Galaxy Securities mentioned that the valuation of the chemical industry is expected to gradually recover. The chemical industry's valuation is currently at a low level since 2014, and has medium- to long-term allocation value. Recent policy benefits have been rolled out successively, improving macroeconomic expectations, boosting investor confidence, and the valuation of the chemical industry is expected to gradually recover. Due to dual pressures of supply and demand, most chemical products have had a lackluster performance since the beginning of the year. Currently, there are still many ongoing construction projects in the chemical industry, and with the gradual realization of policy stimulus effects, terminal consumption of chemical products may improve, but it is expected that existing capacity and ongoing capacity will still need time to digest.
