Quantitative Models and Construction Methods Model Name: Quantitative Market Trend Analysis Framework - **Model Construction Idea**: The model aims to solve the systematic rotation problem of styles by conducting a bottom-up quantitative market trend analysis. It identifies the dominant asset characteristics that represent the future market's mainstream style through a comprehensive comparison of assets[1][5] - **Model Construction Process**: - The model considers five style stages based on the asset's industry lifecycle: external growth, quality growth, quality dividend, value dividend, and bankruptcy value[1][5] - The priority for asset comparison is based on the sequence: growth (g) > return on equity (ROE) > dividend (D)[1][5] - The model uses the spread of asset advantage differences to capture the trend changes of top assets, similar to factor timing[20] - **Model Evaluation**: The framework has shown good explanatory power for past A-share style rotations, achieving an annualized return of 27.25% since 2009[15] Model Backtesting Results - **Quantitative Market Trend Analysis Framework**: -
