1. Report's Industry Investment Rating - Steel: Adopt a unilateral range trading strategy; consider participating in cash-and-carry arbitrage for hot-rolled coils and use options strategies to assist spot procurement and sales [5]. - Ferrosilicon and Manganese Silicon: Investment clients should short on rallies, and industrial clients can use accumulating options to protect their spot exposure [5]. - Coking Coal and Coke: Speculators should focus on buying far-month contracts at low prices [5]. - Iron Ore: Hold short positions [5]. 2. Core Viewpoints of the Report - The steel market is expected to run slightly stronger, with prices fluctuating in a narrow range. There may be some room for a decline in iron ore production in December, and attention should be paid to the subsequent winter storage replenishment drive [3]. - The prices of ferrosilicon and manganese silicon are expected to be under pressure and weaken due to the over - supply situation, despite the strengthening cost support [5]. - The first round of coke price cuts has been fully implemented, but the coking coal and coke futures have shown signs of stabilizing and rebounding. It is recommended to buy far - month contracts at low prices, considering the possible downstream replenishment in mid - to - late December [5]. - Iron ore is facing significant pressure at the upper end of the range. Due to the expected increase in inventory and the decline in steel mill profitability, it is advisable to short on rallies [5]. 3. Summary by Related Catalogs Steel - On Monday, both futures and spot prices rose, and trading volume increased. In December, focus on macro - trading expectations, such as the US interest rate cut expectations and China's Central Economic Work Conference [3]. - In the industrial sector, the seasonal off - season has not yet formed a consistent negative narrative. The inventory and production pressure of hot - rolled coils are prominent, which restricts the upside of prices and market participants' willingness to hold inventory. However, funds are not actively shorting steel prices due to low steel mill profitability [3]. - After December, there may be some appropriate inventory replenishment in the industrial sector, providing support at low prices. The iron ore production may decline in December, and then attention should be paid to the start of the winter storage replenishment drive [3]. Ferrosilicon and Manganese Silicon - The prices of ferrosilicon and manganese silicon have rebounded with the black - metal sector, but the driving force is still insufficient [4]. - The steel price is under pressure, steel mill profits are shrinking, iron ore production is decreasing, and direct demand is expected to weaken. With the arrival of the off - season for terminal demand, the negative feedback pressure is gradually accumulating [5]. - Alloy factories have poor profits, but production remains high, and there is insufficient motivation for self - reduction or production control. The medium - term over - supply pressure remains high, and inventory and warehouse receipts are accumulating [5]. Coking Coal and Coke - In the spot market, the first round of coke price cuts has been implemented, the coking coal auction failure rate is high, and most transaction prices have fallen. Affected by the futures rebound, some Mongolian coal traders' quotes are temporarily stable, but market trading is average [5]. - In the futures market, on the first trading day of December, market risk appetite is good. With many domestic meetings in December, market expectations are high. Although the first - round coke price cuts have been implemented, the previous low points in the futures market have priced in 3 - 4 rounds of price cuts. With the increase in risk appetite, coking coal and coke futures have shown signs of stabilizing and rebounding [5]. - The steel data is still good, the apparent demand is seasonally weak but still resilient, production has increased, and the de - stocking slope is similar to the same period. The industrial contradictions are not prominent. Coking coal prices are weak due to the slowdown in downstream replenishment, but there are still fluctuations on the supply side [5]. Iron Ore - Iron ore has reached the upper end of the range - bound trading. In the short term, the arrival volume has increased, and the subsequent shipment volume is expected to remain stable, with no significant unexpected fluctuations [5]. - In the medium term, inventory will continue to accumulate under pressure. Some steel mills in southern China are facing increased losses and weakening demand, leading to maintenance. The steel mill iron ore production has slightly decreased to 268 million tons (-1.6). Steel mill profitability is affecting production willingness, and it is expected that subsequent fluctuations will mainly come from steel mill production cuts, which will lead to a continuous increase in port inventory [5]. - Due to inventory pressure, it is difficult for iron ore to break through the upper end of the range, and the recommended strategy is to short on rallies [5].

Look for range - trading opportunities [49]. 2.11 Non - ferrous Metals (Copper) - Minmetals Resources' Izok Corridor project exploration made progress, and a copper smelter in Kamoa - Kakula was ignited. The macro - level support may weaken, but the domestic inventory reduction boosts bullish sentiment [50][51][52]. - Investment advice: The copper price is expected to continue to rise in an oscillating manner. Recommend buying on dips. Pay attention to the widening of the C - L spread [52]. 2.12 Non - ferrous Metals (Lithium Carbonate) - A 60,000 - ton power - battery recycling project in Yichang was launched. The production of lithium carbonate decreased last week, and the demand in the off - season may weaken.

Report Industry Investment Rating No specific industry investment rating is provided in the report. Core Viewpoints The report presents a comprehensive analysis of various commodities and markets, with most commodities expected to show an oscillatory trend, and some showing a tendency of oscillating strongly or weakly. Market conditions are influenced by multiple factors such as supply - demand relationships, policy environments, and geopolitical events [3]. Summary by Category Financial - **Stock Index**: In a market with shrinking volume, potential lifting of the ban on share sales and reduction pressure, and a policy window period, funds are congested and waiting to be released. A dumbbell - shaped strategy of looking at the long - term and trading in the short - term is recommended, with an oscillatory trend [3]. - **Treasury Bonds**: The central bank conducts treasury bond trading, and subsequent aggregate monetary policy tools may be further implemented. In the fourth quarter, the allocation demand of institutional investors may increase seasonally, and the market is expected to oscillate strongly. Currently, opportunities for curve steepening and positive spreads are recommended [3]. Precious Metals - **Gold and Silver**: Attention should be paid to the release of US PMI and ADP employment data this week. The price of London gold is expected to be in the range of [4000, 4400], and that of London silver in the range of [53, 60], showing an oscillatory trend [3]. Base Metals - **Copper**: Supply constraints persist, and supply - disturbing factors are increasing, so the copper price is expected to oscillate strongly [3]. - **Aluminum**: In the short - term, the macro - sentiment is volatile, and the fundamentals are stable, so the aluminum price is expected to oscillate strongly. In the medium - term, the marginal increase in supply is limited, and demand has certain resilience, so the price center is expected to rise [3]. - **Alumina**: The current supply - demand is in excess, but the valuation is in a low - level range, so it is expected to oscillate [3]. - **Zinc**: Recently, the inventory of LME zinc has increased significantly, but the "short squeeze" has not eased significantly. Entering the off - season of consumption, downstream demand for zinc ingots is weakening, and supply remains high. However, the export window for domestic zinc ingots has opened, and domestic inventory is decreasing. The zinc price is expected to oscillate [3]. - **Tin**: With the current tightness in the ore end, the bottom support for the tin price is strong, so it is expected to oscillate strongly [3]. - **Lead**: Currently at the end of the traditional peak consumption season, but the replacement of old cars and electric bicycles is still ongoing. The orders for lead - acid batteries have improved, and the procurement demand for lead - zinc is expected to remain high. Recently, many primary and secondary lead smelters have carried out maintenance, and lead ingot production has declined. The lead price is expected to oscillate [3]. - **Nickel**: The current supply - demand is loose, and the nickel price is expected to oscillate weakly in the short - term. In the long - term, it depends on the official announcement of next year's nickel ore quota in Indonesia, which may decrease, so there is uncertainty in supply, and the nickel price is expected to oscillate [3]. - **Stainless Steel**: Due to the suppression of the price by the fundamentals during the seasonal off - season transition, but considering the long - term suppression of industry profits and the support from the ore end, the price is expected to oscillate, and attention should be paid to inventory changes and cost changes [3]. New Energy Metals - **Lithium Carbonate**: The short - term supply - demand is in a tight balance, with medium - term looseness and short - term shortages coexisting. The price is expected to oscillate widely [3]. - **Polysilicon**: The anti - involution policy has significantly boosted the polysilicon price, but the demand is also weakening. The price is expected to oscillate widely. Attention should be paid to whether there are substantial policy signals at the end of the year and the process of new warrant registration [3]. - **Industrial Silicon**: If the silicone industry cuts production, the demand for industrial silicon will further weaken, and the inventory pressure may increase again. However, the short - term market sentiment is volatile. The price is expected to oscillate, and attention should be paid to the progress of new warrant registration [3]. - **Cobalt**: The conflict in eastern Congo has escalated, and although it has not affected cobalt mining for the time being, the potential risks are expected to increase, so the cobalt price is expected to oscillate strongly [3]. Black Building Materials - **Coking Coal**: Although the fundamentals of coking coal have slightly deteriorated, the current valuation of the futures market is too low, and the low - production state in China will continue. The downstream has strong expectations of replenishing inventory, and the spot price has bottom support. The near - month contract price is expected to oscillate, and the far - month contract is expected to oscillate strongly [3]. - **Coke**: The fundamentals of coke are still healthy, and the price mainly follows the cost of coking coal. In the case of the continued weakening of raw material spot prices, the current round of price cuts is expected to be implemented, but there are still expectations of winter inventory replenishment. The continuous implementation of multiple rounds of price cuts is less likely, and the futures price is expected to oscillate following coking coal [3]. - **Iron Ore**: There is still a seasonal decline expectation for molten iron output, the rigid demand support is gradually weakening, and the inventory replenishment demand has not been significantly released. After the previous price increase, there is insufficient support for further upward movement. The short - term ore price is expected to oscillate [3]. - **Hot - Rolled Coil**: The demand side still has resilience, and inventory continues to decline, but the pressure of high - year - on - year inventory remains, and the fundamental contradiction has not been resolved. The Sino - US presidential call sent a positive signal, and the Central Economic Work Conference in December is approaching, and the macro - environment is still warm. The futures price has the driving force to rebound from a low level, but the upward space is limited, and it is expected to oscillate widely at a low level [3]. - **Rebar**: The fundamentals of rebar have continued to improve recently. The National Development and Reform Commission organized a symposium on the cost determination of disorderly price competition. The Central Economic Work Conference in December is approaching, there are still expectations of overseas interest rate cuts, and the Sino - US presidential call sent a positive signal, and the macro - environment is warm. The futures price has the driving force to rebound from a low level. However, the inventory level of rebar is still high year - on - year, and as the off - season deepens, the demand expectation is still under pressure, and the fundamental highlights are limited. The upward space of the futures price is limited, and it is expected to oscillate widely at a low level [3]. - **Silicon Ferrosilicon**: The firm cost supports the bottom of the silicon ferrosilicon price, but the market supply - demand is still loose, and the price increase is weak. The cost transfer to the downstream is difficult. The main - contract futures price is expected to operate at a low level. Attention should be paid to the adjustment of raw material prices and settlement electricity prices [3]. - **Manganese Silicate**: The cost of manganese silicate still has support, but the market supply - demand is loose, and the upward pressure on the price is large. The cost transfer to the downstream is difficult. The futures price is expected to operate at a low level. Attention should be paid to the adjustment range of raw material prices [3]. - **Glass**: In the short - term, the improvement in demand is obvious, and the fundamentals have improved, but the improvement is limited. Only when subsequent cold - repair is further implemented can the glass price continue to recover. Otherwise, the price may decline under the pressure of inventory accumulation during the Spring Festival. In the long - term, due to the increasingly strict environmental protection requirements, the supply side will face clearance and cost increase, and the far - month valuation may rebound [3]. - **Soda Ash**: In the short - term, the supply - demand fundamentals of soda ash have improved to some extent. If the production remains low after the mid - stream inventory reduction, there may be a short - term positive feedback, and the price is expected to oscillate. In the long - term, there will still be low - cost production capacity coming on - stream, and the supply - demand surplus will intensify. The price needs to continue to decline to suppress production [3]. Energy - **Crude Oil**: It is oscillating and waiting for the guidance of the OPEC+ meeting and geopolitical factors [3]. - **Natural Gas**: The European natural gas price is oscillating, and the US natural gas price may be strong in the short - term [3]. - **Steam Coal**: Attention should be paid to the impact of supply - side policies and the change in inventory replenishment rhythm. The medium - and long - term reasonable price range of 570 - 770 still has great reference value [3]. - **Fuel Oil**: High - sulfur fuel oil and low - sulfur fuel oil are both expected to oscillate and decline [3]. - **Asphalt**: The futures price is expected to oscillate and decline [3]. - **LPG**: Attention should be paid to whether the optimistic expectations for Saudi Arabia on December 8 can be fulfilled. Currently, the basis is continuously low, the pressure on refining margins is increasing, and the upward space of the spot price is expected to be relatively limited. The upward space of the futures price should not be overly optimistic. Attention should be paid to the generation of warrants [3]. Chemicals - **Benzene Ethylene**: The inventory accumulation pressure of pure benzene in December is still being realized, and it is expected to oscillate in the short - term [3]. - **PX**: In the short - term, it is greatly affected by sentiment and cost. The price is expected to operate in the range of [6650, 6950], and the PXN is expected to oscillate in the range of [250, 290] US dollars per ton [3]. - **PTA**: It is greatly affected by cost and market sentiment. In the short - term, it will oscillate following the cost, and the price will be sorted in the range of [4650, 4850]. The processing margin of the 01 contract can be operated in the range of [220, 300] yuan per ton [3]. - **Ethylene Glycol**: The price is expected to continue to oscillate in the low - level range in the short - term, and the upward elasticity of the price is obviously pressured. The EG01 - 05 spread can be cautiously reverse - arbitraged at high levels, and the operation space is [-75, -100] [3]. - **Short - Fiber**: The absolute price of short - fiber fluctuates with the raw material, and the processing margin will fluctuate between 950 - 1100 yuan per ton. A short - PF and long - TA position can be lightly established [3]. - **Bottle Chip**: The processing margin has strong support at the short - term range bottom, but the upward pressure is also large. It is expected to operate in the range of [400, 550], and the absolute price of bottle chips will fluctuate with the raw material [3]. - **Methanol**: After the overseas fluctuation information is confirmed, the futures price quickly rebounded to fulfill the expectation. After the rebound this week, the upward momentum of the methanol futures price has weakened. Attention should be paid to whether the digestion trend of coastal inventory can continue, and it is expected to oscillate [3]. - **PP and PE**: The upward space is limited, and they should be regarded as range - bound. The change in maintenance is still the key point of observation [3]. - **Caustic Soda**: The electricity price in December has decreased, and the cost of caustic soda has decreased by 80 yuan per ton, opening the downward space of the futures price. If the low - profit situation promotes upstream production cuts or the warrant logic before delivery intensifies, the futures price may stabilize [3]. - **PVC**: The 01 contract is facing position - taking games in the short - term and shows a small - scale rebound. In the long - term, if there are no positive factors such as upstream production cuts due to low profits, increased exports, or unexpected policies, the futures price may return to a weak trend [3]. - **Urea**: The domestic urea fundamentals show a pattern of strong supply and weak demand, which is difficult to change. After the inspection of the December reserve progress, the short - term reserve push may return to the normal progress, and this demand support is relatively stable in the long - term. It is expected to oscillate in the short - term, and attention should be paid to the overall progress of off - season storage [3]. Agriculture Feed and Livestock - **Soybean and Soybean Meal**: The US soybean price is expected to oscillate strongly at a high level. The import crushing margin has been repaired, and soybean procurement has accelerated. The oil mill's soybean meal inventory is slowly decreasing seasonally, and downstream customers are placing orders at low - level futures prices, with increased spot trading volume and a rising basis. The soybean - rapeseed meal spread is expected to oscillate strongly. Attention should be paid to the long - position opportunity of the M2605 contract after the contract roll [3]. - **Corn**: In the short - term, it is expected to oscillate strongly. Before the effective repair of downstream and mid - stream inventories, the price is likely to oscillate at a high level. It is necessary to wait for the release of upstream inventory and the alleviation of downstream supply tension [3]. - **Pig**: In the near - term, the pig price will continue to be weak, as the fourth - quarter pig production is still in the period of high - capacity realization, and the end - of - year pressure to sell large pigs is increasing. In the far - term, the Ministry of Agriculture is guiding enterprises to cut production, and the continuous loss of breeding profits is conducive to the reduction of production capacity in the fourth quarter. The far - month contract price is supported by the expectation of production capacity reduction. The pig industry shows a pattern of "weak reality + strong expectation", and attention should be paid to the reverse - arbitrage strategy opportunity [3]. Soft Commodities - **Apple**: Against the background of strong support for the spot price, combined with the expectations of Tomb - Sweeping Festival stocking and possible weather speculation, the futures price is relatively firm, and the sentiment is optimistic. Attention can be paid to the low - long opportunity after a pull - back, and subsequent attention should be paid to the weather changes in the producing areas. The price is expected to oscillate strongly for the time being [3]. - **Rubber**: It is not the time for a trending market, and the current price is closer to the upper pressure level. In terms of arbitrage, the RU - MR spread reached a phased high last week, and one can choose to exit and wait and see [3]. - **Cotton**: In the short - term, it is expected to oscillate in a range; in the long - term, the valuation is low, and it is expected to oscillate strongly. It is advisable to go long at a low price [3]. - **Paper Pulp**: The futures market is mainly about the game of warrants, and the paper pulp futures price is expected to oscillate widely [3]. - **Sugar**: In the medium - and long - term, it is expected to oscillate weakly. Since the global sugar market is expected to have a supply surplus in the new crushing season, the sugar price has a downward driving force. The operation strategy is to go short on rallies [3]. Shipping - **Container Shipping on European Routes**: It is expected to oscillate [3].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - In the future one - month overall operation strategy, it is recommended to be cautious, observe, or defend. For iron ore, in the short - term, hold a cautious and wait - and - see attitude before the basis convergence is basically completed, and in the medium - term, hold a bearish operation idea for far - month contracts such as the 05 contract. For coking coal and coke, adopt a defensive strategy, and in the medium - term, pay attention to demand recovery and the degree of inventory reduction, and be vigilant against supply - demand mismatch disturbances. For steel, sell out - of - the - money call options, and hold a bearish operation idea for far - month futures [1][2][33]. Summary According to the Directory I. Iron Ore: Import Surge and Increasing Inventory Pressure - **Supply**: High ore prices have stimulated production increases. Overseas mines have repaired their profits since August, and the overseas shipping volume in November continued to be high. The commissioning of new mines such as Simandou in Guinea and Mbalam - Nabeba in West Africa will increase the medium - and long - term supply pressure on the global iron ore market. The latest data shows that the overseas ore supply has continued to increase year - on - year since November. The four - week shipping volume of major global ports was 131.422 million tons, a year - on - year increase of 7.68%, and the four - week arrival volume at 45 ports was 106.443 million tons, a year - on - year increase of 9.77% [4][7]. - **Demand**: As of the end of November, the profit - making ratio of domestic sample blast - furnace steel mills has dropped to 35.06%, significantly lower than the beginning - of - year level, and the theoretical profit per ton of steel is in an overall loss. Steel mills' production willingness has decreased, and iron ore demand has decreased. In December, due to the low profit per ton of steel and the expanding loss of downstream steel mills, iron ore demand is likely to continue to be weak [11]. - **Inventory and Price**: Since the beginning of August, the inventory of imported iron ore at 45 ports has bottomed out and rebounded, and accelerated to rise to 153 million tons in November. In the long - term, the global iron ore market faces the commissioning pressure of new projects. The Simandou iron ore was commissioned and shipped on November 11th, and is expected to arrive at the port by the end of January at the latest, with an expected monthly import increase of about 1.5 - 2 million tons. The off - season of terminal steel demand and the unclear prospects, as well as the losses of steel mills, will put pressure on ore prices [14]. II. Coking Coal and Coke: Weak Reality Pressure is Emerging, but Be Vigilant Against Repeated Policy - Based Production Restrictions - **Supply**: The domestic production of raw coal by sample mines has remained stable overall. Although the National Development and Reform Commission has emphasized energy supply guarantee during the heating season, there is still a risk of repeated policy - based production restrictions in December, which may lead to a phased mismatch between supply and demand. In terms of imports, the overall imports were at a high level in November due to high domestic prices [16]. - **Demand**: The overall coal demand has entered the off - season. The consumption of coking coal and coke by steel mills has been stable in the short - term, but the subsequent growth space is limited. The winter storage and replenishment rhythm of thermal power plants has slowed down. The winter coal demand is generally lower than that in summer, and the higher - than - normal temperature in the northern region this year has led to poor demand expectations [19]. - **Inventory and Price**: In November, the raw coal inventory and inventory days were still at the highest level in the same period in the past five years, with slow inventory turnover and large inventory pressure, which still suppresses the prices of coal and downstream coking coal and coke. It is recommended to adopt a defensive strategy. In the medium - term, pay attention to demand recovery and the degree of inventory reduction, and be vigilant against supply - demand mismatch disturbances [22]. III. Steel: Disappointing Peak - Season Consumption and Soaring Inventory Pressure - **Production**: Steel mills' profits are low, and production enthusiasm has been frustrated. In November, the profit per ton of steel continued to be under pressure, and the profit - making ratio of blast - furnace steel mills (accounting for 90% of steel supply) dropped to 35.06% at the end of the month, lower than the beginning - of - year level. From January to September, the cumulative output of crude steel decreased by 2.9% year - on - year, and the output in October continued to decline on the basis of September [26]. - **Demand**: In November, the overall steel consumption was at a low level in the same period in the past five years, mainly dragged down by building materials. Due to insufficient project funds and winter cooling, the construction progress has slowed down, and the consumption of building steel is weak. Although the consumption of steel plates is at a high level in the same period in the past five years, the increase in demand for steel plates is not enough to make up for the decrease in demand for building materials [29]. - **Inventory and Price**: Since October, the crude steel inventory has accelerated to rise to the highest level in the same period in the past five years. The inventory of rebar and hot - rolled coils has increased significantly compared with last year, which increases the potential selling pressure in the steel market, leading to insufficient upward driving force for steel prices and the existence of downward risks [31]. IV. Outlook for the Future: Adopt a Defensive Strategy and Pay Attention to Supply Disturbances - Overall, in December, the supply pressure of furnace materials is likely to continue to increase, and the inventory pressure of terminal steel is gradually emerging. It is recommended to be cautious, observe, or defend in the overall operation strategy in the next month. Pay attention to key variables such as the incremental import of iron ore, changes in port inventory, coal mine production restriction intensity, changes in mine inventory, steel mill production reduction intensity, and the implementation of fiscal policies [33][35].

Report Industry Investment Ratings No relevant content provided. Core Views of the Report - The market shows mixed trends across various commodities, with geopolitical factors, supply - demand dynamics, and policy expectations influencing prices. Each commodity has its own unique supply - demand situation and price - influencing factors, and the overall market lacks a unified trend [2][4][21] - For financial products such as stocks and bonds, geopolitical and macro - economic factors also play important roles, and short - term caution is recommended [48][49] Summary by Commodity Categories Energy - **Crude Oil**: Night - time international oil prices rose slightly. Market expectations for a cease - fire in the Russia - Ukraine conflict are still wavering. OPEC may maintain its production policy, and the increasing expectation of a December Fed rate cut boosts oil prices [2] - **Fuel Oil & Low - sulfur Fuel Oil**: The fuel oil market showed a differentiated performance overnight. High - sulfur fuel oil rose slightly with the cost of crude oil, while low - sulfur fuel oil was weak. In the future, the overall contradiction is limited, with high - sulfur fuel oil affected by geopolitical risks and low - sulfur fuel oil having sufficient supply [22] - **Asphalt**: The commercial inventory of asphalt is decreasing faster. The December production plan is lower year - on - year and month - on - month. The demand will decline seasonally, and the market is expected to be loose at the end of the year, putting pressure on prices [23] Metals - **Precious Metals**: Overnight, precious metals showed a volatile performance. The uncertainty of interest rate cuts and geopolitical prospects led to high - level oscillations. On the first day of the listing of platinum futures, the price fluctuated sharply, and attention should be paid to the strategy of shorting volatility [3] - **Base Metals**: - **Copper**: The average copper price this year was strong. Next year, the growth rate gap between supply and demand may narrow, and the price increase will be supported by factors such as liquidity and demand for green carbon and intelligent computing. Short - term, a small amount of chasing up can be attempted [4] - **Aluminum**: Overnight, Shanghai aluminum continued to oscillate. The inventory decreased, and the demand has resilience but lacks highlights. The industry has limited contradictions, and the price will mainly oscillate [5] - **Zinc**: Overseas funds have a strong influence. The domestic ore supply is tightening, and the bottom support is strong, but the consumption outlook is under pressure. The short - term price will oscillate in the range of 22,200 - 23,000 yuan/ton [8] - **Lead**: The LME lead inventory is at a high level, and the decline of the external market has slowed down. The domestic supply and demand are relatively balanced, and the price will oscillate in the range of 16,800 - 17,500 yuan/ton [9] - **Nickel & Stainless Steel**: Shanghai nickel oscillated, and the market sentiment was cold. The cost support of stainless steel continued to decline, and the price is recommended to be shorted on rebounds [10] - **Tin**: Overnight, LME tin turned down. Shanghai tin broke through 300,000 yuan and then adjusted. Pay attention to the inventory changes this week. It is recommended to short on rallies and hedge risks with call options [11] - **Ferroalloys**: - **Silicon Manganese**: The market has an increasing expectation of coal mine supply guarantee. The production is at a relatively high level, the inventory is slowly increasing, and the bottom support is expected to move down [19] - **Silicon Iron**: The market has an increasing expectation of coal mine supply guarantee. The demand has resilience, the supply is at a high level, and the bottom support will be tested [20] Chemicals - **Urea**: The urea futures price continued to rise, and the spot market rose slightly. The supply is sufficient, and the demand has increased in the short term, but the supply - demand surplus pattern is expected to continue [24] - **Methanol**: There is a game between strong expectations and weak reality. The short - term can consider unilateral long or positive spread trading, but the high inventory in ports may suppress the price increase [25] - **Pure Benzene**: The US gasoline crack spread has weakened. The domestic device load has been slightly adjusted down, and the price will oscillate [26] - **Benzene Ethylene**: The supply - demand structure has been slightly improved, the profit has been repaired, and the price will continue to oscillate [27] - **Polypropylene, Plastic & Propylene**: The supply of propylene in Shandong is slightly tight, and the price has risen, but the cost pressure on downstream products may limit the increase. The supply of polyethylene is stable, and the demand is weakening [28] - **PVC & Caustic Soda**: PVC is oscillating. The export situation may improve, and the price may stop falling and stabilize. Caustic soda is also oscillating, with high inventory and weak demand [29] - **PX & PTA**: The short - term supply - demand of PX is weakening, but the medium - term is expected to be strong. PTA is driven by cost, and the processing margin is expected to be repaired [30] - **Ethylene Glycol**: The weekly output has decreased, and the supply has improved marginally, but the medium - term is still weak [31] - **Short - fiber & Bottle - grade Chip**: Short - fiber has no new investment pressure, and the price fluctuates with raw materials. Bottle - grade chip demand is weakening, and the cost is the main driving factor [32] Agricultural Products - **Grains & Oilseeds**: - **Soybeans & Soybean Meal**: The domestic soybean supply is sufficient, the soybean meal inventory is at a high level, and the supply is loose. Pay attention to the signing and implementation of the Sino - US economic and trade agreement and South American weather [36] - **Soybean Oil & Palm Oil**: The overseas supply - demand of palm oil is weak, but the marginal negative factors have eased. Soybean oil is affected by the price of US soybeans, and attention should be paid to US soybean exports and South American weather [37] - **Rapeseed Meal & Rapeseed Oil**: The focus of the rapeseed market is on the customs clearance and crushing of Australian rapeseeds. The external market has a short - term boost to rapeseed meal, and a wait - and - see strategy is recommended [38] - **Corn**: The north port corn price is firm, and the supply and transportation of northeast corn are a concern. The downstream inventory is low, and the replenishment intention has increased. Wait for the signing of the Sino - US trade agreement and pay attention to the sales progress of new corn in the northeast [40] - **Livestock & Poultry Products**: - **Hogs**: The number of fertile sows has decreased, and the industry is reducing production capacity. The short - term price is weak, and the long - term may form a double - bottom pattern [41] - **Eggs**: The market is trading on the expectation of a decline in future inventory. The long - term supply pressure is expected to ease, and the fundamentals are expected to improve [42] - **Cash Crops**: - **Cotton**: US cotton has rebounded. The domestic cotton cost provides support, and the sales progress is fast. The cotton yarn market is weak, and a wait - and - see strategy is recommended [43] - **Sugar**: The international sugar supply is sufficient. The expected sugar production in Guangxi in the 25/26 season is relatively good, and attention should be paid to the production situation [44] - **Apples**: The futures price is oscillating at a high level. The short - term price is strong, but the long - term may face inventory pressure. Pay attention to the de - stocking situation [45] - **Wood**: The futures price is oscillating. The low inventory provides support, and a wait - and - see strategy is recommended [46] - **Paper Pulp**: The futures price has continued to fall. The domestic port inventory is at a high level, the supply is loose, and the demand is weak. A wait - and - see strategy is recommended [47] Others - **Shipping**: The container shipping index (European line) shows a differentiated trend. The far - month contract is under pressure from the resumption of navigation expectations, and the near - month contract is dragged down by the weak spot market. Consider the reverse spread strategy for near - month contracts [21] - **Financial Products**: - **Stock Index**: The stock market closed down, and the futures index also fell. Geopolitical and macro - economic factors have an impact. A wait - and - see and defensive strategy is recommended [48] - **Treasury Bonds**: The treasury bond futures closed down, and the market is trading lightly. The price will oscillate weakly in the range, and cautious operation is recommended [49]

Report Overview - The report focuses on the meso - level rotation of commodities, aiming to combine "subjective + quantitative" concepts. It provides a theoretical foundation for subsequent model building [1][63]. Industry Investment Rating - No industry investment rating is provided in the report. Core Views - The report emphasizes the construction of a dynamic cognitive system for investment. It analyzes the rotation phenomena and mechanisms in the equity and commodity futures markets, and constructs a research framework for macro - and fundamental - valuation rotation in the inventory cycle. It also quantifies the meso - level rotation targets as commodity "variety clusters" [1][63][64]. Summary by Directory 1. Significance of Meso - level Research - In the financial market, a dynamic cognitive system is needed for investment. Since 2022, the Chinese commodity futures market has changed, with lower volatility and reduced effectiveness of factors. Research on meso - level "commodity collections" can avoid co - decline risks, capture structural opportunities, and identify potential trends [3]. 2. Meso - level Rotation in the Equity Market 2.1 Rotation Phenomenon in the Equity Market - The size premium and value premium in the Fama - French three - factor model are core factors for explaining stock return differences, providing a theoretical basis for style rotation [4]. 2.2 Formation Mechanism: Cycle Alternation and Capital Game - **Cycle Alternation (Top - down)**: Style rotation in the equity market stems from the cycle of the economic cycle. Different stages of the economic cycle lead to different dominant styles, such as small - cap and growth styles in the early recovery stage, and large - cap and value styles in other stages [10][12]. - **Capital Game (Bottom - up)**: Style rotation is driven by the game between existing and marginal funds. Existing funds lead to style differentiation, marginal funds strengthen the style, and style conversion occurs when the valuation deviates from the fundamentals [15][16]. 3. Meso - level Rotation in the Commodity Futures Market 3.1 Rotation Phenomenon in the Commodity Futures Market - By analyzing the rotation speed, intensity, long - short suitability of the first and last positions, and the distribution of the first and last positions of commodity futures market indices, it is verified that there is a rotation phenomenon in the commodity futures market. The first - place average return is 5.79%, the last - place is - 4.43%, and the average difference is 10.22% [22][26][29]. 3.2 Formation Mechanism: Game between Reality and Expectation in the Inventory Cycle - The meso - level rotation in the commodity futures market is driven by the transfer of the main contradiction in the inventory cycle. Different stages of the inventory cycle have different logics, such as "reality - driven, expectation - following" in the passive de - stocking stage and "expectation - driven, reality - pressured" in the passive re - stocking stage [30][33][34]. 3.3 Dynamic Framework: Rotation of Macro - financial and Fundamental Valuations - A preliminary research framework for macro - and fundamental - valuation rotation in the inventory cycle is constructed based on Bayesian thinking. The reality side is represented by fundamental valuation, and the expectation side is represented by macro - valuation [40][44]. 4. From Sector to Variety Cluster Rotation - Sector indices have limitations, so variety clusters are introduced. By considering the industrial chain and return clustering, 16 variety clusters are divided, including those in the black, non - ferrous, energy - chemical, agricultural, and precious metal sectors. The variety clusters have lower correlation and better risk - dispersion properties [49][57][60]. 5. Summary - The report combines "subjective + quantitative" concepts. It analyzes the rotation phenomena and mechanisms in the equity and commodity markets, constructs a research framework, and divides variety clusters, providing a theoretical basis for subsequent model building [63][64][65].
