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.

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 Summary 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core Views - **沪镍**: The overall view of Shanghai nickel is that it will oscillate. In the short - term, the spot trading is poor, the downstream purchases on a need - basis, the ore price may be under pressure, and the stainless steel has a certain negative impact on the nickel price. Although the new energy vehicle data is good, the medium - and long - term oversupply pattern remains unchanged. The basis is positive, but the inventory and the position situation are negative [2]. - **不锈钢**: The stainless steel is also expected to oscillate. The spot price is flat, the nickel ore price is falling, and the nickel iron price shows signs of stopping the decline. The basis is positive, but the inventory situation is negative [4]. 3. Summary by Directory 3.1 Nickel and Stainless Steel Price Overview - **沪镍**: On May 16, the closing price of the main contract of Shanghai nickel was 124,060, up 460 from the previous day. The nickel index on the Wuxi trading center was 124,000, down 1,050 [11]. - **不锈钢**: The average price of stainless steel was 13,887.5, and the price remained unchanged compared with the previous day [4]. 3.2 Nickel and Stainless Steel Inventory - **沪镍**: As of May 16, the LME nickel inventory was 195,222, a decrease of 3,924; the Shanghai Futures Exchange nickel warehouse receipts were 23,501, an increase of 157 [2][14]. - **不锈钢**: On May 16, the national stainless steel inventory was 1.1083 million tons, a decrease of 4,700 tons from the previous period.

Report Industry Investment Rating No relevant information provided. Report's Core View PVC and Caustic Soda - In the short term, the supply pressure of caustic soda is limited during the concentrated maintenance period, and the demand from the alumina sector has improved. Supported by fundamental supply - demand and positive macro - drivers, the spot price of caustic soda tends to be strong. However, attention should be paid to the price acceptance of non - aluminum sectors and the valuation of caustic soda. It is recommended to wait and see in the short term [7]. - For PVC, in the short term, the supply - demand contradiction is limited due to concentrated maintenance and limited inventory pressure. There is an expectation of rush - exporting PVC products. But in the medium and long term, there is an obvious over - supply pressure. It is recommended to wait and see, with a short - term rebound and a medium - term short - selling approach [7]. Polyester Industry Chain - For PX, in the short term, the supply is tight and the demand is supported, but the upward pressure on crude oil and the possible production cut of downstream products may put pressure on PX. It is recommended to treat it as a high - level shock, exit the PX09 - 1 positive spread, and pay attention to the reverse spread opportunity [12]. - For PTA, the short - term supply - demand is tight, but there is an expectation of weakening. It is recommended to treat it as a high - level shock, exit the TA09 - 1 positive spread at a high level, and pay attention to the reverse spread opportunity [12]. - For ethylene glycol, it is expected to reduce inventory in May, and it is recommended to take profit on the short - put option EG2509 - P - 4250 seller and conduct a long spread on EG9 - 1 [12]. - For short - fiber, the short - term inventory pressure is not large, but the processing fee is compressed. It is recommended to take the same strategy as PTA for single - side trading and expand the processing fee at a low level [12]. - For bottle - chips, the short - term supply - demand contradiction is not prominent, and the price follows the raw materials. It is recommended to pay attention to the opportunity of expanding the processing fee at the lower edge of the 350 - 550 yuan/ton range [12]. Styrene The short - term rebound of styrene is supported by low inventory and improved demand expectations. However, the high - production and high - inventory problems of 3S products and the poor supply - demand of pure benzene may limit the rebound height. It is recommended to pay attention to the resistance above 7800 - 7900 in the near - month [18]. Methanol The inland valuation of methanol has a downward pressure, the port starts the inventory - accumulation period, and the 09 contract is under pressure. It is recommended to short - sell the MA09 contract at a high level [22]. Crude Oil The overnight oil price continued to decline due to the progress of the US - Iran nuclear agreement negotiation. The short - term market will be mainly in a wide - range shock. It is recommended to wait and see in the short term and capture volatility - amplification opportunities in the option market [26]. PE and PP The spot sentiment of PE and PP has weakened. The supply pressure will gradually decrease in May, but the cost - end rebound compresses the profit. Attention should be paid to the restocking and exporting of plastic products [29]. Urea The core logic of the rise in urea futures is the boost of the clear export policy. The short - term supply - demand is expected to be tight, but the actual increase depends on the policy implementation and export orders. The short - term disk will be in a wide - range consolidation [90].
