1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views - Natural Rubber: Short - term rubber prices are rebounding due to macro - sentiment and产区 rainfall. It is recommended to wait and see how raw material prices change after the weather in the main producing areas improves [1]. - Glass and Soda Ash: For soda ash, the supply - demand pattern is in excess, and inventory is accumulating. The short - term policy and news cause significant price fluctuations, so it is advisable to wait and see. For glass, the current market is affected by the summer off - season, and the fundamental demand is under pressure. It is necessary to wait for more cold - repair to bring a real turnaround, and it is also recommended to wait and see [3]. - Log: The log futures have risen sharply recently, but the current demand is in the off - season, and the follow - up supply will gradually recover. The short - term upward sustainability of the 09 contract needs to be observed, and attention should be paid to market sentiment and policy expectations [4]. - Industrial Silicon: Although the fundamentals of industrial silicon have not changed much, the futures price increase has opened the arbitrage window, driving up the spot price. The supply is expected to increase. It is recommended to try short positions and pay attention to position control and risk management [5]. - Polysilicon: The polysilicon futures have risen sharply and then fallen back. It is necessary to pay attention to whether the price increase can be transmitted downstream and whether it can be digested by terminal installations. With the approaching delivery month, attention should be paid to position control and risk management [7]. 3.
