足够分散的组合，还有必要定投吗？

Core Viewpoint - The article discusses the relevance of "Dollar-Cost Averaging" (DCA) in investment strategies, particularly in the context of the "Xueqiu Three-Part Method" which emphasizes asset, market, and timing diversification [6][30]. Group 1: Investment Strategies - The "Xueqiu Three-Part Method" includes asset diversification (stocks, bonds, commodities), market diversification (A-shares, Hong Kong stocks, US stocks), and timing diversification (DCA) [6]. - The author has implemented a weekly DCA strategy and has made seven investments so far [7]. - The decision to set up DCA is more related to the investor's financial situation and risk tolerance rather than the characteristics of the investment itself [8]. Group 2: Perspectives on DCA - Different investors have varying opinions on whether high-volatility products are better suited for DCA or for swing trading [9][10]. - Some believe that stable products should be invested in through DCA, while others argue for lump-sum investments due to their long-term upward trends [11]. - The article emphasizes that the same investment can be approached differently based on individual investor perspectives [13]. Group 3: Dynamic Rebalancing - The concept of "Dynamic Rebalancing" is introduced as a method to maintain the desired asset allocation over time, which is distinct from DCA [18]. - Dynamic rebalancing addresses the risk management aspect of the "Xueqiu Three-Part Method" by adjusting the asset mix back to the original allocation [19]. - The author posits that DCA primarily addresses psychological aspects of investing, helping investors manage their emotions during market fluctuations [20][29]. Group 4: Conclusion - There are no strict rules mandating the use of DCA; investors can choose to invest in a lump sum or in multiple smaller amounts [28]. - DCA and dynamic rebalancing can coexist, allowing for gradual investment followed by rebalancing after a set period [28]. - Ultimately, DCA is viewed as a tool for managing investor psychology rather than a method for maximizing returns [29].
