Investment Rating - The industry investment rating is "Overweight" [3] Core Insights - The chemical industry is experiencing a dual drive of cyclical recovery and growth, with a focus on organic silicon, PTA, polyester filament, caprolactam, spandex, vitamins, sweeteners, refrigerants, and phosphorus chemicals [6] - The organic silicon industry is entering a recovery phase, with new applications becoming the core growth engine. From 2019 to 2024, domestic DMC capacity expanded rapidly, leading to temporary oversupply and declining prices. However, by 2025, no new capacity is expected, and demand from emerging sectors like new energy vehicles and photovoltaics is growing, improving the supply-demand balance [6] - The PTA/polyester filament industry is seeing a reduction in capacity expansion, with future growth concentrated among leading companies. Domestic demand continues to grow, and external demand is improving due to easing trade tensions [7] - The refrigerant market is entering a high prosperity cycle, driven by quota policies and stable demand growth from markets like Southeast Asia [8] - Synthetic biology is at a pivotal moment, with low-energy products expected to gain a longer growth window as traditional chemical companies adapt to energy costs and carbon taxes [9] - OLED technology is accelerating its penetration into larger displays, supported by government policies promoting the new display industry [10] - The demand for high-frequency and low-loss resins is increasing due to the rise of AI infrastructure and new applications like low-orbit satellite communication [11] - Electronic chemicals are benefiting from the expansion of wafer production capacity, with increasing demand driven by the growth of the semiconductor industry [12] Summary by Sections Industry Performance - The chemical sector ranked 8th in overall performance for the week of January 12-16, 2026, with a gain of 0.90% [21] - The top-performing sub-sectors included coal chemicals and carbon black, while modified plastics and titanium dioxide saw declines [22] Company Performance - The top three gaining companies for the week were Qicai Chemical (27.94%), Aladdin (20.24%), and Xinjin Road (15.50%) [26] - The top three losing companies were Zaiseng Technology (-26.65%), ST Jiaao (-18.42%), and Pulite (-17.28%) [29] Industry Dynamics - The National Development and Reform Commission is implementing measures to support the circular economy, emphasizing the importance of solid waste management and resource recycling [35]
