Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. Core Views Tin - Short - term tin prices are highly volatile due to market sentiment, so cautious participation is advised. In the medium - to - long - term, the supply side is gradually recovering, but considering the low elasticity of the supply side and the long - term narrative of the AI arms race, a low - buying strategy for tin prices is recommended [2]. Industrial Silicon - The spot price of industrial silicon is stable, and the futures price fluctuates, rising after a decline. The production in January and February is expected to decrease. The demand side is likely to decline slightly in January. The price of industrial silicon is expected to fluctuate, with the main price range between 8200 - 9200 yuan/ton. Attention should be paid to the changes in production on the demand side [3]. Polysilicon - The average spot price of polysilicon and the price of silicon wafers have declined. The demand expectation has improved, and component production may increase slightly, which is conducive to inventory digestion. However, polysilicon and silicon wafer prices are under pressure due to high inventory. The monthly average production in the first quarter is expected to drop to about 80,000 tons. The price may be supported at the 48,000 yuan/ton level, and even at 45,000 yuan/ton considering full - cost support [4]. Copper - Market speculative sentiment has eased, and copper prices fluctuated. Geopolitical factors affect market expectations of copper tariffs. The global visible inventory has reached a high level in recent years, and the return of COMEX copper inventory may ease the supply pressure in non - US regions. In the short term, copper prices may return to fundamental pricing, and in the long term, the price bottom center is expected to gradually rise. Attention should be paid to the CL premium and LME inventory changes, with support at 97500 - 98500 [5]. Zinc - Market speculative sentiment has eased, and zinc prices adjusted. The shortage of zinc ore supports prices, and the import window for zinc ore has opened. The supply pressure of refined zinc has been relieved. High zinc prices have suppressed demand, and the downstream operating rate has weakened. Zinc prices are expected to fluctuate in the short term, with support around 23,800. Attention should be paid to zinc ore TC and refined zinc inventory changes [9]. Aluminum - The alumina market showed a weak and volatile trend, with an oversupply situation. Alumina prices are expected to fluctuate widely around the industry's cash - cost line, with the main contract reference range of 2600 - 2900 yuan/ton. The aluminum market is in a high - level volatile pattern. Although macro and policy expectations are positive, the fundamentals are under pressure, with supply increasing and demand being suppressed. Aluminum prices are expected to remain volatile at a high level in the short term, with the main contract reference range of 23000 - 25000 yuan/ton [12]. Nickel - The nickel futures market was volatile. Macro factors and the situation of Indonesian nickel ore quotas affect the market. The overall spot transaction of refined nickel is average. The prices of nickel ore and nickel iron have increased. The demand for stainless steel in the off - season is weak, and the market cost is relatively limited. The inventory pressure has increased. The nickel price is expected to fluctuate widely, with the main contract reference range of 138000 - 148000 [13]. Aluminum Alloy - Cast aluminum alloy prices fluctuated at a high level, with cost being the main driving factor. The supply of scrap aluminum is still tight, and the fundamentals show a situation of weak supply and demand in the off - season. The social inventory has decreased slightly. The ADC12 price is expected to continue the high - level volatile pattern in the short term, with the main contract reference range of 22000 - 23500 yuan/ton [15]. Stainless Steel - Stainless steel prices showed a narrow - range fluctuation and then a late - session rally. Macro factors and raw material supply expectations affect the market. The raw material prices are expected to rise, the supply is relatively loose, and the demand is weak. The social inventory is decreasing, but the demand in the off - season is still insufficient. Stainless steel prices are expected to be strongly volatile in the short term, with the main contract reference range of 14200 - 15000 [16]. Lithium Carbonate - Lithium carbonate futures prices rose sharply. News about lithium concentrate auctions and mine supply fluctuations affected the market sentiment. The production is slightly increasing, and the supply is expected to decline during the pre - holiday maintenance period. The downstream demand shows certain resilience. Social inventory decreased last week. Lithium carbonate prices are expected to be strongly volatile in the short term, but chasing the rise requires attention to volatility and liquidity risks [20].

Report Industry Investment Ratings No relevant information provided. Core Views of the Reports Industrial Silicon - Industrial silicon spot prices are stable, and futures prices are oscillating. It is expected to maintain a weak supply - demand situation in December, with prices fluctuating in the range of 8000 - 9000 yuan/ton, and attention should be paid to the support at 8000 yuan/ton and coal price changes [1]. Polysilicon - Spot prices are stable, and the main contract has risen. Although new delivery brands are beneficial for increasing deliverable volume and warehouse receipts, considering weak demand and a large decline in production, polysilicon futures may still oscillate at a high level, and the spot is still under pressure [2]. Aluminum Alloy - The casting aluminum alloy market is oscillating strongly in the game between strong cost support and weak demand. It is expected to maintain a narrow - range high - level oscillation in the short term, with the main contract reference range of 20700 - 21400 yuan/ton [3]. Aluminum - Alumina is expected to maintain a bottom - oscillation, with the main contract reference range moving down to 2400 - 2700 yuan/ton. Aluminum is expected to run strongly in the short term, with the main contract of Shanghai Aluminum oscillating in the range of 21700 - 22400 yuan/ton [4]. Tin - Market sentiment is positive, and the fundamentals are strong. It is expected that tin prices will maintain a strong trend throughout the year, and a bullish view on tin prices is maintained [6]. Zinc - With the decline of TC, the supply pressure is relieved, and the short - term price has limited downward space. The export of refined zinc drives the spot to tighten, boosting domestic zinc prices. The short - term Shanghai zinc price trend may be stronger than that of London zinc, and the main contract should focus on the support at 23000 - 23200 [8]. Copper - In the short term, the imbalance of global copper supply and inventory drives copper prices to rise rapidly, and price fluctuations may intensify. In the long term, the supply - demand contradiction of copper still exists, supporting the gradual upward movement of the bottom center of copper prices [10]. Nickel - Macro factors are temporarily stable. After the valuation repair of nickel prices, the price driving force weakens. In the medium term, the loose fundamentals restrict the upward space of prices. It is expected to oscillate in a range in the short term, with the main contract reference range of 116000 - 120000 [13]. Stainless Steel - Macro factors are temporarily stable, the supply pressure eases slightly, but the demand in the off - season is weak, and inventory reduction is not smooth. It is expected to oscillate and adjust in the short term, with the main contract operating range of 12400 - 12800 [15]. Lithium Carbonate - The lithium carbonate market is running strongly. Although the fundamentals have not changed much, the market is affected by news of slower - than - expected upstream resumption of production.

Group 1: Industrial Silicon Market Analysis Price and Trading Information - On December 10, 2025, the industrial silicon futures price showed a volatile trend. The main contract 2601 opened at 8305 yuan/ton and closed at 8250 yuan/ton, down 185 yuan/ton (-2.19%) from the previous settlement price. The position of the main contract 2601 was 171,757 lots, and the total number of warehouse receipts was 7780 lots, an increase of 252 lots from the previous day [2]. Supply - Side Information - The spot price of industrial silicon declined slightly. The price of East China oxygen - passed 553 silicon was 9100 - 9300 yuan/ton, 421 silicon was 9500 - 9800 yuan/ton, Xinjiang oxygen - passed 553 silicon was 8600 - 8900 yuan/ton, and 99 silicon was 8600 - 8900 yuan/ton. Silicon prices in Kunming, Huangpu Port, Northwest, Tianjin, Xinjiang, Sichuan, and Shanghai remained flat, and the price of 97 silicon was stable [2]. - The price of silicon coal remained stable for now, but it was expected to loosen in some regions due to the downward - trending prices of raw coal and coking coal. The average price of non - caking silicon coal in Xinjiang was about 825 yuan/ton, the price range of caking silicon coal was about 1300 - 1650 yuan/ton, the average price of silicon coal in Shaanxi was about 880 yuan/ton, in Inner Mongolia was about 1260 yuan/ton, the average price of silicon mixed coal in Gansu was about 930 yuan/ton, and the average price of granular coal was about 1050 yuan/ton [2]. Demand - Side Information - The quoted price of organic silicon DMC was 13500 - 13700 yuan/ton, and the transaction price was also in this range, up 250 yuan/ton from the previous week. As the DMC market price stabilized, the purchasing sentiment of downstream customers became more rational. Due to the weak demand in the terminal market, it would take time for the price to be fully transmitted to the terminal [3]. Strategy - The spot price was affected by the futures market and showed a weak and volatile trend. The industrial silicon futures market declined significantly due to capital sentiment, and attention should be paid to the strength of the lower support. The industrial silicon market was mainly affected by the overall commodity sentiment and policy news. If there were policies to promote capacity exit, the market might rise as the current valuation was low. For single - side trading, short - term range operation was recommended, and long positions could be considered when the price dropped significantly [4]. Group 2: Polysilicon Market Analysis Price and Trading Information - On December 10, 2025, the main contract 2601 of polysilicon futures showed a wide - range volatile trend. It opened at 56000 yuan/ton and closed at 55915 yuan/ton, with a closing price increase of 1.62% from the previous trading day. The position of the main contract was 54959 lots (68874 lots the previous day), and the trading volume was 116207 lots [5]. Supply - Demand and Inventory Information - The spot price of polysilicon weakened slightly. The price of N - type material was 49.60 - 55.00 yuan/kg, and N - type granular silicon was 49.00 - 51.00 yuan/kg. The inventory of polysilicon manufacturers and silicon wafers increased. The latest polysilicon inventory was 29.10 (a 3.38% change from the previous period), the silicon wafer inventory was 21.30GW (a 9.23% change), the weekly polysilicon output was 25800.00 tons (a 7.50% change), and the silicon wafer output was 11.95GW (a - 0.58% change). The estimated polysilicon output in December was 113500 tons, mainly due to production cuts in Inner Mongolia, and there were no major production cut plans in January [5][6]. Component Price Information - The mainstream transaction prices of components were as follows: PERC182mm was 0.67 - 0.74 yuan/W, PERC210mm was 0.69 - 0.73 yuan/W, N - type 182mm was 0.65 - 0.67 yuan/W, and N - type 210mm was 0.67 - 0.69 yuan/W [7]. Strategy - The supply and demand of polysilicon both weakened, with a significant decline in consumption and high inventory pressure. The market was affected by anti - involution policies and weak market reality. After the establishment of the platform company, attention should be paid to the implementation of production and sales restrictions. The market fluctuated greatly recently, and participants should pay attention to risk management. It was expected that the market would mainly fluctuate. For single - side trading, short - term range operation was recommended, and the main contract was expected to fluctuate in the range of 50000 - 57000 yuan/ton [8].

1. Report Industry Investment Ratings No relevant content provided. 2. Core Views of the Reports Industrial Silicon - The price of industrial silicon is expected to remain in a low - level oscillation. In November, the supply and demand of the industrial silicon market will both decline, with a larger decline in supply. However, due to the large supply base and the replenishment of the spot market by cancelled warehouse receipts, there is still expected to be inventory accumulation pressure. The main price fluctuation range is expected to be between 8,500 - 9,500 yuan/ton [1]. Polysilicon - It is expected to maintain a high - level range oscillation. The market is in a situation of both supply and demand decline, with inventory accumulation expected in each link, but strong spot support. The backwardation market structure will remain. For trading strategies, try to go long at around 50,000 for futures; hold or take profit on sell put options for options, and consider buying straddles if volatility decreases [2]. Tin - With strong fundamentals, a bullish view on tin prices is maintained. Hold previous long positions and pay attention to macro - end changes and the recovery of supply in Myanmar [4]. Aluminum - Alumina is expected to maintain a bottom - level oscillation, with the main contract operating in the range of 2,700 - 2,850 yuan/ton. Whether the market can rebound depends on the actual production cut scale of existing enterprises and the inventory inflection point. Electrolytic aluminum is expected to maintain a high - level oscillation, with the Shanghai aluminum main contract operating in the range of 21,100 - 21,700 yuan/ton. Focus on overseas monetary policy trends and domestic inventory destocking rhythm [6]. Zinc - Zinc prices are expected to oscillate. The supply - side pressure has gradually eased, and the demand side has shown a structural improvement. However, the terminal demand has remained stable, and there is limited upward momentum. The main reference range is 22,200 - 22,800 yuan/ton [7]. Copper - In the medium - to - long - term, the supply - demand contradiction supports the upward movement of the bottom center of copper prices. Pay attention to macro - drivers such as overseas interest - rate cut expectations. The main reference range is 85,500 - 87,500 yuan/ton [8]. Nickel - The macro - situation is temporarily stable, and the fundamentals remain weak. However, due to upstream production cuts and low valuations, the market may oscillate and repair. In the medium term, the abundant supply will still restrict the upward space of prices. The main reference range is 116,000 - 120,000 yuan/ton [9]. Aluminum Alloy - The price of ADC12 is expected to maintain an oscillating pattern in the short term, with the main contract operating in the range of 20,300 - 20,900 yuan/ton. Pay attention to the improvement of scrap aluminum supply and the change in downstream procurement rhythm [11]. Stainless Steel - The policy - driven effect is difficult to be directly transmitted in the short term, cost support is weakening, and the fundamental structure has not improved significantly. There is still pressure on the supply - side steel mill production schedule and social inventory, and the demand is weak in the off - season. It is expected to oscillate, with the main operating range of 12,300 - 12,700 yuan/ton [13]. Lithium Carbonate - The market is expected to oscillate and adjust in the short term, with the main reference range of 90,000 - 95,000 yuan. Although the market has a bullish sentiment, there is limited substantial new driving force [15]. 3.

Report Industry Investment Ratings No relevant information provided. Core Views of the Reports Industrial Silicon - The industrial silicon market in November saw a decline in both supply and demand, with a larger decline in supply. However, due to the large supply base and the replenishment of the spot market by cancelled warehouse receipts, there is still pressure to accumulate inventory. In December, the decline in production is expected to narrow, but if the organic silicon industry reduces production, the inventory accumulation pressure will increase. The price is expected to fluctuate between 8,500 - 9,500 yuan/ton, and short positions can gradually take profits at low prices [1]. Polysilicon - The spot price of polysilicon is expected to stabilize. The market is in a situation of both supply and demand decline, but there is still an expectation of inventory accumulation in each link. In the short term, the supply of polysilicon is relatively high, but the long - term supply - demand balance driven by the exit of backward production capacity will support the price. The futures price has fallen back to a reasonable range, and attention should be paid to the support level, as well as the establishment of platform companies, production control, demand changes, and the digestion of warehouse receipts after the November contract cancellation [2]. Aluminum and Alumina - **Alumina**: The market maintains a supply - demand surplus pattern, with short - term supply pressure increasing. The price is expected to remain weakly volatile in the short term, with the main contract reference range of 2,700 - 2,900 yuan/ton. Attention should be paid to the production reduction trends of high - cost enterprises [3][4]. - **Aluminum**: The price will fluctuate between macro - level positive factors and weak fundamentals in the short term. The medium - term supply shortage pattern remains unchanged. Attention should be paid to downstream start - up changes, inventory reduction rhythms, and overseas policy trends [3][4]. Tin - Considering the strong fundamentals, a bullish view on tin prices is maintained. Existing long positions can be held, and attention should be paid to macro - level changes and the recovery of supply from Myanmar [6][7]. Zinc - The fundamentals provide limited support for the continuous upward movement of zinc prices. In the short term, it may still be volatile. An upward breakthrough requires an improvement in demand, and a downward breakthrough requires continuous inventory accumulation. The export of zinc ingots may boost domestic zinc prices, and the short - term main contract reference range is 22,200 - 22,800 yuan/ton [9]. Copper - The market expects the probability of an interest rate cut in December to decline, and the copper price is oscillating weakly. The long - term supply - demand contradiction supports the upward movement of the copper price's bottom center. The main contract reference range is 85,000 - 86,500 yuan/ton, and attention should be paid to changes in demand and overseas interest rate cut expectations [10]. Nickel - The macro - level exerts some pressure, and the improvement in fundamentals is limited. The medium - term supply is abundant, which restricts the upward space of the price. The short - term driving force is weak, and the main contract reference range is 113,000 - 118,000 yuan/ton. Attention should be paid to macro - level expectations and Indonesian industrial policy news [12]. Stainless Steel - Policy and macro - level driving forces are insufficient, and the fundamental structure has not improved significantly. The supply - side pressure from steel mills' production schedules and social inventory remains, and demand is weak. The short - term price is expected to be weakly volatile, with the main contract reference range of 12,300 - 12,600 yuan/ton. Attention should be paid to steel mills' production reduction and nickel - iron prices [16]. Lithium Carbonate - The market is in a situation of both supply and demand growth. The short - term price is expected to be volatile, and the main contract LC2601 has risen. Attention should be paid to the resumption of production of large enterprises, changes in demand after the peak season, and the possible acceleration of the release of upstream projects at high prices. Long positions established earlier can consider partial profit - taking [18].
