Quantitative Models and Construction Methods - Model Name: CSI 300 Enhanced Portfolio Model Construction Idea: The model aims to enhance the performance of the CSI 300 Index by leveraging quantitative strategies to generate excess returns over the benchmark[4][8][14] Model Construction Process: The portfolio is constructed by selecting stocks from the CSI 300 Index based on quantitative factors and optimization techniques. The model seeks to maximize excess returns while controlling tracking error relative to the benchmark[8][14] Model Evaluation: The model demonstrates strong performance in generating consistent excess returns over the CSI 300 Index, indicating its effectiveness in capturing alpha[14] - Model Name: CSI 500 Enhanced Portfolio Model Construction Idea: Similar to the CSI 300 Enhanced Portfolio, this model focuses on enhancing the performance of the CSI 500 Index by applying quantitative strategies[8][14] Model Construction Process: Stocks are selected from the CSI 500 Index using quantitative factors, and the portfolio is optimized to achieve excess returns while maintaining a controlled tracking error[8][14] Model Evaluation: The model shows mixed results, with some periods of underperformance relative to the benchmark, suggesting room for improvement in factor selection or optimization[14] - Model Name: CSI 1000 Enhanced Portfolio Model Construction Idea: This model targets the CSI 1000 Index, aiming to generate excess returns through quantitative strategies tailored to small-cap stocks[8][14] Model Construction Process: The portfolio is constructed by selecting stocks from the CSI 1000 Index based on quantitative factors and optimizing for excess returns while managing tracking error[8][14] Model Evaluation: The model performs well, particularly in capturing alpha from small-cap stocks, with positive excess returns over the benchmark[14] - Model Name: GARP Portfolio Model Construction Idea: The GARP (Growth at a Reasonable Price) portfolio combines growth and valuation factors to identify stocks with strong growth potential at reasonable valuations[32] Model Construction Process: Stocks are selected based on a combination of growth metrics (e.g., earnings growth) and valuation metrics (e.g., PE ratio). The portfolio is optimized to balance growth and valuation considerations[32] Model Evaluation: The portfolio demonstrates strong performance, with significant excess returns over the CSI 300 Index, indicating the effectiveness of the GARP strategy[32] - Model Name: Small-Cap Value Portfolio Model Construction Idea: This portfolio focuses on small-cap stocks with attractive valuation metrics, aiming to capture value premiums in the small-cap segment[34][36] Model Construction Process: Stocks are selected based on valuation factors such as PB and PE ratios. The portfolio is optimized to maximize exposure to value factors while maintaining diversification[34][36] Model Evaluation: The portfolio shows mixed results, with one version underperforming the benchmark and another version generating positive excess returns, highlighting the importance of factor selection and portfolio construction[34][36] - Model Name: Small-Cap Growth Portfolio Model Construction Idea: This portfolio targets small-cap stocks with strong growth potential, leveraging growth factors to identify high-growth opportunities[38] Model Construction Process: Stocks are selected based on growth metrics such as earnings growth and revenue growth. The portfolio is optimized to maximize exposure to growth factors while maintaining diversification[38] Model Evaluation: The portfolio underperforms the benchmark, suggesting challenges in capturing growth premiums in the small-cap segment[38] Model Backtesting Results - CSI 300 Enhanced Portfolio: Weekly return 0.91%, monthly return 5.64%, annual return 5.64%, excess return over benchmark 3.44%[8][14] - CSI 500 Enhanced Portfolio: Weekly return 1.54%, monthly return 7.98%, annual return 7.98%, excess return over benchmark -2.30%[8][14] - CSI 1000 Enhanced Portfolio: Weekly return 2.56%, monthly return 8.89%, annual return 8.89%, excess return over benchmark 0.50%[8][14] - GARP Portfolio: Weekly return 1.23%, monthly return 4.89%, annual return 4.89%, excess return over benchmark 2.69%[32] - Small-Cap Value Portfolio 1: Weekly return 0.64%, monthly return 5.91%, annual return 5.91%, excess return over benchmark -0.60%[34] - Small-Cap Value Portfolio 2: Weekly return 2.84%, monthly return 7.92%, annual return 7.92%, excess return over benchmark 1.40%[36] - Small-Cap Growth Portfolio: Weekly return 1.20%, monthly return 6.21%, annual return 6.21%, excess return over benchmark -0.31%[38] Quantitative Factors and Construction Methods - Factor Name: Size Factor Factor Construction Idea: Captures the performance difference between small-cap and large-cap stocks[42] Factor Construction Process: Stocks are ranked by market capitalization, and the top 10% (small-cap) and bottom 10% (large-cap) are selected to form long and short portfolios, respectively. The size factor return is calculated as the difference between the long and short portfolio returns[42] Factor Evaluation: The size factor shows positive returns in the short term but mixed results over longer periods, indicating variability in its effectiveness[42] - Factor Name: PB Factor Factor Construction Idea: Measures the valuation premium or discount of stocks based on their price-to-book ratio[42] Factor Construction Process: Stocks are ranked by PB ratio, and the top 10% (low PB) and bottom 10% (high PB) are selected to form long and short portfolios, respectively. The PB factor return is calculated as the difference between the long and short portfolio returns[42] Factor Evaluation: The PB factor shows negative returns, suggesting challenges in capturing valuation premiums[42] - Factor Name: ROE Factor Factor Construction Idea: Identifies stocks with high profitability based on return on equity[53] Factor Construction Process: Stocks are ranked by ROE, and the top 10% (high ROE) and bottom 10% (low ROE) are selected to form long and short portfolios, respectively. The ROE factor return is calculated as the difference between the long and short portfolio returns[53] Factor Evaluation: The ROE factor demonstrates strong positive returns, indicating its effectiveness in identifying profitable stocks[53] Factor Backtesting Results - Size Factor: Weekly return 0.91%, annual return 0.16% (all-market), 5.33% (CSI 300), -9.74% (CSI 500), -2.90% (CSI 1000)[42][43] - PB Factor: Weekly return -1.83%, annual return -5.94% (all-market), -8.16% (CSI 300), -12.18% (CSI 500), -8.70% (CSI 1000)[42][43] - ROE Factor: Weekly return 2.47%, annual return 1.10% (all-market), 0.13% (CSI 300), -2.02% (CSI 500), 1.16% (CSI 1000)[53][54]
