Report Industry Investment Ratings No relevant content provided. Core Views Glass and Soda Ash - Soda ash remains in an obvious oversupply situation, with weakening spot sales recently. In the medium term, after the PV glass capacity growth slows down and the float glass capacity stabilizes, there is still pressure on supply and demand, and there may be further cold repair expectations. It is recommended to wait for a new opportunity to short. [1] - The glass market has seen a significant weakening in the recent market sentiment, and the spot sales have also declined sharply. The inventory has shifted from manufacturers to middle - men, and the overall spot price is difficult to increase further. It is recommended to hold short positions. [1] Industrial Silicon - Driven by the good atmosphere in the commodity market, industrial silicon has risen. In August, the supply and demand of the industrial silicon market both increase, and it is expected to reach a tight balance. If the price drops to 8000 - 8500 yuan/ton, it is advisable to try long positions. [2] Polysilicon - In August, the supply and demand of polysilicon both increase, but the supply growth rate is larger, and there is still pressure on inventory accumulation. If there is new progress in capacity integration or clearance, polysilicon is expected to rise again; otherwise, it may fluctuate and decline under the pressure of inventory and warehouse receipts. It is advisable to try long positions at low prices and buy put options to try short positions at high prices. [3] Natural Rubber - In the short term, the positive factors on the supply side are concentrated, and the spot inventory continues to decline. The rubber price is expected to be strong. It is recommended to short at high prices if the raw material supply in the peak - production season is smooth. [4] Logs - From a fundamental perspective, last week, due to the reduction of available goods in some specifications and the reluctance of traders to sell, the spot price was continuously raised. The demand remains strong, and the inventory has decreased significantly. The short - term futures market is expected to fluctuate strongly, and it is recommended to go long at low prices.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views Glass - Short - term short - selling should be cautious, and the market will gradually enter a weak oscillation state. The medium - term decline is not over. The previous policy proposals such as anti - involution and anti - deflation and the peak - season expectation led to a rebound, but currently, factors like weak basis, delivery, and high inventory cause the market to fall back. The large premium of the forward 01 contract means short - selling should be cautious in the short term [2]. 纯碱 - Short - term short - selling should be cautious, but the downward pressure remains. In the futures market, the previous over - crowded short positions led to a short - covering rally. The rising futures price drove spot purchases, but currently, the strengthening basis in the short - term decline is not conducive to the futures price. The 08 and 09 contracts may face large delivery pressure. If the supply remains high, the market will face significant pressure [3]. 3. Summary by Directory Glass - Supply - As of August 7, 2025, there are 296 glass production lines (200,000 tons/day) after excluding zombie lines, with 223 in operation and 73 cold - repaired. The daily output of float glass is 159,600 tons, unchanged from July 31. The daily loss of float glass on August 7 is 40,450 tons, unchanged from the previous period, and the weekly loss is 283,150 tons, a 0.63% decrease from the previous week [2]. - In 2025, the total daily melting volume of cold - repaired lines is 11,680 tons/day, the total daily melting volume of ignited lines is 12,110 tons/day, the potential new ignition lines have a total daily melting volume of 14,000 tons/day, the potential old - line复产 has a total daily melting volume of 8,130 tons, and the potential cold - repair lines have a total daily melting volume of 6,900 tons/day [6][7][8]. - The current in - production capacity is about 159,000 tons/day. The short - term production reduction space is limited, but if demand is poor in the third quarter, there may be a certain - scale production reduction in the fourth quarter [13]. Glass - Price and Profit - The market price has slightly declined this week. The price in Shahe is about 1,180 - 1,200 yuan/ton (down 80 - 100 yuan/ton), in Hubei, Central China, it is about 1,160 - 1,200 yuan/ton (down 80 - 100 yuan/ton), and in some large factories in the Jiangsu - Zhejiang region of East China, it is about 1,280 - 1,320 yuan/ton (down 20 - 40 yuan/ton) [16][20]. - The futures price has rebounded, the basis has strengthened, and the monthly spread remains weak. The profit of using petroleum coke as fuel is about 130 yuan/ton, and the profits of using natural gas and coal as fuel are about - 150 yuan/ton and 111 yuan/ton respectively [22][25]. Glass - Inventory and Downstream开工 - Recently, the transaction volume has significantly declined. The inventory in various regions has increased due to the decrease in spot transactions and market prices. The regional price difference tends to widen, with greater price cuts in Central China and Shahe and smaller cuts in the Jiangsu - Zhejiang region [32][36]. Photovoltaic Glass - Price and Profit - The overall domestic photovoltaic glass market has good transactions, and the inventory has been decreasing. The mainstream order price of 2.0mm coated panels is 10.5 - 11 yuan/square meter, a 2.38% increase from the previous week; the mainstream order price of 3.2mm coated panels is 18.5 - 19 yuan/square meter, a 1.35% increase from the previous week [42][44].

The sample inventory days are about 26.93 days, an 8.13% decrease from the previous week [45][46][50]. 纯碱 - Supply and Maintenance - Some soda ash plants have resumed production, and the operating rate has increased. The production capacity utilization rate of soda ash is 85.4%, up from 80.2% last week. The current weekly output of heavy soda ash is 423,000 tons/week. In the context of high production and high inventory, either manufacturers should increase production cuts, or the real - estate industry chain should recover to drive the recovery of glass demand [55][57]. 纯碱 - Price and Profit - The market quotation has been lowered, and the quotation reduction of traders is greater than that of manufacturers. The nominal price in Shahe and Hubei is about 1,250 - 1,300 yuan/ton. The high production and high inventory put pressure on near - month contracts, but during the peak position - shifting period, the market may gradually turn to positive spreads [70][73][75]. - The profit of the joint - soda method in East China (excluding Shandong) is 68 yuan/ton, and the profit of the ammonia - soda method in North China is 56 yuan/ton [79].

Core Viewpoints of the Report - The anti -内卷 driving force in the soda ash and glass markets is weakening, and the fundamentals are gradually taking the lead. The market trends are mainly oscillating weakly [14][23]. - For soda ash, supply is increasing, demand is stable, and the inventory is in an accumulating trend. The spot price is falling to narrow the basis. It is expected that the futures price will show a weakly oscillating trend next week [14]. - For glass, the daily production is stable, but due to the release of spot goods in the market, the inventory is increasing, and the demand growth is limited. The spot price is weak, and it is expected that the futures price will also show a weakly oscillating trend [23]. 3. Summary According to the Directory 3.1 Soda Ash 3.1.1 Supply - This week, the soda ash production was 74.5 tons, a week - on - week increase of 4.5 tons (6.4%). The daily production was 10.5 - 10.7 tons. The supply increased due to the capacity enhancement of some enterprises such as Shandong Haihua and Henan Junhua. It is expected that the weekly production next week will be over 75 tons. The large - scale maintenance is expected to start in September, but the maintenance premium and scale are limited [7]. - The theoretical profit of soda ash in China's joint - alkali method (double - ton) was 68.50 yuan/ton, a week - on - week decrease of 38 yuan/ton. The theoretical profit of the ammonia - alkali method was 56.20 yuan/ton, a week - on - week decrease of 0.90 yuan/ton. The coal price is rising, and the cost is increasing, while the spot price of soda ash is falling slightly [7]. 3.1.2 Demand - This week, the apparent demand for soda ash was 67.5 tons, a week - on - week decrease of 12.1%. The demand for heavy soda ash was 37.9 tons (a 9.5% decrease), and that for light soda ash was 29.7 tons (a 15.3% decrease). After a two - month upward trend, both the intermediate and downstream inventories are relatively sufficient, and the short - term replenishment willingness is not strong [10]. - The futures price first rose and then fell this week, and the spot goods in the market increased, causing the spot price to fall [10]. 3.1.3 Inventory - Upstream: The soda ash factory inventory continued to accumulate, reaching 186.5 tons, a week - on - week increase of 6.9 tons. Among them, the light soda ash inventory increased by 2.5 tons, and the heavy soda ash inventory increased by 4.5 tons. In terms of regions, except for Central and South China where the sales rate exceeded 100%, the inventory in Northwest China increased by 6 tons [13]. - Intermediate: The intermediate inventory showed an increasing trend, with the social inventory increasing by 16.4% to 44.9 tons, and the growth rate of social inventory slowed down. There were 3310 warehouse receipts [13]. - Downstream: For the soda ash inventory of float glass enterprises, in some sample factories, the inventory days decreased, while the inventory days including the goods to be delivered increased to varying degrees [13]. 3.1.4 Market Performance and Strategy - The market performance of soda ash was oscillating. With the weakening of the anti -内卷 driving force, the market showed differentiation. Considering the fundamentals, the supply increased, the demand was stable, and the inventory was accumulating. The spot price was falling. - Strategy: For single - side trading, it is expected to show a weak trend, and attention should be paid to macro - disturbances; for arbitrage, pay attention to the opportunity of going long FG01 and short SA01; for options, it is recommended to wait and see [14]. 3.2 Glass 3.2.1 Supply - The daily production of float glass was 15.96 tons, remaining stable week - on - week, with 223 production lines.

The supply was sufficient, the upstream inventory was accumulating, and enterprises reduced prices [17]. 3.2.2 Demand - After a two - month upward trend, both the intermediate and downstream inventories were relatively sufficient, and the short - term replenishment willingness was not strong. The deep - processing orders did not improve significantly. As of July 31, 2025, the average order days of national deep - processing sample enterprises was 9.55 days, a month - on - month increase of 2.7% and a year - on - year decrease of 1.55%. The deep - processing profit was still low [20]. 3.2.3 Market Performance and Strategy - This week, the glass market showed a downward trend. As the futures price fell, the spot goods in the market were released, negatively affecting the spot market. The inventory of national float glass sample enterprises increased by 3.95% week - on - week. The enterprise profit decreased slightly, and the supply side was not yet in the cold - repair loss area [23]. - Strategy: For single - side trading, it is expected to show a weak trend, and attention should be paid to macro - disturbances; for arbitrage, go long glass and short soda ash; for options, it is recommended to wait and see [23].
