Group 1: Report Industry Investment Rating - No relevant information provided Group 2: Core Viewpoints of the Report - After the holiday, both raw material and synthetic rubber prices declined. In the spot market, transactions were generally at low prices. With the downward trend of spot prices, the inventory of trading enterprises decreased. After the price dropped to a relatively low level, as the liquidity of the spot market improved, the active participation of downstream buyers is expected to drive down the spot inventory [2]. - In terms of demand, most enterprises that had maintenance during the holiday resumed production as planned, and the capacity utilization rate of sample enterprises increased significantly.

Report Industry Investment Rating No relevant content provided. Core View of the Report The inventory accumulation trend of alumina continues, and the over - capacity pattern in the smelting end is hard to change in the short term. However, the increasing expectation of the Fed's interest rate cut may drive the non - ferrous sector to run stronger, and the current price is approaching the cost line of most manufacturers, so the follow - up production cut expectation is strengthened. It is recommended to wait and see in the short term. The reference operating range of the domestic main contract AO2601 is 2600 - 3000 yuan/ton, and attention should be paid to supply - side policies, Guinea's ore policies, and the Fed's monetary policy [12][13]. Summary by Relevant Catalogs 1. Weekly Assessment - **Futures Price**: As of 3 p.m. on October 17, the alumina index fell 1.82% to 2809 yuan/ton this week, with positions increasing by 23,000 lots to 458,000 lots. Due to the uncertainty of Sino - US negotiations and the high - start and high - inventory pattern of alumina, the futures price fluctuated downward. The Shandong spot price was 2815 yuan/ton, with a premium of 46 yuan/ton over the 11 - contract. The spread between the first and third contracts closed at - 29 yuan/ton [11][24]. - **Spot Price**: This week, the spot prices of alumina in various regions continued to decline. The spot prices in Guangxi, Guizhou, Henan, Shandong, Shanxi, and Xinjiang decreased by 35 yuan/ton, 25 yuan/ton, 40 yuan/ton, 50 yuan/ton, 40 yuan/ton, and 40 yuan/ton respectively. The continuous inventory accumulation put pressure on the spot price [11][21]. - **Inventory**: The total social inventory of alumina increased by 63,000 tons to 4.639 million tons this week. The in - plant inventory of electrolytic aluminum plants, the in - plant inventory of alumina plants, the in - transit inventory, and the port inventory increased by 11,000 tons, 0 tons, 23,000 tons, and 29,000 tons respectively. The total warehouse receipts of SHFE alumina increased by 45,200 tons to 221,300 tons, and the delivery warehouse inventory was 239,600 tons, an increase of 33,000 tons from last week [11][70][73]. - **Comprehensive Analysis**: The ore price has short - term support but may be under pressure after the rainy season. The over - capacity pattern in the alumina smelting end is hard to change in the short term, and the inventory accumulation trend continues. However, the increasing expectation of the Fed's interest rate cut may drive the non - ferrous sector to run stronger, and the current price is approaching the cost line of most manufacturers, so the follow - up production cut expectation is strengthened. It is recommended to wait and see in the short term [12][13]. 2. Spot and Futures Prices - **Spot Price**: The spot prices of alumina in various regions continued to decline this week, with different degrees of decline in different regions. The continuous inventory accumulation put pressure on the spot price [21]. - **Futures Price and Basis**: The alumina index fell this week, and the futures price fluctuated downward. The Shandong spot price had a premium over the 11 - contract, and the spread between the first and third contracts was negative [24]. - **Bauxite Price**: The bauxite prices in various regions remained unchanged this week. After the rainy season in Guinea, the ore shipment increased, and due to profit contraction, alumina enterprises' willingness to lower prices increased. With the high port inventory, the ore price is expected to decline [27]. 3. Supply Side - **Bauxite Production**: In September 2025, China's bauxite production was 4.88 million tons, a year - on - year decrease of 2.3% and a month - on - month decrease of 3%. The cumulative production in the first nine months was 45.74 million tons, a year - on - year increase of 3.28%. Affected by the rainy season and environmental policies, domestic bauxite production decreased [31]. - **Bauxite Import**: In August 2025, bauxite imports were 18.29 million tons, a year - on - year increase of 17.65% and a month - on - month decrease of 8.84%. The cumulative imports in the first eight months were 141.76 million tons, a year - on - year increase of 31.38%. From different importing countries, imports from Guinea and Australia had different changes [33][35][37]. - **Bauxite Inventory**: In September, China's bauxite inventory decreased by 1.04 million tons, with a total inventory of 52.27 million tons, still at a high level in the past five years. In key regions, the inventory in Shanxi and Henan decreased [40]. - **Alumina Production**: In September 2025, alumina production was 7.746 million tons, a year - on - year increase of 12.69% and a month - on - month decrease of 1.68%. The cumulative production in the first nine months was 66.84 million tons, a year - on - year increase of 9.82%. The operating capacity in September was 97 million tons, a year - on - year increase of 14.12% and a month - on - month increase of 2.54% [42][45]. - **Alumina Plant Profit**: The alumina spot price declined, and the profit of alumina plants was under pressure. Different regions had different profit situations, with some regions approaching or in a loss state [48]. - **Alumina Import and Export**: In August 2025, alumina had a net export of 86,000 tons. The import window opened recently, and it is expected that the import volume in September and October will gradually increase, which may further intensify the domestic supply - surplus situation. As of October 17, the Australian FOB price decreased, and the import window was closed [50][52]. - **Overseas Alumina Production**: In September 2025, overseas alumina production was 5.24 million tons, a year - on - year increase of 6.66% and a month - on - month decrease of 2.62%. The cumulative production in the first nine months was 46.5 million tons, a year - on - year increase of 3.06% [54]. 4. Demand Side - **Electrolytic Aluminum Production**: In September 2025, China's electrolytic aluminum production was 3.68 million tons, a year - on - year increase of 2.73% and a month - on - month decrease of 2.86%. The cumulative production in the first nine months was 33.07 million tons, a year - on - year increase of 2.73% [59]. - **Electrolytic Aluminum Operation**: In September 2025, the operating capacity of electrolytic aluminum was 44.56 million tons, an increase of 160,000 tons from the previous month. The operating rate increased by 0.35% to 97.47% [62]. 5. Supply - Demand Balance The alumina supply - demand balance table shows the situation of supply and demand, import and export, and related data in different months from January to December 2025. The supply and demand situation varies in different months, and there are differences in net exports [65]. 6. Inventory The total social inventory of alumina increased this week, and the warehouse receipts of SHFE and the delivery warehouse inventory also increased. The continuous inventory accumulation shows that the supply in the market is relatively abundant [70][73].

1. Investment Ratings No investment ratings for the industries are provided in the reports. 2. Core Views Methanol - The price may continue to fluctuate under the game of supply and demand. Focus on the stability of overseas device operation, the customs - clearance efficiency of sanctioned vessels, and actual arrival performance. Pay attention to the port destocking rhythm and the implementation effect of overseas gas - limiting expectations [1]. Polyolefins (LLDPE & PP) - The inventory pressure after the holiday is still significant. The supply pressure is prominent in the medium - and long - term, and the demand lacks highlights. The upside space of the 01 contract is limited [5]. Caustic Soda - There is demand support in the medium - and long - term, but it is weak in the short term. It was previously recommended to be bearish, and now the short positions can be temporarily closed as the market stabilizes [8]. PVC - The short - term disk may continue to be under pressure. Although the supply pressure has slightly eased and exports have recovered, the demand in the peak season is weak. Pay attention to cost support and downstream demand performance [8]. PX - The supply and demand are expected to be weak in the fourth quarter. It will mainly fluctuate at a low level in the short term. It is recommended to wait and see and look for short - selling opportunities on rebounds, and mainly conduct reverse spreads on the monthly spread [9]. PTA - The short - term drive is limited, and it will mainly fluctuate at a low level. It is recommended to wait and see TA, pay attention to the support around 4500, and conduct rolling reverse spreads on TA1 - 5 [9]. Ethylene Glycol - It is expected to accumulate inventory in October, and the supply - demand structure is weak in the far - month. It is recommended to short EG01 on rallies, hold the seller of the out - of - the - money call option EG2601 - C - 4350, and conduct reverse spreads on EG1 - 5 [9]. Short Fibers - The absolute price is still under pressure in the short term, but it is relatively strong compared to raw materials due to low inventory. It is recommended to have the same strategy as PTA for the unilateral position, and widen the processing margin at a low level [9]. Bottle Chips - It is likely to enter the seasonal inventory accumulation channel. PR follows the cost end, and the processing margin improves in the short term. It is recommended to have the same strategy as PTA for the unilateral position, and the main contract processing margin is expected to fluctuate between 350 - 500 yuan/ton [9]. Pure Benzene - The overall supply and demand in October are expected to be loose, and the price drive is weak. BZ2603 follows the fluctuations of styrene and oil prices [10]. Styrene - The supply - demand is expected to be loose, and the price is still under pressure in the short term. EB11 should be treated as a short - selling opportunity on rebounds [10]. 3.

1. Report Industry Investment Rating No information provided regarding the report industry investment rating. 2. Core Viewpoints of the Report - The trade situation remains volatile, and the weakening of the US dollar index has led to new highs in precious metal prices. The supply - demand relationship of copper provides strong support for prices, and short - term price declines may be limited. Aluminum prices are expected to continue to oscillate strongly. Short - term trends of lead, zinc, tin, nickel, lithium carbonate, alumina, stainless steel, and cast aluminum alloy are also analyzed, with corresponding price ranges provided [2][3][6]. 3. Summary by Metal Copper - **Market Information**: Trade situation is volatile, the US dollar index is weak, and copper prices oscillate upwards. LME copper inventory decreases, domestic electrolytic copper social inventory and bonded area inventory increase slightly, and the spot import loss narrows. The refined - scrap price difference narrows [2]. - **Strategy Viewpoint**: Overseas copper mine production cuts and reduced domestic refined copper output tighten supply expectations, and short - term price declines may be limited. The reference operating range for the Shanghai copper main contract is 84,500 - 86,000 yuan/ton, and for the LME copper 3M contract is 10,500 - 10,750 US dollars/ton [3]. Aluminum - **Market Information**: Domestic inventory decreases, and the US may introduce an automobile tariff grace period. Aluminum prices are strongly trending. LME aluminum inventory decreases, and domestic aluminum ingot and aluminum rod inventories decline [5]. - **Strategy Viewpoint**: With the increase in the domestic aluminum - water ratio, seasonal consumption recovery, and strong exports, the pressure of aluminum ingot inventory accumulation is small, and prices may continue to oscillate strongly. The reference operating range for the Shanghai aluminum main contract is 20,900 - 21,200 yuan/ton, and for the LME aluminum 3M contract is 2,750 - 2,820 US dollars/ton [6]. Lead - **Market Information**: The Shanghai lead index closes slightly lower. LME lead price declines, and domestic social inventory remains unchanged. The refined - scrap price difference is 75 yuan/ton [8]. - **Strategy Viewpoint**: The apparent lead ore inventory rises slightly, and the production of primary lead smelting remains high. The waste lead inventory declines, and the production of secondary lead smelting is at a low level. The lead ingot factory inventory accumulates. The short - term Shanghai lead is expected to be strong [9]. Zinc - **Market Information**: The Shanghai zinc index closes slightly lower, and the LME zinc price rises. Domestic social inventory accumulates slightly, and the zinc ingot export window opens [10]. - **Strategy Viewpoint**: Domestic zinc smelting enterprises operate normally during holidays, and most downstream enterprises maintain normal production. The LME registered zinc warehouse receipts are at a low level, and there is still a structural risk. Short - term Shanghai zinc is expected to oscillate at a low level with increased volatility [11]. Tin - **Market Information**: The Shanghai tin main contract price declines slightly. The import of tin ore is at a low level due to slow resumption of production in Myanmar and Indonesia's crackdown on illegal mining. The smelting enterprise operating rate is low, and downstream demand is mixed. The consumption margin improves during the peak season, but high prices still suppress consumption [13]. - **Strategy Viewpoint**: Short - term supply and demand are in a tight balance, and with the recovery of peak - season demand, tin prices may oscillate at a high level. It is recommended to wait and see. The reference operating range for the domestic main contract is 270,000 - 290,000 yuan/ton, and for overseas LME tin is 34,000 - 36,000 US dollars/ton [14]. Nickel - **Market Information**: Nickel prices oscillate. Spot market transactions are average, and brand premiums rise slightly. Nickel ore prices are stable, nickel - iron prices are weak, and MHP coefficient prices are high [15]. - **Strategy Viewpoint**: Short - term trade frictions may reduce market risk appetite, but the impact on nickel prices is relatively small. In the short term, weak nickel - iron prices and high refined nickel inventory pressure may drag down nickel prices, but in the long term, there are supporting factors. It is recommended to wait and see, and consider buying on dips if the price drops significantly. The reference operating range for the short - term Shanghai nickel main contract is 115,000 - 128,000 yuan/ton, and for the LME nickel 3M contract is 14,500 - 16,500 US dollars/ton [16][17]. Lithium Carbonate - **Market Information**: The spot index of lithium carbonate rises, and the futures contract price also increases. The market's available spot is tight, and the premium strengthens [19]. - **Strategy Viewpoint**: Social inventory and exchange warehouse receipts continue to decline. If consumption remains strong and resonates with the macro - environment, lithium prices may break through the upper limit. Short - term strong oscillation is more likely. The reference operating range for the Guangzhou Futures Exchange lithium carbonate 2601 contract is 73,000 - 77,800 yuan/ton [20]. Alumina - **Market Information**: The alumina index declines slightly, and the trading volume increases. The spot price in Shandong drops, and the import window closes. The futures warehouse receipts decrease [22]. - **Strategy Viewpoint**: Ore prices have short - term support but may face pressure after the rainy season. The over - capacity situation in the alumina smelting end is difficult to change in the short term, and inventory accumulation continues. It is recommended to wait and see for macro - sentiment resonance. The reference operating range for the domestic main contract AO2601 is 2,600 - 3,000 yuan/ton, and attention should be paid to supply - side policies, Guinean ore policies, and the Fed's monetary policy [23]. Stainless Steel - **Market Information**: The stainless steel main contract price rises slightly, and the trading volume increases. Spot prices in different markets show different trends, and raw material prices are stable. Social inventory decreases, but 300 - series inventory increases [25]. - **Strategy Viewpoint**: After the holiday, social inventory accumulates significantly, but terminal consumption is flat. The market does not show the characteristics of the traditional peak season. Spot prices decline, and market sentiment is pessimistic. The market trend is expected to be weak [26]. Cast Aluminum Alloy - **Market Information**: The AD2511 contract price rises, the trading volume and open interest increase. The price of domestic mainstream ADC12 is stable, and the inventory of recycled aluminum alloy ingots in the domestic mainstream market decreases [28]. - **Strategy Viewpoint**: The firm cost provides support for the aluminum alloy price, but the current market sentiment is volatile, and the delivery pressure of the near - month contract is relatively large, limiting the upward price space [29].

1. Report Industry Investment Ratings - Copper: Not clearly defined [1] - Aluminum: Not clearly defined [1] - Alumina: Not clearly defined [1] - Cast Aluminum Alloy: Not clearly defined [1] - Zinc: ★☆☆ (One star, indicating a bullish bias) [1] - Nickel and Stainless Steel: ★☆☆ (One star, indicating a bullish bias) [1] - Tin: ★☆☆ (One star, indicating a bullish bias) [1] - Lithium Carbonate: Not clearly defined [1] - Industrial Silicon: Not clearly defined [1] - Polysilicon: ★☆☆ (One star, indicating a bullish bias) [1] 2. Core Viewpoints of the Report - The report provides a daily analysis of various non - ferrous metals, including their price trends, supply - demand fundamentals, and market sentiment, and gives corresponding price trend forecasts for each metal [2][3][4] 3. Summary by Metal Copper - Thursday, SHFE copper fluctuated around 85,000 yuan. SMM spot copper was reported at 85,175 yuan, with a premium of 60 yuan in Shanghai. Social inventory increased by 5,500 tons to 177,500 tons this week [2] - The US government shutdown led to a lack of physical indicators. The Fed's Beige Book showed weakening consumer spending and labor force, increasing the probability of interest rate cuts. Copper prices are expected to fluctuate temporarily [2] Aluminum, Alumina, and Aluminum Alloy - SHFE aluminum rebounded today, with spot aluminum in East China at par. In the off - season, the apparent consumption of aluminum was basically flat year - on - year. Aluminum ingot and aluminum rod social inventories decreased by 23,000 tons and 5,000 tons respectively compared to Monday. Since the National Day, inventory performance has been neutral. Macro sentiment is volatile, and SHFE aluminum will test the previous high resistance in the short term [3] - Cast aluminum alloy follows the fluctuation of SHFE aluminum. The Baotai spot price is 20,600 yuan. Scrap aluminum supply is tight, and the expected tax policy adjustment increases enterprise costs. However, the industry inventory is at a high level, and the SHFE warehouse receipts reach 43,000 tons. Whether the price difference with SHFE aluminum can continue to narrow remains to be seen [3] - Alumina's operating capacity is at a historical high, and industry inventory continues to rise. There is an obvious supply surplus, and the spot index in various regions continues to decline at a rate of about 10 yuan per day. The average cost in Shanxi and Henan in September was around 3,000 yuan. The current index price is not enough to trigger cash - loss production cuts in Shanxi and Henan but is approaching it. Alumina is mainly in a weak operation [3] Zinc - Although the spot export window has briefly opened, there has been no substantial large - scale export of zinc ingots. LME zinc inventory is at a low level of 38,000 tons, and the 0 - 3 month premium is at a high level of $139.83/ton. Overseas supply is tight, but terminal consumption has not improved significantly, and downstream acceptance of high - priced zinc is insufficient. LME zinc is expected to fluctuate at a high level [4] - Overseas smelter profits have recovered, and overseas zinc ingot supply may increase in the fourth quarter. The hidden inventory cannot be verified for the time being. Focus on tracking changes in LME zinc inventory. Some smelters in Gansu and Guangxi in China plan to conduct maintenance, and the room for further expansion of the domestic - foreign price difference is limited. The fundamentals are weak at home and strong abroad, and the export window is about to open. SHFE zinc is expected to consolidate at a low level, LME zinc will fluctuate at a high level, and the SHFE - LME ratio will fluctuate widely around the opening of the export window [4] Nickel and Stainless Steel - SHFE nickel is in a weak operation, and market trading is light. After the interest rate cut, the tendency of long - position holders to take profits is prominent. Sino - US frictions have increased uncertainty, and the macro - environment is gradually moving towards lower risk appetite [7] - The fundamentals of stainless steel are weak. During the traditional peak consumption season, downstream demand recovery is limited, market transactions are light, and social inventory has stopped falling and started to rise. The price of high - nickel ferro - nickel is 953 yuan per nickel point. Pure nickel inventory has increased by nearly 3,000 tons to 43,700 tons, nickel - iron inventory has increased by 600 tons to 29,200 tons, and stainless steel inventory has decreased by 3,400 tons to 909,000 tons. SHFE nickel's bullish factors are exhausted, and nickel prices are in a weak operation with a downward - biased center [7] Tin - SHFE tin fluctuated and closed up at the 280,000 - yuan level, and spot tin was reported at 281,200 yuan. The market has digested the Indonesian theme, and Indonesia's tin ingot exports rebounded to 484 tons in September. Hold short positions at high levels [8] Lithium Carbonate - The futures price of lithium carbonate rebounded, and market trading was light. Sino - US frictions have a short - term impact on market risk appetite. The overall inventory level of lithium carbonate is still high, and there may be a callback risk in the short term. The total market inventory decreased by 2,000 tons to 134,800 tons. Smelter inventory increased by 1,250 tons to 35,000 tons, downstream inventory decreased by 1,000 tons to 60,000 tons, and trader inventory decreased by 2,200 tons to 40,000 tons. Technically, lithium carbonate is in a weak operation, waiting for clarity [9] Industrial Silicon - The industrial silicon futures closed slightly higher and did not follow the strong linkage of coking coal. The spot price continued to be under pressure, and the price of the East China 553 specification decreased by 50 yuan/ton. The release of the复产 capacity in Xinjiang in September and the production increase of large enterprises have increased the risk of inventory accumulation. Large - scale production cuts are expected to start in the southwest at the end of October, and the cost side has strong support. The futures market is expected to remain volatile in the short term [10] Polysilicon - Polysilicon futures continued to rise, mainly driven by the expectation of photovoltaic capacity control policies. The fundamentals do not provide effective support for the time being, and the spot price remains stable. The output in October may continue to grow beyond expectations, and the risk of inventory accumulation under high inventory has increased. After the market, there were rumors about recent capacity policies, which still need to be clarified. The market may have a callback risk due to this, and it is recommended to strictly control positions [11]
