Core Viewpoint - The "Screw Nut Star Rating" is a tool to assess the overall market valuation, with different star ratings indicating varying investment strategies and methods [4][64]. Group 1: Star Rating System - The star rating system ranges from 1 to 5.9 stars, with each level indicating specific market conditions and investment opportunities [6][64]. - 5-5.9 stars represent the best phase for stock and fund investments, characterized by a high number of undervalued options and limited downside risk [10][12][14]. - 4-4.9 stars indicate a phase where some undervalued options remain, but there is a potential for significant market downturns, with historical declines of 30%-40% possible [22][25][28]. - 3-3.9 stars show a scarcity of undervalued options, suggesting a focus on profit-taking as most assets are at normal or high valuations [48][51]. Group 2: Investment Strategies - In the 5-5.9 star phase, the recommended investment strategy includes actively selecting and enhancing index advisory combinations, as this is when stock and fund investments are most valuable [18][19]. - During the 4-4.9 star phase, investors should control volatility risks and consider methods such as dollar-cost averaging and diversified asset allocation to mitigate potential losses [30][36][42]. - In the 3-3.9 star phase, it is advisable to consider profit-taking opportunities, as most assets are either at normal or high valuations, and to explore other asset classes for potential investments [52][57]. Group 3: Market Conditions and Historical Context - The 5-5.9 star phase is often marked by investor pessimism, despite being the most opportune time for investment [14][15]. - Historical data shows that significant market rebounds typically occur after reaching the 5-star level, indicating a strong potential for future gains [12]. - The 1-star rating represents a bubble phase, with extreme valuations rarely seen, and significant market corrections often follow such peaks [60][61].

Group 1 - The core viewpoint emphasizes the importance of evaluating fund managers' investment styles by referencing the valuation of style indices, such as large-cap value and growth indices, which often overlap with the holdings of active fund managers [2] - In the context of industry indices, if a fund manager heavily invests in specific sectors, the corresponding industry valuations can serve as a reference point for evaluation [3] - Key industries identified include consumer, pharmaceutical, and technology sectors, which were noted to be undervalued as of July 2025, indicating that active funds in these areas were also undervalued [4] Group 2 - The "Screw Nut Star Rating" indicator is utilized to assess the overall market valuation and is suitable for evaluating active fund valuations, with a rating of 4 to 5 stars indicating a favorable investment stage [5] - Once the rating falls below 4 stars, it is generally advised to cease further investments, while maintaining patience with existing holdings [5] - At a rating of 3 stars or above, it is advisable to consider selling for profit-taking [6]
