1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - Recently, due to unplanned production cuts in some styrene plants and maintenance plans from September to October, the supply of styrene has shrunk. Driven by peak - season demand in the downstream EPS/PS industries, overall operations have slightly improved, raw material procurement has followed up, and demand support has strengthened. However, although port inventories continue the downward trend from high levels, the current inventory level may still limit the upside potential of prices. Additionally, attention should be paid to the potential impact of macro - policies and geopolitical factors on the commodity market. The strategy is to take a short - term low - buying approach for EB10, and pay attention to the pressure around 7200; widen the spread between EB11 and BZ11 at low levels [2]. - Recently, the restart of some pure benzene plants has led to a month - on - month increase in production, and the supply side remains at a relatively high level. The demand side is sluggish, with unplanned production cuts in some styrene plants and a general weakening of the operating rates in other downstream industries. The supply - demand pattern of pure benzene remains loose, and the pre - holiday stocking demand has not been significantly released, resulting in weak overall market drivers. In the short term, price trends may be easily affected by geopolitical and macro factors. The strategy is for BZ2603 to fluctuate in tandem with styrene [2]. 3.
