1. Report Industry Investment Rating - Not mentioned in the provided content 2. Core View of the Report - On September 1st, industrial silicon fluctuated strongly. The main contract 2511 closed at 8,495 yuan/ton, with an intraday increase of 0.89%, and the position decreased by 6,966 lots to 285,000 lots. The reference price of Baichuan industrial silicon spot was 9,364 yuan/ton, down 7 yuan/ton from the previous trading day. The price of the lowest deliverable 421 product rebounded to 8,600 yuan/ton, and the spot premium expanded to 290 yuan/ton. Polysilicon fluctuated weakly. The main contract 2511 closed at 52,285 yuan/ton, with an intraday increase of 6.03%, and the position increased by 5,412 lots to 150,400 lots. The price of N-type recycled polysilicon materials rose to 49,000 yuan/ton, and the price of the lowest deliverable silicon materials fell to 49,000 yuan/ton, and the spot discount expanded to 1,500 yuan/ton. The resumption of production in the north and south of industrial silicon and the increase in crystalline silicon have become marginal drivers, and the overall operating center is expected to rise slightly. After the previous anti-involution news was fully priced in, the trading center of polysilicon gradually shifted to the fundamental logic. Due to the limitation of the terminal power station yield, the acceptance of price increases in the component link has reached its peak, and the silicon materials have cooled down following the downstream market sentiment. Before the introduction of specific policy measures, the market is still in the game between policy support and fundamental drag. Polysilicon has entered a range mode with obvious top and bottom, and policy dynamics have a phased disturbing effect on the market. Pay attention to the results of the energy-saving special supervision of the Ministry of Industry and Information Technology on September 30th and the inventory clearance situation of the industrial chain, and still be vigilant against the risks of delayed capacity storage and weak peak season [2] 3. Summary by Relevant Catalogs 3.1 Research View - Industrial silicon fluctuated strongly on September 1st, with an intraday increase of 0.89%, and the position decreased. The spot price decreased slightly, and the spot premium expanded. Polysilicon fluctuated weakly, with an intraday increase of 6.03%, and the position increased. The price of N-type recycled polysilicon materials rose, and the price of the lowest deliverable silicon materials fell, and the spot discount expanded. The resumption of production in the north and south of industrial silicon and the increase in crystalline silicon are the marginal drivers, and the overall operating center is expected to rise slightly. The trading center of polysilicon has shifted to the fundamental logic, and the market is in the game between policy support and fundamental drag. Pay attention to the policy results and inventory clearance situation [2] 3.2 Daily Data Monitoring - **Industrial Silicon**: The futures settlement prices of the main and near-month contracts decreased.
