Investment Rating - The industry investment rating is "Positive" and maintained [10] Core Viewpoints - The report emphasizes the potential for coal prices to rebound due to the "anti-involution" policy, which is expected to lead to actual production cuts and improve coal prices. The analysis is based on the mean reversion of return on equity (ROE) and the reasonable profit distribution levels of thermal coal and coking coal within their respective industrial chains [2][6][8] Summary by Sections Introduction - The "anti-involution" policy has catalyzed significant increases in coal commodities and equity prices. The report highlights the importance of understanding the future space for coal under this policy, particularly following the State Energy Administration's notice regarding coal mine production inspections [6][18] ROE Perspective - The report calculates the expected central price levels for thermal coal and coking coal based on historical average ROE. The central price for thermal coal is estimated at 749 CNY/ton, which is 96 CNY/ton higher than the price of 653 CNY/ton on July 25, 2025 (+14.7%). For coking coal, the central price is estimated at 1838 CNY/ton, which is 158 CNY/ton higher than the July 25 price of 1680 CNY/ton (+9.4%) [6][34][35] Industry Chain Perspective - The report assesses the reasonable price levels for thermal coal and coking coal based on profit distribution in the coal-electricity and coal-steel industrial chains. It estimates that the reasonable price for thermal coal could be between 776 CNY/ton and 835 CNY/ton, reflecting potential increases of 18.9% and 27.9% respectively from current prices. For coking coal, the reasonable price could range from 1707 CNY/ton to 2094 CNY/ton, with corresponding increases of 1.6% to 24.7% [7][44][45] Investment Recommendations - The report suggests that there is still room for price-to-book (PB) mean reversion, indicating a favorable investment ratio for coal stocks. It recommends focusing on short-term rebounds and long-term reversal opportunities in the coal sector. Specific stock recommendations include: 1. Elastic stocks: Lu'an Environmental Energy, Pingmei Shenma, Huaibei Mining, Shanxi Coking Coal, Yanzhou Coal, Jinkong Coal, and Shanmei International 2. Long-term stable profit leaders: China Coal Energy (A+H), China Shenhua (A+H), and Shaanxi Coal and Chemical 3. Transition growth stocks: Electric Power Investment Energy and New Energy [8][50][52]
