Report Industry Investment Rating - The investment rating for the coal mining industry is "Bullish" [2] Report's Core View - The coal industry is at the beginning of a new upward cycle, with fundamental and policy factors in resonance. It is advisable to allocate coal stocks on dips. The underlying investment logic of coal production capacity shortage remains unchanged, and coal prices have established a bottom and are expected to rise. High - quality coal enterprises have core asset attributes such as high profitability, high cash flow, high ROE, and high dividends. The coal sector is still undervalued, and its valuation is expected to increase. The coal supply bottleneck is expected to last until the "15th Five - Year Plan", and coal prices are likely to remain high. The report continues to be bullish on the coal sector and recommends top - down attention to several types of coal companies [3][11][12] Summary by Directory 1.
