1. Report Industry Investment Ratings No information is provided in the documents regarding industry investment ratings. 2. Core Views Glass and Soda Ash - The glass and soda ash futures markets continued to weaken yesterday. The soda ash market has an oversupply problem, and the inventory has transferred to the mid - downstream. There is no significant increase in downstream demand in the medium term. It is recommended to hold short positions. The glass spot market trading has become dull, and the industry needs capacity clearance to solve the oversupply problem. Track policies and the inventory - building performance of mid - downstream enterprises during the "Golden September and Silver October" [1]. Natural Rubber - Future supply increase expectations have weakened raw material prices, and the cost support has changed from strong to weak. The downstream tire factory's pre - holiday inventory replenishment is basically completed, and the de - stocking rhythm of natural rubber spot inventory has slowed down. Some enterprises may control production flexibly. Pay attention to the impact of typhoon weather on domestic production areas, and the 01 contract range is 15,000 - 16,500. Follow the raw material output in the main production areas during the peak season [3]. Logs - The log futures market fluctuated and closed flat. The inventory has decreased significantly, the demand has declined, and the supply is expected to increase. The market is in a volatile pattern. As the "Golden September and Silver October" approaches, pay attention to whether the shipment volume improves significantly during the seasonal peak season. It is recommended to go long at low prices [5]. Polysilicon - The polysilicon market continued to decline. Substantial support policies have not been implemented, and the industry's over - capacity pattern remains unchanged. The downstream component inventory is high, and prices are loosening. Follow national policies, the actual production start - up rate of polysilicon enterprises, and the inventory digestion progress of downstream photovoltaic component factories [6]. Industrial Silicon - From September to October, the supply of industrial silicon is increasing, and the market balance is gradually turning to looseness. The expected supply surplus is more obvious in October and narrows in November. The cost increase in the dry season in the southwest has boosted market sentiment. In the short term, the upward driving force of industrial silicon is insufficient, and the price may fluctuate between 8,000 - 9,500 yuan/ton. Pay attention to the production reduction rhythm of silicon material enterprises and industrial silicon enterprises in Sichuan and Yunnan in the fourth quarter [7]. 3.
