Core Viewpoint - The domestic futures market for the chemical industry showed a mostly positive trend, with soda ash futures experiencing a slight increase in price, indicating a stable yet cautious market outlook for the sector [1] Supply - Last week, some production lines reduced output, with Jiangsu Debang and Ningxia Risheng undergoing maintenance, and a planned maintenance for Zhongyan Kunshan in December. Overall, soda ash production decreased by 10,800 tons week-on-week [1] Demand - Downstream demand for soda ash remains weak, primarily driven by essential purchasing needs, with moderate low-price stock replenishment. The production capacity for float glass and photovoltaic glass slightly declined, indicating limited fluctuations in overall essential consumption [1] Inventory - As of November 10, 2025, total inventory of soda ash in domestic manufacturers was 1.7062 million tons, a decrease of 800 tons from the previous week, representing a decline of 0.47%. Light soda ash inventory was 797,700 tons, down by 1,690 tons, while heavy soda ash inventory was 908,500 tons, up by 890 tons [1] Market Outlook - The market is expected to see narrow upward movement in soda ash prices, with light soda ash prices slightly increasing. Supply is expected to remain high, and inventory levels are likely to continue at elevated levels. The production capacity for photovoltaic glass is stable, while four production lines for float glass have recently been shut down, leading to reduced demand for heavy soda ash. Attention is drawn to the potential continuation of price increases for light soda ash and the willingness of downstream sectors to replenish stocks, with expectations that soda ash prices are unlikely to drop in the short term [1]

1. Report Industry Investment Rating - The investment strategy for the glass industry is to expect a weak and volatile trend [3]. 2. Core View of the Report - The glass futures market showed a pattern of rising first and then falling last week, with the weekly line closing as a doji with an upper shadow. The short - term technical signals were favorable during the week but were suppressed by the fundamental reality. With the implementation of the production line shutdown plan, the futures price fluctuated within a narrow range. In the future, there is no strong positive expectation in the short and medium - term. The replenishment sentiment of the mid - and downstream is low at the end of the year, and the demand may continue to weaken. Considering the relatively high inventory and the delivery pressure in the near - month contracts, it is recommended to hold out - of - the - money call options on the glass 01 contract until expiration or look for short - selling opportunities when the 01 contract briefly rallies, with a reference range of 1140 - 1150 [3]. 3. Summary by Relevant Catalogs 3.1 Investment Strategy - The main logic is that the glass futures price was affected by the production line shutdown and fundamental suppression last week. In the future, due to weak demand and high inventory, the market is expected to be weak and volatile. The recommended operations are to hold out - of - the - money call options on the glass 01 contract until expiration or short - sell on rallies [3]. 3.2 Market Review - Price - **Spot price**: As of November 7, the market price of 5mm float glass was 1300 yuan/ton (unchanged) in North China, 1140 yuan/ton (+20) in Central China, and 1240 yuan/ton (-10) in East China. - **Futures price**: Last Friday, the glass 01 contract closed at 1091 yuan/ton, up 8 yuan for the week [11]. 3.3 Market Review - Spread - **Soda - glass spread**: As of November 7, the soda futures price was 1210 yuan, the glass futures price was 1091 yuan, and the spread between them was 119 yuan/ton (-23). - **Basis**: Last Friday, the basis of the glass 01 contract was 49 yuan/ton (+62). - **Contract spread**: Last Friday, the 01 - 05 spread was - 134 yuan/ton (+15) [12][17]. 3.4 Profit - **Natural gas process**: The cost was 1574 yuan/ton (-2), and the gross profit was - 334 yuan/ton (-8). - **Coal - gas process**: The cost was 1211 yuan/ton (+24), and the gross profit was - 81 yuan/ton (-24). - **Petroleum coke process**: The cost was 1092 yuan/ton (+2), and the gross profit was 48 yuan/ton (+18). - **Fuel prices**: On November 7, the industrial natural gas price in Hebei was 3.8 yuan/m³, the CIF price of US 3% sulfur shot coke was 170 US dollars/ton, and the price of Yulin thermal coal was 672 yuan/ton [20]. 3.5 Supply - Last Friday, the daily melting volume of glass was 157,505 tons/day (-2650), with 222 production lines in operation.
