1. Report Industry Investment Rating No relevant information provided. 2. Core View of the Report - The overall atmosphere in the commodity market is weak, with the prices of finished steel products showing a weak and volatile trend. The demand for finished products is clearly weak, the profits of steel mills are gradually shrinking, and the weak characteristics of the futures market are becoming more prominent. If the demand cannot be effectively improved in the future, the prices may continue to decline. The raw material end is more resilient than the finished products, and attention should be paid to the potential impact of safety inspections and environmental protection restrictions. It is recommended to continuously track the progress of terminal demand recovery and the support of the cost end for the prices of finished products [3]. - The price of iron ore is expected to be weak and volatile in the short term. The recent increase in overseas mine shipments may bring pressure, and the strong raw material prices continue to affect the profits of steel mills. The fundamentals of finished products are relatively weak, and the futures market shows that raw materials are stronger than finished products. The impact of production restrictions on iron water production in Tangshan steel mills needs to be observed [6]. - The prices of ferrosilicon and manganese silicon continue to be weak. The over - supply pattern of manganese silicon remains unchanged, and its price is expected to remain weak until mid - October. There is no obvious contradiction in the supply - demand fundamentals of ferrosilicon, and attention should be paid to changes in downstream terminal demand and relevant policies. Hedging funds are advised to seize hedging opportunities [9][11]. - The price of industrial silicon is expected to be weak and volatile in the short term, with the supply pressure from resuming production greater than the demand support. The price of polysilicon continues to be in a pattern of "weak reality, strong expectation", with high volatility and possible upward exploration if favorable news is released [14][15]. - The price of glass is expected to be weakly volatile in the short term, and its long - term trend depends on policy support and demand improvement. The price of soda ash is expected to be volatile in the short term, and its price center may gradually rise in the long term, but the upward space is limited due to the contradiction between supply and demand [17][18]. 3.

Report Industry Investment Rating - No relevant content provided. Core Viewpoints - As the Politburo meeting concludes and the sentiment related to "anti - involution" cools down, the market sentiment becomes rational, and the futures price trend weakens. If the subsequent demand cannot be effectively repaired, the steel price may not maintain the current level, and the futures price may gradually return to the supply - demand logic. It is recommended to continuously monitor the recovery progress of terminal actual demand and the support of the cost side for the finished product price [3]. - In the short term, the iron ore price may be slightly adjusted. Attention should be paid to whether the contradiction between high hot metal production and terminal demand will further intensify. Also, follow - up actions of blast furnace enterprises regarding the production suspension of Tangshan independent rolling enterprises need to be monitored [6]. - In the short - term market environment controlled by emotions, it is not recommended for speculative funds to participate excessively, and it is advisable to wait and see. Hedging funds can seize hedging opportunities according to their own situations but should control margin (cash flow) safety [10]. - It is expected that the industrial silicon price will fluctuate weakly, with support at 8000 yuan/ton. The polysilicon price is expected to fluctuate widely, with support levels at 47000 and 44000 yuan/ton respectively [14][16]. - In the short term, it is expected that glass and soda ash will fluctuate. In the long term, glass prices will fluctuate with macro - sentiment, and soda ash prices are expected to gradually increase in the price center, but their upward space is limited [18][19]. Summary by Category Steel - **Price and Position Data**: The closing price of the rebar main contract was 3188 yuan/ton, down 1 yuan/ton (- 0.03%) from the previous trading day.

Rebar demand decreased significantly this week, production was basically the same as last week, and the inventory accumulation speed increased. Hot - rolled coil demand recovered significantly, production was basically the same as last week, and the inventory accumulation speed slowed down. Currently, both rebar and hot - rolled coil inventories are on the rise marginally, steel mill profits are good, and production remains high, but the demand side's carrying capacity is obviously insufficient [3]. Iron Ore - **Price and Position Data**: The main iron ore contract (I2601) closed at 776.00 yuan/ton, with a change of + 0.13% (+ 1.00), and the position changed by - 4631 lots to 447,300 lots.

The main ferrosilicon contract (SF509) closed up 0.17% at 5754 yuan/ton [8]. - **Market Situation**: The market for "anti - involution" trading still disturbs the market, and relevant emotional disturbances will continue to affect the market. The over - supply situation of manganese silicon has not changed, and its production has shown an upward trend recently. It is expected that in the future, the demand for ferrosilicon, manganese silicon, or the entire black sector will likely weaken marginally [10][11]. Industrial Silicon and Polysilicon - **Price and Position Data**: The main industrial silicon contract (SI2511) closed at 8805 yuan/ton, up 1.50% (+ 130). The weighted contract position changed by - 3135 lots to 531,988 lots. The main polysilicon contract (PS2511) closed at 52740 yuan/ton, up 4.58% (+ 2310). The weighted contract position changed by + 12752 lots to 322,861 lots [13][15]. - **Market Situation**: The over - capacity, high inventory, and insufficient effective demand of industrial silicon have not fundamentally changed.
