1. Report Industry Investment Rating No information provided in the content. 2. Core Views of the Report - On May 12, polysilicon showed a volatile and slightly stronger trend, with the main 2506 contract closing at 38,450 yuan/ton, an intraday increase of 2.49%, and the position increasing by 248 lots to 67,504 lots. Industrial silicon also showed a volatile and slightly stronger trend, with the main 2506 contract closing at 8,320 yuan/ton, an intraday increase of 0.24%, and the position decreasing by 1,216 lots to 16,900 lots [2]. - There was a small amount of seasonal production increase in the Southwest, and the production reduction progress in the Northwest was slow. The industry inventory was still accumulating. At the current low position of the futures price, it was difficult for enterprises to conduct hedging, and industrial silicon continued to be in a state where it was easier to fall than to rise [2]. - The industry would hold another meeting on self - restricted production and price support for polysilicon, and the release rhythm of planned new production capacity might be postponed. As the delivery period approached, the ratio of virtual to real warehouse receipts for polysilicon was too high, giving room for long - position players to compete. It was necessary to track the meeting results and the movement of warehouse receipts and be vigilant against abnormal risks before the delivery month [2]. 3. Summary by Relevant Catalogs 3.1 Research Views - Polysilicon and industrial silicon futures prices both showed a volatile and slightly stronger trend on May 12.
