Report Industry Investment Rating - No information provided on the industry investment rating Core View of the Report - Pure benzene port inventory decreased slightly, but its basis and processing fee continued to be weak. Domestic production capacity utilization of pure benzene has bottomed out and rebounded, with the impact of previous sanctions on refinery operations easing, and the pressure of incoming shipments increasing intermittently. Downstream demand remained weak, with styrene in concentrated maintenance, phenol production declining again, CPL production at a low level, and adipic acid production rebounding [2]. - Styrene ports continued to experience a slight reduction in inventory, with short - term low - level production capacity utilization, and maintenance only decreasing at the end of November. EB factory inventory further decreased, and port inventory began to decline. However, attention should be paid to downstream demand, as EPS production capacity utilization dropped rapidly, ABS and PS production capacity utilization remained low, and the inventory of the three major hard plastics only slightly decreased from high levels [2]. Summary by Directory 1. Pure Benzene and EB's Basis Structure, Inter - period Spreads - Figures related to pure benzene basis and inter - period spreads include the pure benzene main contract basis, pure benzene spot - M2 paper cargo spread, and pure benzene continuous first - contract to continuous third - contract spread [7][10]. - Figures related to EB basis and inter - period spreads include the EB main contract basis and the styrene continuous first - contract to continuous third - contract spread [15][18]. 2. Pure Benzene and Styrene Production Profits, Domestic - Foreign Spreads - Figures related to production profits and spreads include styrene non - integrated production profit, pure benzene FOB US Gulf - FOB South Korea spread, naphtha processing fee, pure benzene FOB South Korea - naphtha CFR Japan spread, pure benzene import profit, and styrene import profit [21][24][33]. 3. Pure Benzene and Styrene Inventory, Production Capacity Utilization - For pure benzene, figures show the East China port inventory and production capacity utilization [39]. - For styrene, figures cover the East China port inventory, production capacity utilization, East China commercial inventory, and factory inventory [42][44]. 4. Styrene Downstream Production Capacity Utilization and Production Profits - Figures display the production capacity utilization and production profits of EPS, PS, and ABS [52][53][57]. 5. Pure Benzene Downstream Production Capacity Utilization and Production Profits - Figures show the production capacity utilization and production profits of caprolactam, phenol - ketone, aniline, adipic acid, and other downstream products [60][68][73]. Strategy - Unilateral: No strategy provided [3]. - Basis and Inter - period: Consider a long - short spread strategy for EB2512 - EB2601 at low prices and a short - long spread strategy for BZ2603 - BZ2605 at high prices [3]. - Cross - variety: No strategy provided [3].
