Shares of Aluminum Corporation of China (Chalco, 02600.HK) surged 5.01% in intraday trading on Tuesday, as investors reacted positively to the company's impressive third-quarter financial results and a strategic investment announcement.

Chalco reported a significant jump in its Q3 net profit, which increased by 90.31% year-over-year to RMB3.8 billion. This substantial profit growth came despite a slight dip in revenue, which fell 4.66% to RMB60.12 billion. The company attributed its strong performance to effective cost control measures and improved operational efficiency. For the first nine months of the year, Chalco's profit reached RMB10.87 billion, marking a 20.65% increase compared to the same period last year.

Adding to the positive sentiment, Chalco announced that its subsidiary, Yun Aluminum, has invested RMB500 million in Yunnan Aluminum Foil. This move is part of a larger capital contribution totaling RMB906.45 million, involving Chinalco High-End, Yunnan Aluminum, and Kunming Copper. Upon completion of the capital contribution, Yunnan Aluminum Foil's registered capital will increase to RMB1,147.3973 million, potentially strengthening Chalco's position in the aluminum processing sector.

The stock's strong performance comes amid a generally positive sentiment in the Hong Kong market, with the Hang Seng Index ADRs rising 0.34% to 26,523.81 points. Chalco's upward movement aligns with the broader trend of Chinese asset revaluation, as highlighted by CSRC Chairman Wu Qing at the recent 2025 Financial Street Forum, where he emphasized the growing preference for stability and balance in asset allocation.
