1. Report Industry Investment Rating No information provided in the report regarding the industry investment rating. 2. Core Viewpoints - The overall demand for steel products is weak, with the inventory accumulation rate accelerating, and the steel mills' profit is gradually shrinking. If the demand fails to improve effectively, the price may continue to decline. Attention should be paid to the potential impact of safety inspections and environmental protection restrictions [3]. - For iron ore, although the supply pressure is not significant during the traditional shipping off - season, the contradiction between high hot metal production and weak terminal demand needs attention. The price is expected to fluctuate strongly in the short term [6]. - For ferrous alloys, the prices are affected by emotions in the short term. It is not recommended for speculative funds to participate excessively. Hedging funds can seize opportunities according to their own situations. The fundamental problems of over - supply in manganese silicon and silicon iron still exist [10][11]. - For industrial silicon and polysilicon, industrial silicon is expected to fluctuate strongly, and polysilicon will maintain a pattern of "weak reality, strong expectation" and high - volatility operation [16][17]. - For glass and soda ash, glass is expected to fluctuate weakly in the short term, and soda ash is expected to fluctuate. In the long term, the price center of soda ash may gradually rise, but the upward space is limited [19][20]. 3.

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - In the medium to long term, speculative demand has significantly declined due to market sentiment. Although some steel mills have received oral production - restriction notices, the supply of rebar is expected to be less affected. Rebar demand will be significantly suppressed, and short - term prices are under pressure. Iron ore demand has some resilience, but supply is growing faster than demand, so there is a risk of correction. The supply - demand fundamentals of float glass and soda ash are weakening [64][68]. - In the short term, the main contracts of the black series are oscillating weakly. It is recommended to conduct band trading. The main contracts of glass and soda ash lack upward drivers in the short term and are waiting for the start of the demand side [65][69]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The prices of coking coal and coke are fluctuating as the price increase has not been implemented yet; glass and soda ash prices are oscillating within a narrow range due to supply disturbances; ferrosilicon and silicomanganese prices are also fluctuating with the intertwining of long - short games [1][3] - Glass is expected to be weak and oscillating, and soda ash is also expected to be weak and oscillating; silicomanganese and ferrosilicon are expected to oscillate [2][4] 3. Summary by Related Catalogs Glass and Soda Ash Market Analysis - Glass: The glass futures market oscillated within a narrow range. The spot market was mainly for rigid - demand procurement, and the speculative sentiment weakened. This week, the开工 rate of float glass enterprises was 75.34%, unchanged from the previous week, and the manufacturer's inventory was 63.606 million heavy boxes, a 0.28% increase from the previous week [1] - Soda Ash: The soda ash futures market oscillated weakly. The downstream spot market was mainly for rigid - demand replenishment. This week, the capacity utilization rate of soda ash was 88.48%, a 1.15% increase from the previous week; the output was 771,400 tons, a 1.32% increase from the previous week; and the inventory was 1.9108 million tons, a 0.9% increase from the previous week [1] Supply - Demand and Logic - Glass: The supply - demand contradiction of glass is still large. With the previous price increase, the glass output increased significantly, and the pressure to reduce high inventory is great. The premium of the futures market has been quickly repaired. In the later stage, attention should be paid to the impact of macro - policies on the supply and demand sides of glass [1] - Soda Ash: With the implementation of new production capacity in the later stage and the lack of expectation of a significant increase in soda ash consumption, the supply - demand imbalance of soda ash will continue to intensify. Therefore, it is still necessary to restrict the release of production capacity and output through losses. In the later stage, attention should be paid to the impact of changes in the supply side such as the progress of new production capacity commissioning [1] Strategy - Glass: Weak and oscillating [2] - Soda Ash: Weak and oscillating [2] Silicomanganese and Ferrosilicon Market Analysis - Silicomanganese: The long - short game sentiment in the silicomanganese futures market continued, and the market oscillated within a narrow range. The spot market quotation did not change significantly. The price of silicomanganese 6517 in the northern market was 5,700 - 5,750 yuan/ton, and in the southern market was about 5,750 - 5,800 yuan/ton [3] - Ferrosilicon: The ferrosilicon futures market oscillated within a narrow range, with a 0.28% increase. In the spot market, the market sentiment was average, and the spot price was slightly adjusted. The ex - factory price of 72 - grade ferrosilicon natural lump in the main production area was 5,300 - 5,400 yuan/ton, and the price of 75 - grade ferrosilicon was 5,800 - 5,950 yuan/ton [3] Supply - Demand and Logic - Silicomanganese: The output of silicomanganese increased month - on - month, and the inventory continued to decline, being at the median level in the same period in recent years. With the slight increase in the manganese ore quotation, the cost of silicomanganese increased. The market still shows an oversupply situation, and it is necessary to suppress the output release through a certain degree of losses. In the later stage, attention should be paid to the cost support and shipping situation of manganese ore [3] - Ferrosilicon: With the profit repair, the output of ferrosilicon increased rapidly, the demand decreased slightly week - on - week, and the inventory continued to decline. In the long run, the ferrosilicon production capacity is relatively loose. In the later stage, attention should be paid to the cost support and the impact of industrial policies on the black sector [3] Strategy - Silicomanganese: Oscillating [4] - Ferrosilicon: Oscillating [4]

Report Summary 1. Industry Investment Rating No industry investment rating 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 continued to decline in a volatile manner. The demand for finished steel products is weak, the profits of steel mills are gradually shrinking, and the weakness of the futures market is 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 product end, and attention should be paid to the potential impact of safety inspections and environmental protection production restrictions [4]. - The prices of iron ore, manganese - silicon, and silicon - iron are affected by supply, demand, and policy sentiment. The short - term prices of iron ore may continue to adjust, and for manganese - silicon and silicon - iron, it is recommended that speculative funds wait and see, while hedging funds can seize hedging opportunities according to their own situations [7][10][11]. - The prices of industrial silicon are expected to fluctuate weakly, and the prices of polysilicon are expected to fluctuate widely. The prices of glass are expected to fluctuate weakly in the short term and follow macro - sentiment fluctuations in the long term. The prices of soda ash are expected to fluctuate in the short term and the price center may gradually rise in the long term, but the upward space is limited [16][17][19][20]. 3.
