煤炭股走强，煤炭ETF涨近3%，能源ETF涨近2%

Core Viewpoint - The coal sector is experiencing a strong performance, with significant gains in various coal stocks and ETFs, driven by improving supply-demand fundamentals and potential price rebounds in coal types [1][2]. Group 1: Stock Performance - China Coal Energy surged over 7%, while Shaanxi Coal and Yanzhou Coal increased by more than 3%, and China Shenhua and Lu'an Environmental Energy rose over 2% [1]. - The coal ETF rose nearly 3%, and the energy ETF increased by nearly 2% [1]. Group 2: Market Conditions - Current prices for thermal coal and coking coal remain at historical lows, providing room for a rebound [2]. - Supply-side policies aimed at reducing overproduction are expected to constrain output, while demand is anticipated to recover during the peak season of September and October, improving the coal supply-demand fundamentals [2]. - Both thermal coal and coking coal are expected to exhibit upward price elasticity, with thermal coal supported by long-term contract mechanisms and profit-sharing logic between coal and power companies [2]. - Coking coal, being more market-sensitive, may show greater price elasticity due to its higher marketization [2].
