Core Views Industrial Silicon - In the second half of the year, the industrial silicon industry is in a cycle of accelerating the clearance of backward production capacity and entering the destocking process. The supply pressure will be continuously released with the implementation of production plans in Southwest China during the wet season. The overall support from the downstream demand side is expected to strengthen, but the demand may be suppressed if the integration of the photovoltaic industry makes substantial progress. The inventory is expected to further decline with the improvement of demand. Overall, the price of industrial silicon will show a wide - range oscillation in the second half of the year. The strategy is to pay attention to the opportunity of laying out long positions in industrial silicon on dips [4]. - The positive factors include the positive signal from the "anti - involution" policy, limited further downward space for costs in the short term, and better - than - expected demand. The negative factors are the release of production capacity in Southwest China during the wet season and the potential weakening of demand due to the integration of downstream polysilicon enterprises [7][8]. Polysilicon - In the second half of the year, the polysilicon market is in a stage where the fundamental logic and the "anti - involution" logic alternate. From the fundamental perspective, the expectation of lower electricity prices and increased profits may prompt enterprises to increase production capacity, while the demand growth is limited, and the high - inventory pressure persists. From the "anti - involution" logic, effective integration agreements or coordinated production - reduction measures may reverse the current situation. The strategy is to pay attention to the positive spread opportunity between PS2509 and PS2512. - The positive factors are the potential industry - wide capacity integration and the external demand stimulus from the US "big and beautiful" bill. The negative factor is the potential inventory accumulation if the integration plan fails to materialize [10].
