题材轮冒烟，主升逻辑和方向有啥变？

Market Overview - A-shares continue to rebound with all three major indices closing higher; Shanghai Composite Index up 0.76% to 3262.81 points, Shenzhen Component Index up 0.51%, and ChiNext Index up 0.34% [1] - Despite over 4300 stocks rising, trading volume decreased to 1.28 trillion yuan, a 5% drop from the previous day, indicating significant capital divergence [1] Short-term Market Characteristics - Rapid rotation of themes observed, with sectors like Hainan (+5.71%), cross-border e-commerce (9 stocks hitting the daily limit), robotics (catalyzed by Tesla's humanoid robot), and precious metals (new highs in international gold prices) leading the gains [1] - High valuation tech stocks such as semiconductors and consumer electronics experienced pullbacks, suggesting weak sustainability of themes and strong short-term profit-taking intentions [1] - Quality performance stocks are gaining traction as the market shifts towards more certain earnings, particularly in sectors like gold and SOC chips, which have shown high growth in Q1 [1] Mid to Long-term Market Logic - The mid to long-term market logic remains focused on "domestic demand boost + technological breakthroughs + resilient foreign trade" [2] - Domestic consumption is being supported by policies like the upgrade of Hainan's duty-free shopping and the Ministry of Finance's expansion of "zero tariffs," benefiting local enterprises and sectors like cross-border e-commerce and new retail [2] - The semiconductor sector, despite facing tariff disruptions, is still favored by institutions for its advanced processes and self-sufficiency directions, alongside themes like AI computing and robotics [2] - New foreign trade patterns are emerging due to fluctuating U.S. tariff policies, with trends towards regional alliances, RCEP trade facilitation, and a shift towards high-value-added exports [2] Short-term Strategy - Focus on three elastic directions: - Cross-border payment benefiting from the appreciation of the yuan and the decline of the dollar index, with related ETFs and leading stocks expected to see valuation recovery [3] - Export-to-domestic sales, where export chain enterprises with domestic substitution capabilities (e.g., home appliances, light industry) are likely to absorb external shocks through domestic markets [3] - Quality performance lines, with sectors like gold and SOC chips that have pre-increased Q1 earnings and reasonable valuations becoming safe havens for funds [3]
