Core Viewpoint - The article emphasizes the importance of selecting stocks based on three criteria: high capacity-to-market value ratio, ability to expand overseas, and the current bottoming of alumina prices, suggesting a focus on companies with high self-sufficiency in alumina amid potential supply disruptions [1][3][4] Supply Side - Global supply elasticity is decreasing and vulnerability is increasing due to factors such as peak domestic capacity in China, energy constraints in Europe and the US, and power supply issues in Indonesia, leading to a projected global supply CAGR of 1.4% from 2025 to 2030 [3][5] - China's electrolytic aluminum production capacity is nearing its limit, with a forecasted production of 4,430 million tons in 2025, reflecting a growth rate of only 2.4% [9] - The US and Europe face challenges in restoring electrolytic aluminum capacity due to high energy costs and tight power supplies, which will slow down recovery and limit new capacity [10][11] - Indonesia is expected to contribute significantly to future global electrolytic aluminum growth, but power supply constraints will hinder rapid capacity release [13][16] Demand Side - Global aluminum demand is projected to grow at a CAGR of 2.3% from 2025 to 2030, driven by traditional demand recovery and emerging sectors like energy storage and data centers [18][22] - Traditional demand is expected to benefit from fiscal and monetary easing, with a projected decrease in the real estate sector's contribution to aluminum demand [22][23] - New industries, particularly energy storage and data centers, are becoming significant drivers of aluminum demand, with projected CAGRs of 26% and 13% respectively from 2025 to 2030 [26][30] Cost Factors - Alumina prices are expected to rebound due to supply-side constraints and policy changes in Guinea, despite current oversupply conditions [36][38] - The energy transition is anticipated to lower the costs of green electricity for electrolytic aluminum production, although short-term carbon taxes may raise energy costs [40][56] - Coal prices are expected to remain low, which will help suppress the costs of thermal power generation for electrolytic aluminum [41] Growth Opportunities - The Chinese aluminum industry is accelerating its overseas expansion due to domestic resource shortages and capacity constraints, with significant investments in regions like Guinea and Southeast Asia [42][45] - Guinea is highlighted as a key player in the alumina market, with plans to enhance local processing capabilities and attract investment [46] - Indonesia is emerging as a major hub for the aluminum industry, supported by government policies aimed at developing its domestic aluminum value chain [47] - Angola's rich hydropower resources and supportive policies are attracting investments in electrolytic aluminum production [48][49] - The Middle East is positioned as a cost-competitive region for aluminum production due to its abundant natural gas resources [50][51] Price Outlook - The electrolytic aluminum sector is expected to experience a revaluation as supply constraints and rising demand support higher aluminum prices, with potential for significant profit expansion [52][55] - The article suggests that the sector is transitioning from a purely cyclical nature to one that also includes dividend stability, making it an attractive investment opportunity [58]
