高点买入亏超50%后，总结出三大血泪教训！

Core Viewpoint - The article reflects on the lessons learned from four years of investment experience, emphasizing that investing requires rational planning and long-term commitment rather than following trends blindly [3]. Group 1: The Cost of Following Trends - The investment in popular funds, particularly in sectors like pharmaceuticals and military, led to significant losses when market conditions changed, revealing the risks of single-sector investments [4][6]. - A specific growth value fund experienced a maximum drawdown of over 50% due to heavy exposure to technology stocks during market downturns [4]. Group 2: Misconceptions About Dollar-Cost Averaging - Increasing investment amounts in a declining market did not yield the expected results, as the account faced multiple interruptions due to insufficient funds, missing opportunities to buy at lower prices [9]. - The failure to adjust investment strategies based on market valuations resulted in continued losses, highlighting the importance of timely decision-making [10][12]. Group 3: Emotional Decision-Making - During a market rally in September 2024, the account still showed a loss of over 40%, leading to a decision to cut losses by redeeming a quarter of the investment, which ultimately missed out on subsequent gains [14][15]. - The experience underscored the need for stop-loss decisions to be based on fundamentals rather than emotions, and the importance of investing with disposable income [16]. Group 4: Key Lessons and Insights - Diversification is crucial to survival, as over-concentration in high-volatility sectors can lead to significant setbacks during corrections; a balanced approach with value funds or fixed-income products is recommended [18]. - A long-term perspective and disciplined execution are essential, with stable investment amounts and dynamic valuation thresholds for profit-taking [20][21]. - Independent thinking is more valuable than following trends, as short-term performance may not reflect long-term stability; index funds are suggested for long-term investments over active funds [22]. Group 5: Rebuilding Investment Confidence - The company is now reallocating previously liquidated funds into diversified indices like CSI 300, CSI 500, and major U.S. indices, adhering to a "five-year hold + annual review" strategy to achieve recovery through low-cost averaging [24]. - The narrative concludes with a belief that respecting market dynamics and maintaining a disciplined approach are key to preserving capital and achieving long-term success [25][26].
