Report Summary 1. Report Industry Investment Rating - No investment rating provided in the report. 2. Core Viewpoints - **PTA**: Near - term TA开工 is gradually rising, polyester开工 is further declining due to bottle - chip production cuts, inventory is decreasing, and the basis is oscillating strongly with improved spot processing fees. PX domestic and overseas maintenance is returning,开工 is rising, PXN and its structure are weakening. With downstream decline and bottle - chip contradictions remaining, and new TA devices approaching operation, an inventory inflection point is near. Consider shorting processing fees at high levels [2]. - **MEG**: Near - term domestic maintenance and restarts co - exist, overall开工 is basically flat, port inventory is continuously decreasing due to low arrivals, downstream stocking levels are slightly falling, the basis is slightly weakening, and profitability remains high. Although near - term inventory is decreasing under oil - based large - device rotation maintenance, the monthly spread is greatly affected by warehouse receipts, and the absolute valuation is not low [2]. - **Polyester Staple Fiber**: Near - term production cuts by Sanfangxiang and Jiangnan have led to a slight decline in开工 to 92.1%, sales are stable, and inventory is slightly accumulating. On the demand side, polyester yarn开工 is stable, raw material stocking is flat, finished - product inventory is increasing, and profitability is oscillating at a low level. With a slight decline in staple - fiber supply and an improvement in profitability due to polyester开工 decline caused by bottle - chip production cuts, but without obvious downstream improvement, profitability is expected to remain weak [2]. - **Natural Rubber & 20 - grade Rubber**: The main contradictions are that the national explicit inventory is slightly decreasing with an absolute level not being high, the price of Thai cup - lump rubber is slightly rebounding with expected good tapping enthusiasm, and the trade war is easing. The strategy is to wait and see [3]. 3. Summary by Product PTA - **Price and Margin Changes**: From June 3 to June 9, crude oil rose by $0.5 to $67.0, PTA spot price dropped by $80 to $6850, and the processing fee increased by $2.

Natural Rubber & 20 - grade Rubber - **Price Changes**: From June 3 to June 9, the US - dollar - denominated Thai standard rubber spot price remained at $1680, and the Shanghai full - latex rubber price rose by $320 to $13125 [3]. - **Other Indicators**: The national explicit inventory slightly decreased, and the price of Thai cup - lump rubber slightly rebounded [3]. Styrene - **Price and Margin Changes**: From June 3 to June 9, the ethylene price remained at $780, the pure - benzene price in East China rose by $65 to $5920, and the styrene domestic profit remained at $138, while the EPS domestic profit dropped by $145 to $285 [6].
