1. Report Industry Investment Rating - Not mentioned in the report 2. Core Viewpoints of the Report - From the supply - side, Yunnan, Sichuan and other regions are gradually entering the wet season, with an advantage in electricity price costs. Last week, production increased slightly and capacity utilization began to rise, and large enterprises started to increase production during the wet season. From the demand - side, the downstream of industrial silicon is mainly concentrated in the organic silicon, polysilicon and aluminum alloy fields. The organic silicon market's spot price continues to decline, but enterprises are still increasing production during the wet season, and it is expected that production may increase slightly this week, which is partially beneficial to industrial silicon. The polysilicon sector is in a state of reduced load operation, and demand for industrial silicon has declined. In the aluminum alloy field, there is some demand support, but enterprises mainly replenish inventory as needed, with inventory increasing, prices weakening, and it is difficult to drive up demand. Overall, the total demand for industrial silicon from the three downstream industries shows a flat trend. The number of industrial silicon warehouse receipts has declined, and the large number of warehouse receipts has brought huge delivery pressure to the market. It is recommended to maintain a short - selling strategy in the medium and long - term [2] 3.
