Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - Recent resistance in raw material butadiene price support has weakened the cost support for cis - butadiene rubber. With the restart of most cis - butadiene rubber maintenance devices in mid - to - late July, supply is expected to increase. This week, under the boost of macro - sentiment, the mainstream supply price rose significantly, leading to a decrease in the inventory of cis - butadiene rubber production enterprises and a slight increase in trader inventory. After some devices restart next week, domestic supply is expected to increase, while downstream price - pressing procurement and wait - and - see sentiment may drive up production enterprise inventory. - Last week, the capacity utilization rates of domestic tire enterprises varied. The production of semi - steel tire enterprises that had maintenance at the beginning of the month gradually recovered, pulling up the overall capacity utilization rate of tire enterprises. The maintenance of individual all - steel tire enterprises slightly dragged down the all - steel tire capacity utilization rate. This week, the production of maintenance enterprises will return to normal, and there is room for a restorative increase in capacity utilization, which will drive up the overall capacity utilization rate of tire enterprises. - The br2509 contract is expected to fluctuate in the range of 11,300 - 11,800 in the short term [2]. 3.
