Quantitative Models and Construction Methods 1. Model Name: Barra Style Factors - **Model Construction Idea**: The model aims to capture the performance of various style factors in the equity market, such as momentum, size, and residual volatility[12][27] - **Model Construction Process**: The model calculates the returns of different style factors over a specified period. For example, the momentum factor return is calculated as: $$ \text{Momentum Factor Return} = \frac{\sum (\text{Stock Returns} \times \text{Momentum Scores})}{\sum \text{Momentum Scores}} $$ where the momentum scores are derived from the past performance of stocks[12][27] - **Model Evaluation**: The model effectively captures the performance of different style factors, providing insights into market trends and investor behavior[12][27] 2. Model Name: Excess Return Monitoring Model - **Model Construction Idea**: This model monitors the relative performance of small and mid-cap indices against a large-cap benchmark to capture market style rotation signals[86] - **Model Construction Process**: The model calculates the rolling 20-day excess returns of indices such as CSI 2000, CSI 1000, and CSI 500 relative to the CSI 300. For example: $$ \text{Excess Return} = \text{CSI 1000 Return} - \text{CSI 300 Return} $$ The model then tracks the percentile rank of these excess returns over a three-year period to identify significant deviations[86] - **Model Evaluation**: The model provides a systematic approach to detect market style rotations, aiding in strategic asset allocation decisions[86] Model Backtest Results - **Barra Style Factors**: - **Momentum Factor**: Weekly return 0.61%, monthly return 0.96%, annualized Sharpe ratio 2.20[12][27] - **Size Factor**: Weekly return 0.56%, monthly return 1.71%, annualized Sharpe ratio -1.78[12][27] - **Residual Volatility Factor**: Weekly return -0.48%, monthly return -0.77%, annualized Sharpe ratio -1.65[12][27] - **Excess Return Monitoring Model**: - **CSI 1000 vs. CSI 300**: 20-day rolling return -3.32%, 3-year percentile 17.0%[86] - **CSI 2000 vs. CSI 300**: 20-day rolling return -4.78%, 3-year percentile 15.1%[86] - **CSI 500 vs. CSI 300**: 20-day rolling return 1.21%, 3-year percentile 66.7%[86] Quantitative Factors and Construction Methods 1. Factor Name: Momentum - **Factor Construction Idea**: The momentum factor captures the tendency of stocks that have performed well in the past to continue performing well in the future[12][27] - **Factor Construction Process**: The momentum score for each stock is calculated based on its past returns over a specified period, typically 12 months. The factor return is then computed as: $$ \text{Momentum Factor Return} = \frac{\sum (\text{Stock Returns} \times \text{Momentum Scores})}{\sum \text{Momentum Scores}} $$ where the momentum scores are derived from the past performance of stocks[12][27] - **Factor Evaluation**: The momentum factor has shown consistent positive returns, indicating its effectiveness in capturing market trends[12][27] 2. Factor Name: Size - **Factor Construction Idea**: The size factor captures the performance difference between small-cap and large-cap stocks[12][27] - **Factor Construction Process**: The size score for each stock is calculated based on its market capitalization. The factor return is then computed as: $$ \text{Size Factor Return} = \frac{\sum (\text{Stock Returns} \times \text{Size Scores})}{\sum \text{Size Scores}} $$ where the size scores are derived from the market capitalization of stocks[12][27] - **Factor Evaluation**: The size factor has shown mixed performance, reflecting the varying investor preferences for small-cap versus large-cap stocks over time[12][27] Factor Backtest Results - **Momentum Factor**: Weekly return 0.61%, monthly return 0.96%, annualized Sharpe ratio 2.20[12][27] - **Size Factor**: Weekly return 0.56%, monthly return 1.71%, annualized Sharpe ratio -1.78[12][27] - **Residual Volatility Factor**: Weekly return -0.48%, monthly return -0.77%, annualized Sharpe ratio -1.65[12][27]
