多晶硅：多单持有，工业硅：等待回调充分

Report Industry Investment Rating - For polysilicon: Hold long positions [1] - For industrial silicon: Wait for a full correction [1] Core Viewpoints of the Report - In the polysilicon market, with progress in capacity integration and expected improvement in supply - demand, polysilicon futures are expected to rise and may hit a new high since listing. In the industrial silicon market, although the current inventory structure and production - demand situation lead to a weak price trend, the short - term downward space is limited, and long positions can be considered after a full correction [5][7] Summary by Relevant Catalogs Chapter 1: Comprehensive Analysis and Trading Strategies Polysilicon - Supply - demand analysis: In October, silicon wafer production increased by 3GW to 62GW, corresponding to a polysilicon demand of about 124,000 tons. Polysilicon production was around 130,000 tons, with a slight inventory build - up. The current total inventory is about 500,000 tons. In November, southwest polysilicon capacity may significantly reduce production, and silicon wafer production is likely to stay above 50GW [5] - Trading logic: The main short - term negative factor is the non - transferable warehouse receipts of the November contract, but their impact on prices is limited. High - inventory manufacturers have no incentive to lower prices, so the spot price is expected to be stable with an upward bias in the short and medium term [5] - Operation strategy: Hold long positions for single - side trading; conduct reverse arbitrage for the 2511 and 2512 contracts; sell put options and buy call options [6] Industrial Silicon - Supply - demand analysis: This week, DMC weekly production decreased by 2.73% to 46,300 tons, polysilicon weekly production decreased by 1.28% to 31,500 tons. The operating rate of primary aluminum alloy increased by 0.2 percentage points to 58.4%, and that of recycled aluminum alloy decreased by 0.3 percentage points to 58.6%. Industrial silicon weekly production increased by 2.09% to 97,500 tons. The total number of open furnaces remained at 318. Industrial silicon social inventory increased by 0.7 million tons to 562,000 tons, sample enterprise inventory increased by 0.57 million tons to 170,600 tons, and downstream raw material inventory decreased by 0.2 million tons to 23,900 tons [7][27][28] - Trading logic: The current inventory structure is "low at both ends and high in the middle", prone to positive feedback between futures and spot. The resumption of production by leading manufacturers and the expected decline in polysilicon production in November have led to weak futures prices. However, the acceptance of high - priced industrial silicon by downstream has increased, and the actual transaction price of spot has not significantly decreased. The short - term downward space is limited [7] - Operation strategy: Close short positions for single - side trading; no options or arbitrage strategies are recommended for now [8] Chapter 2: Industrial Silicon Fundamental Data Tracking - Market trend: This week, industrial silicon futures fluctuated weakly, with the main contract closing at 8,430 yuan/ton on Friday. The spot price decreased by 50 - 100 yuan/ton [11] - Downstream demand: DMC production decreased by 2.73%, polysilicon production decreased by 1.28%, the operating rate of primary aluminum alloy increased by 0.2 percentage points, and that of recycled aluminum alloy decreased by 0.3 percentage points [14] - Production: Industrial silicon production increased by 2.09% to 97,500 tons this week. Yunnan, Sichuan, and Gansu reduced the number of open furnaces, while Xinjiang's leading manufacturers increased the number of open furnaces, and there are rumors of further increases [27] - Inventory: Industrial silicon social inventory increased by 0.7 million tons to 562,000 tons, sample enterprise inventory increased by 0.57 million tons to 170,600 tons, and downstream raw material inventory decreased by 0.2 million tons to 23,900 tons [28] - Related product prices: Industrial silicon spot prices weakened this week, while DMC and terminal product prices of organic silicon increased slightly [33][38] - Raw material prices: The price of Xinjiang refined coal decreased [50] Chapter 3: Polysilicon Fundamental Data Tracking - Price trend: This week, polysilicon spot prices increased. N - type polysilicon prices were in the range of 49.5 - 55 yuan/kg, and some low - price ranges of N - type re -投料 increased by 500 yuan/ton. Silicon wafer and battery prices remained stable, while some component prices increased [56][63][72] - Component fundamentals: Domestic component orders are average, with a neutral to high inventory. Component production in October decreased slightly to 46GW [81] - Battery fundamentals: Battery export demand is good, with a neutral inventory of 6.63GW. Due to the decrease in component production in October, battery production increased to 56GW [88] - Silicon wafer fundamentals: This week, the operating rate of silicon wafer enterprises increased, with a weekly production of 14.35GW. Silicon wafer inventory is 17.31GW, and the production in October was 62GW, an increase of 3GW compared to August [93] - Polysilicon fundamentals: This week, polysilicon production slightly decreased, and factory inventory increased slightly to 253,000 tons. The expected production in October is about 130,000 tons [98]
