Core Insights - The report from Founder Securities indicates that after a continuous rise in stock prices, the valuation levels of small and micro-cap stocks have significantly increased, yet both absolute and relative valuation levels remain considerably below historical extremes [1][3] Valuation Analysis - Small-cap companies are expected to yield significant excess returns by 2025, with the CSI 2000 index showing a year-to-date increase of 25.3%, outperforming other major indices [2] - The Wande Micro-cap Index has surged over 50%, reaching historical highs, while the overall P/E ratio of the CSI 2000 index is currently at 146 times, and the P/B ratio is 2.75, both being the highest since the index was launched in 2023 [2] - The overall valuation of small-cap stocks is heavily influenced by a few loss-making companies, with the CSI 2000 index reporting a total net profit of 77.5 billion, contrasted by losses totaling 121.1 billion from loss-making firms [2] Relative Valuation Comparison - A comparison of the smallest 20% of A-share companies against the largest 20% shows a median P/E ratio of 1.17 times and a median P/B ratio of 1.09 times, indicating that relative valuation levels are consistent with those of the CSI 2000 constituents and even lower [3] - Despite the increase in stock prices, the valuation levels of small and micro-cap stocks have risen but still have a significant distance to historical peaks, suggesting that the small-cap style may reflect the innovative exploration characteristics during the economic transformation and upgrading period [3]

Summary of Key Points from Conference Call Industry or Company Involved - The discussion revolves around the relationship between the equity market, specifically the 中证 500 Index, and the bond market, particularly the 10-year government bond yield. Core Insights and Arguments - There exists a "seesaw effect" between the stock market and the bond market, where the 中证 500 Index and the 10-year government bond yield are positively correlated. Specifically, for every 100-point increase in the 中证 500 Index, the 10-year bond yield rises by approximately 0.9 basis points [1][2][5]. - The Bernanke three-factor model effectively decomposes the yield of the 10-year government bond, achieving an R-squared value of 0.85 when fitted to data since 2016. This model uses the 7-day reverse repo rate as a proxy for short-term rates, current CPI for inflation expectations, and the difference between social financing and M2 to represent economic conditions [1][4][7]. - The relationship between the 中证 500 Index and the 10-year bond yield shows a leading effect, indicating that an increase in the stock index can lead to a rise in bond yields in the following month [2][11]. - The bond market has already absorbed the impact of the recent rise in the equity market, with an increase of about 4-5 basis points in the bond yield since mid-June [14]. - If the equity market rises by an additional 5%, it could exert an extra pressure of about 3 basis points on the bond market, pushing yields to a range of 1.70% to 1.75%. A further 10% increase in the equity market could raise yields by approximately 6 basis points, resulting in a range of 1.75% to 1.80% [2][14]. Other Important but Possibly Overlooked Content - Different equity indices have varying degrees of influence on the 10-year bond yield. The 中证 1,000 and 中证 2000 indices show weaker correlation with the bond market compared to larger indices like the 上证综指 and 深证成指 [8][9]. - The structural integrity of the model is affected by the inclusion of large-cap indices, which can disrupt the original model's structure, particularly the impact of social financing minus M2 [9]. - The current market environment has led to a notable increase in the correlation between the 中证 500 Index and the 10-year bond yield, a phenomenon not seen in the past decade. This is attributed to stable fundamental and monetary conditions [15].

Group 1 - The A-share market has experienced a strong rebound since September 24, 2023, driven by significant policy measures, with core broad indices recording over 20% gains, while the CSI 2000 index, which covers small and micro-cap companies, has surged over 64% [1][2][68] - The CSI 2000 index is characterized by low market capitalization and high elasticity, making it a key driver of the current market rally [1][2][68] - The People's Bank of China has implemented a moderately loose monetary policy, with M2 balance growing by 8.3% year-on-year as of June 2025, indicating continued liquidity support [1][3][68] Group 2 - The number of specialized and innovative enterprises within the CSI 2000 index has reached 521, accounting for 26.05%, primarily benefiting from targeted fiscal support and technological advancements [1][5][68] - The focus on specialized and innovative policies has been instrumental in promoting small and micro enterprises, aligning with the direction of "new quality productivity" [5][7][68] Group 3 - Institutional investors have shown increased interest in small-cap stocks, with the market capitalization of actively managed funds in the CSI 2000 index rising significantly since Q4 2024 [8][10][69] - The trading volume of the CSI 2000 index has increased from less than 10% in 2021 to nearly 30% of the total market trading volume, reflecting heightened investor activity [10][12][69] Group 4 - The CSI 2000 index, launched on August 11, 2023, selects 2000 securities with smaller market capitalizations and good liquidity, focusing on emerging industries [14][70] - As of July 18, 2025, the average market capitalization of the CSI 2000 index components is 5.355 billion, significantly lower than other indices like CSI 1000 and CSI 500 [17][70] Group 5 - The CSI 2000 index has shown superior long-term performance compared to other broad indices, with an annualized return of 9.29% since its inception [39][70] - The index's high growth potential is expected to offset its high valuation, with a price-to-earnings ratio of 138.35 as of July 18, 2025 [22][70] Group 6 - The Huaxia CSI 2000 ETF, launched on September 6, 2023, aims to track the CSI 2000 index and has achieved a cumulative excess return of 30.46% since its inception [43][71] - The ETF's excess returns are primarily attributed to stock selection, demonstrating effective management and strategy [55][71]

Quantitative Models and Factor Analysis Quantitative Models and Construction - **Model Name**: Brinson Attribution Model **Model Construction Idea**: The model is used to decompose the excess return of a portfolio relative to its benchmark into contributions from sector allocation and stock selection [59] **Model Construction Process**: The Brinson model decomposes the excess return ($R_p - R_b$) into two components: $$ R_p - R_b = \sum_{i=1}^{N} (w_{pi} - w_{bi})R_{bi} + \sum_{i=1}^{N} w_{pi}(R_{pi} - R_{bi}) $$ - $w_{pi}$: Portfolio weight in sector $i$ - $w_{bi}$: Benchmark weight in sector $i$ - $R_{pi}$: Portfolio return in sector $i$ - $R_{bi}$: Benchmark return in sector $i$ The first term represents the sector allocation effect, and the second term represents the stock selection effect [59] **Model Evaluation**: The model effectively identifies the primary source of excess returns, highlighting the significant contribution of stock selection in the analyzed ETF [59] Quantitative Factors and Construction - **Factor Name**: Sampling Replication Factor **Factor Construction Idea**: This factor aims to balance tracking error and liquidity by selecting representative stocks from the index components [51][54] **Factor Construction Process**: - **Layered Sampling Method**: - Divide stocks into groups based on characteristics such as market capitalization and valuation - Select representative stocks from each group to form the portfolio [51] - **Optimization Sampling Method**: - Minimize tracking error by controlling the portfolio's risk exposure to match the benchmark index - Use optimization techniques to ensure the portfolio aligns with the index's style factors (e.g., size, valuation, momentum) [54] **Factor Evaluation**: The factor ensures efficient tracking of the benchmark index while maintaining liquidity, making it suitable for indices with a large number of components [51][54] Backtesting Results of Models and Factors - **Brinson Attribution Model**: - Excess Return Attribution (2023-12-31): Total Excess Return: 3.09%, Sector Allocation: -0.04%, Stock Selection: 3.13% [60] - Excess Return Attribution (2024-06-30): Total Excess Return: 0.50%, Sector Allocation: -0.15%, Stock Selection: 0.65% [60] - Excess Return Attribution (2024-12-31): Total Excess Return: 3.10%, Sector Allocation: 0.10%, Stock Selection: 3.00% [60] - **Sampling Replication Factor**: - Tracking Error Metrics: - Average Deviation from Benchmark: 0.16%-0.44% - Maximum Deviation from Benchmark: 0.43%-1.35% [60] - Stock Coverage: - Number of Holdings (2023 Year-End): 824 stocks (812 from the index) - Number of Holdings (2024 Mid-Year): 844 stocks (837 from the index) - Number of Holdings (2024 Year-End): 914 stocks (901 from the index) [54] - **ETF Performance Metrics**: - Annualized Excess Return: 15.14% - Annualized Information Ratio (IR): 3.14 [56][58] - Cumulative Excess Return Since Inception: 30.46% [56] - IPO Allocation Returns: 2024: 1.80%, 2025 H1: 0.99% [62]

Summary of Conference Call Records Industry or Company Involved - The discussion revolves around the investment strategies and market dynamics in the context of style rotation, particularly focusing on large-cap vs small-cap and growth vs value styles in the Chinese stock market. Core Points and Arguments 1. **Style Rotation Framework**: The construction of a style rotation framework requires selecting appropriate indices to describe large-cap, small-cap, and growth vs value styles, considering macroeconomic cycles, market structure, and economic background that drive risk preference shifts [1][3][4] 2. **Historical Examples of Style Rotation**: Historical cases show a correlation between economic cycles and style rotation, such as the bull market in the ChiNext from 2013 to 2015 and the supply-side reforms in 2017, indicating that different styles perform well in different economic conditions [5] 3. **Current Index Usage**: The commonly used indices include the CSI 300 for large caps and the CSI 500 for small caps, but the CSI 1000 is increasingly viewed as a mid-cap index, suggesting a need for smaller indices like the CSI 2000 to represent small caps [7] 4. **Barbell Strategy**: Recent trends in the domestic market show a barbell strategy where small caps and value (dividend) stocks are performing well, reflecting a narrowing investment focus among investors [8] 5. **Long-term Style Judgement**: Long-term core style judgement relies on macro and meso indicators, while short-term factors include capital flow, sentiment, and institutional behavior, which can be analyzed quantitatively [9] 6. **Challenges in Style Index Construction**: The construction of style indices faces challenges such as overfitting due to excessive filtering conditions, which can compromise the purity of the style representation [10][11] 7. **Stability of Market Capitalization Distribution**: Maintaining a stable market capitalization distribution is crucial for effective backtesting over long periods, avoiding frequent adjustments to the benchmarks used for small-cap representation [13] Other Important but Possibly Overlooked Content 1. **Quantitative Analysis of Style Rotation**: Quantitative analysis can validate subjective perceptions of style rotation through multi-dimensional backtesting, utilizing factors from risk models like Barra [6] 2. **Growth Factor Selection**: Growth factors are selected based on pure metrics such as revenue growth and net profit growth, categorized into groups to better represent extreme growth styles during bullish phases [14] 3. **Value Index Characteristics**: The value index is constructed using simple metrics like P/E and P/B ratios, focusing on accurately reflecting undervalued stocks without additional factors that could distort its representation [15] 4. **Future Reporting Plans**: The company plans to provide detailed reports on specific strategies to investors and leadership in the coming days, indicating ongoing engagement and communication with stakeholders [16]

Core Viewpoint - The article discusses the effectiveness and risks associated with the "micro-cap stock strategy," highlighting its significant returns while also addressing the inherent volatility and potential for substantial losses [2][40]. Group 1: Micro-Cap Stock Strategy Effectiveness - The micro-cap stock strategy has shown long-term effectiveness, with the Wind Micro-Cap Stock Index achieving a remarkable 51.43% increase in 2025, contrasting with a mere 15.39% rise in bank stocks [2][40]. - The Wind Micro-Cap Stock Index is composed of the smallest 400 stocks from the A-share market, excluding certain categories, and is rebalanced monthly, which allows for high-frequency trading that capitalizes on market volatility [4][11]. - The strategy's success is attributed to its ability to generate excess returns through high-frequency trading rather than relying on fundamental company performance [12][19]. Group 2: Impact of Major Shareholder Actions - Major shareholder sell-offs have limited impact on micro-cap stocks due to regulatory constraints, making the perceived risks of such actions largely unfounded [14][40]. - The article emphasizes that the micro-cap stock strategy's returns are primarily driven by the index's trading rules rather than the underlying fundamentals of the companies involved [39][40]. Group 3: Risks and Considerations - The micro-cap stock strategy carries significant tail risks, with historical data showing potential declines of 40%-50% during market downturns, which investors must be prepared to endure [40][41]. - The article warns that while the micro-cap index can yield high returns, it is essential to recognize the associated risks and not to concentrate investments solely in this strategy [41][42]. - Diversification is recommended to mitigate risks, suggesting that investors should not allocate all resources to micro-cap stocks but rather create a balanced portfolio [42][43].

Group 1 - The small-cap stocks are showing an upward trend, with the China Securities 2000 Enhanced ETF (159552) increasing by 0.69% as of 10:11 AM on July 14, and it has gained 34.00% year-to-date and over 70% in the past year, marking its 24th new high of the year [1] - The fund has seen a continuous net inflow of capital for 10 days as of July 11, with a year-to-date growth in scale of 1071.33% [1] - According to China International Capital Corporation (CICC), despite the recent rise in small-cap stock valuations and potential short-term volatility, the trend of small-cap outperforming large-cap may not be over, indicating a favorable environment for small-cap style investments [1] Group 2 - The China Securities 2000 Enhanced ETF (159552) tracks the China Securities 2000 Index, which reflects the price performance of a group of small-cap stocks in the A-share market, aiming to achieve excess alpha while capturing the index beta [1] - The ETF offers higher capital utilization compared to off-market index enhancement funds, and its secondary market trading incurs lower costs than off-market subscription and redemption fees for general index enhancement funds, making it an effective investment tool for index enhancement strategies [1] - For investors without a brokerage account, the off-market fund options, such as the China Securities 2000 Index Enhancement (A: 019918 C: 019919), are recommended for investment [1]

Core Viewpoint - The introduction of the CSI 2000 Index reflects the increasing representation of small and medium-sized companies in the A-share market, showcasing strong long-term performance with a cumulative return of 166.50% since its base date, outperforming major broad-based indices [2][3]. Group 1: Characteristics of the CSI 2000 Index - The CSI 2000 Index uniquely focuses on small and micro-cap stocks, comprising 2000 stocks with smaller market capitalizations and better liquidity, effectively complementing other indices like CSI 300 and CSI 500 [7]. - The index covers 30 primary industries, with high-growth sectors such as machinery, electronics, basic chemicals, and pharmaceuticals accounting for nearly 40% of its composition, indicating a diversified and growth-oriented portfolio [9]. - The index exhibits high elasticity and volatility, making it attractive to investors with a higher risk appetite, especially in a macro environment characterized by loose liquidity [11]. Group 2: Investment Strategies and Opportunities - The CSI 2000 Index is well-suited for quantitative strategies due to its lower analyst coverage, allowing for the identification of undervalued stocks and pricing inefficiencies, which can lead to excess returns [19]. - The high trading activity and turnover rates of the CSI 2000 Index enhance the effectiveness of quantitative trading strategies, enabling better monitoring of market dynamics and execution of trades [18]. - The index's broad selection of constituent stocks provides greater freedom in stock selection, allowing for the application of various alpha factors and reducing exposure risks associated with non-index stocks [17].
