- Model Name: CSI 500 Enhanced Portfolio; Model Construction Idea: The model aims to outperform the CSI 500 index by selecting stocks with higher expected returns based on quantitative strategies[2][58] - Model Construction Process: The model uses a quantitative strategy to select stocks from the CSI 500 index. The portfolio's performance is evaluated based on its excess return over the CSI 500 index. The specific construction process involves selecting stocks with higher expected returns and adjusting the portfolio weights accordingly[58][61] - Model Evaluation: The model has shown a significant excess return over the CSI 500 index, indicating its effectiveness in enhancing returns[58][61] - Model Name: CSI 300 Enhanced Portfolio; Model Construction Idea: The model aims to outperform the CSI 300 index by selecting stocks with higher expected returns based on quantitative strategies[2][65] - Model Construction Process: The model uses a quantitative strategy to select stocks from the CSI 300 index. The portfolio's performance is evaluated based on its excess return over the CSI 300 index. The specific construction process involves selecting stocks with higher expected returns and adjusting the portfolio weights accordingly[65][66] - Model Evaluation: The model has shown a significant excess return over the CSI 300 index, indicating its effectiveness in enhancing returns[65][66] - Factor Name: Value Factor; Factor Construction Idea: The value factor aims to capture the excess returns of stocks that are undervalued relative to their fundamentals[2][70] - Factor Construction Process: The value factor is constructed by ranking stocks based on their valuation ratios, such as price-to-book (P/B) and price-to-earnings (P/E) ratios. Stocks with lower valuation ratios are considered undervalued and are given higher weights in the factor portfolio[70][76] - Factor Evaluation: The value factor has shown high excess returns, indicating its effectiveness in capturing the returns of undervalued stocks[70][76] - Factor Name: Residual Volatility Factor; Factor Construction Idea: The residual volatility factor aims to capture the excess returns of stocks with lower idiosyncratic risk[2][70] - Factor Construction Process: The residual volatility factor is constructed by ranking stocks based on their residual volatility, which is the volatility of the stock's returns unexplained by market movements. Stocks with lower residual volatility are given higher weights in the factor portfolio[70][76] - Factor Evaluation: The residual volatility factor has shown high excess returns, indicating its effectiveness in capturing the returns of low-risk stocks[70][76] - Factor Name: Non-linear Size Factor; Factor Construction Idea: The non-linear size factor aims to capture the excess returns of stocks with specific size characteristics that are not linearly related to market capitalization[2][70] - Factor Construction Process: The non-linear size factor is constructed by ranking stocks based on their non-linear size characteristics, which may include measures such as the square or cube of market capitalization. Stocks with specific size characteristics are given higher weights in the factor portfolio[70][76] - Factor Evaluation: The non-linear size factor has shown significant negative excess returns, indicating its ineffectiveness in capturing the returns of stocks with specific size characteristics[70][76] Model Backtest Results - CSI 500 Enhanced Portfolio, Excess Return: 46.94%, Maximum Drawdown: -4.99%[58][61] - CSI 300 Enhanced Portfolio, Excess Return: 31.61%, Maximum Drawdown: -5.86%[65][66] Factor Backtest Results - Value Factor, Excess Return: High[70][76] - Residual Volatility Factor, Excess Return: High[70][76] - Non-linear Size Factor, Excess Return: Significant Negative[70][76]
