1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - This week, the high - sulfur crack spread rebounded, the monthly spread rebounded from a low level, and the basis rebounded. The European high - sulfur crack spread fluctuated, the monthly spread weakened, and the EW continued to strengthen. The 0.5% crack spread in Singapore weakened, the monthly spread fluctuated at a low level, and the basis fluctuated at a low level. The European V low - sulfur crack spread fluctuated at a low level [3]. - In terms of inventory, Singapore's residual oil inventory decreased, high - sulfur floating storage inventory increased, ARA's residual oil inventory remained basically flat, Fujairah's residual oil inventory decreased significantly, high - sulfur floating storage inventory decreased, and EIA's residual oil inventory increased slightly [3]. - This week, the crack spreads of gasoline and diesel in the external market continued to decline, and the price difference between low - sulfur fuel oil and diesel continued to rebound. After the Al Zour refinery shut down due to a fire on October 21, the external low - sulfur fuel oil market faced support, but the short - term upward space was limited [4]. - The global residual oil market entered the off - season for inventory accumulation. The external crack spreads should pay attention to crude oil price fluctuations and feedstock premium/discount levels. This week, the external market's inventory decreased and the monthly spread strengthened, and it remained volatile in the short term. The valuation of low - sulfur fuel oil was low, but there was no driving force [4]. 3.

Report Industry Investment Rating There is no information provided regarding the report industry investment rating. Core Viewpoints of the Report - Geopolitical factors such as the situations in Venezuela, Russia - Ukraine, and the Middle East are continuously disturbing the crude oil market, causing oil prices to fluctuate. Different raw materials have varying impacts on downstream chemical products. The market has entered an expectation - trading phase dominated by funds, with extreme price differences among some varieties, and there is a possibility of reverse fluctuations due to capital disturbances. The inventories of three major liquefied chemical products (EB, BZ, and EG) have all increased on a month - on - month basis [2][3]. Summary by Relevant Catalogs 1. Market Overview - Geopolitical factors are disturbing the crude oil market, including the US's intensified blockade of Venezuela, the key stage of Russia - Ukraine peace negotiations, and potential Israeli attacks on Iran. Coal inventories are high due to lower - than - expected seasonal demand. The different performances of raw materials have implications for downstream chemical products [2]. - After the main contracts shifted to the 05 contracts, the market entered an expectation - trading phase dominated by funds. Polyolefins are considered for short - selling, while PX is favored for long - buying. The inventories of EB, BZ, and EG have all increased, with BZ inventory increasing by 5% month - on - month, and BZ and EB port inventories at a five - year high, and EG inventory approaching the five - year median [3]. 2. Performance of Each Variety Crude Oil - **Viewpoint**: Geopolitical factors in Venezuela, Russia - Ukraine, and other regions continue to disturb the market, and oil prices continue to fluctuate. - **Main Logic**: Overseas refined oil inventories are accumulating rapidly, and the pressure of crude oil inventory is mainly reflected in floating storage. The supply - surplus situation persists. Geopolitical factors dominate short - term price fluctuations, and there is a phased support of geopolitical premium near the annual low [4][8]. - **Outlook**: The supply - surplus pattern continues, and geopolitical expectations are unstable. Oil prices are expected to fluctuate near the annual low in the short term [8]. Bitumen - **Viewpoint**: The situation between the US and Venezuela has heated up again, and bitumen futures prices have risen. - **Main Logic**: OPEC+ is increasing production in December, and there is still a possibility of a Russia - Ukraine agreement. The situation between the US and Venezuela has driven up bitumen futures prices. If there is a substantial supply disruption, bitumen futures prices will be strong; otherwise, they may fall after rising. The pricing of bitumen futures has returned to Shandong spot prices, and the high valuation of bitumen is being revised downward. Bitumen is in a situation of weak supply and demand, and there is still great pressure on inventory accumulation [9]. - **Outlook**: The absolute price of bitumen is overvalued [9]. High - Sulfur Fuel Oil - **Viewpoint**: Geopolitical factors have driven up the futures prices of high - sulfur fuel oil. - **Main Logic**: OPEC+ is increasing production in December, and there is still a possibility of a Russia - Ukraine agreement. Tensions between the US and Venezuela have led to a rebound in high - sulfur fuel oil. However, the demand for high - sulfur fuel oil is currently suppressed by high floating storage in the Asia - Pacific region. The three driving forces for high - sulfur fuel oil (Russia - Ukraine conflict, refinery procurement, and Palestine - Israel conflict) are currently weak, and fuel oil demand is still weak [9]. - **Outlook**: Supply and demand are weak [9]. Low - Sulfur Fuel Oil - **Viewpoint**: Low - sulfur fuel oil follows the rise of crude oil. - **Main Logic**: Low - sulfur fuel oil follows the trend of crude oil. It has strong product attributes but faces negative factors such as a decline in shipping demand, green energy substitution, and high - sulfur substitution. Its valuation is low and is expected to fluctuate with crude oil. Domestically, the pressure on refined oil supply is increasing, which may be transmitted to low - sulfur fuel oil, resulting in an increase in supply and a decline in demand. Overseas, unexpected maintenance and unstable operation of some refineries have led to an unexpected decline in supply and an increase in valuation [11]. - **Outlook**: Low - sulfur fuel oil is affected by green fuel substitution and insufficient high - sulfur substitution demand space, but its current valuation is low and it will fluctuate with crude oil [11]. Methanol - **Viewpoint**: The situation in coastal and inland areas is relatively stalemate, and methanol is expected to fluctuate. - **Main Logic**: The inland market is weak, with high freight rates and general downstream follow - up. Although Iranian imports are expected to decrease in the long term, coastal port inventories are still at a historical high, and the arrival volume may be high in the short term. The trading logic in coastal areas is unclear, and the unloading rhythm of arriving ships may be a key variable [30]. - **Outlook**: It is expected to fluctuate widely in the short term [30]. Urea - **Viewpoint**: Both supply and demand are weak, and the futures market fluctuates and consolidates. - **Main Logic**: On December 22, 2025, the urea supply was affected by gas restrictions and maintenance, and the operating rate fell below 80%. However, due to the new production capacity put into operation throughout the year, the daily output was still above 190,000 tons, maintaining pressure on the market. On the demand side, there is still support from off - season storage, compound fertilizer procurement, and export port collection, but the downstream's acceptance of the increased price is low, and the actual follow - up is cautious [31]. - **Outlook**: The short - term market is expected to fluctuate and may weaken. Attention should be paid to the inventory reduction of enterprises, the progress of off - season storage, and the operating rate of compound fertilizer factories [31]. Ethylene Glycol (EG) - **Viewpoint**: There is still room for an increase in the load, and the spot circulation remains loose. - **Main Logic**: With the restart of some devices, the supply has increased again, and there are expectations of increased production from other devices. The overall spot circulation of ethylene glycol remains loose, and the inventory accumulation period is expected to last until February. The market sentiment needs time to recover, and the price is expected to fluctuate within a range [22][24]. - **Outlook**: The price will fluctuate within a range in the short term, and the long - term inventory pressure is still large, so the rebound height is limited [24]. PX - **Viewpoint**: Boosted by sentiment, PX maintains a strong consolidation, and profits continue to expand. - **Main Logic**: The market is optimistic about the medium - and long - term pattern of PX, and bullish funds continue to bet. Geopolitical factors have driven up oil prices, and the resonance of cost and sentiment has led to the continued rise of PX and the expansion of PXN. Currently, the industrial chain profits are overly concentrated upstream, squeezing the cash flow of PTA and polyester. Attention should be paid to whether there will be unexpected production cuts or early holidays in the polyester industry [13][14]. - **Outlook**: PX is expected to consolidate strongly under the influence of expectations and market sentiment. PXN is expected to fluctuate within the range of [300, 380] US dollars per ton. The positive spread logic of PX remains [14]. PTA - **Viewpoint**: With cost support, the outlook is positive, and the processing margin on the futures market has been significantly repaired. - **Main Logic**: The upstream PX is still strong, providing cost support for PTA. The supply - demand pattern of PTA is still tight, and the export data in November was good, boosting market confidence. The BIS certification cancellation has a continuous positive impact, and it is expected that the export performance in December will still improve. PTA is expected to maintain a de - stocking pattern, and the seasonal inventory accumulation in January - February is less than in previous years. The price is expected to fluctuate strongly following the raw materials [14][15]. - **Outlook**: The price will fluctuate strongly following the cost, and the processing margin will operate within a range with limited expansion space. It is recommended to go long on the TA05 contract at low prices and take profit at around 5100. A positive spread strategy can be adopted for TA05 - 09 [15]. Short - Fiber - **Viewpoint**: The upstream cost support has strengthened, but the cost cannot be fully passed on, and the profit is compressed. - **Main Logic**: The upstream polyester raw materials are rising, providing cost support for polyester short - fiber. However, the downstream's willingness to accept high prices is low, resulting in poor sales of polyester short - fiber. The cost cannot be fully passed on, and the profit is compressed due to the off - season expectation [25][26]. - **Outlook**: The price of short - fiber will fluctuate with the upstream, and the support for the processing margin has increased. The position of going long on TA and shorting PF should be closed for profit [26]. Bottle Chip - **Viewpoint**: The upstream raw material cost supports the price. - **Main Logic**: The upstream raw material futures have risen strongly, and polyester bottle - chip factories have mostly raised their prices. The trading volume in the polyester bottle - chip market is acceptable. In the short term, the price will fluctuate strongly following the raw materials [27]. - **Outlook**: The absolute price will fluctuate with the raw materials, and the overall support for the processing margin has increased [27]. Propylene (PL) - **Viewpoint**: The spot is strong, and the expectation of PDH maintenance supports PL to fluctuate. - **Main Logic**: The expectation of PDH maintenance still provides support. On the spot side, the inventory of propylene enterprises is controllable, and the offer is stable, with only a few prices slightly adjusted downward. The downstream buying is cautious, and there is no significant change in trading. In the short term, the profit of powder is under pressure, and the decline in the operating rate has a negative impact [35]. - **Outlook**: PL is expected to fluctuate in the short term [35]. PP - **Viewpoint**: The expectation of maintenance supports PP to fluctuate. - **Main Logic**: The profit of PDH is under short - term pressure, and the valuation support of gas - based refineries has increased, with a strong expectation of increased maintenance. Geopolitical factors affect the short - term price of oil, and there is a phased support of geopolitical premium near the annual low, but there is still great downward pressure in the next quarter. The downstream of PP is in the off - season, and the purchasing mentality is cautious. The current trading of maintenance is mainly focused on the expectation for January 2026, and the actual supply pressure is still large, with high inventory [34]. - **Outlook**: PP is expected to fluctuate in the short term [34]. Plastic (LLDPE) - **Viewpoint**: The support of maintenance is limited, and plastic fluctuates weakly. - **Main Logic**: The oil price fluctuates, and geopolitical factors affect the short - term price. There is a phased support of geopolitical premium near the annual low, but there is great downward pressure in the next quarter. The fundamental support of plastic itself is still limited, with limited pressure on the profits of oil, coal, and ethane production, and a weaker expectation of supply reduction compared to PP. The upstream and mid - stream still have the intention to reduce inventory at high prices, which will suppress the price. The overall demand for plastic is entering the off - season, and the sustainability of the short - term increase in downstream trading volume is questionable [33]. - **Outlook**: Plastic is expected to fluctuate weakly in the short term [33]. Styrene - **Viewpoint**: New export transactions and a strong aromatic atmosphere have led to the intraday rise of styrene. - **Main Logic**: Recently, styrene has been fluctuating weakly. The downstream ABS has shown negative feedback, with some enterprises reducing their loads. The liquidity of styrene has increased, and the basis and profit have weakened. In the short term, the support comes from the external pure benzene, while the upper limit is restricted by the pure benzene inventory pressure and the shift of styrene to inventory accumulation [20][21]. - **Outlook**: Styrene is about to shift to inventory accumulation, and the upstream has difficulty in reducing inventory and still faces great pressure. The upper limit is obvious, and export transactions will stimulate short - term rebounds [21]. PVC - **Viewpoint**: There is insufficient driving force, and the futures market fluctuates. - **Main Logic**: At the macro level, the short - term emotional boost of the "anti - involution" policy on low - valuation varieties needs to be observed for implementation. At the micro level, the supply - demand situation of PVC has improved marginally due to overseas capacity withdrawal and domestic marginal enterprise production cuts, but the over - supply expectation cannot be reversed. The domestic production may remain stable, the downstream operating rate is seasonally weak, the export orders are good this week, and the calcium carbide price is under pressure [37]. - **Outlook**: The de - stocking driven by production cuts will probably limit the rebound space of PVC. The over - supply situation cannot be reversed in the medium term, and the futures market is expected to fluctuate [37]. Caustic Soda - **Viewpoint**: With low valuation and weak expectation, caustic soda may fluctuate. - **Main Logic**: At the macro level, the short - term emotional boost of the "anti - involution" policy on low - valuation varieties needs to be observed for implementation. At the micro level, although the short - term de - stocking in Shandong has occurred, if the alumina production is reduced and the upstream maintains a high operating rate, the supply - demand of caustic soda will still be in excess. The profit of marginal alumina devices is poor, the inventory of Weiquan is high, the demand for caustic soda will be boosted by the new alumina project in Guangxi in Q1 2026, the non - aluminum operating rate is weak, and the downstream's willingness to replenish inventory is low [39][40]. - **Outlook**: The market sentiment is positive in the short term, and the upstream in Shandong is de - stocking. However, the supply - demand is under pressure in the long term, and the market may wait and see [40]. 3. Variety Data Monitoring Energy and Chemical Daily Indicator Monitoring - **Inter - period Spread**: The inter - period spreads of various varieties have changed. For example, the 1 - 5 month spread of PX decreased by 86 yuan per ton, and the 5 - 9 month spread of PP decreased by 15 yuan per ton [42]. - **Basis and Warehouse Receipts**: The basis and warehouse receipts of different varieties also show different changes. For example, the basis of bitumen decreased by 76 yuan per ton, and the warehouse receipt was 54,100 lots [43]. - **Inter - variety Spread**: The inter - variety spreads have also changed. For example, the 1 - month spread of PP - 3MA decreased by 104 yuan per ton, and the 1 - month spread of TA - EG increased by 157 yuan per ton [45]. Chemical Basis and Spread Monitoring There is no specific content provided in the given text for in - depth analysis of this part. 4. Commodity Index - The comprehensive index, specialty index, and sector index of the commodity index all showed different degrees of increase on December 22, 2025. The comprehensive index increased by 1.10%, the commodity 20 index increased by 1.34%, and the industrial products index increased by 0.79%. The energy index increased by 2.32% on the day, 1.47% in the past 5 days, decreased by 2.08% in the past month, and decreased by 10.72% since the beginning of the year [284][285].

1. Report Industry Investment Ratings - Crude Oil: Cautiously bearish [1] - LPG: Cautiously bearish [1] - L: Bearish continuation [1] - PP: Bearish continuation [1] - PVC: Bearish continuation [1] - PX/PTA: Cautiously chase up [3] - Ethylene Glycol: Short on rebound [3] - Methanol: Cautiously chase up [3] - Urea: Oscillate weakly [3] - Natural Gas: Cautiously bearish [6] - Asphalt: Bearish rebound [6] - Glass: Bearish consolidation [6] - Soda Ash: Bearish consolidation [6] 2. Core Views of the Report - The report analyzes various energy and chemical products, considering factors such as geopolitical uncertainties, supply - demand imbalances, cost fluctuations, and inventory levels. It provides investment suggestions for each product based on their specific market conditions [1][3][6]. 3. Summary by Product Crude Oil - **Core View**: Cautiously bearish. Geopolitical uncertainties and supply surplus pull the oil price, which oscillates weakly. - **Main Logic**: Geopolitical factors include the easing of the Russia - Ukraine conflict and rising uncertainties in South America. The core driver is the supply surplus in the off - season, with increasing global floating storage and on - the - way crude, and rising inventories in the US. Key variables to watch are US shale oil production and geopolitical developments in Russia - Ukraine and South America [1][9]. - **Strategy**: Add short positions. Focus on SC in the range of [420 - 435] [11]. LPG - **Core View**: Cautiously bearish. - **Main Logic**: The cost - end oil price rebounds in the short - term but is under pressure in the long - term. On the supply - demand side, refinery operations increase, and downstream chemical demand is resilient. Inventory is favorable, with port and in - plant inventories decreasing [1][15]. - **Strategy**: Hold short positions. Focus on PG in the range of [4050 - 4150] [16]. L - **Core View**: Bearish continuation. - **Main Logic**: Supply elasticity is insufficient, and the basis is continuously weak. The fundamentals show weak supply and demand, with low shutdown ratios and insufficient maintenance. The peak season for shed films is ending, and enterprise inventories are increasing slightly, facing de - stocking pressure [1][20]. - **Strategy**: Partially close short positions in the short - term. Wait for a rebound to go short in the long - term. Hold short positions on the LP05 spread. Focus on L in the range of [6250 - 6400] [20]. PP - **Core View**: Bearish continuation. - **Main Logic**: The total commercial inventory is at a high level compared to the same period. In December, the demand enters the off - season, and the shutdown ratio drops. The PDH profit is compressed, increasing the expectation of maintenance. - **Strategy**: Reduce short positions. Wait for a rebound to go short in the long - term. Short the MTO05 spread. Focus on PP in the range of [6150 - 6300] [24]. PVC - **Core View**: Bearish continuation. - **Main Logic**: High inventory and high premium structure limit the rebound space. Although overseas device shutdowns and maintenance support exports, the current upstream and mid - stream inventories are high, and supply reduction is insufficient. Recently, both chlorine and alkali prices have fallen, and some marginal devices are reducing loads [1][27]. - **Strategy**: Close short - term long positions. Wait for continuous inventory reduction to go long on dips in the long - term. Industrial customers should hedge at high prices. Focus on V in the range of [4550 - 4650] [27]. PX/PTA - **Core View**: Cautiously chase up. - **Main Logic**: The supply side has a slight reduction in load, with significant maintenance of PTA devices. Downstream demand is relatively good but expected to weaken. The cost end provides support. In the short - term, the fundamentals are healthy, but there is an expectation of inventory accumulation in January [3][29]. - **Strategy**: Pay attention to the opportunity to buy on dips for the 05 contract. Focus on TA in the range of [4880 - 5010] [30]. Ethylene Glycol - **Core View**: Short on rebound. - **Main Logic**: Domestic ethylene glycol device operation loads increase, and overseas devices change little. Downstream demand is relatively good but expected to weaken. Port inventories are rising, and there is an expectation of inventory accumulation in December. The valuation is low, but there is no upward driver [3][32]. - **Strategy**: Look for opportunities to short on rebounds. Focus on EG05 in the range of [3710 - 3770] [33]. Methanol - **Core View**: Cautiously chase up. - **Main Logic**: Taicang spot prices weaken slightly, and the negative basis strengthens. Port inventories are decreasing, while social inventories are increasing. The supply side has relatively good profits for coal/coke oven gas processes, and domestic device operation loads are at a high level. Overseas devices have a slight reduction in load. The demand side weakens slightly, and coal - based costs are expected to strengthen [3][36]. - **Strategy**: Do not chase the rally. Look for opportunities to buy on dips for the 05 contract. Focus on MA05 in the range of [2131 - 2181] [38]. Urea - **Core View**: Oscillate weakly. - **Main Logic**: The spot price of small - particle urea in Shandong stabilizes. The supply pressure is expected to increase in late December as some devices resume production. The demand is expected to weaken, and the inventory is at a relatively high level. However, the domestic and overseas arbitrage window is not closed [3][40]. - **Strategy**: Look for opportunities to go long on dips for the 05 contract. Focus on UR05 in the range of [1660 - 1700] [42]. Natural Gas - **Core View**: Cautiously bearish. - **Main Logic**: The shutdown of a production line at the US Freeport and relatively mild recent temperatures put pressure on gas prices. Supply increases as US exports decrease, and demand support weakens due to mild weather [6][45]. - **Strategy**: Focus on NG in the range of [3.895 - 4.260] [45]. Asphalt - **Core View**: Bearish rebound. - **Main Logic**: The price is mainly anchored to the cost - end oil price, which is weak. The supply and demand are both weak, but recent South American geopolitical uncertainties cause a short - term price rebound [6][48]. - **Strategy**: Partially close short positions. Focus on BU in the range of [2900 - 3000] [49]. Glass - **Core View**: Bearish consolidation. - **Main Logic**: The in - plant inventory ends a three - week decline. High inventory limits the rebound space. The production line is stable, and the three - process profits turn negative. Real estate volume and prices are in an adjustment period [6][52]. - **Strategy**: Partially close short positions in the short - term. Wait for a rebound to go short in the long - term. Focus on FG in the range of [1020 - 1060] [52]. Soda Ash - **Core View**: Bearish consolidation. - **Main Logic**: The number of warehouse receipts increases, and the in - plant inventory ends a five - week high - level decline. Although maintenance eases short - term supply pressure, the planned commissioning of a 2.8 - million - tonne device at Yuanxing in late December will keep the long - term supply loose. The demand support from the glass industry is insufficient [6][56]. - **Strategy**: Partially close short positions. Wait for a rebound to go short in the long - term. Focus on SA in the range of [1150 - 1200] [56].

1. Report Industry Investment Ratings - There is no information about industry investment ratings in the provided reports [1][4][7][8] 2. Core Views of the Reports Steel Industry - The overall steel market is expected to maintain a range - bound trend. Rebar is predicted to stay within the 3000 - 3200 range, and hot - rolled coils within the 3150 - 3350 range. The 1 - 5 positive spread of rebar can be held, the 5 - month hot - rolled coil to rebar spread should be exited at low levels, and long positions in the rebar - to - iron ore ratio can be considered at low levels [1] Iron Ore Industry - Iron ore prices are expected to maintain a range - bound trend, with the range of 730 - 820. It is recommended to operate within the range for the 05 contract and try short - selling around 800 [4] Coke and Coking Coal Industry - For coke, short - term rebound expectations exist. It is advisable to go long on the coke 2605 contract at low prices and adopt the strategy of long coking coal and short coke. For coking coal, short - term rebound expectations also exist, and it is recommended to go long on the coking coal 2605 contract at low prices with the same long - short strategy [7] Ferrosilicon and Ferromanganese Industry - Ferrosilicon prices are expected to be range - bound between 5400 - 5650. It is recommended to try short - selling when the price rebounds above the spot cost in Ningxia. Ferromanganese is expected to move weakly in the short term, and the price decline is limited [8] 3. Summaries According to Relevant Catalogs Steel Industry - **Prices and Spreads**: Rebar and hot - rolled coil spot prices in some regions decreased, and futures prices also declined.

Core Views of the Reports - **Natural Rubber**: With geopolitical tensions affecting supply in Thailand and domestic产区 entering the off - season, there is support at the bottom of rubber prices. However, due to high production and sales pressure and the seasonal demand slump, the market is weak. Rubber prices are expected to fluctuate widely between 15,000 - 15,500 yuan/ton [1]. - **Glass and Soda Ash**: For soda ash, the supply may increase with the potential output from new projects, and demand is shrinking, so the price is expected to continue to decline with occasional technical rebounds. For glass, the spot price is stable but facing weakening demand in the north and high inventory in the middle - stream, so the futures price may be under pressure and continue to oscillate at the bottom [3]. - **PVC and Caustic Soda**: The caustic soda industry still has supply - demand pressure, and prices are expected to be weak. The PVC market is affected by high supply, low demand, and cost pressure, and is expected to maintain range - bound trading and then weaken after a rebound [4]. - **Polyolefins**: The market is trading on the expectation of high production in 2026 and weak current conditions. Both PE and PP are facing downward pressure on prices, with the price center expected to decline further [6]. - **Methanol**: Although the port may face inventory accumulation in December, there is an expected shift to inventory reduction in the first quarter of the next year. The inland market is expected to be stable with prices fluctuating slightly [10]. - **Pure Benzene and Styrene**: The short - term driving force for pure benzene is weak due to weak downstream demand and cost support, but there is an expectation of improvement after the spring maintenance. Styrene is expected to oscillate between 6300 - 6700 yuan/ton due to sufficient supply and weak cost support [13]. - **LPG**: The LPG market shows a pattern of stable prices, inventory reduction, and some improvement in downstream demand. The price is expected to be relatively stable with some fluctuations [15]. - **Polyester Industry Chain**: For PX, it may continue to be strong unless there is substantial production reduction in the polyester sector. PTA is expected to follow the raw material price with limited independent movement. MEG is expected to oscillate at a low level. Short - fiber prices follow the raw material, and the processing fee of bottle - chips is expected to be compressed [17]. - **Crude Oil**: The market is dominated by geopolitical factors. With high supply and weak demand, the price is expected to oscillate, and attention should be paid to the price of Brent crude at $60 per barrel [18]. - **Urea**: The futures price is weak, while the spot price is rising. The Indian tender is beneficial for exports, but high supply and weak demand in the domestic market lead to a difficult price trend. The futures price is expected to oscillate between 1680 - 1730 yuan/ton [20]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - Overseas, US CPI and core CPI in November dropped to 2.7% and 2.6% year - on - year, far lower than market expectations, but data credibility is questionable. The market reacted positively, with expectations of Fed rate cuts. The ECB maintained rates and was vague on easing [2]. - Domestically, the A - share market showed a structured rise with reduced trading volume, and the bond market was also divided. The short - term A - share market is expected to be volatile and weak, and the bond market's main trend is unclear [3]. - For precious metals, gold and silver prices may face adjustment risks, and platinum and palladium should not be chased at high prices due to regulatory measures and data uncertainties [4][5]. - Copper prices are expected to remain high and volatile in the short term due to mild inflation data and tight fundamentals [6][7]. - Aluminum prices are expected to rise steadily due to positive macro factors and good fundamentals [8]. - Alumina prices are expected to be weak and volatile as the supply remains abundant [10]. - Cast aluminum prices are expected to oscillate at a high level due to cost support [11]. - Zinc prices are expected to continue oscillating as there is support from inventory reduction but also pressure from market uncertainties [12]. - Lead prices are expected to maintain a narrow - range oscillation due to low inventory and cost support [14]. - Tin prices' upward momentum is weakening, and chasing high prices should be cautious [15]. - Industrial silicon prices are expected to be strong and volatile as supply and demand show marginal improvement [17]. - Steel prices are expected to follow a short - term rebound but maintain an oscillating pattern [19]. - Iron ore prices are expected to oscillate as the supply - strong and demand - weak pattern remains [20]. - Coking coal and coke prices are expected to rebound in the short term due to policy stimulation [21]. - Soybean meal and rapeseed meal prices are expected to oscillate as US soybeans continue to decline and the supply in China is sufficient [22][23]. - Palm oil prices are expected to be weak and oscillating as Indonesia's palm oil inventory decreased in October and market factors are complex [24]. 3. Summaries According to Relevant Catalogs 3.1 Macro - Overseas: US November CPI and core CPI were 2.7% and 2.6% year - on - year, lower than expected. The data's credibility is in doubt. The market expects Fed rate cuts. The ECB maintained rates and didn't give clear easing guidance [2]. - Domestic: A - shares rose with reduced volume, showing a structured market. The bond market was divided. The short - term A - share market is expected to be volatile and weak, and the bond market's main trend is unclear [3]. 3.2 Precious Metals - Gold and silver prices had a short - term rise and then a fall after the US CPI data release, facing increased adjustment risks. Platinum and palladium prices continued to rise, but the Guangzhou Futures Exchange restricted platinum futures' daily opening positions, so chasing high prices is not recommended [4][5]. 3.3 Copper - On Thursday, SHFE copper's main contract oscillated upward, and LME copper oscillated around $11,700. Mild inflation data is beneficial for a dovish stance. Fundamentally, mine restarts are slow, and inventories are low. Copper prices are expected to remain high and volatile [6][7]. 3.4 Aluminum - On Thursday, SHFE aluminum's main contract closed at 21,955 yuan/ton, up 0.25%. LME aluminum closed at $2,917/ton, up 0.38%. US inflation data boosted rate - cut expectations, and the reduction of aluminum ingot inventory verified year - end consumption resilience. Aluminum prices are expected to rise steadily [8]. 3.5 Alumina - On Thursday, alumina futures' main contract closed at 2,553 yuan/ton, up 0.12%. The supply is abundant with inventory flowing into the market and imports arriving. Alumina prices are expected to be weak and volatile [9][10]. 3.6 Cast Aluminum - On Thursday, cast aluminum alloy futures' main contract closed at 21,110 yuan/ton, up 0.45%. At the end of the year, both supply and demand decreased. Cast aluminum prices are supported by the cost of scrap aluminum and are expected to oscillate at a high level [11]. 3.7 Zinc - On Thursday, SHFE zinc's main contract oscillated narrowly. The US CPI data had a limited impact. Consumption showed resilience, and social inventory declined. However, LME had continuous small - volume warehousing. Zinc prices are expected to continue oscillating [12]. 3.8 Lead - On Thursday, SHFE lead's main contract oscillated narrowly. The supply side had a mixed situation of reduction and resumption. The terminal was in the off - season, but low inventory and cost support are expected to keep lead prices oscillating narrowly [13][14]. 3.9 Tin - On Thursday, SHFE tin's main contract oscillated strongly at night. The supply - side disturbance support weakened, and downstream acceptance of high - priced tin was under pressure. Tin prices' upward momentum is expected to weaken [15]. 3.10 Industrial Silicon - On Thursday, industrial silicon oscillated strongly. The supply side is generally stable, and the demand side shows some changes. Social inventory rose slightly. Industrial silicon prices are expected to be strong and volatile [16][17]. 3.11 Steel (Screw and Coil) - On Thursday, steel futures oscillated and rebounded. The output and apparent demand of the five major steel products were slightly adjusted, and inventory continued to decline. Steel prices are expected to follow a short - term rebound but maintain an oscillating pattern [18][19]. 3.12 Iron Ore - On Thursday, iron ore futures oscillated upward. The supply was strong with high overseas shipments and port inventory accumulation, while the demand was weak as steel mills cut production. Iron ore prices are expected to oscillate [20]. 3.13 Coking Coal and Coke - On Thursday, coking coal and coke futures rose significantly. Policy stimulation strengthened the bottom support. Coking enterprises' costs increased, and the supply was generally loose. Coking coal and coke prices are expected to rebound in the short term [21]. 3.14 Soybean and Rapeseed Meal - On Thursday, soybean meal and rapeseed meal futures showed different trends. US soybeans continued to decline, and the supply in China was sufficient. Soybean and rapeseed meal prices are expected to oscillate [22][23]. 3.15 Palm Oil - On Thursday, palm oil futures showed a mixed performance. Indonesia's palm oil inventory decreased in October due to increased domestic consumption. Palm oil prices are expected to be weak and oscillating [24].
