Core Views of the Reports Tin - Despite a significant increase in Indonesian exports in November leading to a decline in tin prices, the fundamental situation remains strong. Tin prices are expected to maintain a strong trend for the rest of the year. It is recommended to hold long positions and adopt a strategy of buying on dips, while also keeping an eye on subsequent macro and supply - side changes [1]. Nickel - After the macro - level factors have been digested, the previous upward drivers for nickel prices are limited. With the decline of the Indonesian nickel ore benchmark price and the accelerating inventory accumulation in China, the fundamental situation is loose, which restricts the upside potential of prices. In the short term, the nickel futures market is expected to be weak, with the main contract price ranging from 110,000 to 116,000 yuan. Attention should be paid to the performance around the 110,000 - yuan resistance level and upstream production cuts and Indonesian policy news [2]. Stainless Steel - The supply pressure has slightly eased, and the stop - falling of nickel iron provides cost support. However, the demand is weak in the off - season, and the inventory reduction is insufficient. In the short term, stainless steel is in a game of weak supply and demand. Affected by the weak performance of Shanghai nickel, it is expected to be weakly adjusted, with the main contract price ranging from 12,200 to 12,800 yuan. Attention should be paid to the implementation of steel mill production cuts and marginal improvements in demand [3][5]. Lithium Carbonate - The fundamental situation has not changed much recently, maintaining a situation of strong supply and demand. The inventory reduction in all links last week was about 2,000 tons, and the recent inventory changes are relatively stable. The market's expectations for resumption of production are constantly adjusted, and in the short term, the futures market may maintain a strong trend driven by capital sentiment. However, in the off - season, the new driving forces may be limited, and the recent increase in news - related interference may cause market fluctuations [7]. Zinc - As the domestic zinc ore enters the production - reduction season, the tightness at the ore end may gradually spread to zinc ingots, and the supply side is gradually changing from loose to tight. The export of refined zinc drives the tightness of the spot market and boosts domestic zinc prices. In the short term, the price of Shanghai zinc may be stronger than that of London zinc. In the future, if the TC stops falling and stabilizes, the smelting profit may be repaired, which may drive the increase in zinc ingot production again. Attention should be paid to the TC inflection point and changes in refined zinc inventory, with the main contract focusing on the support around 22,800 yuan [10]. Copper - The global copper supply and inventory are imbalanced, and the tight situation at the ore end still exists, which pushes up the bottom of copper prices. Macro - events such as the release of US inflation data and the Japanese central bank's interest - rate decision this week may intensify short - term price fluctuations. The main contract should focus on the support in the range of 90,000 - 91,000 yuan [11]. Aluminum - For alumina, the oversupply situation remains unchanged, and the price is expected to maintain a bottom - level oscillation, with the main contract price ranging from 2,450 to 2,700 yuan/ton. Attention should be paid to the risk of active profit - taking due to capital reduction. Whether the market can rebound depends on the actual production - cut scale of existing enterprises and whether the inventory shows a clear inflection point. For electrolytic aluminum, supported by strong macro - expectations and real supply risks, the price is expected to be strong in the short term, but high prices may suppress terminal consumption, and the risk of a pull - back after a rise should be vigilant. The main contract of Shanghai aluminum is expected to oscillate in the range of 21,700 - 22,400 yuan/ton, and attention should be paid to changes in macro - expectations and the actual inventory reduction in China [14]. Industrial Silicon - It is expected that the situation of weak supply and demand will continue in December. The industrial silicon price is expected to oscillate at a low level, mainly in the range of 8,000 - 9,000 yuan/ton. If the production decreases significantly, it may break through 10,000 yuan/ton; if the polysilicon production is significantly reduced and the industrial silicon production cut is less than expected, the price may fall to 7,500 yuan/ton. With a large number of current warehouse receipts, investors should pay attention to position management [15]. Polysilicon - The supply exceeds demand, and the inventory continues to accumulate. There is a contradiction between the strong futures market and weak spot demand. The platform company's registration is favorable for price support or an upward trend in sentiment, but the actual supply - demand balance depends on the implementation of capacity storage and production control. Currently, the polysilicon price maintains a high - level oscillation, and the futures price is strongly rising, with a large premium over the spot market. In the future, attention should be paid to the production - cut amplitude or price - fall pressure. The main contract has shifted to 2605, and it is recommended to wait and see for now [17]. Aluminum Alloy - The casting aluminum alloy market is oscillating strongly in the game between strong cost support and weak demand. The cost support is strong due to the shortage of scrap aluminum raw materials and the increase in prices of auxiliary materials such as copper. However, high prices suppress downstream short - term purchasing willingness, and the operating rates of small and medium - sized die - casting enterprises have declined. The ADC12 price has limited downward space but is restricted from rising by high inventory and high prices. It is expected to maintain a high - level narrow - range oscillation in the short term, with the main contract price ranging from 20,700 to 21,400 yuan/ton. Attention should be paid to the improvement progress of scrap aluminum supply and changes in downstream purchasing rhythm [20]. 3.

Report Industry Investment Ratings - Not provided in the given content Core Views Tin - Considering the strong fundamentals, tin prices are expected to remain strong throughout the year. Maintain a bullish view on tin prices, hold existing long positions, and consider buying on dips. Continuously monitor macroeconomic changes and supply - side dynamics [1] Nickel - The nickel market is temporarily stable. After the price valuation is restored, the upward driving force is weak. The decline of the Indonesian nickel ore benchmark price and the accelerating inventory accumulation in China restrict the upside space of prices. In the short - term, the nickel price is expected to fluctuate within a range, with the main contract reference range of 116,000 - 120,000. Pay attention to macro - expectations and Indonesian industrial policy news [3] Stainless Steel - The stainless steel market is temporarily stable. The supply pressure eases slightly, but the demand is weak in the off - season and the inventory reduction is difficult. In the short - term, the low valuation and improved market sentiment will lead to a certain price recovery, but the driving force is limited. The price is expected to fluctuate and adjust, with the main contract reference range of 12,400 - 12,800. Follow the implementation of steel mill production cuts and nickel - iron transactions [5] Lithium Carbonate - The lithium carbonate market has a weak short - term outlook. Although the fundamentals support prices in the short - term, there are limited new positive factors. Facing the resumption of production by large manufacturers and the sustainability of off - season demand, the upward driving force may gradually weaken. It is expected to fluctuate weakly in the short - term, with the main contract reference range of 90,000 - 95,000 [7] Industrial Silicon - The industrial silicon market is expected to maintain a low - level oscillation. The price is mainly expected to fluctuate between 8,500 - 9,500 yuan/ton. If the price drops to around 8,500 - 8,700 yuan/ton, consider buying on dips [9] Polysilicon - The polysilicon market is likely to experience high - level fluctuations. Given the weak demand, the spot price has limited upward momentum, and the futures price is more likely to decline and converge with the spot price. It is recommended to wait and see, and hold existing short positions if any [11] Zinc - In the zinc market, the downward trend of TC eases the supply pressure, and the short - term price has limited downside space. The export of refined zinc tightens the spot market and boosts the domestic zinc price. In the short - term, the Shanghai zinc price may be stronger than the London zinc price. Pay attention to the TC inflection point and refined zinc inventory changes. The main contract reference range is 22,500 - 23,500 [13] Copper - In the copper market, the imbalance of global copper supply and inventory drives the price up rapidly in the short - term, with increased price volatility. In the medium - to long - term, the supply - demand contradiction supports the upward movement of the price center. The main contract should focus on the support level of 90,000 - 91,000 [15] Alumina - The alumina market is in a state of oversupply, and the price is expected to maintain a bottom - level oscillation. The main contract reference range is lowered to 2,550 - 2,800 yuan/ton. The key to a rebound lies in the actual production cuts of enterprises and the inflection point of inventory [17] Aluminum - In the aluminum market, supported by strong macro - expectations and supply risks, the price is expected to remain strong in the short - term. However, high prices may suppress terminal consumption, and there is a risk of a pull - back after the price peaks. The Shanghai aluminum main contract is expected to oscillate between 21,700 - 22,500 yuan/ton next week. Pay attention to the Fed's interest - rate decision and domestic inventory reduction [17] Aluminum Alloy - The aluminum alloy market is expected to maintain a high - level narrow - range oscillation. The strong cost support limits the downside space of the ADC12 price, while high inventory and high prices restrict the upside. The main contract reference range is 20,800 - 21,600 yuan/ton.

Imported ingots are arriving in China, restricting the upward space [1]. - **Consumption**: The terminal consumption has recovered, and the downstream purchasing enthusiasm has improved. The inventories of smelters have decreased [1]. - **Trend**: The fundamentals are improving, but the imported ingot supply is expected to be strong. The upper pressure level is 17,300 yuan/ton [1]. Nickel and Stainless Steel - **Market**: The Shanghai nickel is in a low - level shock, and the stainless steel has a slight rebound. The trading activity is low [1]. - **Macro and demand**: After the interest - rate cut, the long - position holders tend to cash out. The downstream is cautious, and the high - price transactions are difficult. The cost increase momentum is insufficient, but the pre - holiday demand is emerging. The cost support is obvious [1]. - **Supply and inventory**: The premiums of different products are different. The nickel inventory has increased, and the stainless steel inventory has decreased [1]. - **Trend**: The long - position themes of Shanghai nickel are exhausted, and the price is in a weak trend and is about to start a downward trend [1]. Tin - **Market**: The internal and external prices have encountered resistance and declined, and the LME squeeze - out situation has basically ended [1]. - **Supply**: There is a lack of new information. Domestic leading enterprises are under maintenance, and the supply of domestic and overseas raw materials is tight [1]. - **Consumption**: After the price has dropped to the support level, there is a demand for low - price purchases. The inventory has decreased, but the domestic terminal production and exports are average [1]. - **Trend**: After the reduction of the internal and external position risks, the market focus turns to the domestic market. It is difficult for the price to show a trend. A "high - selling and low - buying" trading style is recommended [1]. Lithium Carbonate - **Market**: The futures price has oscillated and rebounded, and the market speculation has declined. The difference between long and short positions has decreased [1]. - **Supply and demand**: The traditional car sales season has driven the growth of material factory orders. The overall industry demand is strong. The total market inventory has decreased, and the smelter inventory has decreased while the downstream inventory has increased [1]. - **Trend**: The low - level support is emerging, but after the industry's selling actions are basically completed, combined with the anti - involution trend, the price is under pressure [1]. Industrial Silicon - **Price**: The prices of industrial silicon and polysilicon have shown different trends. The price of industrial silicon has broken through 9,000 yuan/ton due to cost support [1]. - **Supply and demand**: The production is expected to increase from September to October. The demand side has different situations for different industries. The overall supply is expected to be in an over - supply situation [1]. - **Inventory**: The social inventory has increased, including the increase in ordinary inventory and delivery inventory [1]. - **Trend**: The price is affected by the upward cost of coal and the expectation of eliminating backward furnace types. The supply - demand contradiction suppresses the price, and the upward space is limited [1]. Polysilicon - **Price**: The futures price has oscillated in a range and shown a downward trend. The market sentiment has cooled down. The spot price has a slight upward adjustment [1]. - **Supply and demand**: The output of leading enterprises may decline in October, and the downstream silicon wafers are expected to reduce production, while the component price continues to oscillate [1]. - **Inventory**: The enterprise inventory is unevenly distributed, and the total inventory has decreased [1]. - **Trend**: The elimination of excess capacity is gradually advancing. The market sentiment has a weakened boosting effect. The futures price may face callback pressure, and attention should be paid to the support at 50,000 yuan/ton [1]. Recommended Strategy - Hold long positions in the silver 2512 contract and raise the target price to 10,500 - 12,000, with a stop - loss at 9,100. The reasons are the Fed's dovish stance and the appropriate gold - silver ratio [1].

Core Viewpoints of the Report - The report presents weekly views on various non - ferrous metals, including copper, aluminum, zinc, lead, nickel, stainless steel, tin, lithium carbonate, industrial silicon, and polysilicon. It analyzes the market conditions, supply - demand relationships, and price trends of each metal, and provides corresponding investment suggestions such as position - taking and trading strategies [1] 3. Summary According to Related Catalogs Copper - **Market sentiment**: Affected by the market volatility, interest rate cuts, and the trend of precious metals, copper prices reached a new high since the second half of last year, but there was profit - taking by early long - positions. The market is focusing on real - economy indicators such as September's European and American manufacturing data and August's US PCE [1] - **Domestic situation**: Spot prices are stable, and the market is in the pre - holiday stocking period. Inventories have a small outflow but still accumulate this month. Refined copper production decreased month - on - month, and scrap copper enterprises are reluctant to sell. The market is concerned about the supply supplement from imports [1] - **Overseas situation**: Freeport's Indonesian Grasberg mine has a small amount of production, and the second - stage expansion of Congo's Kakula copper mine is postponed, affecting the production forecast for next year [1] - **Trend**: There is some pre - holiday stocking support, but the pressure on consumption indicators should be continuously monitored. After the early long - positions stop losses, it is advisable to wait and see. The expected range of Shanghai copper is 79,000 - 80,600 yuan [1] Aluminum and Alumina - **Alumina**: The operating capacity increased by 400,000 tons to 9.795 million tons last week, reaching a new high. The market is in an oversupply state, and inventories are increasing. The price is weakly running, with support around 2,000 yuan [1] - **Aluminum**: The domestic operating capacity is stable at around 4 million tons. The downstream processing enterprise's operating rate decreased slightly. Aluminum exports showed a mixed performance. Aluminum ingot social inventories increased slightly, and aluminum rod inventories decreased. The spot discount narrowed, and the processing fee increased [1] - **Trend**: The downstream seasonal improvement is not obvious, and the apparent consumption is lower than expected. The price of Shanghai aluminum has fallen from a high level, with support at 20,500 yuan. It is necessary to pay attention to whether pre - holiday stocking can drive a positive feedback in inventory and spot [1] Zinc - **Market**: After the Fed's short - term interest rate cut, profit - taking led to a decline in zinc prices. The LME inventory is low, and the 0 - 3 - month premium has expanded. The domestic and foreign price trends are divergent, and the import ore ratio is not good [1] - **Supply**: Domestic smelters have maintenance plans in September, and zinc ingot supply is expected to decrease month - on - month. Social inventories have decreased, and the price has support at the 22,000 - yuan integer mark [1] - **Consumption**: The peak season is not prosperous, with weak orders in some industries. Although there is some low - level buying before the holiday, the demand growth expectation is insufficient [1] - **Trend**: Both domestic and foreign zinc ingots are destocking, and the decline space of the Shanghai - to - LME ratio is limited. There is a need for short - term profit - taking of cross - market arbitrage and short - selling funds. It is advisable to seize the opportunity of short - selling on the rebound of Shanghai zinc before the holiday [1] Lead - **Market**: The LME lead is under pressure, while the Shanghai lead has a phased improvement in fundamentals and rebounds with increased positions [1] - **Supply**: The overseas supply is tight, and the import loss has narrowed. The raw material supply at the mine end is tight, and some smelters may advance their winter shutdowns. The profit of secondary lead has recovered, but the overall operating rate is still low [1] - **Consumption**: Terminal consumption has recovered, and the downstream purchasing enthusiasm has improved before the holidays. The inventories of major lead - zinc smelters and secondary lead smelters have decreased [1] - **Trend**: The fundamentals of lead have improved, but the expected inflow of imported ingots may put pressure on the price rebound. Attention should be paid to the pressure at 17,300 yuan/ton [1] Nickel and Stainless Steel - **Market**: Shanghai nickel fluctuated at a low level, and Shanghai stainless steel rebounded slightly, but the trading activity was low [1] - **Macro and demand**: After the interest rate cut, long - positions tend to cash out. The downstream market is cautious, and high - price transactions are difficult. The cost increase momentum is insufficient, but the pre - holiday demand is emerging, and the cost support is obvious [1] - **Supply**: The premiums of various forms of nickel have different levels, and the inventories of nickel and stainless steel have changed. The inventory of pure nickel increased, the inventory of nickel goods decreased, and the inventory of stainless steel decreased [1] - **Trend**: The long - position themes of Shanghai nickel are exhausted, and the price is weakly running and is about to start a downward trend [1] Tin - **Market**: The prices of domestic and foreign tin encountered resistance and declined, and then found support at the MA400 moving average or lower levels. The LME squeeze is basically over [1] - **Supply**: There is a lack of new information. Domestic leading enterprises are under maintenance, and the supply of domestic and imported tin ore is tight. Indonesia's tin production target remains unchanged [1] - **Consumption**: After the price adjustment, there is some rigid - demand buying. The inventories in some statistics have decreased, but the domestic terminal production and exports are average [1] - **Trend**: After the reduction of the position - taking risk, the market focus turns to the domestic market. Tin prices are difficult to show a trend, and it is advisable to continue the "high - selling and low - buying" trading strategy [1] Lithium Carbonate - **Market**: The futures price of lithium carbonate rebounded with low - volume trading. The market speculation degree has decreased, and the difference between long and short positions has narrowed [1] - **Supply**: The total market inventory decreased by 1,000 tons to 137,500 tons, the smelter inventory decreased by 1,800 tons to 34,000 tons, and the downstream inventory increased by 1,200 tons to 59,600 tons [1] - **Demand**: Driven by the "Golden September and Silver October" in the traditional automobile sales season, the orders of material factories have increased significantly this month, and the overall industry demand is strong [1] - **Trend**: The low - level support is emerging, but after the industry's selling action is basically completed, combined with the anti - involution trend, the price is expected to be under pressure [1] Industrial Silicon - **Market**: The prices of industrial silicon and polysilicon diverged last week. The price of industrial silicon broke through the 900 - yuan/ton mark, mainly due to the cost support from coal production cuts in Xinjiang [1] - **Supply**: The production in September - October is expected to continue to increase, and the production reduction may be clear around the National Day. The production in the southwest is relatively stable [1] - **Demand**: The operating rate of polysilicon in September changed little, and the reduction expectation of leading enterprises in October has increased. The operating rate of organic silicon monomer factories is stable [1] - **Inventory**: The social inventory of industrial silicon increased by 4,000 tons to 543,000 tons [1] - **Trend**: The price of industrial silicon is affected by the rising coal cost and the expected elimination of backward furnace types. The supply - demand contradiction suppresses the price, and the upward space is limited [1] Polysilicon - **Market**: The futures price of polysilicon fluctuated in a range and showed a slight decline. The market sentiment cooled down. The energy - consumption limit standard is in the solicitation stage [1] - **Supply**: After the industry self - discipline meeting, the production of leading enterprises in October may decline, and the downstream silicon wafers are expected to reduce production synchronously [1] - **Inventory**: The inventory of polysilicon enterprises is unevenly distributed, and the total factory inventory decreased by 25,000 tons to 204,000 tons [1] - **Trend**: The capacity elimination of polysilicon is gradually advancing, and the spot price has a slight upward shift. The futures may face callback pressure, and attention should be paid to the support at 50,000 yuan/ton [1] Investment Recommendation - Hold long positions in the silver 2512 contract and raise the target price to 10,500 - 12,000, with a stop - loss at 9,100, due to the Fed's dovish stance and the appropriate gold - silver ratio [1]
