Chalco Stock Surges on Parent's Planned Stake Increase and Record Profit Outlook

Summary
Shares in Aluminum Corp. of China rallied after its controlling shareholder announced plans to buy up to RMB 20 billion in stock, a move bolstered by the company's forecast for record first-half profits.
Shares of Aluminum Corp. of China (Chalco) surged in Monday trading after its controlling shareholder unveiled a substantial plan to increase its stake in the company, a move reinforced by a forecast for record semi-annual profits.
Chalco's Hong Kong-listed shares closed up 4.7% at HK$7.97 on July 20, 2026, after touching an intraday high of HK$8.08.
Dual Catalysts Drive Rally
The rally was driven by two key developments disclosed by the state-owned aluminum producer. First, its parent company, Chinalco Group, announced a plan to purchase company shares on both the Shanghai and Hong Kong exchanges over the next 12 months.
According to a market filing, the planned investment includes:
- A total value between RMB 10 billion and RMB 20 billion.
- A purchase cap of 2% of the company's total share capital.
AdThis signal of confidence from the controlling shareholder was amplified by a strong preliminary earnings report. Chalco projected its net profit for the first half of 2026 to be between RMB 11.2 billion and RMB 12.2 billion, representing a year-on-year increase of 58% to 73%. The company described this as the best interim result in its history.
Coordinated Support for Chinese Equities
Chinalco's move was not an isolated event. It was part of a coordinated wave of stake-increase and share buyback announcements from several major Chinese state-owned enterprises (SOEs) released before the market opened on Monday.
Market observers interpreted these simultaneous actions as a deliberate effort by state-backed capital to stabilize investor sentiment and affirm the long-term value of Chinese blue-chip equities. The broader market was also positive, with Hong Kong's Hang Seng Index gaining roughly 2.1% during the session.
