1. Report Industry Investment Rating - The report gives a cautious and bullish rating for both RU, NR, and BR [11] 2. Core Viewpoints of the Report - For natural rubber, the short - term supply pressure is not significant, raw material prices are rising slightly, and the cost - side support is strong. The downstream tire start - up rate is rising slightly, and the replacement demand will support natural rubber. NR is expected to perform better, and the price difference between RU and NR is expected to narrow [11] - For BR, although the price of butadiene has stagnated due to downstream load reduction, the core influencing factors remain unchanged. Supply is expected to decline, and with the support of raw material prices, the price of BR will remain strong [11] 3.
