1. Report Industry Investment Rating No specific industry investment rating is provided in the report. 2. Core Views of the Report - Beijing optimized and adjusted housing purchase restriction policies, and "Qiushi" emphasized that real - estate policies should not adopt a piecemeal approach. The continuous introduction of real - estate policies further supports demand, and the pace of subsequent policy introduction may accelerate. Although the new construction of the real - estate chain still faces multiple pressures, the industry bottom is approaching as the base gradually decreases. Sales data (new + second - hand houses) remains the leading indicator for driving the sector's valuation [3][7]. - Anti - involution is the main line for cyclical products. In the new field, attention should be paid to electronic cloth, clean rooms, and commercial aerospace. For the cement and glass industries, the effective reduction of supply is the key point to observe in the next stage. The glass fiber sector has relatively good profitability, and there is a possibility of a staged price increase. In the new field, the high - growth of the AI supply chain in 26H1 is the most certain direction, and the semiconductor/storage capital expenditure at home and abroad drives the performance and valuation of the clean - room sector. The theme investment in commercial aerospace is constantly catalyzed [4][8]. 3. Summary According to the Directory 3.1 Anti - involution is the Main Line for Cyclical Products, and Attention is Paid to Electronic Cloth, Clean Rooms, and Commercial Aerospace in the New Field - **Real - estate Policy**: On December 24, 2025, Beijing optimized real - estate policies, including relaxing the conditions for non - Beijing households to purchase houses, supporting the housing needs of multi - child families, optimizing personal housing credit policies, and adjusting the project approval method for real - estate development. On January 1, 2026, "Qiushi" proposed that policies should be sufficient at one time to avoid a game between the market and policies [3][7]. - **Cyclical Products**: For the cement and glass industries, with demand declining, the effective reduction of supply is crucial. Currently, the average profitability of the cement and float glass industries has fallen below the break - even line. The cold - repair reduction of glass production capacity in Q1 will determine the price recovery space of float glass from March to April. The glass fiber sector has relatively good profitability, with stable demand growth and potential for staged price increases [4][8]. - **New Fields**: The high - growth of the AI supply chain in 26H1 is the most certain direction. Special electronic cloth has high demand elasticity and limited short - term supply, so its price is elastic. The increasing semiconductor/storage capital expenditure at home and abroad drives the performance and valuation of the clean - room sector. The theme investment in commercial aerospace is constantly catalyzed [4][8]. 3.2 Profit Forecast and Valuation of Main Covered Companies The report provides the profit forecast, valuation, and investment ratings of 28 companies from 2024 to 2027, including Punaite, China Jushi, and Conch Cement.
