1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - On July 29, polysilicon prices stopped falling and rebounded. The main 2509 contract closed at 50,805 yuan/ton, with an intraday increase of 3.76%. The N-type recycled polysilicon material price rose to 46,500 yuan/ton, and the price of the lowest deliverable silicon material also reached 46,500 yuan/ton. The spot discount narrowed to 4,245 yuan/ton. Industrial silicon showed a strong oscillation. The main 2509 contract closed at 9,350 yuan/ton, with an intraday increase of 2.35%. The Baichuan industrial silicon spot reference price was 9,570 yuan/ton, down 277 yuan/ton from the previous trading day. The price of the lowest deliverable 421 grade dropped to 9,250 yuan/ton, and the spot premium narrowed to 255 yuan/ton. The Ministry of Industry and Information Technology re - emphasized consolidating the comprehensive governance results against excessive competition, highlighting the governance of key industries such as photovoltaics to force out backward production capacity through standard improvement. Polysilicon was boosted by the news and regained momentum. Industrial silicon was driven up by polysilicon and showed a strong performance. Currently, policies still support the market, but after the pre - speculative demand was realized, market sentiment cooled down, and there is insufficient momentum to reach new highs. After the exchange adjusted margins and handling fees, heavy - position chasing and killing should be avoided. Attention should be paid to the inter - month reverse spread space and PS/SI ratio arbitrage, as well as the resumption of production in the southwest region and policy progress [2]. 3.
