Report Industry Investment Rating No relevant information provided. Core Views - The core contradictions affecting the glass and soda ash markets include potential glass production line cold repairs before the Spring Festival, cost - based pricing for soda ash with new capacity on the way, and high inventories in the glass mid - stream and an ongoing capacity expansion cycle for soda ash [1]. - The glass market has a weak spot price due to high mid - stream inventories and the off - season. The soda ash market is affected by new capacity expectations and high inventories, but its upstream inventory reduction is better than expected [2]. - Glass and soda ash markets are in a state of oscillation without clear trends, and observation is recommended [7]. Summary by Directory 1. Core Contradictions and Strategy Suggestions 1.1 Core Contradictions - Before the Spring Festival, some glass production line cold repairs are yet to be realized, which impacts long - term pricing and market expectations. Policy - related supply disturbances cannot be excluded [1]. - Soda ash is mainly priced by cost. Despite occasional supply cuts, new capacity is pending, and production remains at a medium - high level. Its valuation lacks upward potential without a trend of production reduction, and its demand is expected to decline with potential glass cold repairs [1]. - In reality, the high mid - stream glass inventories need to be digested. For soda ash, the capacity expansion cycle continues, and an oversupply situation is expected [1]. 1.2 Trading - Type Strategy Suggestions - Glass spot is weak, with cold repair expectations and high mid - stream inventories. Cost and supply expectations affect long - term pricing. The 05 contract is more about expectations. The glass and soda ash markets lack clear trends and are oscillating, so observation is recommended [7]. 1.3 Basic Data Overview - Glass spot prices: Some prices decreased slightly on January 5, 2026. For example, the average price of沙河交割品 dropped by 1 yuan compared to the previous day [11]. - Glass futures prices: The 05, 09, and 01 contracts all decreased on January 5, 2026, with the 09 contract having the largest decline rate of - 0.67% [11]. - Soda ash spot prices: Most regional prices remained stable on January 5, 2026, except for a 20 - yuan decrease in the light soda ash price in the central China region [13]. - Soda ash futures prices: The 05, 09, and 01 contracts all decreased on January 5, 2026, with the 05 contract having the largest decline rate of - 2.65% [14]. 2. This Week's Important Information and Next Week's Attention Events 2.1 This Week's Important Information - Positive information: Some glass production line cold repairs are expected to be realized before the Spring Festival, and the National Development and Reform Commission will control high - energy - consuming and high - emission projects starting from 2026, which may lead to supply - side policy expectations [14]. - Negative information: New soda ash capacity is expected to increase, and the renewed glass cold repair expectations will affect soda ash demand [15]. 2.2 Next Week's Important Events to Watch - Whether there are further clear instructions on industrial policies. - Glass production and sales, spot prices, and soda ash spot transaction situations [19]. 3. Disk Interpretation - Unilateral trends and capital movements: The glass 05 contract has unclear expectations, with weak supply and demand and no clear signals. Near - term spot pressure is high, and mid - stream inventories are high. Long - term supply reduction and cost increase are expected, but demand is unclear [20]. - Basis and spread structure: The glass 5 - 9 spread oscillates without a clear direction. The soda ash market maintains a C - structure, and its long - term situation may worsen with new capacity [25][26]. 4. Valuation and Profit Analysis 4.1 Industry Chain Up - and Downstream Profit Tracking - Glass: Natural gas production lines are in the red, while petroleum coke and coal - gas production lines have small profits [42]. - Soda ash: The cash cost of the ammonia - soda process in Shandong is around 1210 yuan/ton, and that of the combined - soda process in central China is around 1105 yuan/ton [43]. 4.2 Import and Export Analysis - Glass: The monthly average net export of float glass is 6 - 7 tons, accounting for 1.4% of the apparent demand, with limited impact [50]. - Soda ash: The monthly average net export of soda ash is 18 - 21 tons, meeting expectations and accounting for 5.8% of the apparent demand, with a significantly higher proportion than last year. The November export was close to 19 tons, maintaining high export expectations [50]. 5. Supply, Demand, and Inventory 5.1 Supply - Side and Projections - Glass supply: The daily melting volume of glass has dropped to around 15.1 - 15.2 tons. Some cold repair production lines are yet to be realized before the Spring Festival, and the daily melting volume is expected to decline further [56]. - Soda ash supply: The current daily production of soda ash fluctuates slightly around 10.5 - 10.7 tons. The first phase (100 tons) of the Alxa Phase II project has started trial production, and the 70 - ton new capacity of Yingcheng Xindu is pending [59]. 5.2 Demand - Side and Projections - Glass demand: Mid - stream glass inventories remain high, and spot pressure exists. As of the end of December, glass deep - processing orders and raw material inventories decreased both month - on - month and year - on - year. The cumulative apparent demand for glass in 2025 is estimated to decline by 7.5%. Terminal demand is weak, and downstream restocking during the off - season is limited [62]. - Soda ash demand: The combined daily melting volume of float glass and photovoltaic glass is 24 tons, showing a slight decline. The daily demand for soda ash is about 4.8 tons. With potential glass cold repairs, soda ash demand is expected to decline. Photovoltaic glass inventories are accumulating, and its cold repair expectations should be monitored. The cumulative apparent demand for soda ash in 2025 is estimated to decline by 0.2% [73][74]. 5.3 Inventory Analysis - Glass: According to Longzhong data, the total glass factory inventory is 56.866 million weight - cases, a month - on - month decrease of 1.757 million weight - cases (- 3.00%) and a year - on - year increase of 28.96%.

Report Industry Investment Rating - The investment rating for the glass industry is "Oscillating with a Bullish Bias" [2][91] Core Viewpoints of the Report - The glass futures strengthened last week, with the weekly line closing as a medium阳线. The cold - repair of multiple production lines at the end of the month, combined with Hubei's environmental protection rectification and gas - conversion plan, drove up the market due to positive supply - side expectations. Considering the supply - side pressure of soda ash and the expected contraction of float glass factory capacity, there is an opportunity to go long on glass and short on soda ash. After the New Year's Day, there are still expectations of some production lines shutting down, and the pre - Spring Festival restocking by spot - futures traders will boost production and sales. Technically, the bullish force is dominant, so the glass price is expected to maintain a short - term bullish trend [2][91] Summary According to the Table of Contents 1. Market Review: Rebound in the Market and Narrowing of the Basis - **Futures Price**: The glass 05 contract closed at 1,087 yuan/ton last week, up 39 yuan from the previous week.

The retail volume of new - energy passenger vehicles was 1.321 million, with a penetration rate of 59.3% [44] - **Real Estate Demand**: In November, China's real estate completion area was 45.9293 million square meters, a year - on - year decrease of 25%; the new construction area was 43.9531 million square meters (-28%); the construction area was 31.2717 million square meters (-42%); the commercial housing sales area was 67.1974 million square meters (-18%). From December 22 to 28, the total commercial housing transaction area in 30 large - and medium - sized cities was 3.44 million square meters, a month - on - month increase of 35% and a year - on - year decrease of 23%. The real estate development investment in November was 502.82 billion yuan, a year - on - year decrease of 31% [49] - **Import and Export**: In November, China imported 310,900 weight boxes of float glass (a year - on - year increase of 27%) and exported 1.69 million weight boxes (a year - on - year increase of 47%) [51] - **Soda Ash - Cost Side**: The spot prices of heavy soda ash were 1,325 yuan/ton (0) in North China, 1,250 yuan/ton (0) in East China, 1,300 yuan/ton (0) in Central China, and 1,450 yuan/ton (0) in South China. The soda ash 05 contract closed at 1,209 yuan/ton (+25), and the basis of soda ash in Central China 05 was 91 yuan/ton (-25) last Friday. The ammonia - soda process cost of soda ash enterprises was 1,312 yuan/ton (-7), with a gross profit of -57 yuan/ton (+9); the co - production process cost was 1,738 yuan/ton (-29), with a gross profit of -21 yuan/ton (+21). As of December 31, the national factory - level inventory of soda ash was 1.4083 million tons (a month - on - month decrease of 30,200 tons), including 676,100 tons of heavy soda ash (a month - on - month decrease of 26,900 tons) and 732,200 tons of light soda ash (a month - on - month decrease of 3,300 tons). The apparent consumption of heavy soda ash last week was 454,300 tons, a week - on - week increase of 45,200 tons; the apparent consumption of light soda ash was 318,400 tons, a week - on - week increase of 11,100 tons. The production - sales ratio of soda ash was 108.54%, a week - on - week increase of 9.23% [58][60][79][88] 3. Investment Strategy: Short - Term Speculation, Oscillating with a Bullish Bias - **Main Logic**: The glass futures strengthened last week. The cold - repair of multiple production lines at the end of the month, combined with Hubei's environmental protection rectification and gas - conversion plan, drove up the market due to positive supply - side expectations. The supply decreased as 3 production lines shut down last week, with the daily melting volume decreasing by nearly 150,000 tons. The demand in the northern market decreased as terminal projects were coming to an end, and the end - of - year demand in the southern market was lower than last year, with poor restocking willingness among middle - and lower - stream enterprises. Most manufacturers focused on collecting payments and were bearish on the market next year. Given the supply - side pressure of soda ash and the expected contraction of float glass factory capacity, there is an opportunity to go long on glass and short on soda ash. After the New Year's Day, there are still expectations of some production lines shutting down, and the pre - Spring Festival restocking by spot - futures traders will boost production and sales. Technically, the bullish force is dominant [2][91] - **Operation Strategy**: Oscillating with a Bullish Bias [2][91]

1. Report Industry Investment Rating - Not provided in the given content. 2. Core View of the Report - The glass fundamentals are weak, and it is expected to fluctuate weakly in the short term. The production profit of glass has limited recovery, cold - repairs have increased leading to further supply contraction, downstream deep - processing orders are weak due to the real estate drag, and the inventory is at a historically high level for the same period [2]. 3. Summary by Relevant Catalog 3.1 Glass Futures Market - The closing price of the main glass futures contract is 1087 yuan/ton, the spot price of Shahe Safety large - plate glass is 904 yuan/ton, and the main basis is - 183 yuan/ton, with a 0.00% change compared to the previous value [6]. 3.2 Glass Spot Market - The market price of 5mm white glass large - plate in the spot benchmark area of Hebei Shahe is 904 yuan/ton, which is flat compared to the previous day [12]. 3.3 Fundamental Analysis - Cost Side - The production profit of glass has limited recovery, and there is an expectation of further cold - repairs in the industry due to low production profit [2][4]. 3.4 Fundamental Analysis - Supply - The number of operating national float glass production lines is 218, with an operating rate of 73.89%, and the number of operating production lines is at a historically low level for the same period.
