Report Summary 1. Investment Rating The report does not provide an industry investment rating. 2. Core Views - 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 restored, steel prices may not be able to maintain the current level, and the futures prices may gradually return to the supply - demand logic [3]. - For iron ore, although the current supply - side pressure is not significant, attention should be paid to the subsequent shipping progress. If the terminal demand continues to weaken, the short - term iron ore price may be slightly adjusted [6]. - For ferrosilicon and manganese silicon, in the short - term disordered market environment affected by emotions, it is not recommended for speculative funds to participate excessively. Hedging funds can seize hedging opportunities according to their own situations [8]. - For industrial silicon, it is expected to run weakly with fluctuations, and for polysilicon, it is expected to have wide - range fluctuations [14][16]. - For glass and soda ash, they are expected to fluctuate in the short term. In the long term, glass prices follow macro - emotions, and soda ash prices are affected by supply - side and market sentiment under the "anti - involution" logic [18][19]. 3.
