一买就跌？一卖就涨？散户最头疼的问题，这篇给你讲透！

Core Viewpoint - The article emphasizes the importance of asset allocation as a solution to the challenges faced by investors, advocating for a structured approach to investment through the "Snowball Three-Point Method" which focuses on diversification and long-term strategies [3][6]. Group 1: Investment Challenges - Many investors fall into common traps such as believing they can time the market perfectly, leading to poor decision-making and losses [5]. - Data indicates that most investors fail to outperform the funds themselves, not due to poor fund selection, but because they struggle to hold onto their investments [5]. Group 2: Snowball Three-Point Method - The core principle of the Snowball Three-Point Method is summarized in twelve words: "Do not predict, only respond, diversify investments, and win passively" [8]. - The method includes three types of diversification: asset diversification, market diversification, and time diversification [9]. Group 3: Asset Diversification - Different asset classes (stocks, bonds, commodities) have distinct return characteristics and low correlation, which helps in risk hedging [10]. - Historical correlation analysis from 2003 to 2023 shows that stocks, bonds, and commodities have low correlations, indicating the benefits of diversified asset allocation [11]. Group 4: Market Diversification - Global economic conditions lead to varying asset performance across different markets, which can further smooth out portfolio volatility [12]. - Correlation analysis from 2021 to 2024 shows that different global indices exhibit low to negative correlations, reinforcing the need for market diversification [13]. Group 5: Time Diversification - Regular investment through methods like dollar-cost averaging can mitigate the risks associated with market timing [14]. - Time diversification allows investors to achieve an average market cost over time, reducing the impact of volatility [15]. Group 6: Dynamic Adjustment and Rebalancing - Initial asset allocation should not be static; adjustments should be made based on changing asset performance and market conditions [16]. - Dynamic rebalancing helps maintain the original asset allocation ratios, facilitating a buy-low, sell-high strategy [17][18]. Group 7: Practical Implementation of the Three-Point Method - The implementation involves three steps: risk assessment to customize investment plans, selecting funds from a curated pool, and ongoing dynamic rebalancing [20][22][26]. - The article provides examples of asset allocation strategies for different risk profiles, illustrating how to construct a personalized investment portfolio [21]. Group 8: Half-Position Strategy - The half-position strategy balances market exposure and risk, allowing for flexibility in responding to market fluctuations [29]. - This strategy involves maintaining a balanced allocation between equities and fixed income, which helps manage both risk and opportunity [30]. Group 9: Specific Asset Allocation Recommendations - The recommended allocation includes 50% in fixed income (with a focus on domestic bonds), 45% in equities (with a mix of domestic and international), and 5% in commodities, primarily gold [32][34][35]. - The rationale for these allocations is based on current market conditions, expected returns, and risk considerations [33][36].
