Structural Characteristics - The July market typically exhibits structural characteristics, with high success rates in sectors like military, new energy, and resource industries such as steel, chemicals, and non-ferrous metals, driven by policy expectations and industry cycles [2].

Investment Opportunities - In July, focus on sectors with earnings forecast discrepancies and recovery potential, including non-US export chains, price increase chains, AI chains, and financial sectors [6]. - The military sector is expected to benefit from policy and event-driven catalysts, particularly during the transition from the 14th to the 15th Five-Year Plan [6]. - The technology sector, especially AI, is anticipated to continue its upward trend due to favorable valuations and market sentiment [6]. - Resource sectors are likely to see improvements due to seasonal demand and price increases in the third quarter [6].
