The research report released by CITIC Securities highlights that the current A-share market is witnessing pronounced capital concentration and siphoning effects, with the disparities in returns among individual stocks reaching unprecedented levels. Notably, the correlation coefficient between the returns of leading assets and those in the long tail is nearing the divergence threshold of 0.5. Historical analyses reveal that while extreme peaks in capital concentration do not necessarily dictate the overall market trajectory, such divergences in correlation often signal that the primary themes previously driven by consensus will enter a phase of consolidation. This transition is likely to be accompanied by structural shifts in capital behavior and market sentiment. The market's ability to shift from divergence to convergence in the future hinges on the seamless interplay between macroeconomic fundamental growth and global liquidity dynamics. Until macroeconomic externalities become more transparent, relying solely on industry-specific micro-narratives will fall short of breaking the current deadlock of 'capital concentration.' Instead, it is advisable to embrace a new barbell strategy combining 'AI + Energy and Chemicals' to effectively balance risk mitigation and returns.
