Group 1 - The core viewpoint is that Fujian has become a significant player in the global automotive glass market, producing one out of every three automotive glasses worldwide, with a particular focus on innovative products like the "5G antenna glass" which has received over 4 million orders this year [1][3][8] - The "5G antenna glass" not only supports high-speed data transmission exceeding 70 Mbps but also features multiple functionalities such as infrared isolation, adjustable light transmission through liquid crystal arrangement, and self-heating for defrosting [3][5] - The development of new technologies and production processes is being driven by an increasing number of companies in Fujian establishing dedicated R&D laboratories, which facilitate the continuous emergence of innovative products like the "5G antenna glass" [7][8] Group 2 - The testing of automotive glass, particularly the windshield, emphasizes that the glass should break within a fraction of a second upon impact to absorb energy, while also ensuring that the shattered glass does not pose a secondary injury risk [5] - The support from various government departments during the "14th Five-Year Plan" period has been crucial, with policies such as expanding the scope of "technology loans" to promote R&D investment and innovation, enhancing the reputation of "Fujian manufacturing" [8]

1. Report Industry Investment Rating No relevant content provided. 2. Report's Core View Glass - Supply: Current daily melting is around 160,000 tons with a short - term upward expectation. Xinjiang Puyao and Zhuzhou Liling Qibin restarted production in August. Attention should be paid to unexpected supply changes and the coal - to - gas conversion of Shahe production lines [3]. - Inventory: The total inventory of national float glass sample enterprises is 60.908 million heavy cases, a week - on - week decrease of 675,000 heavy cases (-1.10%) and a year - on - year decrease of 18.56%. The inventory days are 26 days, 0.3 days less than the previous period. Middle - stream inventories in Shahe and Hubei remain high [3]. - Profit: According to Longzhong data, the profit of natural gas - fired glass production lines is - 165 yuan, coal - gas - fired is + 94 yuan, and petroleum - coke - fired is + 41 yuan [3]. - Demand: As of mid - September, the deep - processing order days are 10.5 days, a week - on - week increase of 1.0% and a year - on - year increase of 2.94%. The deep - processing raw material reserve is 11.1 days, a week - on - week decrease of 5.1% and a year - on - year increase of 60.87%. This week's production and sales weakened overall, especially in Shahe [3]. - Strategy: High inventories in the upper and middle reaches and weak real - world demand limit price increases. There are still differences in whether there will be an unexpected reduction in supply in the fourth quarter. The glass price currently lacks a clear trend and trading logic. The near - term supply - strong and demand - weak pattern remains unchanged, and the mid - stream inventory reduction ability is weak. There are still profits in coal - gas and petroleum - coke production lines, and policy expectations are uncertain. The cumulative apparent demand from January to September is estimated to decline by 6% - 6.5%, and the spot market is in a state of weak balance to weak surplus. Future attention points include supply ignition expectations, coal prices, and mid - stream inventory reduction [3]. 纯碱 - Supply: Weekly production is 745,700 tons (a week - on - week decrease of 15,400 tons, with heavy soda down 4,000 tons and light soda down 11,400 tons). The supply remains high, and Yuanxing Phase II started the commissioning stage on September 19 [4]. - Inventory: The factory inventory is 1.7556 million tons, a week - on - week decrease of 41,900 tons. The delivery warehouse inventory is 614,900 tons (an increase of 59,400 tons). The total inventory of factory and delivery warehouses is 2.3705 million tons, a week - on - week increase of 17,500 tons. The upstream soda ash plants are reducing high - level inventories [6]. - Profit: According to Longzhong data, the theoretical profit of the dual - ton joint - alkali method is - 71 yuan/ton, and that of the ammonia - alkali method is - 37 yuan/ton. The raw salt price remained stable this week, while the coal price increased, leading to a slight increase in the cost [6]. - Demand: The inventory of photovoltaic finished products continues to decline, and the pressure eases. The daily melting of photovoltaic glass is 88,800 tons, remaining stable. The float glass end is generally stable. In August, the export of soda ash was 215,400 tons, far exceeding expectations, a month - on - month increase of 33.6% [6]. - Strategy: Market sentiment and focus will fluctuate, increasing the volatility of soda ash. With Yuanxing Phase II starting commissioning, the long - term supply pressure of soda ash persists. The mid - and downstream of heavy and light soda ash mainly replenish inventory due to rigid demand, and the pressure on soda ash plants has eased. The long - and medium - term supply of soda ash is expected to remain high, and normal maintenance continues. The fundamentals of photovoltaic glass have further improved, and the inventory of photovoltaic glass finished products has declined to a relatively low level. The rigid demand for soda ash is stable, and there is no expectation of weakening. The balance of heavy soda ash remains in surplus. However, the export of soda ash in August exceeded 200,000 tons, which alleviates domestic pressure to some extent. High inventories in the upper and middle reaches limit the price of soda ash, and the supply - strong and demand - weak pattern remains unchanged [6]. 3.

Report on Glass 1. Investment Rating No investment rating information is provided in the report. 2. Core View The market sentiment showed a trend of first declining and then rising during the week. Driven by the strengthening of futures, local trading improved slightly. However, the overall terminal demand remained weak, with downstream procurement being cautious and a strong wait - and - see sentiment. On the supply side, there were limited adjustments to production lines, and the market supply was relatively abundant. Enterprises mostly maintained stable prices for shipments, with actual transactions flexibly adjusted. Regional inventory performance was significantly differentiated, with better destocking effects in East, Central, South, and Northwest China, while North and Southwest China still faced certain inventory accumulation pressure. Fundamentally, the market lacked unilateral driving factors, and the price fluctuation range was limited. From a trading perspective, the trading volume and open interest decreased this week, and the willingness of funds to enter the market was not strong, but the price center continued to rise. As the "Golden September and Silver October" period approaches, the trading volume is expected to form support at low levels, and it is advisable to try long positions at low levels with a light position [14]. 3.

Report on Soda Ash 1. Investment Rating No investment rating information is provided in the report. 2. Core View On the supply side, it was generally stable. Some plants such as Anhui Hongsifang and Hubei Xindu resumed production one after another, but short - term local shutdowns for maintenance still led to a slight contraction in the industry's operating load, and the overall supply showed narrow - range fluctuations. Downstream demand was mainly for rigid procurement. The pre - holiday stocking willingness of some enterprises gradually increased, and they replenished inventory in moderation at low prices, driving the enterprise inventory to show a downward trend. Some manufacturers' orders were basically fully signed, and the mentality of stabilizing prices was strengthened. However, the current industry supply was still at a relatively high level, and the absolute inventory level was still relatively high, so the upward driving force of the fundamentals was still limited. From a trading perspective, the trading volume this week was small, and an effective breakthrough could not be formed. The form was relatively loose, and it was still in a volatile market. It was recommended to be cautious [63]. 3. Summary by Directory 01.

Report 1: Glass and Soda Ash Futures and Spot Daily Report 1. Report Industry Investment Rating Not provided in the report. 2. Core Viewpoints - **Soda Ash**: The supply - demand pattern remains bearish. After the traditional summer maintenance season, supply is at a high level. Without actual capacity exit or load - reduction, inventory will face further pressure.
