Core Viewpoint - The article discusses the investment opportunities and strategies based on different star ratings of the market, specifically focusing on the current 3.x star rating and the appropriate investment combinations for both existing and new funds [1][11][67]. Group 1: Star Rating and Investment Strategies - The "螺丝钉星级" (Screw Star Rating) is used to assess the overall market valuation, with a scale from 1 to 5 stars indicating different investment phases [6][9]. - A 5-5.9 star rating represents the best phase for investing in stock funds, characterized by a high number of undervalued options and limited downside risk [26][28]. - In the 4-4.9 star range, there are still some undervalued options, but the number decreases, and investment amounts should be reduced compared to the 5-star phase [31][32]. - The 3-3.9 star range indicates that most options are either fairly valued or overvalued, making it less favorable for new investments in stock funds [35][39]. Group 2: Current Market Valuation - As of early January 2026, the market is around 3.9 stars, with most options returning to normal valuations and few remaining undervalued [11][67]. - The article notes that during the extreme valuation of 5.9 stars in September 2024, a significant portion of the market was undervalued [12]. - Historical data shows that at 3.7 stars in early 2021, there were no undervalued options available, highlighting the cyclical nature of market valuations [13][36]. Group 3: Investment Combinations - The article outlines various investment combinations suitable for different star ratings, including "主动优选" (Active Selection), "指数增强" (Index Enhancement), and "月薪宝" (Monthly Salary Treasure) [19][30][55]. - The "月薪宝" combination, which includes a higher proportion of stock assets, is currently undervalued, while "主动优选" and "指数增强" have returned to normal valuations [20][21]. - For 4-star phases, a more conservative approach with lower stock exposure, such as the "月薪宝" combination, is recommended to mitigate volatility [33][34]. Group 4: Asset Allocation Strategies - The article suggests using a "100-age" rule for allocating existing funds, where the percentage of stock assets should be based on the investor's age [49][46]. - For new funds, a systematic investment approach (定投) is recommended, particularly during favorable market conditions [51][29]. - The article emphasizes the importance of diversifying investments across different asset types to manage risk effectively [34][57].
