Report Industry Investment Rating - Not provided in the content Core Viewpoints - The industrial silicon market is running weakly, with prices breaking through support levels. In the short - term, after a smooth decline, attention should be paid to the rebound near technical support levels. The supply reduction of industrial silicon has reached a bottleneck, and demand support is weakening. The short - term price is expected to be weak, but it may rebound if the sentiment of "anti - involution" related commodities improves. For polysilicon, there is a significant divergence between expectations and reality. The expected "anti - involution" is strong, but the downstream reality is weak. The inventory accumulation pressure before the Spring Festival is difficult to relieve, and attention should be paid to the pressure performance at the 60,000 - yuan mark on the disk [16][18] Summary by Directory 01.

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. In the short term, it may maintain a strong oscillation under the drive of capital sentiment [18].

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].
