Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Viewpoints - The overall atmosphere in the commodity market was weak yesterday, and the prices of finished steel products showed a weak and volatile trend. If the subsequent demand cannot be effectively repaired, steel prices may not maintain the current level, and the futures prices may gradually return to the supply - demand logic. Attention should be paid to the repair progress of terminal demand and the support of the cost side [4]. - The short - term price of iron ore may be slightly adjusted due to the weakening of terminal demand. It is necessary to pay attention to the subsequent shipping progress and the contradiction between high - level hot metal production and terminal demand [7]. - For ferrosilicon and manganese silicon, it is recommended that investment positions be mainly on the sidelines, while hedging positions can still participate opportunistically. The final price will move closer to the fundamentals after the sentiment fades, and it is necessary to pay attention to the changes in downstream terminal demand [8][9][10]. - Industrial silicon prices are expected to fluctuate weakly, and polysilicon prices are expected to fluctuate widely. Attention should be paid to the resumption of production in major production areas and the impact of policies [13][14][15]. - In the short term, glass and soda ash are expected to fluctuate. In the long term, glass prices follow macro - sentiment fluctuations, and soda ash prices are affected by supply - side and market sentiment under the "anti - involution" logic [17][18]. 3. Summary by Category Steel - Prices and Positions: The closing price of the rebar main contract was 3155 yuan/ton, down 33 yuan/ton (- 1.03%) from the previous trading day. The closing price of the hot - rolled coil main contract was 3419 yuan/ton, down 20 yuan/ton (- 0.58%) from the previous trading day. The positions of both decreased [3]. - Fundamentals: Rebar demand decreased significantly this week, inventory accumulation accelerated, while hot - rolled coil demand recovered significantly, and inventory accumulation slowed down. Both rebar and hot - rolled coil inventories are rising marginally, with high production but insufficient demand [4]. Iron Ore - Prices and Positions: The main contract of iron ore (I2601) closed at 772.00 yuan/ton, with a change of - 0.52% (- 4.00), and the position increased by 1577 hands to 44.89 million hands [6]. - Fundamentals: Overseas iron ore shipments and arrivals increased. The daily average hot - metal output increased, and port and steel mill inventories both increased. Terminal demand weakened, and short - term prices may be adjusted [7]. Ferrosilicon and Manganese Silicon - Prices: On August 18, the manganese silicon main contract (SM509) closed flat at 6026 yuan/ton, and the ferrosilicon main contract (SF511) fell 0.88% to 5880 yuan/ton [8]. - Market Suggestion: Investment positions are recommended to wait and see, while hedging positions can participate according to their own situation. The "anti - involution" sentiment still disturbs the market, and prices will gradually return to fundamentals [8][9]. Industrial Silicon and Polysilicon - Industrial Silicon - Prices and Positions: The main contract of industrial silicon (SI2511) closed at 8605 yuan/ton, down 2.27% (- 200). The weighted contract position increased by 20923 hands to 552911 hands [12]. - Fundamentals: The problems of over - capacity, high inventory, and insufficient demand have not changed. The operating rate is expected to rise in August, and prices are expected to fluctuate weakly [13][14]. - Polysilicon - Prices and Positions: The main contract of polysilicon (PS2511) closed at 52280 yuan/ton, down 0.87% (- 460). The weighted contract position decreased by 1658 hands to 321203 hands [14]. - Fundamentals: The weekly output increased, inventory clearance was limited, and prices are expected to fluctuate widely [15]. Glass and Soda Ash - Glass - Prices and Inventory: The spot price in Shahe was 1160 yuan, down 4 yuan from the previous day. The national floating - glass inventory increased, and the inventory days increased. The market sentiment has been digested, and prices are expected to fluctuate in the short term [17]. - Long - term Outlook: In the long term, it follows macro - sentiment fluctuations, and if there are substantial real - estate policies, prices may rise [17]. - Soda Ash - Prices and Inventory: The spot price was 1260 yuan, down 20 yuan from the previous day. The total inventory of domestic soda ash manufacturers increased slightly. Prices are expected to fluctuate in the short term [18]. - Long - term Outlook: In the long term, under the "anti - involution" logic, prices are affected by supply - side and market sentiment, but the rise is limited by demand [18].
