The supply - demand structure is weak, and the de - stocking pressure may limit the rebound space [3]. Strategy - **Single - sided**: Adopt a wait - and - see approach for L/PP. The short - term cost - side fluctuations are strong, and the macro - and capital - side disturbances are increasing. The current supply - demand fundamentals of polyolefins are weak, and the sustainability of the rebound may be limited [4]. - **Inter - period**: No strategy is provided [5]. - **Inter - variety**: No strategy is provided [5].

Report Investment Rating - No investment rating information provided in the report. Core View - The report indicates that in the short - term, there is a small rebound due to cost - end support and sentiment boost. However, for PE, the supply is increasing while demand is weak, leading to inventory accumulation and high de - stocking pressure. For PP, the supply is still relatively loose, demand is weak, and the inventory level is high. The cost end, with the recent rebound of international oil prices and propane prices, provides some support, but the overall price is still under pressure from supply - demand contradictions [3][4].

1. Industry Investment Rating No investment rating provided in the report. 2. Core Viewpoints - The demand in the polyolefin market continues to be weak, and the market is oscillating weakly. For PE, the supply pressure remains due to the expected increase in the start - up rate and the approaching of the demand off - season, leading to a pattern of increasing supply and weakening demand. For PP, the weak supply - demand situation persists in the short term, with inventory accumulating and the demand side lacking follow - up [1][2][3]. - The recommended strategy is to remain on the sidelines for single - side trading, with the market expected to be weakly oscillating in the short term. For inter - period trading, conduct a reverse spread on the L01 - 05 contract when the price is high. For inter - variety trading, narrow the L - P price spread when it is high [4]. 3.

Report Summary 1. Investment Rating The report does not provide an industry investment rating. 2. Core Views - **PE**: Affected by geopolitics and macro - factors, international oil prices have rebounded strongly from a low level, enhancing cost support. However, the supply is expected to increase, and downstream demand follows up limitedly. Although the price has risen with cost support, the upside space is limited due to supply - demand pressure [2]. - **PP**: Oil prices and propane prices have rebounded, increasing cost support. But the supply pressure still exists, and the demand follows up slowly with large inventory de - stocking pressure. The price increase may not be sustainable [3]. 3.
