Report Industry Investment Ratings No relevant content provided. Core Views of the Report - For tin, considering the strong fundamentals, maintain a bullish view on tin prices. Hold existing long positions and adopt a strategy of buying on dips. Pay attention to macro - level changes and supply - side recovery [2]. - For industrial silicon, expect prices to remain in a low - level oscillation, with the main price fluctuation range between 8500 - 9500 yuan/ton. The market will maintain weak supply and demand in December [4]. - For polysilicon, the market is expected to be oversupplied in December with inventory accumulation expected in each link. Futures should be put on hold for now, and out - of - the - money put options can be bought on the options side when volatility is low [5]. - For zinc, the short - term price has limited downside space, but the fundamentals also provide limited elasticity for continuous upward movement. Prices are likely to oscillate. Pay attention to the inflection point of TC and changes in refined zinc inventory [7]. - For copper, the medium - and long - term supply - demand contradiction supports the upward shift of the bottom center of copper prices. Pay attention to overseas interest - rate cut expectations and smelting - end production cuts [8]. - For nickel, the overall driving force is still limited. Short - term prices are expected to oscillate within a range. Pay attention to macro - level expectations and Indonesian industrial policy news [11]. - For stainless steel, the short - term low - valuation situation may lead to some price recovery, but the driving force is limited. Prices are expected to remain weakly oscillating. Pay attention to steel mills' production cut implementation and nickel - iron prices [14]. - For aluminum, alumina prices are expected to remain in a bottom - level oscillation. Aluminum prices are expected to remain strong in the short term [15]. - For lithium carbonate, the short - term price has support, but the unilateral driving force is weakened. The market is expected to oscillate widely around 95,000 yuan [16]. - For aluminum alloy, the short - term price trend of the casting aluminum alloy market is still strong. Pay attention to the improvement of scrap aluminum supply and the sustainability of inventory reduction [18].
