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: 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.
