1. Report Industry Investment Rating There is no information provided regarding the report industry investment rating in the given content. 2. Core Viewpoints of the Report - The overall atmosphere in the commodity market was weak yesterday, and the prices of finished steel products showed a weak and fluctuating trend. If the subsequent demand cannot be effectively restored, steel prices may not maintain their current levels, and the futures prices may gradually return to the supply - demand logic [3]. - For iron ore, although the current supply pressure is not significant, the short - term upward increase in hot metal may be limited, and the futures price may adjust slightly [6]. - For ferrosilicon and manganese silicon, due to the "anti - involution" sentiment, the prices have dropped significantly. It is recommended that investment positions remain on the sidelines, while hedging positions can participate opportunistically. In the long - term, the demand for both may weaken marginally [7][8][9]. - For industrial silicon and polysilicon, industrial silicon is expected to fluctuate weakly, and polysilicon is expected to fluctuate widely [13][14]. - For glass and soda ash, both are expected to fluctuate in the short - term. In the long - term, glass prices may follow macro - sentiment, and soda ash prices are expected to have a gradually rising price center, but their upward space may be limited [16][17]. 3.

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.
