1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - For polyethylene (PE), the cost support from crude oil is insufficient, the supply pressure is increasing, but the expected demand peak season has a certain support for prices, with limited downside space. Short - term prices may fluctuate and there may be a slight upward rebound opportunity. Consider selling put options [7]. - For polypropylene (PP), the cost - side support is unstable, the supply has an incremental expectation, but the downstream demand orders have a seasonal repair expectation, which supports prices. The price downside space is limited, short - term prices may fluctuate, and there may be a slight upward rebound opportunity. Consider selling put options [9]. 3.
