1. Report Industry Investment Rating - No specific industry investment rating is provided in the report. 2. Core View of the Report - The polysilicon market is still under fundamental sentiment suppression but remains stable overall. The new energy - consumption national standard may affect the supply pattern in the short - term, and the uncertainty of the "anti - involution" policy is an important factor in market fluctuations. New capacity faces difficulties in being launched in the short - term. On the demand side, silicon wafer prices are flat, downstream inventory is high, new orders slow down, and domestic PV installation has declined for two consecutive months, resulting in weak terminal demand. However, the growth in N - type material demand may offset some of the P - type surplus and support prices. It is recommended to buy on dips and observe whether downstream PV enterprises can effectively transfer costs after the holiday [2]. 3.
