Quantitative Models and Factor Construction Quantitative Models and Construction Methods 1. Model Name: Guosen JinGong Index Enhanced Portfolio - Model Construction Idea: The model aims to outperform its respective benchmarks by constructing enhanced portfolios based on multiple factors[10]. - Model Construction Process: The construction process includes three main components: return prediction, risk control, and portfolio optimization. The model is built using the following steps: 1. Return Prediction: Predicting the returns of stocks based on multiple factors. 2. Risk Control: Implementing constraints to control the risk exposure of the portfolio. 3. Portfolio Optimization: Optimizing the portfolio to maximize the expected return while adhering to the risk constraints[11]. - Model Evaluation: The model aims to consistently outperform its benchmarks, such as the CSI 300, CSI 500, CSI 1000, and CSI A500 indices[10][11]. Model Backtesting Results Guosen JinGong Index Enhanced Portfolio - CSI 300 Index Enhanced Portfolio: Weekly excess return 0.31%, annual excess return 3.36%[13]. - CSI 500 Index Enhanced Portfolio: Weekly excess return 1.11%, annual excess return -1.15%[13]. - CSI 1000 Index Enhanced Portfolio: Weekly excess return 1.60%, annual excess return 3.40%[13]. - CSI A500 Index Enhanced Portfolio: Weekly excess return 0.05%, annual excess return 3.77%[13]. Quantitative Factors and Construction Methods 1. Factor Name: EPTTM (Earnings to Price TTM) - Factor Construction Idea: This factor measures the earnings yield of a stock, which is the inverse of the price-to-earnings ratio[16]. - Factor Construction Process: - Formula: $ \text{EPTTM} = \frac{\text{Net Income TTM}}{\text{Market Capitalization}} $ - The numerator represents the net income over the trailing twelve months (TTM), and the denominator represents the market capitalization of the stock[16]. - Factor Evaluation: This factor is used to identify undervalued stocks with high earnings yield[16]. 2. Factor Name: Expected EPTTM - Factor Construction Idea: This factor uses analysts' consensus earnings estimates to calculate the expected earnings yield[16]. - Factor Construction Process: - Formula: $ \text{Expected EPTTM} = \frac{\text{Consensus Earnings Estimate}}{\text{Market Capitalization}} $ - The numerator represents the consensus earnings estimate for the next twelve months, and the denominator represents the market capitalization of the stock[16]. - Factor Evaluation: This factor helps in identifying stocks that are expected to have high earnings yield based on analysts' forecasts[16]. 3. Factor Name: BP (Book to Price) - Factor Construction Idea: This factor measures the book value yield of a stock, which is the inverse of the price-to-book ratio[16]. - Factor Construction Process: - Formula: $ \text{BP} = \frac{\text{Book Value}}{\text{Market Capitalization}} $ - The numerator represents the book value of the stock, and the denominator represents the market capitalization[16]. - Factor Evaluation: This factor is used to identify undervalued stocks with high book value yield[16].
