做好三件事，投资其实不难！

Core Viewpoint - Investment success hinges on three key factors: buying price, portfolio structure, and patience [4][5]. Group 1: Buying Price - It is crucial to avoid purchasing assets at inflated prices; even a good company can lead to poor returns if bought at a high price [6][7]. - Valuation metrics, such as the price-to-earnings (P/E) ratio, serve as a straightforward measure to assess whether an asset is overvalued or undervalued [8][10]. - Historical comparisons of valuation can provide context; for instance, the average P/E ratio of the CSI 300 index over the past decade is approximately 12 times, and deviations from this average can signal potential risks or opportunities [10][11]. Group 2: Portfolio Structure - Diversification is essential as it acknowledges the unpredictability of market movements; overconfidence in one's judgment can lead to significant losses [13][14][15]. - Relying solely on one stock or sector increases risk, as market conditions can change unexpectedly, leading to potential capital loss [17][18]. - Embracing broad market indices, such as the CSI 300 or Hang Seng Index, allows investors to capture growth across various sectors, reducing the risk associated with individual stocks [19][20]. Group 3: Patience - The stock market is volatile in the short term but tends to stabilize over the long term; thus, long-term investment strategies are more likely to yield positive returns [21][22]. - Historical data indicates that holding investments for longer periods significantly increases the probability of achieving positive returns, with a 60% chance of profit after one year and over 80% after three years [24]. - Long-term investments should be made with funds that are not needed in the near future, as this reduces anxiety during market fluctuations and helps avoid panic selling [26][27].
