Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - This week, the reduction in supply is gradually reflected. After the supply prices of butadiene rubber and butadiene are lowered, the spot offers gradually decline, which may drive some downstream enterprises to gradually stock up. The inventories of production enterprises and trading enterprises may decrease slightly [2]. - Last week, the capacity utilization rate of domestic tire enterprises increased significantly. Most enterprises that had maintenance at the beginning of the month have returned to normal levels, driving up the capacity utilization rate. It is expected that most enterprises will maintain their current production schedules this week to stock up for the "National Day" holiday and make up for previous order gaps. The overall capacity utilization rate will fluctuate slightly [2]. - The short - term price of the BR2511 contract is expected to fluctuate between 11,500 - 12,000 yuan/ton [2]. 3.
