Core Viewpoint - The article highlights a significant shift in the public fund industry from a "scale-oriented" approach to a focus on "investor returns," as evidenced by the recent trend of mini funds limiting purchases during peak performance periods [1][8]. Group 1: Mini Funds and Performance - Many small-scale but high-performing "mini funds" have recently announced purchase limits, reflecting a strategic decision to protect existing investors and maintain performance integrity [1][2]. - For instance, the Southern Core Technology fund, which has achieved a 45% return this year, has limited purchases since November 25, with an asset size of only 65 million yuan [2]. - The trend of limiting purchases is prevalent among funds with outstanding performance but small sizes, such as the Chuangjin Hexin Global Pharmaceutical fund, which has seen over 100% returns this year but has an asset size of approximately 42 million yuan [2]. Group 2: Strategic Capacity and Flexibility - The decision to limit purchases is closely tied to the concept of "strategy capacity," which refers to the maximum fund size that can be managed without compromising performance [7]. - Smaller funds can adapt more flexibly to market changes, allowing for quicker adjustments in positions with lower dilution costs [5]. - For example, the E Fund Global Allocation fund has frequently shifted its holdings across major markets, demonstrating the agility that smaller funds possess [5]. Group 3: Protecting Existing Investors - The trend of "sacrificing scale for performance" is also aimed at protecting the interests of current investors, ensuring that the fund's strategy remains effective [7]. - Fund managers emphasize that exceeding strategy capacity can lead to increased trading costs and reduced liquidity, ultimately harming performance [7]. - The article notes that maintaining a smaller fund size allows managers to concentrate investments in fewer stocks, enhancing performance potential [7]. Group 4: Industry Evolution - The public fund industry is transitioning from a focus on growth to prioritizing high-quality development, emphasizing investor interests and product value [8]. - This shift involves a commitment to building brand reputation and product credibility, with a focus on long-term performance stability over short-term growth [8].
