1. Report Industry Investment Ratings No relevant information provided. 2. Core Views of the Reports Aluminum - The market surplus pressure of alumina remains severe, and its price is expected to fluctuate widely around the industry cash - cost line, with the main contract reference range of 2600 - 2950 yuan/ton. The key to a trend - like rebound lies in subsequent capacity control policies or large - scale substantial production cuts [1]. - The strong macro and policy expectations provide a solid bottom for aluminum prices, but the weakening supply - demand fundamentals and inventory accumulation pressure will significantly limit the upside space. Aluminum prices are expected to fluctuate widely at high levels in the short term, with the main contract of Shanghai Aluminum operating in the range of 23200 - 24400 yuan/ton [1]. Carbonate Lithium - The supply of carbonate lithium is expected to increase slightly, and downstream demand maintains a certain resilience. However, there is limited new driving force in essence. After the holiday, the news has significantly boosted the sentiment of the non - ferrous sector. The market is expected to fluctuate strongly, and attention should be paid to the breakthrough around 130,000 yuan [2]. Aluminum Alloy - The price of ADC12 is expected to continue to fluctuate in a high - level range in the short term, with the main contract reference range of 22400 - 23400 yuan/ton. Attention should be paid to raw material supply, import window changes, and the actual stocking rhythm of downstream enterprises before the Spring Festival [3]. Tin - The market sentiment has fluctuated greatly recently, causing tin prices to fluctuate sharply. It is advisable to operate with caution, and subsequent attention should be paid to the macro situation and the recovery of the supply side [5]. Industrial Silicon - In January, industrial silicon is expected to continue the pattern of weak supply and demand, and the futures price is under pressure. It is still expected that the price of industrial silicon will fluctuate at a low level, with the main price fluctuation range of 8000 - 9000 yuan/ton [7]. Polysilicon - The spot price of polysilicon has increased, and the futures price has risen and then fallen. In January, the demand is weak, and there is pressure for further production cuts to balance supply and demand. It is recommended to wait and see for the time being, and pay attention to the production cut situation and price adjustment acceptance [9]. Nickel - The recent expectation of Indonesia's increased control over nickel mines has boosted market sentiment, but the weak fundamentals still restrict the upside space of prices. The disk is expected to maintain a strong - side operation, with the main reference range of 130,000 - 138,000 yuan. Attention should be paid to the possibility of a callback after the impact of the news is digested [10]. Stainless Steel - The supply pressure of stainless steel has eased slightly, and the cost support of ore and ferronickel has been strengthened, but the demand in the off - season is still insufficient. The disk is expected to maintain a strong - side shock adjustment, with the main reference range of 12800 - 13500 yuan. Attention should be paid to the ore - end news and downstream stocking [11]. Zinc - Affected by the Venezuela event, zinc prices rose sharply. The supply of domestic zinc concentrates is tight, and the supply pressure of refined zinc has been relieved. The demand side is performing well. In the short term, the price will fluctuate strongly in a warm macro - environment, and attention should be paid to import profit and loss, TC inflection points, and refined zinc inventory changes [12]. Copper - The medium - and long - term fundamentals of copper are still good, but in the short term, the previous sharp rise in prices has suppressed real demand. Although the current price is over - valued to some extent, it may still maintain a strong trend in a high - risk - preference environment, with the main contract paying attention to the 95500 - 96000 support [13]. 3.

Investment Rating - The investment rating for the tin industry is "Outperform the Market" (maintained) [1] Core Insights - Tin is an essential minor metal with increasing resource scarcity. As of the end of 2024, global tin reserves are estimated at 4.2 million tons, with a production of 300,000 tons. The reserve-to-production ratio has decreased from around 20 years in 2010 to 14 years in 2024, indicating a low level of reserves compared to production [2][21] - Global tin supply is expected to decline significantly by 2025 due to decreasing ore grades and various unpredictable factors affecting major production areas. China, the largest producer, has seen a decline in domestic production since 2015 due to lower ore grades and stricter environmental regulations [2][21] - Demand for tin is projected to remain stable or increase, driven by the semiconductor industry and other applications. The global demand for tin is expected to reach 386,000 tons in 2025, with a steady growth forecast through 2027 [2][21] - A significant shortage of refined tin is anticipated in 2025, with a projected supply-demand gap of approximately 16,000 tons. This gap may narrow in subsequent years as production resumes in Myanmar and new projects come online [2][21] - Key companies in the industry include Xiyang Co., Xingye Yinxin, and Huaxi Nonferrous [2] Summary by Sections Industry Overview - Tin is characterized by its low melting point and good conductivity, making it irreplaceable in solder applications. The global distribution of tin reserves is concentrated in a few countries, with China holding the largest share [2][21] Supply Dynamics - The global tin supply has been stable around 300,000 tons in recent years, but significant declines are expected due to various factors affecting major production areas, including environmental regulations and resource depletion [2][21] Demand Dynamics - The semiconductor sector is a major driver of tin demand, with a strong correlation to electronic product production. The demand for tin in solder applications is expected to grow, supported by a recovery in semiconductor sales [2][21] Price Trends - Tin prices have seen significant fluctuations, with a notable increase of 46% since early 2024. The average price for tin in 2024 is projected to be 248,300 yuan per ton, reflecting a year-on-year increase of 16.92% [12][21] Regional Insights - China's tin production has been on a downward trend, with production expected to be 69,000 tons in 2024, down from previous highs. Despite this, China remains the largest producer and holder of tin reserves globally [34][21]
