Core Viewpoint - The article discusses the historical performance and current valuation of the China Securities Value Index, its suitability for investment, and available index funds for investors [1]. Group 1: Index Types - A-shares indices are categorized into four main types: broad-based indices, strategy indices, industry indices, and thematic indices [5][6][7][8][9]. - Strategy indices are built on broad-based indices and utilize specific investment strategies, catering to diverse investor needs [7]. - Industry indices focus on stocks within specific sectors, while thematic indices relate to specific themes like technology and renewable energy [8][9]. Group 2: Value Strategy Indices - The article highlights six mainstream strategies within value indices, including low volatility, growth, and quality strategies, with a focus on the value strategy originating from Benjamin Graham [10][12]. - Common value strategy indices include the CSI 300 Value Index, which selects stocks based on low price-to-earnings and price-to-book ratios [11][12]. Group 3: China Securities Value Index - The China Securities Value Index, established on December 8, 2017, selects 100 stocks with low valuations and a historical return on equity (ROE) of at least 12% [15][16][17]. - The index employs an equal-weighting methodology, making it unique among value strategy indices [15]. Group 4: Historical Performance - The China Securities Value Index has outperformed the CSI 300 Index over the long term, with returns of 8.51% compared to the CSI 300's 4.72% from August 2011 to June 2025 [24][25][26]. - The article emphasizes the effectiveness of value investing in the A-share market [25]. Group 5: Valuation Metrics - Historical valuation data indicates that the index's price-to-earnings ratio is generally higher than its price-to-book ratio, suggesting that price-to-book may be a more reliable metric in certain conditions [29][30]. - The article notes that valuation percentiles are just one reference for assessing valuation levels, as value indices consider multiple factors [32]. Group 6: Index Funds - The article mentions that the scale of index funds related to the China Securities Value Index is relatively small, totaling less than 10 billion yuan, which is less than 1% of the A-share stock fund market [38]. - The article also discusses the average price-to-earnings ratios of stocks being added and removed from the index during adjustments [39]. Group 7: Conclusion - The value strategy index, rooted in Graham's principles, has evolved to include quality metrics like ROE to mitigate risks associated with low valuation traps [41]. - The China Securities Value Index has consistently outperformed the CSI 300 Index, reinforcing the long-term viability of value investing in the A-share market [41].

Core Viewpoint - The article emphasizes the importance of percentile as a reference indicator when investing in index funds, suggesting that low percentile investments may present potential opportunities [1][6]. Summary by Sections Percentile Types - There are two types of percentiles: 1. **Time Percentile**: Indicates the current valuation's position within historical valuations over a specific time frame. For example, if the current valuation is lower than 90% of the valuations in the last five years, it is at the 10th percentile [3]. 2. **Space Percentile**: Represents the current valuation's position between the historical minimum and maximum valuations. For instance, if the historical minimum P/E ratio is 10 and the maximum is 50, a current P/E of 20 would place it at the 25th percentile [4]. Practical Investment Considerations - Time percentiles are more commonly used in actual investments, but relying solely on percentiles carries risks [5]. Risks of Relying Solely on Percentiles - **Risk 1**: Short index launch time can lead to low historical valuation reference value. For example, newly established indices may not provide a reliable bottom valuation due to limited historical data [9][10]. - **Risk 2**: Changes in index rules can significantly alter valuation data. For instance, the change in the China Securities 100 index from a market-cap-based selection to a leading strategy can affect historical valuation references [12][13]. - **Risk 3**: Different weighting algorithms for valuations can lead to changes in percentiles. For example, the China Securities Dividend Index's shift from market-cap weighting to dividend yield weighting has resulted in discrepancies in reported P/E ratios [14][18]. - **Risk 4**: Significant fluctuations in earnings can cause P/E percentiles to become misleading. For instance, if a company's earnings surge, the P/E ratio may appear low, creating a "value trap" scenario [20][21]. Conclusion - Investments with low percentiles are worth researching, but low percentiles do not guarantee undervaluation. Factors such as short historical data, changes in index rules, different valuation algorithms, and earnings volatility can lead to percentile failures, necessitating a detailed analysis of each situation [25][26].

Core Viewpoint - The article discusses the characteristics of value strategy indices in the A-share market, highlighting the differences between various indices such as 300 Value, Preferred 300, and China Securities Value, while also addressing the current investment value of these strategies [1][11]. Group 1: Value Strategy Indices - Value strategy indices focus on investing in a basket of low price-to-earnings (P/E) and low price-to-book (P/B) ratio stocks [5][53]. - There are four main types of indices in the A-share market: broad-based indices, strategy indices, industry indices, and thematic indices [6][7][8][9]. - The six mainstream strategies within the strategy indices include quality strategy, leader strategy, dividend strategy, value strategy, low volatility strategy, and growth strategy [10][15]. Group 2: Specific Value Indices - The 300 Value Index, launched on December 31, 2004, selects 100 stocks from the CSI 300 based on low P/E, low P/B, low price-to-cash flow, and high dividend yield [12][19]. - The Preferred 300 Index, established on December 31, 2008, not only selects undervalued stocks but also considers the company's profitability and growth potential [12][24]. - The China Securities Value Index, introduced on June 29, 2007, is unique as it uses equal weighting, meaning each stock has the same proportion, and it focuses on mid and small-cap stocks [13][25]. Group 3: Performance and Historical Data - From August 19, 2011, to May 19, 2025, the 300 Value Index achieved a return of 8.59%, the Preferred 300 Index 9.98%, and the China Securities Value Index 8.45%, all outperforming the CSI 300 Index, which had a return of only 4.61% during the same period [32]. - The historical valuation data shows that the P/E ratios of these indices are generally higher than their P/B ratios, indicating that some companies may have declining earnings, which can lead to inflated P/E ratios [35][36]. Group 4: Selection Rules and Industry Distribution - The selection rules for the 300 Value Index involve calculating four key indicators: dividend yield, P/B ratio, price-to-cash flow ratio, and P/E ratio, and selecting the top 100 stocks based on these value factors [20][19]. - The industry distribution of the 300 Value and Preferred 300 indices is similar, with significant representation from the financial, industrial, and consumer discretionary sectors, while the China Securities Value Index has a more balanced distribution due to its equal weighting [27][29].
