市场情绪带动盘面反弹，但供需矛盾仍存

Report Industry Investment Rating - Not provided in the report Core Viewpoints - The futures prices of chemical products rose across the board yesterday. Driven by market sentiment, the olefin sector at the bottom rebounded. The strengthening support from the cost side also contributed to the rise. However, the supply - demand contradiction of polyolefins has not been alleviated, which may continue to suppress the market prices [3] - For PE, the supply remains high, and the demand is in the off - season, resulting in inventory accumulation and large de - stocking pressure. Although the cost support is strengthening, the supply - demand contradiction continues to suppress the price [3] - For PP, the short - term supply - demand fundamental variables are limited. The supply is still under pressure, and the demand is weak. The short - term rebound drive is limited, and attention should be paid to the cost - side disturbances and supply - side maintenance changes [4] Summary by Directory 1.
