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.
