Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Viewpoints - As the "anti - involution" sentiment cools and the Politburo meeting's impact fades, the market sentiment becomes rational, and the futures prices start to weaken. If the demand cannot be effectively restored, the steel prices may decline, and the futures prices will gradually return to the supply - demand logic [3]. - The overall demand for the black sector is weak. Although the supply pressure is not significant, the demand growth is limited. The market is influenced by short - term sentiment, and prices will eventually move towards the fundamentals [3][6][10]. - For different products, the fundamentals vary. For example, steel products have high inventory and weak demand; the supply of iron ore is in the traditional off - season, and the demand has support; the over - capacity situation of industrial silicon and polycrystalline silicon remains unchanged; glass and soda ash have inventory pressure and weak demand [3][6][11][14][16][18][19]. 3. Summary by Product Steel Products - Prices and Positions: The closing price of the rebar main contract was 3250 yuan/ton, up 37 yuan/ton (1.151%) from the previous trading day. The registered warehouse receipts increased by 579 tons, and the position increased by 515 lots. The closing price of the hot - rolled coil main contract was 3465 yuan/ton, up 37 yuan/ton (1.079%), with a decrease of 1454 tons in registered warehouse receipts and 17218 lots in position [2]. - Fundamentals: Rebar showed a pattern of both supply and demand increasing, with social inventory accumulating for two consecutive weeks and the increase accelerating this week. Hot - rolled coils had both supply and demand decreasing, and inventory accumulation was significant. Currently, the inventory of both rebar and hot - rolled coils is rising, but the demand is insufficient [3]. Iron Ore - Prices and Positions: The main contract (I2601) of iron ore closed at 789.00 yuan/ton, up 2.00% (+15.50), with an increase of 37210 lots in position to 39.27 million lots. The weighted position was 92.48 million lots. The spot price of PB powder at Qingdao Port was 778 yuan/wet ton, with a basis of 37.83 yuan/ton and a basis rate of 4.58% [5]. - Fundamentals: The latest shipment and arrival volume of overseas iron ore both decreased. The daily average pig iron output decreased slightly due to blast furnace maintenance. The port inventory fluctuated slightly, and the steel mill's imported ore inventory increased slightly. The overall demand was slightly weak, but there was still demand support [6]. Manganese Silicon and Ferrosilicon - Prices: On August 11, the main contract of manganese silicon (SM509) rebounded, closing up 0.89% at 6100 yuan/ton. The main contract of ferrosilicon (SF509) closed up 1.00% at 5830 yuan/ton [8]. - Analysis and Suggestions: The market is affected by sentiment, and prices fluctuate greatly. It is not recommended for speculative funds to participate excessively in the short term. Hedging funds can seize hedging opportunities according to their own situations. The over - capacity pattern of manganese silicon remains unchanged, and there is a risk of weakening demand in the future [9][10][11]. Industrial Silicon and Polycrystalline Silicon - Industrial Silicon - Prices and Positions: The main contract (SI2511) of industrial silicon closed at 9000 yuan/ton, up 3.33% (+290), with an increase of 15809 lots in weighted position to 549604 lots. The spot price of 553 in East China increased by 100 yuan/ton, and the basis of the main contract was 200 yuan/ton; the 421 price increased by 50 yuan/ton, and the basis was - 50 yuan/ton [13]. - Fundamentals: The problems of over - capacity, high inventory, and insufficient demand remain. The production rate is expected to increase in August, and the demand can provide some support, but new inventory pressure may occur. It is expected that the price will fluctuate weakly [14]. - Polycrystalline Silicon - Prices and Positions: The main contract (PS2511) of polycrystalline silicon closed at 52985 yuan/ton, up 4.32% (+2195), with a decrease of 23165 lots in weighted position to 337163 lots. The spot price remained flat, and the basis of the main contract was - 5985 yuan/ton [15]. - Fundamentals: It is expected to increase production in August, and the downstream silicon wafer production also increases, but the silicon material is likely to accumulate inventory. The price is expected to fluctuate widely, and it is recommended to participate cautiously [16]. Glass and Soda Ash - Glass - Prices and Inventory: The spot price in Shahe decreased by 4 yuan, and in Central China by 30 yuan. As of August 7, the total inventory of national float glass sample enterprises was 61.847 million weight - boxes, up 3.95% month - on - month and down 8.18% year - on - year. It is expected to fluctuate in the short term and follow the macro - sentiment in the long term [18]. - Soda Ash - Prices and Inventory: The spot price was stable, and the total inventory of domestic soda ash manufacturers was 1.8762 million tons as of August 11, up 0.60% from last Thursday. The supply increased, and the demand was weak. It is expected to fluctuate in the short term, and there are still supply - demand contradictions in the long term [19].
