alunorte alumina plant in Brazil — the largest outside China with 6.3 million tonnes annual capacity — has cut output to 50% due to natural gas supply disruption. Analysts estimate this could reduce overseas monthly alumina supply by 160,000-260,000 tonnes, reinforcing the medium-term narrative of aluminum price upside. Additionally, the uncertain reopening of the Strait of Hormuz continues to fuel supply concerns.

Furthermore, controlling shareholder Chinalco and parties acting in concert have cumulatively increased their stake by approximately RMB 659 million, signaling confidence in the company's value.
