Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. Core Views Crude Oil - Wednesday saw a rebound in crude oil prices due to geopolitical tensions and the Fed's interest - rate cut. However, the supply - demand pattern remains loose. Short - term Brent crude is expected to fluctuate between $60 - 65 per barrel. Keep an eye on the US - Venezuela situation and Russia - Ukraine negotiations [1]. Natural Rubber - Overseas supply increase expectations are rising, and upstream cost support is weakening, but the market may have speculative sentiment. Demand from the tire industry is gradually recovering, but overall capacity utilization improvement is limited. Market inventory is being digested. It is expected that rubber prices will fluctuate between 15,000 - 15,500 [4]. Urea - Urea futures fluctuated and closed higher. Shandong Ruixing's production reduction boosted the spot price in the central region. Downstream demand and export orders reduced the inventory pressure. However, the overall supply - demand outlook is weak, and the price rebound space is limited. Short - term urea is expected to continue to fluctuate between 1630 - 1700 [6]. Methanol - Methanol futures oscillated at a low level. The inland supply increased, but profits were weak. The traditional downstream demand increased slightly, and winter fuel demand provided support. Port imports are expected to decline significantly, and the port de - stocking expectation is strengthened, but the current overseas shipments are still high. Continue to pay attention to MTO05 [7]. Polyolefins - The fundamentals of polyolefins show a pattern of increasing supply and weakening demand, with cost support and inventory pressure coexisting. Polypropylene's supply - side maintenance is high, but there is an expectation of an increase. Polyethylene's supply is increasing, and the upstream inventory is still higher than the same period in previous years [12]. Glass and Soda Ash - Soda ash's supply is high, demand is shrinking, and it is expected to return to the inventory - accumulation pattern. The overall situation is bearish, and short positions can be held. Glass prices were affected by real - estate news, and the current short - term demand has support, but the medium - and long - term outlook is not optimistic [14]. PVC and Caustic Soda - Caustic soda's supply and demand are under pressure, and prices are expected to continue to weaken. PVC's supply pressure remains high, demand is weak, and the overall situation is in an oversupply pattern, with prices expected to continue to be weak at the bottom [15]. Polyester Industry Chain - PX is expected to oscillate between 6600 - 7000 in the short term. PTA is expected to oscillate between 4500 - 4800 in the short term, and TA5 - 9 can be long - short hedged at a low level. Ethylene glycol is expected to oscillate at a low level, and short - term observation is recommended. Short - fiber prices are expected to follow the raw materials and oscillate weakly. Bottle - chip prices follow the cost and the processing fee is expected to be squeezed [16]. LPG No specific view on the trend of LPG is provided in the report, only price, inventory, and开工率 data are presented [19]. Benzene - Styrene - Benzene's short - term supply - demand is weak, and BZ2603 may follow the oil price and styrene fluctuations. Styrene's supply - demand is in a tight balance, but the upside space is limited, and EB01 is expected to oscillate weakly in the short term [21].

1. Report Industry Investment Ratings No industry investment ratings are provided in the reports. 2. Core Views of the Reports Crude Oil - Monday saw a decline in international crude oil prices due to factors such as the resumption of normal operations in some Iraqi oil fields, the continuous production - increase plan of OPEC+, high - level US crude oil production, and an increase in crude oil inventory. However, the ongoing Russia - Ukraine peace talks and the expected Fed rate cut next week are likely to support prices. Short - term Brent crude is expected to trade between $60 - 65 per barrel [1]. Natural Rubber - On the supply side, the continuous decline in Thai raw material prices, the expected increase in overseas supply, the weakening of upstream cost support, and the seasonal increase in overseas shipments have led to a continuous build - up of natural rubber inventory, suppressing spot prices. On the demand side, although tire production is gradually recovering, the overall output increase is limited, and the market is mainly focused on inventory digestion. Short - term rubber prices are expected to be weak and volatile [3]. Methanol - Methanol futures fluctuated narrowly. Spot was purchased on - demand, and the basis was firm. Inland supply increased with plant restarts, but coal - and gas - based production profits were weak. Traditional downstream demand increased slightly, and winter fuel demand provided support. In ports, Iranian gas restrictions led to multiple plant shutdowns, strengthening the expectation of inventory reduction, but high overseas shipments and a large number of registered warrants kept prices weak. Attention should be paid to MTO05 [6][7]. LLDPE and PP - The operating load of polyethylene is gradually increasing, and supply is on the rise. Although upstream inventory is being depleted, it is still higher than the same period last year, and the profit from naphtha cracking is low. The supply of polypropylene is expected to increase after maintenance, and inventory depletion is accelerating, but the overall inventory level is still high. The cost of propylene is strong, compressing the profit of PP production processes. Overall, the fundamentals show a pattern of increasing supply and weak demand, with cost support and inventory pressure coexisting [11]. Pure Benzene and Styrene - For pure benzene, domestic supply is expected to remain stable, downstream cash flow has improved slightly, but demand support is limited. There will be a large number of imports arriving at ports, and port inventory is expected to continue to build up. The short - term price driver is weak, and it may follow oil prices and styrene fluctuations. For styrene, although planned and unplanned maintenance is expected to increase, the overall operating rate may rise slightly, and port inventory may continue to decline. However, due to weak cost support and seasonal weakening of terminal demand, the upside space is limited [14]. Urea - Supply pressure is continuously released as the daily production on December 8 reached a recent high. Demand is in the off - season, and downstream procurement willingness is weak. Although the inventory depletion rate of enterprises has accelerated, the overall inventory level is still high. The mismatch between supply and demand is the main reason for price decline, and short - term prices are expected to be weak and volatile [15]. Polyester Industry Chain - For PX, short - term supply is less affected, but there is an expected supply contraction in the medium - term. Demand is relatively strong, and short - term price drivers are limited, but medium - term support is strong. PTA supply is expected to decrease in November - December, and demand is relatively strong, with short - term price support. Ethylene glycol is expected to continue to decline due to high overseas supply and inventory build - up. Short - fiber supply remains high, and demand is seasonally weak, with limited price drivers. Polyester bottle - chip supply is expected to increase in December, and demand is weak, with processing fees expected to be squeezed [16]. LPG - The data shows price fluctuations in LPG futures and spot markets, as well as changes in inventory and operating rates. Overall, the market is in a state of adjustment, and attention should be paid to changes in supply and demand and international market prices [17]. Glass and Soda Ash - Soda ash production is at a high level, and it is expected to return to the inventory - build - up pattern this week. Downstream demand is shrinking, and the supply - demand pattern is bearish. Glass prices in some regions are weakening, and although there is still some short - term demand support, the medium - and long - term demand outlook is not optimistic [19]. PVC and Caustic Soda - Caustic soda industry supply is abundant, demand is weak, and prices are expected to be weak. PVC supply pressure remains high, demand is low, and although there is some export advantage, overall supply exceeds demand, and prices are expected to be weak [20]. 3.

1. Report Investment Rating No investment rating for the industry is provided in the report. 2. Core Viewpoints LPG Part - Short - term demand is strong, but long - term demand is under pressure. Combustion demand is supported by the arrival of the peak season, and chemical demand remains high despite deep losses in PDH. However, the supply situation in the Middle East is expected to ease, and North American supply may increase, putting downward pressure on the medium - term trend [3][4]. Propylene Part - There is an expectation of increased supply, and the upward driving force is limited. Next week, the supply will increase as restarted devices gradually increase their loads, while demand is weak, and the tight supply - demand situation in Shandong is expected to ease [7]. 3. Summary by Directory LPG Part Price & Spread - Domestic LPG spot prices and basis: Civil gas prices in various regions have changed to varying degrees, with the basis widening. The prices of other LPG types and their basis have also shown different trends [10]. - Regional quotes, discounts, and freight: Asian demand is stable, and the arbitrage space from the US Gulf to the Far East has narrowed [22]. - Propane prices: The prices of AFEI, Propane CP M1, and Propane MB have all fluctuated to some extent [32][33][34]. Supply - US propane shipments have increased month - on - month, and Asian buying interest is high. Canadian propane shipments have also changed. Middle East LPG shipments are in short supply, and shipments are delayed. The total LPG commodity volume is 51.7 million tons (- 0.9%), and the propane commodity volume has decreased by 55,000 tons in terms of import arrivals [40][48][49][70][79]. Demand & Inventory - Chemical demand: PDH operating rate has increased slightly, and MTBE operating rate has remained flat. Domestic LPG refinery inventory is lower than the same period last year, civil gas refinery inventory has decreased, and LPG terminal import cargo inventory has decreased overall [84][86]. Propylene Part Price & Spread - Propylene industrial chain prices: Propane costs are in a consolidation range, propylene prices are relatively strong driven by demand, and PDH profits are relatively stable month - on - month. PP powder and pellet trends are in a narrow range, PO prices are strong, and butanol and octanol profits have improved significantly [117][119]. - Propylene prices: International/US dollar prices have increased slightly, and domestic prices are in a consolidation range driven by demand [121][129]. Balance Sheet - Propylene industrial chain operating rates: The overall upstream operating rate of propylene is 74.1% (- 0.1%). The operating rates of various production methods and downstream products have changed to different degrees [139]. - National propylene balance sheet: The supply and demand situation has changed monthly, and the balance in December shows that the supply - demand pressure in the Shandong market is still high, maintaining a weak outlook [141][158]. - Shandong propylene balance sheet: The supply and demand in Shandong have changed monthly, and the current situation shows that the supply - demand pressure is relatively high [150][153]. Supply - Overall upstream propylene operating rate is 74.1% (- 0.1%). The operating rates of refineries, cracking units, PDH, and MTO have all changed. Some major PDH and MTO devices have restarted or are in the process of restarting, and some are planning to shut down [169][185][191]. - Propylene imports and exports: The import arbitrage space has been repaired [201]. Demand - Downstream propylene: The operating rates of PP, PP powder, PO, acrylonitrile, acrylic acid, n - butanol, octanol, phenol - acetone, and ECH have all changed.

Report Industry Investment Ratings - Bullish: Polysilicon, Lithium Carbonate [1] - Bearish: Fuel Oil [1] - Volatile: Equity Index, Treasury Bonds, Copper, Aluminum Oxide, Zinc, Nickel, Stainless Steel, Tin, Precious Metals, Industrial Silicon, Carbonate, Rebar, Hot Rolled Coil, Iron Ore, Manganese Ore, Silicomanganese, Ferrosilicon, Coke, Coking Coal, Black Metal, Soda Ash, Glass, Jiao Coal, Palm Oil, Cotton, Sugar, Soybean, Pulp, Log, Live Pig, Crude Oil, BR Rubber, PTA, Ethylene Glycol, Short Fiber, Styrene, Urea, Propylene, PVC, Caustic Soda, LPG [1] Core Viewpoints - The market divergence is expected to gradually be digested during the index's volatile adjustment, and the index is expected to rise further with the emergence of new mainlines. The market adjustment provides an opportunity to lay out for the index's further upward movement next year [1]. - Asset shortage and weak economy are beneficial to bond futures, but the central bank has recently warned about interest - rate risks, suppressing the upward space [1]. - For various commodities, their prices are affected by factors such as macro - economic conditions, supply - demand relationships, and cost supports, showing different trends of rise, fall, or volatility [1]. Summary by Category Macro - Financial - Equity Index: Market divergence will be digested during adjustment, with potential for further upward movement. Central Huijin's support limits downside risk. Market adjustment provides a layout opportunity, and traders can build long positions during the adjustment and use the stock - index futures' discount structure to increase the probability of long - term investment success [1]. - Treasury Bonds: Asset shortage and weak economy are favorable, but short - term interest - rate risks are warned by the central bank, suppressing the upward space [1]. Non - Ferrous Metals - Copper: There is a risk of price decline after the digestion of short - term positive sentiment [1]. - Aluminum Oxide: Domestic production and inventory are both increasing, the fundamental situation is weak, and prices are under downward pressure. Attention should be paid to the price changes at the mine end [1]. - Zinc: After the digestion of short - term macro - positive factors and with oversupply, there is a risk of price decline. Pay attention to short - selling opportunities at high prices [1]. - Nickel: Fed's interest - rate cut expectation has risen, and the macro sentiment has improved. Indonesia's restrictions on nickel - related smelting projects have limited impact. Short - term nickel prices may fluctuate with the macro situation. It is recommended to go long at low levels in the short - term range, and the medium - to - long - term supply of nickel will remain in surplus [1]. - Stainless Steel: The macro sentiment has improved, and raw materials have stopped falling. The stainless - steel futures will fluctuate and rebound in the short term. Pay attention to the actual production situation of steel mills [1]. - Tin: After the digestion of macro - positive sentiment, due to the tense situation in Congo and the short - term supply not being restored, tin prices have strengthened. However, beware of the risk of short - term over - rise and fall. The medium - to - long - term outlook is bullish [1]. - Precious Metals: Gold may fluctuate within a range. Silver's short - term price will continue to fluctuate sharply. Platinum is expected to fluctuate in the short term. For palladium, the short - term strategy is to short at high levels, and the medium - term [long platinum, short palladium] arbitrage strategy can continue to be held [1]. - Industrial Silicon: Northwest production is increasing while Southwest production is decreasing. The production schedules of polysilicon and organic silicon in December are decreasing [1]. - Polysilicon: There is an expectation of capacity reduction in the medium - to - long - term. Terminal installations are increasing marginally in the fourth quarter. Large manufacturers are reluctant to sell and are strong in price support [1]. - Lithium Carbonate: The traditional peak season for new energy vehicles is approaching, and the energy - storage demand is strong. The supply side is resuming production and increasing output [1]. Black Metals - Rebar and Hot Rolled Coil: The macro - driving force is increasing in December, providing some rebound momentum. After the futures price rises, it is beneficial for basis positive - arbitrage positions to enter. Do not chase high in single - side trading [1]. - Iron Ore: Direct demand is okay, with cost support, but supply is high, inventory is accumulating, and the price rebound space is limited [1]. - Manganese Ore and Silicomanganese: The short - term production profit is poor, with cost support, but supply is high, and the price rebound is limited [1]. - Ferrosilicon: Supply and demand provide support, and the valuation is low, but short - term sentiment dominates, and price fluctuations are strong [1]. - Soda Ash: Follows glass, but with average supply and demand, there is great resistance to price increase [1]. - Coke and Coking Coal: From a valuation perspective, the decline is close to the end. From a driving perspective, downstream replenishment may start around mid - December. For now, use a short - term strategy for single - side trading and wait and see for the medium - to - long - term [1]. Agricultural Products - Palm Oil: The impact of floods on production is limited, and the near - month inventory pressure is large. The domestic arrival in December is expected to be large, and the basis is expected to be weak [1]. - Cotton: There is support but no driving force in the short term. Future attention should be paid to policies, planting intentions, weather, and demand in the peak season [1]. - Sugar: There is a consensus on short - selling due to global surplus and increased domestic supply. If the price continues to fall, there is strong cost support, but there is a lack of continuous driving force in the short - term fundamentals [1]. - Soybean: China's purchases support the US market. Brazilian weather lacks obvious speculation themes, and the short - term price is expected to fluctuate [1]. - Pulp: There are cancellations of old warehouse receipts and registrations of new ones. The recovery of demand remains to be verified, and the short - term price will fluctuate [1]. - Log: The fundamental situation has weakened but has been priced in the market. The risk - reward ratio of short - selling after a sharp decline is low. It is recommended to wait and see [1]. - Live Pig: The spot price is stabilizing, with demand support, and the production capacity still needs to be further released [1]. Energy and Chemicals - Crude Oil: OPEC + has suspended production increase until the end of 2026, the Russia - Ukraine peace agreement is postponed, and the US has increased sanctions on Russia [1]. - Fuel Oil: Bearish due to factors such as OPEC + policies, the Russia - Ukraine situation, and US sanctions [1]. - Asphalt: Short - term supply - demand contradiction is not prominent, following crude oil. The demand during the 14th Five - Year Plan may be falsified, and supply is sufficient. The profit is high [1]. - BR Rubber: The price support of butadiene is limited. Refinery overhauls may bring a positive expectation. High inventory restricts price increase, but the synthetic valuation is low [1]. - PTA: OPEC's production increase has slowed down, and there are positive factors such as domestic PTA export improvement [1]. - Ethylene Glycol: Inventory is increasing, prices are falling, and cost support is weakening [1]. - Short Fiber: The price follows cost closely, and the basis has strengthened [1]. - Styrene: The cost support is weakening due to factors such as weak Asian benzene prices and reduced US gasoline demand [1]. - Urea: There is limited upward space due to insufficient domestic demand, but there is support from cost and anti - dumping [1]. - Propylene: Supply pressure is large, downstream improvement is less than expected, but cost support is strong [1]. - PVC: Supply pressure is increasing, and demand is weakening [1]. - Caustic Soda: There are factors such as delivery from Guangxi alumina plants, high - load operation, and potential squeezing risks [1]. - LPG: The international oil and gas market returns to a loose fundamental situation. The CP/FEI has rebounded. The price will fluctuate within a range after a decline [1].

1. Report Industry Investment Ratings No investment ratings were provided in the reports. 2. Core Views Polyolefins - The fundamentals of LLDPE and PP show a pattern of increasing supply and weak demand, with both cost support and inventory pressure coexisting [2]. Methanol - The supply of inland methanol increases with the restart of devices, but the profits of coal - and gas - based production are weak. The traditional downstream demand has a slight increase, and the winter fuel demand provides support. In ports, the reduction of imports due to Iranian gas restrictions strengthens the de - stocking expectation and supports prices [6]. Natural Rubber - The supply is expected to increase seasonally, and the inventory continues to accumulate. The terminal demand improvement is weak. The market is expected to fluctuate within the range of 15000 - 15500 [9]. Crude Oil - Geopolitical risks support oil prices in the short term, but the continuous increase in OPEC+ production and the record - high US crude oil production put pressure on the supply - demand pattern.

Report Summary 1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints - Cost - side crude oil is weak, while the fundamentals are marginally improving. The expectation of inventory reduction and supply contraction dominate short - term sentiment. LPG futures may run with a slight upward trend in a volatile manner, and attention should be paid to the rhythm of import arrivals [2][3] 3. Summary of Key Information - **Supply and Inventory**: Supply pressure is marginally relieved. Enterprises actively reduce inventory, and the decrease in imported arrivals has increased the market's expectation of the start of the de - stocking cycle, which supports the sentiment of the futures market [2] - **Cost Factors**: Middle - East propane supply has tightened, and the Far - East arrival premium has stabilized, improving both the cost side and market sentiment. However, OPEC+ continues to increase production, and the expectation of Russia - Ukraine peace talks weakens the geopolitical risk premium, causing the decline of crude oil and dragging down the cost support of LPG [2] - **Demand Situation**: Downstream customers strongly resist high prices, with purchases mainly for essential needs. The incremental demand for winter combustion has not met expectations, suppressing the upward momentum of spot prices [2]
