Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core Viewpoints of the Report - The demand continues to be weak, suppressing the rebound space. For PE, the supply is high, the demand is in the off - season, the inventory is accumulating, and the price is suppressed by the supply - demand contradiction. For PP, the short - term supply - demand fundamentals have limited variables, the demand is weak, and the short - term rebound drive is limited. The current cost and supply - demand contradictions are in a game, and the upward drive is insufficient, so the expected rebound height is limited [1][2][3][4] Group 3: Summary by Directory 1.

Polyolefin Inventory - Not provided in the content Group 4: Strategies - Unilateral: Wait and see. Currently, there is a game between the cost side and the supply - demand contradiction. With insufficient upward drive, the expected rebound height may be limited. - Inter - period: None - Inter - variety: Short the spread of L05 - PP05 when it is high [4]
