Report Summary 1) Report Industry Investment Rating - No specific industry investment rating is provided in the report. 2) Core View of the Report - The synthetic rubber market will operate in a short - term oscillation due to the intensification of the contradiction between fundamentals and macro - sentiment. The fundamental pressure has increased significantly, but macro - expectations provide support. The market presents a pattern of increasing supply and demand, with the supply growth rate higher than the demand growth rate, leading to an increase in inventory pressure for cis - butadiene rubber. The high processing profit on the cis - butadiene rubber disk is unsustainable, and the cost side of cis - butadiene rubber is also under pressure. However, there are expectations of a preventive interest rate cut by the Fed and long - term policy support from China's anti - involution policy, which support the market. Overall, the market will oscillate widely within the fundamental valuation range [2][3]. 3) Summary by Relevant Catalogs a.
