1. Report Industry Investment Rating - No specific investment rating provided in the report 2. Core View of the Report - Supply of polysilicon is expected to increase due to potential复产 of some bases and release of new production capacity of leading companies in the second half of the year, while short - term demand is weak as June's PV new installation decreased significantly year - on - year and month - on - month. Therefore, the polysilicon market is expected to face continued adjustment next week, with prices likely to show a volatile trend due to cost and policy support but limited upside by downstream acceptance. Industrial silicon demand is steadily declining with supply also decreasing, maintaining a volatile state. The current advice is to wait and see or arrange put options [2] 3.

The central bank will implement a moderately loose monetary policy and consider promoting a reasonable recovery of prices. There are expectations of increased supply of polysilicon due to the复产 of some bases and new capacity release [2] 3.7 Key Points of View - The supply of polysilicon is expected to increase, while the demand is weak. The short - term demand for polysilicon is restricted by the low PV new installation in June. The operating rate of downstream PV enterprises is difficult to improve. It is expected that the polysilicon market will continue to adjust next week, with prices showing a volatile trend. Industrial silicon demand is declining, and the market remains volatile [2] 3.8 Key Concerns - There is no news today. The polysilicon market is in high - level volatility, and the PV symposium has not released much news. The market is still speculating on merger rumors. The operation suggestion is to wait and see or arrange put options [2]

1. Report Industry Investment Rating - Not mentioned in the provided content 2. Core View of the Report - Last week, industrial silicon showed a strong and volatile trend, mainly due to the strong price - holding atmosphere in each link of the photovoltaic industry chain. The polysilicon market had a lot of "rumors", but market transactions were relatively limited, and the anti - involution sentiment continued to ferment. It is expected that the futures price will maintain a volatile and strong operation in the short term [2][3][6]. 3. Summary According to Relevant Catalogs 3.1 Market Data | Contract | 8/15 Price | 8/8 Price | Change | Change Rate | Unit | | --- | --- | --- | --- | --- | --- | | Industrial silicon main contract | 8805.00 | 8710.00 | 95.00 | 1.09% | Yuan/ton | | Oxygen - passing 553 spot | 9400.00 | 9250.00 | 150.00 | 1.62% | Yuan/ton | | Non - oxygen - passing 553 spot | 9200.00 | 9100.00 | 100.00 | 1.10% | Yuan/ton | | 421 spot | 9750.00 | 9700.00 | 50.00 | 0.52% | Yuan/ton | | 3303 spot | 9600.00 | 9500.00 | 100.00 | 1.05% | Yuan/ton | | Silicone DMC spot | 11400.00 | 12150.00 | - 750.00 | - 6.17% | Yuan/ton | | Polysilicon dense material spot | 46.00 | 44.00 | 2.00 | 4.55% | Yuan/ton | | Industrial silicon social inventory | 54.5 | 54.7 | - 0.2 | - 0.37% | 10,000 tons | [4] 3.2 Market Analysis and Outlook - **Supply side**: The operating rate in Xinjiang rose to 57%, and the operating rates in Sichuan and Yunnan increased month - on - month, showing a marginally loose supply situation. As of August 14, the weekly output of industrial silicon was 84,700 tons, a month - on - month increase of 1.5% and a year - on - year decrease of 16.3%. The number of open furnaces in the three major production areas remained at 280, and the overall open - furnace rate slightly rose to 35.2% [6][7][8]. - **Demand side**: Polysilicon enterprises had a strong price - holding atmosphere, but transactions were limited near the end of the signing period. The inventory in the silicon wafer market decreased significantly, and most integrated enterprises tended to reduce production. Photovoltaic cell manufacturers mainly executed existing orders, and there might be resistance to the increase in domestic export orders. The component end showed a weak and volatile trend, and terminal demand was poor [2][6][8]. - **Inventory**: As of August 15, the national social inventory of industrial silicon decreased to 545,000 tons, a month - on - month decrease of 2,000 tons. The warehouse receipt inventory of the Guangzhou Futures Exchange continued to rise to 50,599 lots, equivalent to 253,000 tons [9]. 3.3 Industry News - The automotive and photovoltaic industries held symposiums against disorderly competition. In 2024, the production capacity of Chinese chip manufacturers increased by 15%. In 2025, domestic wafer foundries will be the main force in the increase of mature - process production capacity, but price trends will be suppressed. Some enterprises are exploring ways to break through the low - level competition dilemma, such as Ruixin Micro focusing on basic capabilities and high - end markets [11]. - In the second half of 2025, the DDR4 market was in short supply, and prices rose strongly. The tight supply and demand in the DDR market also pushed up the contract price of Mobile DRAM. The third - quarter increase in LPDDR4X was the largest in a single quarter in the past decade. The demand for semiconductor hardware was growing steadily, and the storage sector was expected to continue to rise in the third and fourth quarters [12]. 3.4 Relevant Charts - The report provides 10 charts, including those related to industrial silicon production, export volume, social inventory, warehouse receipt inventory, production in major production areas, and prices of various products such as organic silicon DMC, polysilicon, and industrial silicon [15][18].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - Nickel: Under the fundamental logic, it fluctuates in a narrow range, and the long - term logic is under pressure. However, there are frequent events in Indonesia, so be vigilant against the risk of news - driven stimulation [4]. - Stainless steel: The pressure at the real - end still needs to be continuously alleviated, and the steel price fluctuates [5]. - Industrial silicon: Pay attention to the resumption rhythm of upstream factories [34]. - Polysilicon: There will be more event disturbances next week. The main idea is to go long on dips [35]. - Lithium carbonate: Supply is weak while demand is strong, and the price is strengthening [56]. 3. Summaries According to Related Catalogs Nickel - **Fundamentals**: The marginal operation of the fundamentals is relatively stable. The global refined nickel's visible inventory shows a gentle increase, dragging down the upper limit of nickel prices. The long - term low - cost supply increment may change the cost curve pattern. In the short - term and the second half of the year, the nickel price valuation may be at the window boundary of the ferronickel conversion path. The inventory at the ferronickel link has slightly decreased, slightly boosting the upper limit of the nickel price, but the amplitude is limited. The overall decline of the ore price is relatively mild, and the support has weakened slightly, but it is still difficult for the price to fall sharply. The hype of nickel ore contradictions may decrease, limiting the elasticity of nickel prices [4]. - **Market News Impact**: Indonesia may crack down on illegal mining, change the RKAB approval cycle, and re - evaluate the nickel ore HPM formula. These events increase the risk of short - selling at low levels and add uncertainty to the nickel price [4]. - **Inventory Changes**: China's refined nickel social inventory increased by 1,963 tons to 41,286 tons. LME nickel inventory decreased by 570 tons to 211,662 tons [6][7]. Stainless Steel - **Fundamentals**: The pressure at the real - end still needs to be continuously alleviated. The long - side logic focuses on the decline of inventory at a high level, the reduction of factory inventory pressure in July, and the potential reduction in supply due to policy tightening. The short - side logic comes from the actual supply - demand situation, where the alleviation of pressure needs to be continuous, and the supply elasticity may limit the upside [5]. - **Inventory and Production**: Social inventory has declined slightly for five consecutive weeks, and the factory inventory pressure in July has decreased. The stainless steel production in August is 3.25 million tons, with a marginal increase. The production in Indonesia in August is 420,000 tons [5]. Industrial Silicon - **Price Trend**: The industrial silicon futures fluctuated this week, and the spot price increased. The futures price first rose, then fell, and then rose again, influenced by other varieties and macro - sentiment. The spot prices in Xinjiang and Inner Mongolia increased [30]. - **Supply - Demand Fundamentals**: On the supply side, the weekly industry inventory decreased slightly. Factories in the southwest and northwest regions had some resumptions, but the rhythm was slow. On the demand side, the short - term demand of downstream industries increased marginally, with the polysilicon and organic silicon sectors supporting consumption [31][32]. - **Market Outlook**: Pay attention to the resumption rhythm of upstream factories. Before a large - scale resumption, the futures price may follow the coking coal futures, but the long - term fundamental direction is bearish. It is recommended to short at high levels and take profits at low levels [34]. Polysilicon - **Price Trend**: The polysilicon futures fluctuated widely this week, showing a relatively strong trend overall. The spot market had some transactions, but the price did not show obvious improvement [30]. - **Supply - Demand Fundamentals**: The short - term weekly production remained at a high level, and the upstream inventory increased. The demand from the silicon wafer side improved, and the production in August increased slightly compared with July [32][33]. - **Market Outlook**: There will be more event disturbances next week. The main idea is to go long on dips. The spot market's signing is approaching the end, and the terminal demand may decrease in September. It is recommended to take profit on the PS2511 - PS2512 inter - period positive spread and maintain the inter - period reverse spread idea [35]. Lithium Carbonate - **Price Trend**: The lithium carbonate futures price increased significantly, and the spot price also rose. The SMM basis and the spread between contracts changed accordingly [54]. - **Supply - Demand Fundamentals**: On the supply side, production in Jiangxi and Qinghai was affected, and there were concerns about future production. On the demand side, the downstream production demand in August improved significantly. The social inventory decreased slightly, and the number of futures warrants increased [55]. - **Market Outlook**: Due to supply disturbances, the lithium price is expected to remain strong for about a month. If the downstream demand in September strengthens, the price will continue to be strong. The futures main contract price is expected to range from 85,000 to 95,000 yuan/ton [56][57].

Core Viewpoints of the Report - The fundamentals of the industrial silicon and polysilicon industries are weak, but the market is driven by events. The short - term investment strategies for industrial silicon and polysilicon are recommended, while the long - term price of polysilicon is expected to rise [1][2][3][4] 3. Summary According to Relevant Catalogs 3.1 Industrial Silicon/Polysilicon Industry Chain Prices - This week, the Si2511 contract of industrial silicon increased by 95 yuan/ton to 8805 yuan/ton. The SMM spot price of East China oxygen - blown 553 increased by 150 yuan/ton to 9400 yuan/ton, and the price of Xinjiang 99 increased by 150 yuan/ton to 8700 yuan/ton. The PS2511 contract of polysilicon increased by 1950 yuan/ton to 52740 yuan/ton. The transaction price of N - type re - feeding material increased by 200 yuan/ton to 47400 yuan/ton [10][11] 3.2 Fundamentals Are Weak, but the Market Is Driven by Events 3.2.1 Industrial Silicon - This week, the main contract of industrial silicon futures fluctuated. New furnaces were opened in Xinjiang, Sichuan, Gansu, and Ningxia. The SMM industrial silicon social inventory decreased by 0.20 million tons, and the sample factory inventory increased by 0.11 million tons. Xinjiang's large factories have further复产 plans. Considering the remaining time of the wet season, the later - stage increase in southern production is limited. Downstream maintains rigid demand procurement. In July, the industrial silicon balance sheet showed a de - stocking of about 30,000 tons. In August, the supply side is expected to have a marginal increase of about 40,000 tons, but due to the large - scale复产 of polysilicon, industrial silicon may still de - stock [12] 3.2.2 Organic Silicon - This week, the price of organic silicon fluctuated downward. The production load of monomer factories remained stable. Hesheng's Sichuan plant plans to resume production. The overall enterprise operating rate was 77.7%, the weekly output was 51,400 tons, a 0.39% increase, and the inventory was 48,500 tons, a 2.97% increase. Terminal demand has not improved substantially, and the price is expected to be weak [12][13] 3.2.3 Polysilicon - This week, the main contract of polysilicon futures fluctuated strongly. Spot trading changed little. The factory inventory increased by 0.9 million tons to 242,000 tons. Although the price limit has been implemented, production cuts have not started. The output in August is expected to reach 125,000 - 130,000 tons, resulting in a monthly surplus of 20,000 tons. Terminal demand is weak, but the futures market is more affected by policies and news [13] 3.2.4 Silicon Wafers - This week, the price of silicon wafers was stable overall, with some models slightly decreasing. The inventory increased by 0.69GW to 19.80GW. The production schedule in August is 53GW. Terminal demand is weak, but silicon wafer manufacturers have a strong willingness to support prices. In the short term, the price may fluctuate and may decline later [14] 3.2.5 Battery Cells - This week, the price of battery cells was stable. The inventory increased by 1.12GW to 4.98GW. The production schedule in August is about 58GW. The price increase of battery cells was not smoothly transmitted to the component link. With the possible extension of the component export tax - refund cancellation policy, the price of battery cells is expected to decline [15] 3.2.6 Components - This week, the price of components fluctuated. The price of centralized projects showed signs of loosening, and the distributed spot price was temporarily stalemate. The production schedule is 45GW. Overseas demand decreased due to the possible policy extension. Domestic centralized power stations are still waiting and watching. The market logic may put pressure on component prices, and policy support is needed [16] 3.3 Investment Recommendations 3.3.1 Industrial Silicon - Based on the reality of Xinjiang's large factories'复产 falling short of expectations and the large - scale increase in polysilicon production, the fundamentals of industrial silicon have improved and are in a de - stocking state. However, considering the future复产 of large factories and polysilicon production cuts, the fundamentals are not optimistic. In the short term, a strategy of buying on dips is recommended, with the risk being the large factories'复产 [3][17] 3.3.2 Polysilicon - The fundamentals are bearish for the market. Middle - section deliverable enterprises are actively hedging, and more warehouse receipts will be registered. The market has strong speculative properties and is supported at 49,000 yuan/ton. In the short term, the price may range from 45,000 - 57,000 yuan/ton, and in the long term, it is expected to exceed 60,000 yuan/ton. A strategy of bullish on pullbacks is recommended, and attention can be paid to the 11 - 12 reverse arbitrage opportunity at about - 2000 yuan/ton [4][18] 3.4 Hot News - The US launched anti - dumping and counter - vailing investigations on crystalline silicon photovoltaic cells imported from India, Indonesia, and Laos. The ITC will make an initial ruling on industrial damage by September 2, 2025. If it rules in favor, the US Department of Commerce will continue the investigation and make initial rulings on counter - vailing and anti - dumping by October 13, 2025, and December 26, 2025, respectively [19] - Xingfa's 100,000 - ton industrial silicon project in Inner Mongolia was highly recognized by a joint observation group.

Group 1: Natural Rubber Core View - Supply side: Rainfall in the producing areas may affect the release of new rubber, and the raw material procurement price is strong. Future focus is on the raw material situation during the peak production period. Demand side: Current channel trading is average, some agents replenish goods as needed and mainly control inventory. Terminal demand has no obvious improvement, and channels are cautious about restocking. Market sentiment has cooled recently. If the raw material volume increases smoothly during the peak production period, consider short - selling at high prices [2]. Summary of Related Catalogs - **Spot Price and Basis**: The price of Yunnan state - owned standard rubber (SCRWF) in Shanghai remained unchanged at 14,800 yuan/ton. The basis of whole milk switched to the 2509 contract increased by 165 yuan/ton to - 832 yuan/ton, with a growth rate of 16.50%. The price of Thai standard mixed rubber decreased by 200 yuan/ton to 14,400 yuan/ton, a decline of 1.37% [2]. - **Inter - month Spread**: The 9 - 1 spread increased by 10 yuan/ton to - 1000 yuan/ton, with a growth rate of 0.99%; the 1 - 5 spread decreased by 5 yuan/ton to - 65 yuan/ton, a decline of 8.33%; the 5 - 9 spread decreased by 2 yuan/ton to 1065 yuan/ton, a decline of 0.47% [2]. - **Fundamental Data**: In June, Thailand's production was 392,600 tons, a 44.23% increase; Indonesia's production was 176,200 tons, a 12.03% decrease; India's production was 62,400 tons, a 30.82% increase; China's production was 103,200 tons, a 6.8 - ton increase.

Group 2: Industrial Silicon Core View - Industrial silicon spot prices are stable, and the main contract has rebounded. Although the market is not optimistic about the capacity clearance and self - discipline of industrial silicon, in the context of the anti - involution policy, the overall operating price center of commodities has moved up, and industrial silicon is no exception. The cost of raw materials such as coal may increase, which will push up the cost of industrial silicon and raise the future price center. In August, the supply and demand of the industrial silicon market both increase, and it is expected to reach a tight balance. The main price fluctuation range may be between 8,000 - 9,500 yuan/ton. If the price drops to 8,000 - 8,500 yuan/ton, consider buying on dips. The inventory has increased, but the warehouse receipts are still decreasing. The main contract has shifted to SI2511, and the position of the 09 contract has decreased to about 50,000 lots. Technically, the hourly line has weakened, and it may continue to fluctuate weakly in the short term [4]. Summary of Related Catalogs - **Spot Price and Basis of the Main Contract**: The price of East China oxygen - passing SI5530 industrial silicon remained unchanged at 9,400 yuan/ton; the basis (based on oxygen - passing SI5530) decreased by 75 yuan/ton to 725 yuan/ton, a decline of 9.38%. The price of East China SI4210 industrial silicon remained unchanged at 9,750 yuan/ton; the basis (based on SI4210) decreased by 75 yuan/ton to 275 yuan/ton, a decline of 21.43% [4]. - **Inter - month Spread**: The 2509 - 2510 spread decreased by 45 yuan/ton to - 40 yuan/ton, a decline of 900.00%; the 2510 - 2511 spread increased by 30 yuan/ton to - 5 yuan/ton, a growth of 85.71% [4]. - **Fundamental Data (Monthly)**: National industrial silicon production was 338,300 tons, a 3.23% increase; Xinjiang's production was 150,300 tons, a 15.21% decrease; Yunnan's production was 41,200 tons, a 153.86% increase; Sichuan's production was 48,500 tons, a 31.05% increase. The national operating rate was 52.61%, a 2.47% increase; Xinjiang's operating rate was 52.59%, an 18.21% decrease; Yunnan's operating rate was 32.89%, a 133.76% increase; Sichuan's operating rate was 36.96%, a 56.81% increase.

Group 3: Polysilicon Core View - In August, the supply and demand of polysilicon both increase, but the supply growth rate is larger, and there is still pressure to accumulate inventory. Due to the previous sharp price increase above the full - cost level, it is expected that the number of warehouse receipts will further increase. If there is new progress in capacity integration or clearance, polysilicon prices are expected to rise again. Otherwise, it may fluctuate and decline under the pressure of inventory and warehouse receipt increase. Currently, there are news of production restrictions, and future attention should be paid to the enterprise's operating conditions and production changes. The main price fluctuation range may be between 45,000 - 58,000 yuan/ton. After the price returns to the lower edge of the cost range, consider buying on dips. When the price is high, consider buying put options to short. The position of the 09 contract has decreased to about 18,000 lots, and investors are advised to pay attention to position control and risk management in advance [5]. Summary of Related Catalogs - **Spot Price and Basis**: The average price of N - type re - feed material remained unchanged at 47,000 yuan/ton; the average price of N - type granular silicon remained unchanged at 44,500 yuan/ton.

The number of polysilicon warehouse receipts increased by 330 to 5,480 [5]. Group 4: Logs Core View - From the fundamental perspective, the demand side currently remains strong at the level of 64,000 cubic meters. The inventory has significantly decreased due to fewer unloading ports and strong shipment volume. From the perspective of shipments from New Zealand, it is expected that the overall shipments in August will be the same as in July. Currently, short - term demand is strong, but the medium - and long - term demand improvement needs to be verified. This week, the futures market was weakened by new warehouse receipts.

Group 5: Glass and Soda Ash Core View - **Soda Ash**: Recent information from Qinghai has affected the market sentiment, but it has no impact on the supply in Qinghai for now. The weekly production has significantly rebounded, and the inventory has returned to the accumulation stage, with obvious overall over - supply in the fundamentals. Recently, the spot sales have weakened. In the medium term, after the photovoltaic installation rush in the second quarter, the growth of photovoltaic glass production capacity has slowed down, the float glass production capacity has remained flat, and there is still pressure on supply and demand in the future, with a further cold - repair expectation. Therefore, there is no growth expectation for the overall demand of soda ash. If there is no actual capacity exit or load reduction in the future, the inventory will be further pressured. In August, which is the traditional summer maintenance season for the soda ash industry, track the implementation of policies and the load adjustment of soda ash plants. The previous market increase was due to news, and consider short - selling at high prices [7]. - **Glass**: The market has been weak recently, and the negative feedback in the market continues. After the previous sharp price increase, the inventory has shifted from manufacturers to middle - stream traders and futures - cash traders, and the futures - cash inventory in Shahe has reached a new high. In the future, there may be a rush to sell during the shipment process. In Hubei, the inventory has also shifted, and the middle - stream faces shipment pressure, which will squeeze the manufacturers' shipments. Therefore, it is difficult to further increase the overall spot price. Fundamentally, the deep - processing orders are weak, the operating rate of low - emissivity glass is continuously low, and there is certain pressure on the rigid demand side of glass. In the long run, the real - estate cycle is at the bottom, and the completion volume is shrinking. Eventually, the industry needs to clear the excess capacity to solve the dilemma. In August, track the implementation of local policies and the restocking performance of downstream enterprises near the peak seasons of "Golden September and Silver October". Currently, the market sentiment has declined, and short positions can be held, while being vigilant about the market fluctuations caused by macro - factors [7].
