The supply - demand fundamentals of both PE and PP are weak, and the rebound sustainability is limited. It is recommended to adopt a wait - and - see strategy for L and PP [3][4][5] 3. Summary by Relevant Catalogs 3.1 Market News and Important Data - Price and Basis: The closing price of the L main contract is 6,878 yuan/ton (-136), and that of the PP main contract is 6,714 yuan/ton (-110).

The supply is expected to increase due to the restart of many devices and more arriving imported resources, while the demand is in the off - season with a decline in overall downstream开工率. The supply - demand fundamentals are weakening, and the de - stocking pressure is large [3] - PP: The cost - side support of propane has declined, and international oil prices have dropped, causing the PP futures and spot prices to fall. The supply is difficult to be strongly supported, and the demand is in the off - season with limited new orders.
