1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - The upstream US crude oil inventory has increased for three consecutive weeks, geopolitical conflicts have fluctuating impacts, and there is no definite upward driver for oil prices. The medium - to - long - term expectation of crude oil surplus is hard to be falsified, resulting in insufficient cost support for PX and PTA [7]. - For each product in the polyester industry chain, there are different supply - demand situations and profit trends. For example, PX has a high - level profit and high - level operation expected in the fourth quarter, while PTA has a risk of inventory accumulation, and MEG's supply - demand is expected to be loose in the fourth quarter [7]. 3. Summary According to Related Catalogs 3.1 Chapter 1: Comprehensive Analysis and Trading Strategies - PX&PTA: Upstream, oil price lacks upward drive, PX&PTA cost support is insufficient. PX has a back - structured spot floating price with changing monthly spreads, and its supply is abundant.
