1. Report Industry Investment Rating - Industrial silicon: Weak operation [1] - Polysilicon: Monitor the registration of warehouse receipts 2. Core Viewpoints - The report provides comprehensive data on the fundamentals of industrial silicon and polysilicon, including futures market prices, trading volumes, open interests, basis, spot prices, profits, inventories, and raw material costs. It also mentions relevant macro and industry news and the trend intensity of industrial silicon and polysilicon [2][4] 3. Summary of Relevant Catalog 3.1 Fundamentals Tracking - Futures Market: Si2601 closing price was 8,910 yuan/ton, down 10 yuan from T - 1; PS2601 closing price was 56,915 yuan/ton, down 515 yuan from T - 1. Trading volumes and open interests of both showed different degrees of change [2] - Basis: Industrial silicon and polysilicon had various basis values against different benchmarks, with some showing changes compared to previous periods [2] - Prices: The prices of industrial silicon, polysilicon, and related products such as silicon wafers, battery cells, and components had different price trends. For example, the price of polysilicon - N - type re - feedstock was 52,300 yuan/ton, down 50 yuan from T - 1 [2] - Profits: Silicon factory profits in Xinjiang and Yunnan were negative; polysilicon enterprise profit per kilogram was 7.7 yuan, up 0.4 yuan from T - 1 [2] - Inventories: Industrial silicon social inventory (including warehouse receipt inventory) was 55.8 + 18.3 (the data format seems to have an error here), and polysilicon factory inventory was 29.1 tons [2] - Raw Material Costs: The prices of raw materials such as silicon ore, washed coking coal, petroleum coke, and electrodes in different regions had different trends and remained stable in most cases [2] 3.2 Macro and Industry News - On November 30, the Beijing Economic - Technological Development Area Management Committee issued the "Several Measures on Promoting Green and Low - Carbon High - Quality Development (Version 2.0)". The goal is to achieve new breakthroughs in green and low - carbon key technology research by 2027, and make new progress in various aspects such as new - quality productivity, new energy vehicle promotion, and carbon peaking and carbon neutrality [2][4] 3.3 Trend Intensity - Industrial silicon trend intensity: 0; Polysilicon trend intensity: 0. The trend intensity ranges from - 2 (most bearish) to 2 (most bullish) [4]
