1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - This week, the price of cis - butadiene rubber in the Shandong market of domestic cis - butadiene rubber fluctuated after rising, with the spot price ranging from 1,1400 to 1,1900 yuan/ton, and the price of high - cis cis - butadiene rubber of Sinopec Chemical Marketing and PetroChina sales companies increased by 300 - 400 yuan/ton in total [6]. - Recently, the cost supports the supply price of cis - butadiene rubber. The previously shut - down devices have not yet resumed stable production, and the inventory level continues to decline. Next week, some devices are expected to restart, and the domestic supply may increase significantly. Affected by the cautious sentiment of downstream and the production and sales pressure of downstream, the purchase in the market may be cautious, and the finished product inventory level is expected to rise [6]. - In terms of demand, the capacity utilization rate of domestic tires fluctuated slightly this week. Some large semi - steel tire enterprises had about a week of maintenance arrangements, which dragged down the overall enterprise capacity utilization rate. The shutdown sample enterprises of all - steel tires resumed work, and the current device production schedule has returned to the level before the shutdown, driving up the capacity utilization rate of all - steel tires. As the start - up of maintenance enterprises gradually recovers, there is still a small room for the capacity utilization rate to increase, but the current overall order performance is average, and enterprise production control will continue, which will drag down the increase in the overall capacity utilization rate [6]. - The short - term of the br2510 contract is expected to fluctuate in the range of 1,1700 - 1,2200 [6]. 3.
