1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints of the Report - The market for ethylene glycol is currently in a state of cautious sentiment, with participants being more prudent due to uncertainties in macro - market developments and negotiations. The price of ethylene glycol has shown narrow - range adjustments, and the market is affected by factors such as supply - side losses and polyester load. In the short - term, the market will maintain a slow trend, and attention should be paid to polyester production reduction news [2]. - The production and sales of polyester products such as polyester filament, polyester staple fiber, and polyester chips have shown certain fluctuations. The production and sales of polyester filament have improved slightly, while the overall production and sales of polyester products are affected by factors such as raw material price increases [2]. 3.

Report Industry Investment Rating - The investment rating for PX/PTA/PF/PR is neutral [5] Core Viewpoints - The market's focus has been shifting between macro and geopolitical factors, with oil prices in a range - bound consolidation. Attention should be paid to the progress of the US - Iran nuclear talks and the Russia - Ukraine negotiations [2] - The gasoline crack has rebounded recently, but its seasonal performance is still weaker than in the previous two years. The aromatics blending demand for gasoline is not promising this year, and the intermittent blending demand at home and abroad can be basically met by naphtha [2] - PXN has rebounded from a low level due to macro - level positive factors and unexpected losses of multiple PX plants. In May, domestic PX maintenance plants will gradually restart, and PX will continue to draw down inventory under the commissioning of new PTA plants [2] - The PTA spot basis has weakened, and the processing fees have declined. With the high - operation of downstream polyester plants, PTA will continue to draw down inventory significantly in May. As the PTA price rebounds, the maintenance of PTA plants is postponed, and the supply will gradually return [3] - The polyester operating rate has increased, and downstream orders have improved after the positive progress of the China - US negotiations and tariff reduction. The inventory of filament has decreased significantly, and the average monthly polyester load in May may increase instead of decrease [3] - The spot processing fee of polyester bottle - chips has increased, and the market supply is gradually rising, which may put pressure on the market price. Attention should be paid to the maintenance news of bottle - chip plants due to rising costs [4] - After the continuous and rapid rise, the current valuations of PXN and PTA are no longer at low levels, and the market sentiment has declined. Attention should be paid to the downstream negative feedback and the support from the crude oil cost side [5] Summary by Directory Price and Basis - The report includes figures on the TA main - contract, basis, and inter - period spread trends; PX main - contract trends, basis, and inter - period spread; PTA East China spot basis; and short - fiber basis [9][10][12] Upstream Profits and Spreads - Figures cover PX processing fee (PXN), PTA spot processing fee, South Korean xylene isomerization profit, and South Korean STDP selective disproportionation profit [17][20] International Spreads and Import - Export Profits - It includes figures on the toluene US - Asia spread, toluene South Korea FOB - Japan naphtha CFR, and PTA export profit [25][27] Upstream PX and PTA Start - up - Figures show the operating rates of Chinese, South Korean, and Taiwanese PTA plants, as well as Chinese and Asian PX plants [28][31][33] Social Inventory and Warehouse Receipts - Figures present the weekly social inventory of PTA, monthly social inventory of PX, and various types of warehouse receipts for PTA, PX, and PF [36][39][40] Downstream Polyester Load - It includes figures on the production and sales of filament and short - fiber, polyester load, and the inventory days and profits of various filament products, as well as the operating rates of weaving, texturing, and dyeing in Jiangsu and Zhejiang [48][50][60] PF Detailed Data - Figures cover the load of polyester staple fiber, factory equity inventory days, physical and equity inventories, and the operating rates and processing fees of related yarns [71][73][80] PR Fundamental Detailed Data - Figures show the load of polyester bottle - chips, factory inventory days, processing fees, export profits, and various price spreads [91][93][99]

Report Industry Investment Ratings - Urea: ☆☆☆ (Three stars represent a clearer long/short trend, and there is still a relatively appropriate investment opportunity currently) [1] - Methanol: ☆☆☆ [1] - Styrene: ☆☆☆ [1] - Polypropylene: ☆☆☆ [1] - Plastic: ☆☆☆ [1] - PVC: ☆☆☆ [1] - Caustic Soda: ☆☆☆ [1] - PX: ☆☆☆ [1] - PTA: ☆☆☆ [1] - Ethylene Glycol: ☆☆☆ [1] - Short Fiber: ☆☆☆ [1] - Glass: ☆☆☆ [1] - Bottle Chip: ☆☆☆ [1] Core Views - The report analyzes the market conditions of various chemical products including urea, methanol, polyolefins, styrene, polyester, chlor-alkali, and glass soda ash, and provides investment ratings and trend judgments for each product [1][2][3][4][5][6][7][8] Summary by Product Methanol - The main contract of methanol has been continuously falling. Multiple domestic plants have resumed production, increasing supply pressure and causing enterprises to destock. Last week, the import volume decreased, and the MTO plant operating rate in Jiangsu and Zhejiang increased slightly, leading to destocking at ports. This week, the import volume is expected to increase significantly, domestic production is high, and some olefin plants remain shut down. In May, it is the traditional off - season for methanol, and both inland and port areas are expected to accumulate inventory, with a weak fundamental situation [2] Urea - The urea futures market is mainly in a volatile adjustment. As export news is digested, it returns to the fundamental trading logic. Last week, production enterprises significantly destocked, while ports accumulated inventory. New plants in Xinjiang have been put into operation, and supply remains sufficient. It is currently the domestic demand peak season with alternating industrial and agricultural demand. With the implementation of stable export measures, the bullish sentiment in the market is fading, and the price is expected to be weak in the short - term [3] Polyolefins - The main contracts of polyolefin futures continue to decline in a volatile manner. For polyethylene, PE plants are entering the maintenance period, and domestic supply is expected to decrease slightly. There is an expectation of improved foreign trade orders, but market sentiment is cautious. Some factories' finished - product inventories have decreased, but downstream demand is mainly for rigid orders, providing limited support for prices. For polypropylene, some export - oriented enterprises are restocking due to expected order increases, but the overall downstream recovery is limited, and it is difficult to drive prices up. As the temperature rises, order - taking is expected to worsen, and the operating rate of some factories may decline further [4] Styrene - The main contract of styrene futures closed down. There is an expected increase in domestic production and imports of pure benzene, and its price may be weak in the short - term, providing insufficient cost support for styrene. In terms of supply and demand, port inventory is low, and there is a need for restocking. Styrene prices vary by region, with improved transactions in the Shandong market after price corrections, while spot transactions are weak in other markets [5] Polyester - Oil prices fluctuated downwards. The restart of Zhongtai PTA and the expected polyester production cut dragged down PX and PTA, with significant declines in the monthly and basis spreads. The terminal market is recovering, and polyester filament enterprises' inventory pressure has eased, with a slight improvement in cash flow. In the short - term, if production cuts increase, upstream enterprises may give more concessions to downstream. In the medium - term, if orders improve, the industry chain profit may reach a new balance and enter a volatile stage. Also, attention should be paid to the gasoline demand peak season and changes in the aromatic hydrocarbon market. The profit of the ethylene glycol industry has improved, especially for the syngas method. There are many planned plant overhauls in the short - term, with a positive supply outlook. In the far - month, there will be supply pressure from the resumption of US imports and restart of overhauled plants. The monthly spread is strong, but if polyester production cuts due to losses are realized, it may drag down the market. Driven by falling costs, the price of short fiber fluctuated weakly. Under high - operating - rate pressure, the processing margin is low. As raw material prices fall, short fiber passively restores profits. Attention should be paid to the sustainability of processing margin restoration driven by changes in short - fiber supply. Bottle chip is in the peak demand season, with increasing production and stable inventory, but the industry processing margin is still low. If production cuts are implemented, consider entering the market at low prices to capture processing margin restoration [6] Chlor - Alkali - PVC continues to face pressure from weak demand and high supply, and its futures price remains weak. Some plants that were under maintenance are expected to resume operation this week, and supply is expected to increase slightly. Domestic demand is flat, and with the easing of tariffs, future product exports may improve. Due to weak domestic demand, the futures price may oscillate at a low level. After the spot price of caustic soda was raised, the delivery volume did not increase significantly. This week, chlor - alkali plants in East China are under maintenance, boosting the regional liquid caustic soda price. The profitability of chlor - alkali enterprises has recovered. Although downstream procurement prices have increased, the operating rates of alumina and viscose staple fiber have declined. Currently, the alumina price is rising, and it remains to be seen whether it can drive up the alumina operating rate. Downstream demand has not improved significantly, and the industry has restocked, so the futures price is expected to have limited upward momentum [7] Glass Soda Ash - Glass futures fluctuated narrowly. The sales in Shahe are okay, while the performance in other regions is average. Currently, inventory is concentrated in the upstream and mid - stream, with high pressure. With the upcoming rainy season, the industry faces shipment pressure. Upstream costs have decreased, and coal production lines still have profits, with production capacity operating at a narrow range. Processing orders have improved month - on - month but are still weak year - on - year, and downstream payment collection is poor. Currently, inventory pressure is high, and the driving force is weak. However, due to the low valuation and macro - factors, short - selling should be done with caution, and the futures price is expected to fluctuate with costs. Soda ash is in a weak state. Qinghai soda plants plan to conduct overhauls, while Yunxing has resumed operation, and Lianyungang has successfully produced products. Supply is fluctuating. The spot price is stable, and downstream purchasing sentiment is average. The rigid demand for heavy soda ash is under pressure, and there is a trend of inventory accumulation in the photovoltaic industry, leading to price declines. The subsequent ignition speed will slow down. In the short - term, due to overhauls, supply pressure has eased, and the futures price is expected to fluctuate with the cost side. In the long - term, under the supply - pressure pattern, attention should be paid to short - selling opportunities after rebounds [8]

Group 1 - The current bullish sentiment in the market is strong, particularly in the chemical futures sector, which continues to lead the gains [1] - Styrene prices are supported by tight spot liquidity due to maintenance, although they are still constrained by the low prices of pure benzene [1] - Short-term PTA spot prices are fluctuating strongly in line with the robust cost side [1]

Report Industry Investment Rating No relevant information provided. Core Viewpoints of the Report - PX: Short - term sideways market, month - to - month positive spread arbitrage. Long PX and short SC, long PX and short EB. The geopolitical conflict drives the rebound of crude oil, supporting PX valuation. The recovery of polyester terminal demand boosts the valuation of the aromatic polyester chain [10]. - PTA: Month - to - month positive spread arbitrage, long PTA and short SC. PTA supply decreases while demand increases, maintaining a de - stocking pattern. It is recommended to maintain the 6 - 9 positive spread arbitrage. Due to high processing fees, some device overhauls are postponed, so a short - on - rallies strategy is advisable [10]. - MEG: Unilateral trend is weak, long PTA and short MEG. Do not chase high on month spreads. Ethylene glycol supply will continue to increase, with difficulties in reducing port inventories [11]. Summary by Relevant Catalogs 1. Fundamental Tracking - **Price and Change**: On May 6, 2025, PX, PTA, MEG, PF, and SC had daily changes of - 1.3%, - 1.6%, - 0.6%, - 0.4%, and - 1.9% respectively compared to the previous day [2]. - **Month Spread**: On May 6, 2025, PX (9 - 1), PTA(6 - 9), MEG (9 - 1), PF(7 - 8), and PX - EB09 had daily changes of - 6, - 10, - 1, 12, and 24 respectively [2]. - **Inter - variety Spread**: On May 6, 2025, PTA09 - 0.65PX09, PTA09 - MEG09, PTA09 - PF09, PF07 processing fees, and PTA09 - LU09 had daily changes of - 19, - 47, 8, 9, and - 44 respectively [2]. - **Basis and Spread**: On May 6, 2025, PX basis, PTA basis, MEG basis, PF basis, and PX - naphtha spread had daily changes of 170, - 8, 4, 46, and 2 respectively [2]. - **Warehouse Receipts**: On May 6, 2025, PTA, ethylene glycol, short - fiber, PX, and SC warehouse receipts had daily changes of no change, - 3, - 80, 247, and no change respectively [2]. 2. Market Overview - **Crude Oil**: Israel plans to expand military operations in Gaza, and the geopolitical situation remains unstable. Iran is committed to diplomatic dialogue with the US, but the fourth - round nuclear negotiation is postponed [4]. - **PX**: On May 6, PX price rose, with two June Asian spot transactions at 745 and 746 respectively. A 210,000 - ton PX device in Japan stopped unexpectedly, and a 190,000 - ton device is under maintenance. A 2.5 - million - ton PX device in East China restarted. South Korea exported about 439,000 tons of PX in April, with 390,000 tons to China and 49,000 tons to Taiwan, China [4]. - **PTA**: A 1.5 - million - ton PTA device in East China stopped for planned maintenance and is expected to restart by the end of the month.

On the 6th, the MEG inventory at East China's major ports was about 790,000 tons, a decrease of 10,000 tons [8][9]. - **Polyester**: On May 6, the sales of direct - spinning polyester staple fiber factories were average, with an average sales - to - production ratio of 77%. The sales of polyester yarn in Jiangsu and Zhejiang were weak, with an average sales - to - production ratio of less than 40% in the afternoon [9][10]. 3. Trend Intensity - The trend intensities of p - xylene, PTA, and MEG are all 0 [11].

Report Industry Investment Ratings - No specific industry investment ratings are provided in the report. Core Views - The report provides views and strategies for various energy and chemical commodities, including PX, PTA, MEG, rubber, synthetic rubber, asphalt, LLDPE, PP, caustic soda, pulp, log, methanol, urea, styrene, soda ash, LPG, PVC, fuel oil, low-sulfur fuel oil, and container shipping index (European line). The overall market shows a mixed trend, with some commodities expected to be weak, some to be volatile, and some to have potential investment opportunities [2]. Summary by Commodity PX, PTA, MEG - **PX**: Cost collapse may lead to a post-holiday price decline. Suggest a long PX and short SC strategy. Supply is expected to increase while demand decreases, and the de-stocking rate may slow down [8]. - **PTA**: Cost support is weak. Suggest a long PTA and short SC strategy. Supply is decreasing while demand is increasing, and the de-stocking pattern continues. Consider a 6 - 9 positive spread operation [9]. - **MEG**: The unilateral trend is weak. Suggest a long PTA and short MEG strategy. Supply will continue to increase, and port inventory de-stocking is difficult [9]. Rubber - Expected to trade in a range. The market shows neutral trend strength, with changes in trading volume, open interest, and price differentials [10][11]. Synthetic Rubber - Expected to face downward pressure and trade in a range. Although the valuation provides some support, the driving force is downward due to the decline in crude oil prices during the holiday [14][16]. Asphalt - Expected to weaken following oil prices, with the crack spread likely to continue to recover. Current production capacity utilization has decreased, and inventory shows a mixed trend [17][29]. LLDPE - The trend is weak. Trade war impacts and high supply with weak demand are the main factors. New capacity is expected to be put into operation, and demand from downstream industries is limited [30][31]. PP - Prices have slightly declined, and trading volume has decreased. The market is weakly sorted, and downstream demand is flat after pre-holiday stocking [34][35]. Caustic Soda - Expected to trade in a range in the short term but face pressure later. Demand is in the off-season, and supply reduction is needed to balance the market [37][38]. Pulp - Expected to trade in a wide range. Port inventory is at a relatively high level, and downstream demand has not improved significantly [42][44]. Log - Expected to trade weakly in a range. The number of incoming ships and the volume of incoming goods have decreased [47][51]. Methanol - Expected to operate weakly. The market is in a pattern of high domestic production, high imports, high profits, and gradually increasing inventory [52][55]. Urea - Expected to trade in a range with increased support at the lower end. Production enterprise inventory may decline, and the futures market is expected to be volatile [57][58]. Styrene - Expected to trade weakly. The pure benzene market is in a pattern of increasing supply and weakening demand, and downstream negative feedback is expected to be transmitted [60][61]. Soda Ash - The spot market shows little change. The market is expected to be stable to slightly strong in the short term, with stable production and weak downstream demand [63][65]. LPG - The support from crude oil is weakening. Pay attention to the inter-month positive spread strategy. The market shows neutral trend strength, with changes in production capacity utilization [67][74]. PVC - Expected to trade weakly. High production and high inventory structure are difficult to alleviate in the short term, and the market is under pressure from supply and demand [76][77]. Fuel Oil and Low-Sulfur Fuel Oil - **Fuel Oil**: The external spot price has dropped significantly, and the short-term trend is expected to weaken further. - **Low-Sulfur Fuel Oil**: It has slightly corrected following crude oil, and the spread between high and low sulfur in the external market has widened [80]. Container Shipping Index (European Line) - Expected to trade at a low level in a range. Hold a light short position in the 10 - 12 reverse spread [82].

Report Industry Investment Rating - Not provided in the content Core Viewpoints - Trump's attitude towards China's tariffs has eased, but the issue remains unresolved. Direct textile and clothing orders to the US are still on hold, and the expectation of polyester production cuts suppresses market sentiment. PX and PTA maintain low valuations and inventory reduction, but the rebound is limited due to weak gasoline and demand expectations. The 5 - 9 month spread has strengthened recently, and attention should be paid to crude oil and macro - changes [1] - For short - fiber, the US tariff situation is improving, market sentiment is stable, but the willingness to chase high prices is insufficient. Some yarn mills plan to have holidays during the May Day period, and the raw material stocking intention is average, with the market in a volatile consolidation [1] - For PR, the tariff policy has little impact on bottle - chip demand. The bottle - chip load has returned to a high level, and the processing margin of bottle - chip factories is limited. The market price is expected to follow the raw material cost [1] Summary by Directory Price and Basis - Relevant figures include TA main contract & basis & inter - period spread trend, PX main contract trend & basis & inter - period spread, PTA East China spot basis, and short - fiber 1.56D*38mm semi - bright natural white basis [10][11][13] Upstream Profit and Spread - Figures cover PX processing fee PXN, PTA spot processing fee, South Korean xylene isomerization profit, and South Korean STDP selective disproportionation profit [18][21] International Spread and Import - Export Profit - Include toluene US - Asia spread, toluene South Korea FOB - Japan naphtha CFR, and PTA export profit [26][28] Upstream PX and PTA Start - up - Show China PTA load, South Korea PTA load, Taiwan PTA load, China PX load, and Asian PX load [29][32][33] Social Inventory and Warehouse Receipts - Comprise PTA weekly social inventory, PX monthly social inventory, PTA total warehouse receipts + forecast volume, PTA warehouse warehouse receipts inventory, PX warehouse receipts inventory, and PF warehouse receipts inventory [37][40][41] Downstream Polyester Load - Include filament production and sales, short - fiber production and sales, polyester load, direct - spinning filament load, polyester staple fiber load, polyester bottle - chip load, filament factory inventory days, and Jiangsu and Zhejiang loom, texturing, and dyeing start - up rates [48][50][60] PF Detailed Data - Include polyester staple fiber load, polyester staple fiber factory equity inventory days, 1.4D physical inventory, 1.4D equity inventory, recycled cotton - type staple fiber load, raw - recycled spread, pure polyester yarn start - up rate, pure polyester yarn production profit, polyester - cotton yarn start - up rate, and polyester - cotton yarn processing fee [70][72][83] PR Fundamental Detailed Data - Include polyester bottle - chip load, bottle - chip factory bottle - chip inventory days, bottle - chip spot processing fee, bottle - chip export processing fee, bottle - chip export profit, East China water bottle - chip - recycled 3A - grade white bottle - chip spread, bottle - chip next - month spread, and bottle - chip next - next - month spread [91][93][101] Strategy - Unilateral: The short - term market sentiment has improved, and PX/PTA/PF/PR are stable [5] - Cross - variety: None [5] - Cross - period: None [5]
