Core Viewpoint - The introduction of the CSI 2000 Index reflects the increasing representation of small and medium-sized companies in the A-share market, showcasing strong long-term performance with a cumulative return of 166.50% since its base date, outperforming major broad-based indices [2][3]. Group 1: Characteristics of the CSI 2000 Index - The CSI 2000 Index uniquely focuses on small and micro-cap stocks, comprising 2000 stocks with smaller market capitalizations and better liquidity, effectively complementing other indices like CSI 300 and CSI 500 [7]. - The index covers 30 primary industries, with high-growth sectors such as machinery, electronics, basic chemicals, and pharmaceuticals accounting for nearly 40% of its composition, indicating a diversified and growth-oriented portfolio [9]. - The index exhibits high elasticity and volatility, making it attractive to investors with a higher risk appetite, especially in a macro environment characterized by loose liquidity [11].
