Quantitative Models and Construction Methods 1. Model Name: Quantitative Market Trend Judgment Framework - **Model Construction Idea**: The model aims to address the systematic rotation of market styles by identifying the dominant asset characteristics that represent the future mainstream market style. It evaluates assets based on the priority of "g > ROE > D" to determine whether there are good assets and whether they are overvalued[5][8][12] - **Model Construction Process**: 1. Define five style stages based on the industry lifecycle: external growth, quality growth, quality dividend, value dividend, and bankruptcy value[8] 2. Use the "g > ROE > D" priority to compare assets, focusing on growth (g), profitability (ROE), and dividend yield (D)[5][8] 3. Incorporate factors such as expected growth (gf), actual growth (g), profitability (ROE), and valuation metrics (PB, DP, BP) to classify and evaluate assets[9][12] 4. Apply the framework to select industries and allocate them equally within each strategy[19] - **Model Evaluation**: The framework has demonstrated strong explanatory power for A-share market style rotation since 2009, achieving an annualized return of 27.06%[19] --- Model Backtesting Results Quantitative Market Trend Judgment Framework - **Annualized Return**: 27.06% since 2009[19] - **Excess Returns by Year**: - 2017: 27% - 2020: 44% - 2022: 62% - 2024: 52% - 2025 (YTD): 8%[22] --- Quantitative Factors and Construction Methods 1. Factor Name: Expected Growth (gf) - **Factor Construction Idea**: Measures the expected growth rate of industries based on analysts' forecasts, regardless of the lifecycle stage[9] - **Factor Construction Process**: 1. Calculate the expected growth rate (gf) for each industry 2. Rank industries based on the highest expected growth rates 3. Select top-performing industries for allocation[9][38] - **Factor Evaluation**: The factor has shown significant excess returns since 2019, with notable performance in 2014-2015 and 2025[38] 2. Factor Name: Actual Growth (g) - **Factor Construction Idea**: Focuses on industries with the highest earnings momentum (△g), particularly during transition and growth phases[9] - **Factor Construction Process**: 1. Use △g to represent earnings momentum 2. Rank industries based on △g and select the top-performing ones 3. Incorporate additional factors such as SUE, SUR, and JOR for refinement[40] - **Factor Evaluation**: The factor has consistently delivered significant excess returns, especially in growth-dominant environments[40] 3. Factor Name: Profitability (ROE) - **Factor Construction Idea**: Targets industries with high ROE and low valuation under the PB-ROE framework, focusing on mature stages[9] - **Factor Construction Process**: 1. Calculate PB-ROE residuals for each industry 2. Rank industries based on residuals and select the top-performing ones[43] - **Factor Evaluation**: The factor performed strongly from 2016 to 2020 but has weakened since 2021[43] 4. Factor Name: Quality Dividend (DP + ROE) - **Factor Construction Idea**: Combines dividend yield (DP) and ROE to identify industries with the highest scores, focusing on mature stages[9] - **Factor Construction Process**: 1. Calculate DP and ROE for each industry 2. Combine the two metrics into a composite score 3. Rank industries and select the top-performing ones[46] - **Factor Evaluation**: The factor has shown significant excess returns in 2016, 2017, and 2023[46] 5. Factor Name: Value Dividend (DP + BP) - **Factor Construction Idea**: Combines dividend yield (DP) and book-to-price ratio (BP) to identify undervalued industries, focusing on mature stages[9] - **Factor Construction Process**: 1. Calculate DP and BP for each industry 2. Combine the two metrics into a composite score 3. Rank industries and select the top-performing ones[49] - **Factor Evaluation**: The factor has delivered significant excess returns in 2009, 2017, and 2021-2023[49] 6. Factor Name: Bankruptcy Value (PB + SIZE) - **Factor Construction Idea**: Targets industries with the lowest PB and SIZE scores, focusing on stagnation and recession stages[9] - **Factor Construction Process**: 1. Calculate PB and SIZE for each industry 2. Combine the two metrics into a composite score 3. Rank industries and select the lowest-scoring ones[52] - **Factor Evaluation**: The factor has shown significant excess returns in 2015-2016 and 2021-2023[52] --- Factor Backtesting Results Expected Growth (gf) - **Recent Performance**: - Lithium: +51.15% (3 months) - Frozen Food: +14.08% (3 months)[38] Actual Growth (g) - **Recent Performance**: - Lithium Chemicals: +51.88% (3 months) - Other Home Appliances: +14.93% (3 months)[41] Profitability (ROE) - **Recent Performance**: - Network Equipment: +12.18% (3 months) - Buses: +10.46% (3 months)[43] Quality Dividend (DP + ROE) - **Recent Performance**: - Timber Processing: +145.24% (3 months) - Lithium Equipment: +21.95% (3 months)[46] Value Dividend (DP + BP) - **Recent Performance**: - Network Equipment: +12.18% (3 months) - Security: -2.24% (3 months)[49] Bankruptcy Value (PB + SIZE) - **Recent Performance**: - Gas: +15.88% (3 months) - Building Renovation: +16.42% (3 months)[52]
