Core Viewpoint - The article discusses the investment strategies for index funds, emphasizing the importance of understanding index rebalancing and its impact on investment performance [6][7][8]. Group 1: Index Rebalancing - Index rebalancing refers to the adjustment of constituent stocks in an index according to specific rules, which can lead to buying high and selling low during market fluctuations [6][7]. - Regular rebalancing can cause indices like the CSI 500 and CSI 1000 to follow a pattern of buying stocks that have risen significantly and selling those that have fallen, potentially exacerbating market volatility [7][8]. Group 2: Historical Context - The phenomenon of indices chasing performance was observed during the 1990s tech bubble in the U.S., where stocks associated with the internet saw significant price increases, leading to their inclusion in major indices like the Nasdaq 100, which later suffered during the market correction [8]. Group 3: Solutions to Mitigate Risks - Two strategies are proposed to mitigate the risks associated with index rebalancing: 1. Consider strategy indices that do not rely on market capitalization for stock selection, thus avoiding the pitfalls of performance chasing [11][12]. 2. Explore enhanced index funds, which invest 80% in index constituents while using 20% for active management to avoid stocks with clear bubbles [13][14].
