1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The polyolefin market continues to be weak, with PE and PP prices under pressure due to factors such as supply - demand imbalances and weakening cost support [1][2][3] - For PE, the continuous decline is due to loose supply - demand fundamentals, post - holiday inventory accumulation, and weakening cost support from falling crude oil prices. For PP, the weakening is dragged down by falling crude oil and propane prices, along with a loose supply - demand pattern [2][3] - The report suggests a wait - and - see approach for single - side trading, and provides strategies for inter - period and inter - variety trading [4] 3.
