对二甲苯：单边震荡市，不追高，PTA：单边震荡市，不追高，MEG：新装置投产，库存继续累积，供应压力仍存

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - PX is in a unilateral volatile market, and it's not advisable to chase high prices. Overseas gasoline is in short supply with low inventory, and the strong cracking spread may last until the end of November, which drives PX valuation. However, downstream marginal demand is weakening, and supply is at a high level, so the upside space may be limited. Maintain reverse spread operation for the monthly spread [1][6]. - PTA is also in a unilateral volatile market, not recommended to chase high. It has cost support, but the upside space may be limited. Weaving domestic demand and new orders are weakening, and the polyester load is temporarily reduced. The cancellation of India's BIS certification is beneficial for filament exports. After load adjustment, the subsequent load will remain low, and the inventory accumulation pressure may be alleviated, but it will enter the inventory accumulation pattern again in December. Maintain 1 - 5 reverse spread operation [1][7][8]. - For MEG, new plants are put into operation, and inventory continues to accumulate, with supply pressure remaining. The domestic supply of ethylene glycol will further increase, and the inventory has continued to accumulate by 70,000 tons this week, and the unilateral basis trend remains weak [1][5][8].
