1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views of the Reports Crude Oil - Recent oil price trends are mainly influenced by geopolitical events in the Middle East and the cold wave in the United States. With geopolitical premiums declining and significant inventory builds in crude oil and refined products, oil prices are under pressure. However, the cold wave in the US has boosted overseas natural gas prices and increased demand for heating oil, supporting oil prices. Currently, crude oil's own driving forces are limited, and short - term oil prices are still dominated by news. Brent crude should be watched for resistance above $66 per barrel, and attention should be paid to changes in geopolitical conflicts in the Middle East [1]. Glass and Soda Ash - **Soda Ash**: The main contract closed at 1,198 yuan/ton on January 23. Spot prices remained basically flat, with a dull market sentiment and mainly downstream rigid demand procurement. On the supply side, the capacity utilization rate slightly decreased, and the comprehensive output slightly declined but remained at a relatively high level. On the demand side, the weekly shipment volume and shipment rate increased month - on - month, with little change in the float glass production line, and the weekly output and industry average capacity utilization rate were flat month - on - month. The photovoltaic glass had no new kiln shutdowns, and the in - production capacity and capacity utilization rate were flat month - on - month. Affected by the expected export - grabbing policy, the photovoltaic glass price remained stable, and the inventory continued to decline. Although the in - plant inventory of soda ash decreased overall and the macro sentiment improved recently, in the context of generally weak fundamentals, the short - term soda ash price is expected to fluctuate weakly, and it is advisable to wait and see [3]. - **Glass**: The main contract closed at 1,064 yuan/ton on January 23. Spot prices showed regional differentiation, with the overall spot price center rising slightly month - on - month. The profits of glass made from different fuels changed little overall, with the profit of petroleum coke - made glass turning negative. The spot market still mainly had rigid - demand transactions. On the supply side, the daily melting volume continued to increase slightly month - on - month, while the start - up rate and industry average capacity utilization rate remained basically flat. On the demand side, the performance of deep - processing orders was differentiated, and the start - up rate of Low - e glass was still at a relatively weak level. Real estate - related data showed that the industry was still in the adjustment stage. The shipment situation of glass enterprises varied, and the inventory also fluctuated. The overall in - plant inventory remained at a high level. As the Spring Festival approached and the consumption off - season arrived, downstream demand gradually decreased, and manufacturers were more willing to actively reduce inventory. It is expected that the rebound space of the futures price is limited, and the short - term trend will remain weakly volatile. It is recommended to pay attention to inventory changes and wait and see [3]. Pure Benzene and Styrene - **Pure Benzene**: The supply - demand situation of pure benzene continued to improve slightly, with a slight decrease in supply and a continued increase in the downstream comprehensive load. The port inventory decreased, but the absolute level of port inventory remained high, and its own driving force was still limited. Recently, styrene was driven by exports, and its port inventory decreased significantly. Coupled with news of unexpected shutdowns of domestic and foreign plants, the styrene trend was strong, driving up the absolute price of pure benzene. Recently, the profit of styrene has expanded significantly, and the price difference between styrene and pure benzene has widened significantly. However, styrene's downstream has cut production due to increased losses, and there are expectations of restarting two maintenance plants next week. It is expected that the room for further expansion of the price difference is limited, and there is an expectation of compression. Strategically, the unilateral fluctuation is large, so it is advisable to wait and see; short the EB - BZ spread when it is high [5]. - **Styrene**: Driven by previous exports, the port inventory of styrene continued to decline, and the circulating supply was limited. The short - term supply - demand situation was temporarily tight. Coupled with the shutdown of the Xuyang styrene plant and the reduction of the load of the Tianjin Bohua plant during the week, the styrene futures price continued to rise. However, currently, the styrene industry has good profits, and the overall start - up is stable, with active forward over - sales. The downstream industry's losses have expanded, and some plants have shut down, actively selling styrene raw materials and downstream product inventories. Overall, the short - term supply - demand of styrene is temporarily tight. Coupled with the overall strength of the chemical sector driven by the inflow of off - industry funds, the short - term increase in styrene is significant. However, there are no new positive factors in the short term, the downstream negative feedback is intensifying, and there are expectations of restarting the Sinopec Quanzhou and Tianjin Bohua plants next week. The short - term capital game has intensified, and caution should be exercised regarding the current increase. Strategically, it is advisable to wait and see unilaterally; short the EB - BZ spread when it is high [5]. Natural Rubber - On the supply side, the production in northern Thailand and north - central Vietnam is transitioning to a reduction and shutdown, with a shrinking total supply and rising overseas raw material prices, strengthening cost support. On the demand side, some semi - steel tire enterprises with a relatively high proportion of European exports have sufficient recent foreign trade orders, and their production has maintained a relatively high - level. Currently, the overall inventory reserve of enterprises has further increased, but domestic sales have been slow, mostly maintaining rigid - demand sales, and the overall sales pressure of enterprises remains high. In terms of inventory, China's natural rubber social inventory has continued the inventory accumulation trend. In summary, in the short term, driven by the strength of the synthetic rubber market, the natural rubber market has a strong bullish sentiment. However, considering the weak demand, it is expected that there is still significant upward pressure, with an operating range of 15,500 - 16,500 [6]. Polyolefins - Polyolefins were jointly driven by the rotation of funds into the chemical sector, geopolitical tensions, and the possible impact of the North American cold wave on supply, and their prices strengthened rapidly at the end of the week. From a static fundamental perspective, both supply and demand decreased, and inventory was destocked. The upstream inventory was low, and the price - holding intention was strong, but agents sold at a loss, the basis weakened significantly, and hedgers had no risk - free positions. Dynamically, for PP, due to many maintenance plans, the supply pressure has been relieved. Currently, the PDH profit is still low, and the production reduction drive is strong. In the later stage, attention should be paid to the implementation of marginal plant maintenance. For PE, the maintenance has decreased, and the import is expected to be under pressure. Some full - density plants have switched to LLD production, increasing the pressure on standard products, and the demand has entered the off - season, with the downstream start - up rate weakening. In terms of sentiment, the short - covering demand has been released, and the overall trading volume this week was weaker than last week [9]. PX, PTA, Ethylene Glycol, Short - Fiber, and Bottle Chips - **PX**: With high - profit margins, domestic and foreign PX plants have increased production, and currently, the PX load in Asia and China is at a historical high. In January, PX supply remained high. In terms of demand, as the Spring Festival approaches, the polyester production cut - back has expanded. The overall supply - demand of PX and PTA in the first quarter has weakened compared to expectations. It is expected that PX's own driving force will be limited before the Spring Festival. However, as PX trading switches to the March - April period, supported by tight supply - demand in the second quarter, the low - price support for PX is relatively strong. Last week, the cold wave in the US boosted overseas natural gas prices, which had a positive impact on some domestic chemical products (such as styrene, ethylene glycol, and some products with natural gas as raw material). At the same time, off - industry funds flowed into the chemical sector, driving up PX in the short term. However, the PX high point did not reach the mid - December high, and the physical PX market was slow to follow the increase. In the short - term weak supply - demand pattern of PX, caution should be exercised, and attention should be paid to the sustainability of funds. Strategically, pay attention to the resistance around 7,500 yuan/ton for PX, reduce long positions, and conduct mid - term rolling long - biased operations [11]. - **PTA**: Recently, there have been few changes in PTA plants. However, as the Spring Festival approaches, the polyester production cut - back has expanded, the PTA supply - demand has gradually weakened, and the spot basis has weakened. Recently, driven by the large - scale inflow of funds into the chemical sector and the expectation of improved PTA supply - demand in the second quarter, the PTA futures price has increased significantly, and the PTA futures processing margin has expanded significantly. However, due to the large inventory build - up pressure in February in advance, PTA's own driving force is limited before the Spring Festival. Caution should be exercised regarding the current increase. Strategically, pay attention to the resistance above 5,400 yuan/ton, and it is recommended to reduce long positions; conduct long - spread operations on the TA5 - 9 spread at low levels [11]. - **Ethylene Glycol**: The supply - demand of ethylene glycol shows a pattern of near - term weakness and long - term strength. In the near - term, ethylene glycol is still facing significant inventory build - up pressure. Since there are few domestic ethylene glycol plant maintenance plans from January to February, and with the commissioning of new plants such as Ningxia Changyi and BASF, the domestic ethylene glycol supply remains at a high level. At the same time, the polyester plant production cut - back and the seasonal weakening of terminal demand have weakened the demand support for ethylene glycol. From the information of arrived and forecasted shipping schedules, the reduction rate of ethylene glycol imports is slow, and the inventory build - up amplitude from January to February is expected to be high. However, in the long - term, the supply - demand of ethylene glycol is expected to improve in the second quarter, and inventory is expected to be reduced, mainly due to the shutdown of multiple large - scale domestic ethylene glycol plants and the spring maintenance of coal - based ethylene glycol plants, which will significantly reduce the supply expectation. Strategically, conduct long - spread operations on the EG5 - 9 spread at low levels; sell out - of - the - money put options EG2605 - P - 3800 at high levels [11]. - **Short - Fiber**: The overall supply - demand pattern of short - fiber is weak. Currently, the short - fiber supply remains at a high level. In terms of demand, as the Spring Festival approaches, downstream orders are gradually decreasing, and the number of yarn mills reducing or stopping production will increase around the end of the month. Recently, the sharp increase in the cost side has driven up the short - fiber price, and some downstream enterprises have followed up with replenishment. However, as the demand side weakens, the downstream is mostly waiting and seeing after the short - fiber price increase. The market will enter a digestion stage later. Overall, the absolute price driving force of short - fiber before the festival is weak, and it mainly follows the raw material price fluctuations. Strategically, the unilateral operation of PF03 is the same as that of PTA; the PF futures processing margin fluctuates between 800 - 1,000 yuan/ton, and it is advisable to short the spread when it is high [11]. - **Bottle Chips**: Recently, the implementation of maintenance plans for multiple polyester bottle - chip plants has been carried out one after another. In particular, a 1.2 - million - ton - per - year polyester bottle - chip plant in Jiangyin has been shut down since mid - January and will be under maintenance until March. There are still maintenance plans at the end of January. The domestic supply is expected to decrease significantly, and recently, the plants have continued to reduce inventory, supporting the processing margin. At the same time, the demand will weaken seasonally. With both supply and demand decreasing, it is expected that the absolute price and processing margin of bottle chips from January to February will still follow the cost - side fluctuations. Strategically, pay attention to the support around 6,200 yuan/ton for PR2603; the processing margin of the PR main contract is expected to fluctuate in the range of 400 - 550 yuan/ton; sell out - of - the - money put options PR2603 - P - 6200 at high levels [11]. Methanol - The methanol market has weak supply and demand. The inland plant inventory has decreased, but the high production volume restricts the rebound space, and the demand is expected to decline in the future. Although the port inventory has slightly decreased, the MTO demand is weak (many plants are under maintenance or have reduced loads), and the inventory reduction amplitude of the 05 contract has significantly weakened, suppressing the price rebound height. Currently, there are two key variables in the market: one is the reduction of imported methanol arrivals under the background of low methanol production in Iran. As of the latest data, the shipment volume from Iran is 350,000 tons; the other is the risk premium brought by geopolitical factors [13][14]. PVC and Caustic Soda - **Caustic Soda**: Last week, the prices of caustic soda in the mainstream regions continued to decline. The weekly average price of 32% caustic soda in Shandong was 633 yuan/ton, a month - on - month decrease of 6.36%. Low - price transactions frequently occurred during the week, impacting the market. The unloading of products by the main downstream enterprises was still difficult, and the order transactions were light. From the supply side, there were sporadic short - term shutdowns of chlor - alkali plants last week, but some chlor - alkali plants that had previously reduced loads resumed production, increasing the operating load rate. High - level operation combined with difficult sales led to continued inventory accumulation of caustic soda last week. On the demand side, the unloading situation of the two main downstream industries was poor. Under the strong chlorine situation, enterprises had no incentive to reduce production, and the problem of product backlogs at downstream enterprises continued. Under the weak supply - demand situation, the caustic soda price is under pressure in the short term and is still expected to decline. This week, the East China region faces monthly order contracts, and the supply - demand contradiction has not been alleviated. Coupled with the weak price transmission in the main regions, it is expected that the caustic soda market will continue to be weak [15]. - **PVC**: Last week, the domestic PVC price fluctuated after an increase, supported by positive economic expectations and bullish long - term expectations for commodities. The short - term increase in commodity prices in the market slightly pushed up the spot price. From the supply side, the operating load rate of the domestic PVC industry slightly decreased last week, and some enterprises had unplanned production cuts. However, the overall supply remained at a high level. The downstream production demand gradually weakened before the Spring Festival, and the foreign trade exports continued to be good but decreased in volume month - on - month. The inventory accumulation pressure before the festival in the industry continued. Currently, the macro - economic expectations are relatively strong, and combined with the strong PVC exports, the PVC price trend is relatively firm. However, as the Spring Festival approaches, some downstream enterprises are gradually on holiday, the industry inventory is accumulating rapidly, and combined with the weak support from raw material calcium carbide, the expected significant increase in price is limited. In the short term, the price may show a wide - range fluctuation pattern due to the cost support at the bottom and the supply - demand pressure at the top. It is expected that the PVC operating rate will continue to decline this week. Currently, some downstream enterprises are having pre - festival promotions, and the operating rate has increased. The export is expected to remain strong. However, considering that some downstream enterprises have started to take holidays one after another and the price of raw material calcium carbide is falling, it is expected that the PVC market will remain stable [15]. Urea - On January 23, the urea futures price fluctuated and closed higher, and the spot price increased slightly overall. Some regions raised their ex - factory quotes, but the downstream acceptance of the price was limited, and there were still some orders at low prices. New order transactions were relatively cautious. There are no planned maintenance enterprises this week. As the previously shut - down plants gradually resume production, the daily urea output fluctuates around the high level of 200,000 tons, and the short - term supply of goods is sufficient. In terms of demand, there is still some agricultural demand in the Jiangsu, Anhui, and Guangdong regions. The compound fertilizer industry is expected to reduce its operating rate due to the decrease in finished product sales volume. The operating rate of the board industry gradually decreases in the twelfth lunar month, and the overall industrial demand for urea has weakened. Urea inventory continued to decline this week, and the inventory reduction rhythm was faster than in previous years. This week, urea enterprises have successively launched the Spring Festival order - receiving plan, and it is expected that the inventory will be further reduced. Overall, the urea price is still restricted by the weak supply - demand situation, and the market transactions need to increase. However, the agricultural demand in some regions and the inventory reduction expectation have boosted market confidence. It is expected that the urea price will fluctuate in a wide range in the short term. The main urea contract should be watched in the range of 1,760 - 1,800 yuan/ton, and attention should be paid to the progress of downstream demand and the inventory reduction rhythm [16]. LPG - No specific views on the LPG market trend and investment strategies are provided in the LPG report. It only presents price, inventory, and operating rate data [17]. 3. Summaries According to Relevant Catalogs Crude Oil - **Price and Spread**: On January 23, Brent crude was at $64.06 per barrel, down $1.82 or 2.84% from January 22; WTI was at $59.36 per barrel, up $1.71 or 2.88

Market Sentiment Analysis - Since mid-December last year, A-share sentiment has been gradually rising, with a rapid increase since January, leading to a doubling of total trading volume and turnover rate from the lows [1] - The financing balance has increased at a rate similar to Q3 last year, but the financing balance as a percentage of circulating market value remains around 2.5%, and the proportion of financing purchases is about 11%, indicating no significant breakout from previous ranges [1] - There is a notable structural valuation differentiation in the market, with the valuation ratios of the CSI 500/1000 and CSI 300 reaching highs not seen since 2018, and technology growth sectors showing generally high valuations while consumer and financial sectors have lower valuation levels [1] - Despite the recent market uptrend, industrial capital reduction has not accelerated and remains at a moderate level, primarily concentrated in growth and manufacturing sectors [1] Polyester Filament Industry - Major filament manufacturers have decided to initiate a 15% production cut starting January 14 for one quarter, with the possibility of increasing the cut depending on market conditions [2] - As of January 16, the inventory days for mainstream POY in the filament industry are only 10 days, indicating a low level of stock; the weekly operating load for filaments is at 88.8%, down 1.4 percentage points week-on-week [2] - Domestic small and medium-sized direct-spun polyester filament enterprises are increasingly announcing shutdowns for the holiday period, which, combined with the production cuts, may lead to an operating load of around 71%-72% during the Spring Festival, marking the lowest level in nearly three years [2][3] - The peak of polyester filament capacity expansion has passed, with future new capacity mainly concentrated in major manufacturers like Tongkun and New Fengming [3] - Domestic demand is expected to gradually recover due to consumption stimulus policies, while external demand may maintain rapid growth due to factors like the Federal Reserve's interest rate cuts and India's cancellation of BIS certification [3] Profitability Outlook - The polyester filament industry is expected to maintain a relatively balanced supply-demand structure, allowing for good profitability through effective industry collaboration [3] - The planned large-scale production cuts by major filament manufacturers before and after the 2026 Spring Festival are anticipated to help keep inventories low, with expectations for demand peaks in March-April and overall price differentials for 2026 being promising [3]

1. Report Industry Investment Ratings - No industry investment ratings are provided in the reports. 2. Core Views of the Reports Polyolefins - Overall, the market is pressured by supply and seasonal demand, but the upside space may be limited due to cost support and profit compression. Attention should be paid to the actual changes in demand [1]. Methanol - The methanol futures are oscillating weakly. The mainland supply remains high, traditional demand is weak, and there is short - term pressure, but the long - term pressure may ease. The port inventory is slightly decreasing, but the MTO demand is weak, suppressing the price rebound [2]. Natural Rubber - Overseas raw material prices are falling, but considering Thailand's approaching low - production period, the raw material decline may be limited. The price is expected to fluctuate in the range of 15,500 - 16,500 [3]. Pure Benzene and Styrene - The supply - demand of pure benzene is slightly improving, but its own driving force is limited. Styrene is strong due to export and device issues, driving up the pure benzene price. Strategies include focusing on short - selling opportunities for BZ03 and narrowing the EB - BZ spread [4]. PVC and Caustic Soda - Caustic soda is expected to be stable and weak, and PVC is under pressure but has limited downward space due to cost support [5]. Urea - Urea prices are expected to be weak and oscillating in the short term, with supply remaining high and demand being cautious [6]. Glass and Soda Ash - Soda ash futures are expected to oscillate weakly in the short term, and glass is also expected to weaken, both can be treated bearishly [7]. Crude Oil - Short - term oil prices are affected by news, and the upside space is limited. Brent crude may oscillate between 60 - 66 dollars per barrel [8]. LPG - The LPG market shows price declines in some contracts and inventories. The downstream PDH开工率 has decreased [11]. PX, PTA, MEG, and Polyester Products - PX is expected to oscillate at a high level in the short term and be bullish in the medium term. PTA, short - fiber, and polyester bottle - chip follow the raw materials. MEG is expected to accumulate inventory significantly [13]. 3.
