Report Industry Investment Rating No relevant content provided. Core Views - The market is awaiting Powell's speech at the Jackson Hole Central Bank Annual Meeting on Friday to verify the reasonableness of bets on a September interest rate cut. Due to the sharp rebound in the US PPI and the resilience of retail data, there are concerns that Powell may adopt a hawkish stance, leading to cautious trading sentiment. However, the interference with the Fed's independence by Trump's call for Cook to resign has weakened the US dollar and provided a rebound opportunity for precious metals. In the future, the potential for the US to enter a "stagflation-like" situation under tariff shocks supports precious metals, and it is expected that precious metals will continue to trade in a high-range oscillation pattern. [2][3] - For copper, the market focuses on the future interest rate cut rhythm and Powell's speech at the "Global Central Bank Annual Meeting." Domestically, the anti-involution sentiment has subsided, and commodities have generally declined. Fundamentally, the supply of copper ore has been temporarily alleviated, but the increase in LME inventory and the potential inflow of imported goods may put pressure on prices. Demand remains weak, with low restocking enthusiasm from end-users. [5][9] - Alumina's price is reverting to fundamentals as market speculation cools. Although the overall supply-demand situation remains in surplus, short-term supply disruptions due to maintenance plans at some alumina plants may limit price declines. Attention should be paid to the support of the futures price from the expected regression of the basis after it turns positive. [11][13][15] - For electrolytic aluminum, the macro environment is affected by the progress of the Russia-Ukraine issue and the anticipation of Powell's speech at the Jackson Hole meeting. Domestically, the "anti-involution" sentiment is waning. Fundamentally, the increase in aluminum rod production and the decline in aluminum ingot factory inventories have reduced the pressure on social inventory, and low inventory levels may make domestic aluminum prices relatively more resistant to decline compared to the international market. [18][21] - In the case of casting aluminum alloy, the supply is tightening due to the shortage of scrap aluminum, production cuts in some factories, and reduced imports. Demand remains weak, with downstream enterprises mainly engaging in just-in-time procurement. [26][27] - Zinc prices are under pressure due to the continuous increase in domestic supply and weak terminal consumption, leading to a build-up in social inventory. [29][32] - Lead prices are likely to trade in a range due to weak supply and demand. The consumption of lead-acid batteries is sluggish, and the losses of secondary lead smelters are widening, leading to an expansion in production cuts. [35][36][39] - Nickel prices are expected to trade in a wide range due to the large supply surplus and the lack of clear short-term supply-demand contradictions. The increase in refined nickel imports in July did not result in a corresponding increase in domestic inventory, suggesting the accumulation of invisible inventory. [41][42][43] - Stainless steel prices are expected to trade in a wide range, with limited upward momentum due to weak demand and downward support from cost factors. The global economic outlook, tariff policies, and Fed decisions continue to influence the market. [47] - Industrial silicon prices are expected to trade in a range, with the core contradiction being the change in sentiment and fundamental expectations. The market is influenced by the prices of coking coal and polysilicon, and the potential increase in production by leading manufacturers at the end of the month. [50][51][52] - Polysilicon prices are expected to trade in the range of 48,000 - 55,000 yuan/ton. Although the fundamental situation is bearish due to oversupply in August, the price is supported by cost factors. The futures price is recommended to be bought on dips. [54][55][56] - Carbonate lithium prices are expected to rebound after a significant decline. The market overreacted to negative news, but the supply-demand situation may tighten in September due to reduced imports. The price is recommended to be bought after a sufficient correction. [58][60][61] - Tin prices are expected to continue to trade in an oscillatory pattern. The market is in a state of tight balance with weak supply and demand. The supply of tin ore remains tight, and the recovery of production in Myanmar is expected to be delayed until the fourth quarter. [63][65][66] Summary by Directory Precious Metals Market Review - London gold rose 0.94% to $3,347.335 per ounce, and London silver rose 1.44% to $37.855 per ounce. The Shanghai gold and silver futures contracts also closed higher. The US dollar index fell 0.05% to 98.218, the 10-year US Treasury yield declined to 4.2868%, and the RMB exchange rate against the US dollar rose 0.08% to 7.177. [2] Important News - Trump called on Fed Governor Cook to resign, and Cook refused. The Fed's July meeting minutes showed that most officials believed it was appropriate to keep interest rates unchanged, but more officials were open to a September rate cut after the August 1 employment report. The probability of the Fed keeping interest rates unchanged in September is 18.1%, and the probability of a 25-basis-point rate cut is 81.9%. Israel has not responded to the ceasefire proposal from Hamas. [2] Logic Analysis - The market is waiting for Powell's speech at the Jackson Hole meeting. The interference with the Fed's independence has weakened the US dollar and supported precious metals. The potential for the US to enter a "stagflation-like" situation supports precious metals in the future. [3] Trading Strategy - Go long on dips near the 5-day moving average for single positions, and stay on the sidelines for arbitrage and options trading. [3] Copper Market Review - The night session of the SHFE copper 2509 contract closed at 78,730 yuan/ton, up 0.19%, and the LME copper closed at $9,721 per ton, up 0.38%. The LME inventory increased by 1,200 tons to 156,300 tons, and the COMEX inventory increased by 593 tons to 270,500 tons. [5] Important News - The Fed's July meeting minutes showed that almost all policymakers supported keeping interest rates unchanged. Codelco will lower its 2025 production guidance due to an accident at its El Teniente mine. China's imports of copper scrap, copper ore, and refined copper in July showed different trends compared to the previous month and the same period last year. [5][7][8] Logic Analysis - The market focuses on the future interest rate cut rhythm and Powell's speech. Domestically, the anti-involution sentiment has subsided, and commodities have generally declined. Fundamentally, the supply of copper ore has been temporarily alleviated, but the increase in LME inventory and the potential inflow of imported goods may put pressure on prices. Demand remains weak, with low restocking enthusiasm from end-users. [9] Trading Strategy - Copper prices are under pressure due to short-term supply increases. Stay on the sidelines for arbitrage and options trading. [9] Alumina Market Review - The night session of the alumina 2509 contract rose 46 yuan to 3,155 yuan/ton. The spot prices in different regions showed slight changes. [11] Important News - A large aluminum plant in the northwest made a large-scale spot purchase, which led to a slight decline in spot prices. The national alumina production capacity and operating rate increased slightly. The alumina warehouse receipts increased by 2,997 tons to 75,050 tons. Overseas, 30,000 tons of alumina were traded at a price of $369 per ton FOB Australia for September shipment. China's alumina exports and imports in July increased compared to the previous month and the same period last year. The import of bauxite also increased significantly. [11][12][13] Logic Analysis - The market speculation sentiment has cooled, and the price is reverting to fundamentals. The supply-demand situation remains in surplus, but short-term supply disruptions due to maintenance plans at some alumina plants may limit price declines. Attention should be paid to the support of the futures price from the expected regression of the basis after it turns positive. [13][15] Trading Strategy - Alumina prices are expected to trade in a weak oscillatory pattern. Stay on the sidelines for arbitrage and options trading. [16] Electrolytic Aluminum Market Review - The night session of the SHFE aluminum 2509 contract rose 70 yuan to 20,590 yuan/ton. The spot prices in different regions declined. [18] Important News - The Fed's July meeting minutes showed that almost all policymakers supported keeping interest rates unchanged. There are discussions about a potential meeting between Trump, Putin, and Zelensky. The main market electrolytic aluminum inventory decreased by 0.6 tons, and the SHFE warehouse receipts decreased by 2,529 tons to 62,938 tons. A 600,000-ton electrolytic aluminum project in Indonesia has entered the construction phase. China's aluminum ingot imports and exports in July showed different trends compared to the previous month and the same period last year. A project in Inner Mongolia is expected to be completed by the end of the year. [18][19][21] Logic Analysis - The macro environment is affected by the progress of the Russia-Ukraine issue and the anticipation of Powell's speech. Domestically, the "anti-involution" sentiment is waning. Fundamentally, the increase in aluminum rod production and the decline in aluminum ingot factory inventories have reduced the pressure on social inventory, and low inventory levels may make domestic aluminum prices relatively more resistant to decline compared to the international market. [21] Trading Strategy - Aluminum prices are expected to trade in a weak oscillatory pattern in the short term. Consider a long SHFE aluminum and short LME aluminum arbitrage if the Russia-Ukraine issue continues to ease, and exit if the talks are not successful. Pay attention to the widening of the contango when the domestic aluminum ingot social inventory decreases. Stay on the sidelines for options trading. [22] Casting Aluminum Alloy Market Review - The night session of the casting aluminum alloy 2511 contract rose 45 yuan to 20,090 yuan/ton. The spot prices in different regions remained stable. [24] Important News - A policy document may affect the recycling aluminum industry. The weighted average full cost of the Chinese casting aluminum alloy (ADC12) industry in July increased slightly compared to June, and the industry's theoretical profit increased. The social inventory of recycled aluminum alloy ingots in three regions increased slightly. [26] Logic Analysis - The supply is tightening due to the shortage of scrap aluminum, production cuts in some factories, and reduced imports. Demand remains weak, with downstream enterprises mainly engaging in just-in-time procurement. [27] Trading Strategy - Casting aluminum alloy prices are expected to trade in a weak oscillatory pattern. Stay on the sidelines for arbitrage and options trading. [28] Zinc Market Review - The overnight LME zinc market rose 0.58% to $2,786 per ton, and the SHFE zinc 2510 contract rose 0.41% to 22,300 yuan/ton. The spot prices in Shanghai remained stable, and the downstream showed a wait-and-see attitude. [29] Important News - China's zinc concentrate imports in July increased significantly compared to the previous month and the same period last year. The exports of galvanized sheets increased slightly, while the exports of zinc oxide and die-cast zinc alloy decreased significantly. The safety inspections in northern lead-zinc mines have increased, but there is no direct impact on production for now. [29][30][31] Logic Analysis - The continuous increase in domestic supply and weak terminal consumption have led to a build-up in social inventory, putting pressure on zinc prices. [32] Trading Strategy - Pay attention to the domestic social inventory situation. If there is a significant build-up, zinc prices may decline further. Stay on the sidelines for arbitrage and options trading. [33] Lead Market Review - The overnight LME lead market rose 0.33% to $1,980.5 per ton, and the SHFE lead 2510 contract rose 0.18% to 16,775 yuan/ton. The spot price of SMM1 lead declined, and the downstream battery production enterprises mainly made just-in-time purchases. [35] Important News - China's lead-acid battery imports and exports in July showed different trends compared to the previous month and the same period last year. Some secondary lead smelters lowered their purchase prices, but the arrival of scrap lead was not significantly improved. The LME received a registration application for a new lead brand. [35] Logic Analysis - The consumption of lead-acid batteries is sluggish, and the losses of secondary lead smelters are widening, leading to an expansion in production cuts. The supply and demand are both weak, and lead prices are likely to trade in a range. [36][39] Trading Strategy - Trade lead prices in a range by selling high and buying low. Stay on the sidelines for arbitrage and options trading. [39] Nickel Market Review - The overnight LME nickel price fell $15 to $15,045 per ton, and the LME nickel inventory increased by 18 tons to 209,346 tons. The SHFE nickel main contract NI2510 rose 180 yuan to 120,370 yuan/ton. The premiums of different nickel products showed different changes. [41] Important News - The Fed's July meeting minutes showed that only two officials voted against keeping interest rates unchanged. NATO discussed Ukraine's security guarantee issue. The global refined nickel supply was in surplus in June and from January to June. [41][42] Logic Analysis - The large supply surplus limits the upward movement of nickel prices. The increase in refined nickel imports in July did not result in a corresponding increase in domestic inventory, suggesting the accumulation of invisible inventory. The short-term supply-demand situation is balanced, and prices are expected to trade in a wide range. [43][45] Trading Strategy - Sell out-of-the-money put options. [45] Stainless Steel Market Review - The main contract SS2510 remained unchanged at 12,830 yuan/ton. The spot prices of cold-rolled and hot-rolled stainless steel remained stable. [47] Important News - A 600,000-set carbon steel and stainless steel high-end precision casting project started construction. The stainless steel inventory in Foshan decreased slightly. [47] Logic Analysis - The global economic outlook, tariff policies, and Fed decisions continue to influence the market. The concentration of steel mill maintenance in August and the subsequent planned resumptions have increased the sales pressure. The increase in the nickel iron price provides cost support, but the lack of demand limits the upward movement of prices. [47] Trading Strategy - Stainless steel prices are expected to trade in a wide range. Stay on the sidelines for arbitrage. [48] Industrial Silicon Market Review - The industrial silicon futures price declined due to the fall in coking coal and polysilicon prices. The spot prices also decreased. [51] Important News - A new product of a subsidiary of Xin'an Co., Ltd. was included in the list of excellent industrial new products in Zhejiang Province. [51] Logic Analysis - The core contradiction in the industrial silicon market is the change in sentiment and fundamental expectations. The market is influenced by the prices of coking coal and polysilicon, and the potential increase in production by leading manufacturers at the end of the month. The supply and demand situation is relatively balanced, and prices are expected to trade in a range. [52] Trading Strategy - Trade industrial silicon prices in the range of 8,000 - 9,000 yuan/ton by buying on dips near the lower end of the range. Consider a reverse arbitrage between the 11th and 12th contracts. [52] Polysilicon Market Review - The polysilicon futures price fell and then rebounded after the limit-down of lithium carbonate.，The spot prices increased slightly. [54][55] Important News - Trump stated that his government will not approve photovoltaic or wind power projects. [55] Logic Analysis - The polysilicon production in August is expected to be in surplus, but the price is supported by cost factors. The previous low price level provides strong support, and the high price level is limited by the potential large-scale selling for delivery. The futures price is recommended to be bought on dips. [55] Trading Strategy - Buy polysilicon futures on dips in the range of 48,000 - 55,000 yuan/ton. Consider a positive arbitrage between the 2511 and 2512 contracts. Sell out-of-the-money put options and buy call options. [56] Carbonate Lithium Market Review - The carbonate lithium futures price hit the limit-down, and the spot prices remained stable. [58] Important News - A Chilean lithium producer expects an increase in sales in the third quarter and plans to submit an environmental research report for a lithium project next year. The government exposed two cases of tax fraud in the "new three" fields. The retail and wholesale sales of new energy vehicles in August showed growth compared to the same period last year and the previous month. [58][60] Logic Analysis - The sharp decline in carbonate lithium prices was due to market overreaction to negative news and the exit of large funds. However, the supply-demand situation may tighten in

Report Industry Investment Ratings - Not provided in the given content Core Views - Copper: With a downward adjustment in the Fed's rate - cut expectations and a slowdown in the rally of the domestic equity market, the sentiment has weakened slightly. The copper raw material supply remains tight with significant short - term supply disruptions, strongly supporting copper prices. However, the expected increase in supply after the implementation of US copper tariffs poses an upward pressure. Short - term copper prices may oscillate strongly [1]. - Aluminum: The domestic commodity atmosphere is still supported by the "anti - involution" policy expectations, and the tariff's marginal impact remains to be seen. The overall sentiment is neutral. Domestically, aluminum ingot inventories are at a relatively low level, and the rebound in export data indicates strong external demand, firmly supporting aluminum prices. Downstream consumption is weak, and the volatile trade situation exerts pressure. Short - term aluminum prices are likely to oscillate [3]. - Lead: In August, the port inventory of lead ore has increased, and the operating rate of primary lead has recovered. The raw material inventory of secondary lead remains low, and its operating rate is slowly rising. Lead ingot social inventory has increased again. Downstream consumption is under great pressure, and the operating rate of battery enterprises has dropped rapidly. There may be structural disturbances in the LME market, and there is a certain short - term risk of decline [4]. - Zinc: The zinc ore inventory accumulation has slowed down, TC has continued to rise, and the zinc ore supply remains loose. The domestic social inventory of zinc ingots has continued to increase, the smelter's production plan is high, and downstream consumption shows no obvious improvement. The domestic zinc ingot market remains in an oversupply situation. The LME market's structural disturbances are gradually subsiding, and zinc prices still face a large risk of decline [5]. - Tin: The expectation of tin ore supply recovery has strengthened, and the tin ore output is expected to be gradually released in the third and fourth quarters. However, the smelter still faces short - term raw material supply pressure. Domestic consumption in the off - season has been poor, while overseas demand driven by AI computing power has been strong. Short - term supply and demand are both weak, and tin prices are expected to oscillate [6]. - Nickel: The short - term macro - atmosphere is positive, and the prices of stainless steel and nickel - iron have strengthened, driving a slight rebound in nickel prices. However, the improvement in downstream demand is limited, and there is still pressure for price correction [8]. - Lithium Carbonate: The marginal improvement in supply is the focus of the market. News disturbances significantly affect the market sentiment, and the uncertainty of capital games is high. Speculative funds are advised to wait and see cautiously [10][11]. - Alumina: The supply disturbances of domestic and foreign ores continue, which is expected to support ore prices. However, the over - capacity pattern of alumina is difficult to change. After the short - term bullish sentiment in the commodity market fades, it is recommended to short at high levels [13]. - Stainless Steel: The upward movement of stainless steel futures prices is blocked, leading to increased market wait - and - see sentiment and decreased trading activity. Some product prices have slightly declined. The market demand has not shown an obvious recovery, and the market is expected to continue to oscillate in the short term [15]. - Cast Aluminum Alloy: The downstream of cast aluminum alloy is still in the off - season, with weak supply and demand. The cost side provides strong support recently, but the upward price space is relatively limited due to the large difference between futures and spot prices [16].

Group 1: Report Industry Investment Rating - There is no information provided about the report industry investment rating in the content [1] Group 2: Core Viewpoints of the Report - The sentiment trading driven by the "anti - involution" policy in the previous market has subsided, and the bullish sentiment in the alumina futures has significantly declined. The alumina is expected to remain volatile as the short - term contradiction between supply and demand is not significant. The cost of bauxite from Guinea is expected to be firm due to heavy rainfall and unimplemented mine resumption plans. The supply of domestic bauxite in the north may affect local alumina production, while the demand from electrolytic aluminum enterprises is stable [3][9] Group 3: Summary by Relevant Catalogs 1. Transaction Data - From August 1st to August 8th, 2025, the alumina futures (active) rose from 3162 yuan/ton to 3170 yuan/ton; the domestic alumina spot price rose from 3274 yuan/ton to 3275 yuan/ton; the spot premium increased by 42 yuan/ton to 115 yuan/ton; the Australian alumina FOB decreased from 377 dollars/ton to 373 dollars/ton; the import profit and loss improved by 30.6 yuan/ton to - 31.34 yuan/ton. The exchange warehouse inventory increased by 19567 tons to 26182 tons, and the exchange factory warehouse remained at 0 tons [4] 2. Market Review - Alumina futures rose 0.25% last week, closing at 3170 yuan/ton, while the national weighted average price of the spot market was 3275 yuan/ton, up 1 yuan/ton from the previous week. In the bauxite market, domestic ore prices were stable overall, with low mine operating rates in the north due to policy and flood season factors, and relatively stable southern ores. Imported ore prices are expected to be firm due to government actions and weather - related impacts in Guinea. On the supply side, there was a regional supply - demand mismatch in the alumina market. On the consumption side, the operating capacity of the electrolytic aluminum industry increased slightly [5][6] 3. Market Outlook - The event of the Guinea government taking over GAC's mining rights has little short - term impact on supply but indicates a long - term tightening of mining rights. The alumina production capacity has both increases and decreases, with the overall operating capacity increasing slightly. The electrolytic aluminum capacity is stable, and the procurement of raw materials is stable. The spot price is stable, and the futures bullish sentiment has declined. Alumina is expected to remain volatile in the short term [3][9] 4. Industry News - On August 4th, the Guinea government established Nimba Mining Company SA to take over EGA - GAC's mining rights. The AXIS mining area has not resumed production. A Shanxi alumina enterprise has reduced production due to ore issues, and a Guizhou enterprise's roasting furnace maintenance has ended [10] 5.

Report Industry Investment Ratings Not provided in the content. Core Views of the Report - The overall market is influenced by multiple factors including geopolitical events, economic data, and policy changes. For instance, the potential outcomes of the US-Russia talks and the uncertainty in the US-China trade relationship are key factors affecting various markets [17][44]. - In the financial market, different asset classes have different outlooks. Gold is expected to continue its oscillatory trend with increased volatility; the US dollar is predicted to remain weak in the short - term; and the US stock market may face correction risks due to the fluctuating interest - rate cut expectations [13][18][22]. - In the commodity market, each sector has its own supply - demand dynamics. For example, the油脂 market may experience short - term pullbacks but has long - term potential for long - positions; the copper market is likely to have high - level oscillations with inventory increases limiting the upside [33][57]. Summary by Directory 1. Financial News and Reviews 1.1 Macro Strategy (Gold) - Fed's Bowman supports three interest rate cuts this year. The gold price oscillated on Friday with increased intraday volatility. After the White House clarified that imported gold bars would not be taxed, the COMEX gold price declined to narrow the spread with London gold. The gold price is in an oscillatory range, and short - term oscillations are expected to continue with attention to correction risks [12][13]. 1.2 Macro Strategy (Foreign Exchange Futures - US Dollar Index) - The NATO Secretary - General is optimistic about the "Trump - Putin meeting". Nordic and Baltic leaders reaffirmed their support for Ukraine. The US - Russia meeting in Alaska and the European stance on Ukraine make the outcome of the meeting and the cease - fire in the Russia - Ukraine conflict highly uncertain, leading to the US dollar remaining weak in the short - term [14][15][17]. 1.3 Macro Strategy (US Stock Index Futures) - Fed officials have different views on interest rates. Some support maintaining the current rate due to unmet inflation targets, while others advocate for rate cuts. The market's interest - rate cut expectations are volatile, and the US stock market at its current level may face correction risks [19][21][22]. 1.4 Macro Strategy (Treasury Bond Futures) - The issuance of local bonds with VAT on interest started on August 8. The central bank conducted reverse repurchase operations. The bond market is expected to be in a favorable period in the first half of August, and trading - position long - holders can continue to hold their positions [23][24][27]. 1.5 Macro Strategy (Stock Index Futures) - In July, China's CPI was flat year - on - year, and PPI decreased by 3.6% year - on - year. Beijing optimized its housing purchase restrictions, and the capital market is expected not to have a large - scale IPO expansion. The strengthening of the core CPI may support the stock market pricing, and it is recommended to allocate evenly among stock indices [28][29][31]. 2. Commodity News and Reviews 2.1 Agricultural Products (Soybean Oil/Rapeseed Oil/Palm Oil) - The actual soybean crushing volume in the 32nd week was 2177500 tons, and the expected volume in the 33rd week is 2369500 tons. Multiple countries' policies may change. India may raise edible oil import tariffs, and there are rumors about the US RVO proposal. The short - term oil market may pull back, but it has long - term potential for long - positions, and it is recommended to go long on dips [32][33]. 2.2 Agricultural Products (Soybean Meal) - The market expects the USDA August supply - demand report to raise the US soybean yield. The US soybean market is weak, while the domestic soybean meal market is relatively strong. It is recommended to continue to focus on the development of Sino - US relations and changes in import and demand [34][35]. 2.3 Agricultural Products (Sugar) - Brazil's sugar exports decreased in July, indicating weak export demand. The international sugar market is under pressure due to the expected oversupply in the 25/26 season. However, factors such as the low sugar - ethanol price difference and poor cane quality may limit the downside of the ICE raw sugar price. The domestic sugar market is also under pressure from increased imports, but the downside of the Zhengzhou sugar price is limited, and it is not recommended to short aggressively [39][40]. 2.4 Agricultural Products (Cotton) - The US tariff policy and the uncertainty in the US - China trade relationship increase market concerns. The ICE cotton price is expected to remain weak in the short - term. Domestically, the cotton supply is tight before the new cotton harvest, and there may be a small - scale "rush to buy" at the beginning of the new cotton season. The 1 - month contract may rebound, and it is recommended to pay attention to the US - China trade policy [44]. 2.5 Black Metals (Rebar/Hot - Rolled Coil) - China has completed the ultra - low emission transformation of 600 million tons of crude steel production capacity. The inventory of five major steel products is increasing, and the demand has not changed significantly. The steel price is expected to oscillate in the short - term due to the limited impact of environmental protection restrictions on supply and the difficulty of the spot price to follow the increase [45][47]. 2.6 Agricultural Products (Corn Starch) - The cassava starch inventory has increased again at a high level, and the price difference with corn starch has narrowed. There is no driving force for the price difference to strengthen in the supply - demand situation, and the price difference in the 09 contract may be affected by the new corn harvest in North China [48]. 2.7 Agricultural Products (Corn) - The成交 rate of imported corn auctions remains low. The market's demand for imported corn substitutes is expected to decline, and the old - crop spot price is likely to weaken. It is recommended to hold short positions in new - crop corn and pay attention to the weather [49][50]. 2.8 Non - ferrous Metals (Alumina) - Two factories of a Shanxi alumina enterprise were affected by ore supply. The spot price remained stable, and the futures price was weak. It is recommended to wait and see [51][53]. 2.9 Non - ferrous Metals (Copper) - The US is interested in investing in Pakistan's copper mining. Chile's Codelco partially restarted a copper mine. Macro factors may provide short - term support for the copper price, but the increase in global inventory will limit the upside. It is recommended to wait and see for single - side trading and focus on the cross - market reverse arbitrage strategy [54][57]. 2.10 Non - ferrous Metals (Polysilicon) - The Guangzhou Futures Exchange added new registered brands for polysilicon futures. The spot trading is light, and the inventory is increasing. The short - term polysilicon price may range between 45000 - 57000 yuan/ton, and it may reach over 60000 yuan/ton in the long - term. It is recommended to go long on dips and consider the 9 - 12 positive arbitrage [58][60]. 2.11 Non - ferrous Metals (Industrial Silicon) - Some production capacities in Xinjiang have resumed production. The supply may increase in August, but the demand from polysilicon may lead to inventory reduction. It is recommended to go long on dips in the short - term, with risks from large - factory resumption and polysilicon production cuts [61][62]. 2.12 Non - ferrous Metals (Lithium Carbonate) - Ningde Times' Jiaxiaowo mining site will stop production. The production loss will lead to inventory reduction in the third - quarter balance sheet. The short - term price is expected to be strong, and it is recommended to go long on dips and consider the inter - month positive arbitrage [63]. 2.13 Non - ferrous Metals (Lead) - The primary lead production is expected to increase, while the secondary lead production is affected by sewage inspections. The demand is in the pre - peak season waiting to be verified. It is recommended to hold long positions established at low prices and pay attention to the positive arbitrage between domestic and foreign markets [65][66]. 2.14 Non - ferrous Metals (Zinc) - The LME zinc inventory has decreased significantly, while the domestic zinc supply is high. The demand is stable in the primary processing sector. The short - term trading of Shanghai zinc is difficult, and it is recommended to manage positions for single - side trading, consider the medium - term positive arbitrage, and wait and see for the domestic - foreign trading [67][68]. 2.15 Non - ferrous Metals (Nickel) - The LME nickel inventory has increased. The macro - environment provides some support, but the supply is expected to be in surplus. The short - term nickel price is unlikely to decline significantly, and it is recommended to focus on short - term trading opportunities and consider short - selling at high prices in the medium - term [69][70]. 2.16 Energy Chemicals (Carbon Emissions) - The EU carbon price oscillated last week. The carbon price may be supported by the buying demand before the compliance deadline, but the weak demand may limit the upside. The EU carbon price is expected to oscillate in the short - term [71][72]. 2.17 Energy Chemicals (Crude Oil) - The US oil rig count decreased. India's state - owned refineries are招标 to purchase non - Russian crude oil. The oil price has fallen to a new low since early June due to reduced geopolitical risk premiums. The short - term oil price volatility is expected to increase [73][74][76]. 2.18 Energy Chemicals (Caustic Soda) - The Shandong caustic soda market is stable. The supply has decreased slightly, and the demand is average. The caustic soda spot price is starting to weaken, but the downside is limited due to factors such as low liquid chlorine prices and strong coal prices [77][78]. 2.19 Energy Chemicals (Pulp) - The imported wood pulp spot market has limited adjustments. The futures price is oscillating. The anti - involution sentiment has cooled down, and the pulp market is expected to be weak and oscillatory in the short - term [79]. 2.20 Energy Chemicals (PVC) - The domestic PVC powder market is weakly oscillating. The futures price is down, and the trading is light. The PVC fundamentals are weak, but the macro - environment and coal prices provide support. The market is expected to oscillate [80]. 2.21 Energy Chemicals (PX) - A South Korean PX plant is under maintenance, and Japanese PX plants are restarting. The PX price is affected by downstream demand, PTA spot price, and other factors, and is expected to oscillate in the short - term [81]. 2.22 Energy Chemicals (PTA) - A Northeast PTA plant is shutting down. The weaving industry is in the off - season, and the PTA supply and demand have little contradiction. The PTA price mainly follows the crude oil price and is expected to oscillate in the short - term [82][83]. 2.23 Shipping Index (Container Freight Rate) - Maersk's second - quarter earnings were strong. The SCFI index has declined. The shipping companies are accelerating price cuts, and the supply pressure is increasing. The freight rate may continue to decline, and it is recommended to pay attention to the short - selling opportunities when the market is boosted by sentiment [84][87].

Report Industry Investment Rating - Alumina: Oscillating [4] Core View of the Report - The alumina futures price is expected to show an oscillating and weakening trend. The supply of alumina has turned to a slight surplus with the release of复产 and new production capacity, and the continuous generation of warehouse receipts exerts significant pressure on the futures price [14]. Summary by Relevant Catalogs 1. Alumina Industry Chain Weekly Overview Raw Materials - Domestic ore prices remained stable last week. The含税 price of 58/5 ore in Shanxi was 700 yuan/ton, in Henan was 658 yuan/ton, and the arrival含税 price of 60/6 bauxite in Guizhou was 596 yuan/ton. Continuous rainfall in core bauxite - producing areas increased the difficulty of mine operation and ore transportation, causing raw material supply shortages for some alumina enterprises [1][11]. - The price index of Guinea ore (45/3) remained in the range of 73 - 75 US dollars/dry ton. The shipping volume from Guinea in July was about 11 million wet tons, and the impact of the decline in shipping on the supply side will be reflected in August, September, and October. The Guinean government revoked the memorandum of understanding with Shunda Mining, halting production and shipping again. Miners' willingness to support prices strengthened, but downstream buyers were not interested in purchasing. During the period, 4.813 million tons of new ore arrived, including 3.818 million tons from Guinea and 0.885 million tons from Australia. The Cape ship freight from Guinea to China remained at 23.5 - 24 US dollars/ton [1][11]. Alumina - Alumina spot prices rose last week.
