1. Report Industry Investment Rating - The rating for RU and NR is neutral. The rating for BR is also neutral [5] 2. Core Viewpoints of the Report - For natural rubber, with increased rainfall in major production areas, raw material output is expected to be limited, strengthening cost - side support. Domestic imports are expected to remain stable. Downstream demand lacks highlights, and tire factory operating rates are unlikely to rise. Rubber prices are expected to have support at the lower end [5] - For BR, supply may increase slightly, and downstream demand has no highlights. The overall supply - demand pattern is weak. The downward space depends on the price fluctuation of upstream butadiene. BR may follow the raw material price down, but the strong natural rubber price and continuous tire replacement demand provide some support [5] 3.
