成本支撑叠加供需改善，短期震荡偏强运行

Report Industry Investment Rating - Not provided in the given content Core Views - Cost side: Affected by Trump's tariff exemption news, risk assets in the macro - level have stabilized temporarily, but related negotiations are at a stalemate, and market sentiment is cautious. The fundamentals of crude oil have limited marginal changes, with overall expectations slightly improved and support still existing [6]. - Supply side: Last week, the PTA capacity utilization rate decreased. Over the weekend, PTA plants such as Fujian Baihong and Yisheng Dahua restarted. Without new maintenance plans, the PTA operating rate is expected to rise this week [8]. - Production profit: Last week, the PTA production profit declined. Before the macro - pessimistic sentiment eases and there are no obvious positive signs on the demand side, the PTA production profit is unlikely to recover significantly [8]. - Inventory: Last week, the total PTA inventory continued to decline, but the available days of in - factory inventory increased. The raw material inventory of downstream polyester and the warehouse receipt inventory both decreased [8]. - Demand side: Last week, the polyester operating rate remained high, but the average available days of inventory increased, and the average production profit decreased [8]. - Overall logic: The cost - side support from crude oil remains. In terms of PTA supply and demand, supply decreased and demand remained high last week. The fundamentals are good, and the total inventory is continuously decreasing, but the pessimistic sentiment caused by tariffs has led to a decline in PTA processing fees. In the later stage, if there is no new maintenance for the restarted PTA plants last week, the operating rate will rise this week. Although the polyester on the demand side is at a seasonal high in operating rate, under the pressure of high inventory, insufficient orders, and compressed profits, the high operating rate is difficult to maintain in the long term. If the PTA operating rate continues to increase, supply and demand may turn weak. However, considering the cost - side support, the short - term PTA price is expected to fluctuate. The view is to take a wait - and - see attitude towards the short - term PTA price, with the reference range for the main contract being 4200 - 4500 [6][8][9].
