Investment Rating - The report maintains a "Buy" rating for the companies mentioned, indicating a positive outlook for their stock performance in relation to the market index [4]. Core Insights - The chemical industry is expected to experience price increases due to improved supply-demand dynamics and a "de-involution" policy that encourages companies to avoid price wars and focus on profitability [10][22]. - The manufacturing sector shows signs of recovery, with the PMI reaching 50.1% in December 2025, indicating a return to expansion [16][22]. - The inventory cycle is shifting from active destocking to passive destocking, which may lead to rapid inventory depletion in the chemical sector once demand improves [22]. Summary by Sections Supply and Demand Dynamics - The investment growth rate in the chemical raw materials and products manufacturing industry has been declining since 2022, with a projected drop to negative growth by June 2025 [15]. - The supply side is improving due to reduced new capacity and the shutdown of older facilities in Europe and Japan, particularly affecting basic chemicals like ethylene and propylene [15][22]. Policy Impact - The "de-involution" policy initiated by the central government aims to prevent vicious competition, leading to a consensus among leading companies to maintain prices by reducing production rates [22][10]. Company-Specific Insights - **China Chemical**: The company has a production capacity of 200,000 tons for both adiponitrile and caprolactam. Price rebounds in these products are expected to significantly enhance its earnings [23]. - **Sanhua Chemical**: The company is positioned to benefit from price recovery in its core products, with a strong focus on expanding its high-end cellulose product lines [30]. - **Donghua Technology**: The company has multiple high-end chemical projects that are expected to improve profitability as supply constraints stabilize prices [37]. - **Southeast Network Frame**: The company produces 500,000 tons of polyester filament, with potential for revenue growth as raw material prices recover [41]. Investment Recommendations - The report highlights key companies to watch, including China Chemical, Sanhua Chemical, Donghua Technology, and Southeast Network Frame, all of which are expected to benefit from the anticipated price increases in chemical products [10][45].
