Group 1 - The article emphasizes the classic combination of investment strategies, specifically the pairing of CSI 300 with CSI 500, and suggests adding smaller cap stocks through CSI 1000 and potentially CSI 2000 for further diversification [3][4]. - It discusses the importance of balancing growth and value styles in strategy index investments, categorizing them into growth (leaders, growth, quality) and value (dividend, value, low volatility) groups [4][5]. - The A-share market exhibits a rotation between growth and value styles, with growth dominating from 2019 to 2020, value from 2021 to 2024, and a return to growth expected in 2025 [5]. Group 2 - The article advises selecting investments from undervalued varieties within both growth and value styles to enhance portfolio stability [6]. - It highlights the significant volatility associated with industry and thematic indices, noting that broad indices like CSI 300 typically experience 20%-30% fluctuations annually, while industry indices can see 30%-50% volatility, and some thematic investments have exceeded 50% [7]. - To mitigate risk, it recommends limiting individual industry investments to 15%-20% of the portfolio and diversifying across multiple industries to reduce overall volatility [7].

- Model Name: Short-term Quantitative Timing Model; Model Construction Idea: The model aims to provide short-term market timing signals based on various market indicators; Model Construction Process: The model evaluates four main aspects: fundamentals, valuation, sentiment, and liquidity. Each aspect is assessed using specific indicators such as PMI, loan growth, M1 growth, PE and PB ratios, beta dispersion, trading volume sentiment, volatility, interest rates, exchange rate expectations, and financing amounts. The signals from these indicators are combined to generate an overall market timing signal. For example, the formula for the fundamental signal is based on the PMI and loan growth: $$ \text{Fundamental Signal} = \text{PMI} \times \text{Loan Growth} $$ where PMI represents the manufacturing PMI index and Loan Growth represents the year-on-year growth rate of medium and long-term loans in RMB. Model Evaluation: The model has shown significant improvement over the benchmark in terms of annualized returns and maximum drawdown reduction[19][22][23] - Model Name: Growth-Value Style Rotation Model; Model Construction Idea: The model aims to rotate between growth and value styles based on economic cycles and market conditions; Model Construction Process: The model uses a quantitative economic cycle analysis framework to assess the profitability cycle, interest rate cycle, and credit cycle. For example, the profitability cycle slope is calculated as: $$ \text{Profitability Cycle Slope} = \frac{\text{Current Profitability} - \text{Previous Profitability}}{\text{Time Period}} $$ The model also considers valuation differences (PE and PB ratios) and sentiment differences (turnover and volatility). The signals from these indicators are combined to generate a style rotation recommendation. Model Evaluation: The model has shown significant improvement over the benchmark in terms of annualized returns and maximum drawdown reduction[31][32][33] - Model Name: Small-Cap vs. Large-Cap Style Rotation Model; Model Construction Idea: The model aims to rotate between small-cap and large-cap styles based on economic cycles and market conditions; Model Construction Process: Similar to the Growth-Value Style Rotation Model, this model uses a quantitative economic cycle analysis framework to assess the profitability cycle, interest rate cycle, and credit cycle. It also considers valuation differences (PE and PB ratios) and sentiment differences (turnover and volatility). The signals from these indicators are combined to generate a style rotation recommendation. Model Evaluation: The model has shown significant improvement over the benchmark in terms of annualized returns and maximum drawdown reduction[35][36][37] - Model Name: Four-Style Rotation Model; Model Construction Idea: The model combines the Growth-Value and Small-Cap vs. Large-Cap Style Rotation Models to provide a comprehensive style rotation strategy; Model Construction Process: The model integrates the signals from the Growth-Value and Small-Cap vs. Large-Cap Style Rotation Models to recommend allocations across four styles: small-cap growth, small-cap value, large-cap growth, and large-cap value. The recommended allocation is based on the combined signals from the underlying models. Model Evaluation: The model has shown significant improvement over the benchmark in terms of annualized returns and maximum drawdown reduction[39][40][41] Model Backtest Results - Short-term Quantitative Timing Model: Annualized Return 16.27%, Annualized Volatility 14.73%, Maximum Drawdown 27.70%, Sharpe Ratio 0.9620, IR 0.5875[22][27] - Growth-Value Style Rotation Model: Annualized Return 11.35%, Annualized Volatility 20.89%, Maximum Drawdown 43.07%, Sharpe Ratio 0.5239, IR 0.2634[32][34] - Small-Cap vs. Large-Cap Style Rotation Model: Annualized Return 11.99%, Annualized Volatility 22.79%, Maximum Drawdown 50.65%, Sharpe Ratio 0.5241, IR 0.2367[36][38] - Four-Style Rotation Model: Annualized Return 12.90%, Annualized Volatility 21.64%, Maximum Drawdown 47.91%, Sharpe Ratio 0.5776, IR 0.2693[40][41]

Group 1 - The report attempts to integrate subjective judgment and quantitative analysis to construct a style rotation framework, primarily based on five dimensions to build a core style rotation model, which will eventually be applied to actual investable portfolios [3][8] - The fundamental perspective of growth and value style rotation strategy has shown long-term excess returns compared to its balanced allocation benchmark, although the performance of the strategy is limited due to varying transmission paths and delays of different fundamental indicators under different contexts [3][10] Group 2 - The report reviews the construction of style indices and the style rotation framework, continuing to explore the growth and value style rotation from a fundamental perspective [8][17] - Common fundamental indicators are primarily micro data, but the report adopts a different perspective by observing the overall situation of the equity market or specific styles, reflecting the specific conditions of certain groups [8][30] Group 3 - The analysis of fundamental factors is conducted from five angles: growth, profitability, financial health and solvency, operational efficiency, and valuation levels, with growth, profitability, and valuation signals being relatively stable and accurate [9][31] - The overall turnover rate of the growth and value style rotation strategy is low, generally favoring long-term holdings of growth or value stocks, with an average monthly win rate of approximately 60.91% and an average annualized return of about 15.26% from January 1, 2005, to April 29, 2025 [10][31] Group 4 - The growth style index and value style index are constructed based on similar logic, with the main difference being the sorting of constituent stocks using growth and value factors respectively [18][21] - The report outlines the style rotation framework, which is expected to be based on five major dimensions to construct the core style rotation model, focusing on the fundamental dimension of growth and value style rotation [27][30] Group 5 - The report categorizes fundamental indicators into two main types: market overall indicators and style difference indicators, further divided into growth indicators, profitability indicators, financial health and solvency indicators, operational efficiency indicators, and valuation indicators [30][31] - The financial health and solvency indicators focus on the reasonableness of capital structure and short-term liquidity, with asset-liability ratio and current ratio being particularly effective in the context of growth and value style rotation [57][65]
