Report Summary 1. Industry Investment Rating No investment rating information is provided in the report. 2. Core Viewpoints - The market anticipates a weakening in pre - holiday demand. For PE, due to the decline in international oil prices, the cost - side support for plastics has weakened. With an increase in supply and a decrease in demand, the polyolefin market has corrected. For PP, the cost - side support of propane and oil has declined, and the market sentiment is cautious, leading to a correction in both futures and spot prices [2][3]. - The current supply - demand fundamentals of polyolefins are weak. For PE, there is an expected increase in supply pressure, and downstream demand is in the off - season with weak order follow - up. For PP, the supply side lacks strong support, and demand is expected to decline seasonally. The market is affected by cost - side and macro - sentiment fluctuations, and the sustainability of the rebound is limited. The report recommends a wait - and - see approach for L/PP [2][3][4]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoint of the Report - The fundamentals of pure benzene continue to improve, with port inventories declining from their peak in the first week and downstream提货 demand being boosted. Although the styrene startup rate remains low, the startup rates of non - styrene pure benzene downstream industries have rebounded, and attention should be paid to the sustainability of the improvement in downstream startup rates. Overseas, attention should be paid to the implementation progress of the expected reduction of the US tariff policy on South Korean pure benzene. The domestic pure benzene startup rate remains low. - For styrene, the port inventory is still slightly decreasing at the beginning of the week, and the port basis is slightly strengthening. The recovery rate of styrene startup is still slow, the resumption of production at Bohua is still to be determined, and Zhenhai Liande continues to be shut down. The downstream startup rate has increased, with the EPS startup rate rising above the seasonal level, the PS startup rate declining seasonally, and the ABS startup rate consolidating at a low level. Overall, the weighted downstream startup rate has increased, and the ABS inventory pressure has gradually eased [3]. 3.

1. Report Industry Investment Rating - No information provided regarding the report industry investment rating 2. Core Views of the Report - PE: Despite a short - term rebound in the PE price driven by the sharp rise in coking coal and coke futures prices and cost - side disturbances, the improvement in the PE supply - demand fundamentals is limited. There is still supply pressure due to new device production and expected increase in low - cost imported goods, and the demand side remains weak as downstream industries are in the off - season. However, the short - term inventory pressure has been slightly alleviated [2] - PP: The PP price continues to rebound due to the warming market sentiment, supply reduction expectations, and cost - side support. But there are still supply - demand contradictions. The sustainability of the short - term rebound depends on the scale of upstream device maintenance, and the price rebound space is expected to be limited due to insufficient demand improvement [3] - Strategy: It is recommended to take a wait - and - see approach for both LLDPE and PP. Continue to monitor the implementation of upstream device maintenance, as the short - term supply - demand contradictions have not been improved, while geopolitical tensions are increasing cost - side disturbances and the strengthening of the coal sector is driving up market sentiment [4] 3. Summary According to the Directory 3.1 Market News and Key Data - Price and Basis: The closing price of the L main contract is 6,628 yuan/ton (-14), and that of the PP main contract is 6,484 yuan/ton (-2). The LL spot prices in North and East China are 6,520 yuan/ton (+20) and 6,600 yuan/ton (+70) respectively, and the PP spot price in East China is 6,250 yuan/ton (+0).

1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints - For PE, short - term sentiment boost and cost - side disturbances drive the price to stop falling and rebound, but limited improvement in supply - demand fundamentals restricts the rebound space. The supply pressure increases due to new device production, limited planned maintenance, and expected increase in low - price imported goods, while the demand is weak as it's the off - season, and the downstream开工 rate continues to decline [1][2]. - For PP, short - term market sentiment turning warm, supply - side shrinkage expectations, and cost - side support drive the price to stop falling and rebound. However, the supply - demand contradiction is large, with high inventory levels. The short - term rebound depends on the increase in supply - side maintenance scale, but the price rebound space may be limited due to insufficient demand improvement [1][3]. 3. Summary by Directory 3.1 Market News and Important Data - Price and basis: L main contract closed at 6449 yuan/ton (-23), PP main contract at 6330 yuan/ton (-18).

New device production and expected increase in imports increase supply, while downstream demand remains weak as it's the off - season, and the开工 rate is expected to decline further [2]. - **PP**: Market sentiment, supply - side expectations, and cost support drive the price to rebound. However, the supply - demand contradiction is large, with high inventory and limited downstream demand improvement [3]. 3.3 Strategy - Unilateral: LLDPE and PP are under the "wait - and - see" strategy. The short - term may continue the volatile trend, and attention should be paid to the implementation of upstream device maintenance [4]. - Inter - period: Not provided - Inter - variety: Short the spread of L05 - PP05 when it is high [4]

Report Industry Investment Rating - Unilateral: Neutral [3] - Inter-period: None [3] - Inter-variety: None [3] Core Viewpoints of the Report - The ethylene glycol (EG) market continues to accumulate inventory, and prices are consolidating at low levels. The current price is not high, but the downstream implicit inventory has also accumulated to a high level. With the increase in port inventory, the liquidity of goods in the market has increased. In addition, the production pressure is relatively large, and the inventory accumulation pressure from January to February remains relatively high, limiting the rebound space [1][3] - On the domestic supply side, the reduction of syngas-based production load is not obvious, and the domestic ethylene glycol load has rebounded to a high level of over 70%. The inventory accumulation pressure remains high under the high supply from January to February and the weakening demand. Overseas, with the maintenance of plants in Saudi Arabia and Taiwan, the import pressure will ease after February. On the demand side, weaving orders have weakened marginally, the load has declined rapidly, and the polyester load has declined slightly due to weakening profitability [2] Summary by Relevant Catalogs Price and Basis - The closing price of the main EG contract yesterday was 3,847 yuan/ton, a change of +30 yuan/ton (+0.79%) from the previous trading day. The spot price of EG in the East China market was 3,702 yuan/ton, a change of +19 yuan/ton (+0.52%) from the previous trading day. The spot basis of EG in East China was -139 yuan/ton, a decrease of -3 yuan/ton month-on-month [1] Production Profit and Operating Rate - According to Longzhong data, the production profit of ethylene-based EG was -$87/ton, a month-on-month change of +$0/ton. The production profit of coal-based syngas EG was -841 yuan/ton, a month-on-month increase of +16 yuan/ton [1] International Price Difference - No specific data provided Downstream Sales and Production and Operating Rate - Weaving orders have weakened marginally, the load has declined rapidly, and the polyester load has declined slightly due to weakening profitability [2] Inventory Data - According to CCF data released every Monday, the inventory of MEG at the main ports in East China was 844,000 tons, a month-on-month increase of 25,000 tons. According to Longzhong data released every Thursday, the inventory of MEG at the main ports in East China was 645,000 tons, a month-on-month increase of 28,000 tons. According to CCF data, the total planned arrivals at the main ports in East China last week were 106,000 tons, and the arrivals at the secondary ports were 25,000 tons. This week, the total planned arrivals at the main ports in East China are 106,000 tons, and the arrivals at the secondary ports are 43,000 tons. The overall situation is slightly on the high side, and it is expected that the main ports will have a slight inventory accumulation [1]

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report Plastic Part - The price of plastics is under pressure due to abundant supply. The total effective capacity growth rate is 16%, and the domestic production volume growth rate is 18% in the first half of the year. Although imports have declined year - on - year, the ample supply still suppresses prices. The overall market situation is not optimistic, with a pattern of increasing supply and decreasing demand before the Spring Festival [5]. - The strategy suggests a short - position allocation on rebounds for single - side trading. Cross - period and cross - variety trading are not recommended for now [5]. Polypropylene Part - Polypropylene prices are under pressure in the off - season. The total effective capacity growth rate is 12.7%, and the estimated annual output growth rate is 16.7%. The market is expected to enter a pattern of increasing supply and decreasing demand in Q4, with an unfavorable supply - demand situation [95]. - Similar to plastics, the strategy recommends a short - position allocation on rebounds for single - side trading. Cross - period and cross - variety trading are also not recommended currently [97]. 3. Summaries Based on Relevant Catalogs Plastic Part Price & Spread - The basis has weakened significantly as the spot price increases less than the futures price. The 5 - 9 month spread has strengthened to - 31, and the warehouse receipts remain at a high level [5]. - The import window has improved, and the LD import profit is at a relatively high level within the year. The non - standard price spread shows that the HD film supply is tight, and the LD has weakened recently [29][32]. Supply - New capacity has been concentratedly put into operation from the end of 2024 to the first half of 2025, with a nominal capacity growth rate of 19.2% and an effective capacity growth rate of 16.7%. The supply is expected to remain abundant, with a slight decline in the short term and an increase in the future [47]. - The overall inventory removal is not smooth, and the inventory has been transferred to the middle - stream. The subsequent supply increase and weak downstream confidence may lead to a slowdown in social inventory removal [5]. Demand & Inventory - The demand for downstream industries such as agricultural films and packaging films has entered a phased off - season. The overall downstream demand shows signs of decline, and the raw material demand is expected to decrease [5]. - The inventory transfer to the middle - stream is not smooth, and the downstream's lack of confidence in the future market has led to a slowdown in social inventory removal [5]. Polypropylene Part Price & Spread - The basis has weakened as the futures price rebounds, and the warehouse receipts have increased again. The cross - period spread is fluctuating [97]. - The import window is approaching closure, and the export profit to Southeast Asia has limited growth.
