多晶硅：短期震荡，工业硅：短期或有回调

Report Industry Investment Rating - Not provided in the content Core Viewpoints - For polysilicon, the long - term price upward trend is certain, recommended to buy on dips in the medium - long term; short - term is volatile, and there may be a deep correction in futures prices. For industrial silicon, the short - term price may correct, but the decline is limited, and it is recommended to participate in long positions after a sufficient correction [4][6] Summary by Directory Chapter 1: Comprehensive Analysis and Trading Strategies - Polysilicon: In September, silicon wafer production is expected to increase by 6GW to 58GW, corresponding to a polysilicon demand of about 116,000 tons. The polysilicon production is expected to remain around 130,000 tons. The total inventory in the polysilicon industry is close to 400,000 tons, and the downstream inventory is about 180,000 - 200,000 tons. Long - term price is likely to rise, short - term is volatile. Operation strategies include buying on dips for far - month contracts, and conducting reverse arbitrage for 2511 and 2512 contracts [4][5] - Industrial silicon: This week, DMC weekly production increased by 0.62% to 48,900 tons, polysilicon weekly production decreased by 0.60% to 31,200 tons, primary aluminum alloy operating rate increased by 1 percentage point to 57.6%, and recycled aluminum alloy operating rate remained flat at 55.5%. Industrial silicon weekly production increased by 2.75% to 95,500 tons. Social inventory increased by 20,000 tons to 539,000 tons, sample enterprise inventory increased by 3,100 tons to 176,700 tons, and downstream raw material inventory decreased by 2,700 tons to 221,600 tons. The short - term price may correct, and it is recommended to avoid short - term long positions, sell out - of - the - money put options or participate in long positions after a sufficient correction, and conduct reverse arbitrage for 11 and 12 contracts [6][7] Chapter 2: Industrial Silicon Fundamental Data Tracking - Market Performance: This week, industrial silicon futures fluctuated strongly, with the main contract closing at 8,745 yuan/ton. Spot prices generally rose by 100 yuan/ton [10] - Downstream Demand: DMC production increased, polysilicon production slightly decreased, and aluminum alloy operating rate increased. DMC weekly production was 48,900 tons, polysilicon weekly production was 31,200 tons, primary aluminum alloy operating rate was 57.6%, and recycled aluminum alloy operating rate was 55.5% [13] - Production: This week, industrial silicon weekly production was 95,500 tons, a 2.75% increase. The number of furnaces in Xinjiang increased by 7, and it is expected that industrial silicon production will increase slightly in the future [25] - Inventory: Social inventory increased by 20,000 tons to 539,000 tons, sample enterprise inventory increased by 3,100 tons to 176,700 tons, and downstream raw material inventory decreased by 2,700 tons to 221,600 tons [26] - Product Prices: Industrial silicon spot prices strengthened, organic silicon - related product prices were stable, organic silicon intermediate operating rate increased slightly, and aluminum alloy operating rate increased slightly. Xinjiang refined coal prices and charcoal prices rose [31][35][41][45][48] Chapter 3: Polysilicon Fundamental Data Tracking - Price: This week, polysilicon spot prices decreased. N - type re - feedstock price was 49.1 - 54 yuan/kg, N - type dense material price was 48.1 - 52 yuan/kg, and N - type granular silicon price was 48 - 49 yuan/kg. The lower limit of rod - shaped silicon price decreased by 1,000 yuan/ton compared with last week, and granular silicon price remained stable [54][61] - Silicon Wafer and Battery: Silicon wafer and battery prices strengthened. Leading enterprises raised silicon wafer quotes, and battery prices increased accordingly. It is expected that battery quotes may continue to rise [62][68] - Component: Some component prices increased. Domestic photovoltaic component prices increased, and the cost - side supported the price increase. Some projects have accepted higher prices [69] - Fundamental Data: Component domestic orders are average, inventory is moderately high, and the production schedule in September is slightly increased to 45GW. Battery export demand is good, inventory is moderately high, and the production schedule is increased to 57GW. Silicon wafer enterprise operating rate increased, weekly production reached 13.88GW, inventory is 16.55GW, and the production in September is expected to be 58GW. Polysilicon production decreased slightly this week, and factory inventory increased to 234,200 tons. The production in September is expected to be flat compared with August, around 130,000 tons [77][83][88][93]
