1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - The short - term rainy weather in the production areas continues to affect the release of new rubber, the raw material trend is strong, and the cost support is strong. There is still a bullish sentiment in the market. However, according to Longzhong, downstream enterprises may control production in late August, and the de - stocking speed of spot inventory is expected to slow down, which may suppress the price rebound. Under the game of supply and demand, it is expected that the short - term natural rubber price will maintain a range - bound consolidation [80][81]. 3.
