Core Viewpoint - The article discusses the importance of profit-taking strategies in a structurally differentiated market, emphasizing the need for investors to balance between realizing gains and maintaining exposure to potential future profits [4][15]. Summary by Sections 1. Essence of Profit-Taking - The fundamental logic of investing is to buy low and sell high, but many investors struggle due to market uncertainty and psychological factors like loss aversion and disposition effect [6][7]. - Current market conditions show significant structural differentiation, with some sectors like AI and innovative pharmaceuticals performing well, while others like consumer goods and real estate lag behind [8][15]. - Historical examples from 2007 and 2015 illustrate that even in bull markets, significant corrections can occur, highlighting the importance of strategic profit-taking [10][15]. 2. Rational Strategies for Profit-Taking - **Target Profit Method**: Set a target return (e.g., +15%, +20%, +30%) for selling part or all of the position. This method is straightforward but can lead to missed opportunities if targets are set too low or too high [17][20]. - **Drawdown Profit-Taking Method**: Establish a maximum drawdown threshold (e.g., -10%, -15%) to lock in profits when the threshold is reached, balancing risk tolerance and fund type [22][24]. - **Index Valuation Percentile Method**: Use historical valuation percentiles (e.g., PE, PB ratios) to determine when to sell, with high percentiles indicating overvaluation and low percentiles indicating undervaluation [26][27]. 3. After Profit-Taking: Reinvestment Strategies - **Rebalancing**: Adjust the asset allocation back to the original target if stock exposure has increased significantly due to market gains [30]. - **Seeking New Opportunities**: Identify undervalued investment opportunities in the current market environment [31]. - **Building Cash Reserves**: Maintain some profits in cash to capitalize on better investment opportunities in the future [32]. 4. Conclusion on Profit-Taking - The essence of profit-taking is risk management rather than market prediction, with a focus on understanding personal investment logic and risk tolerance [33][35].
