Quantitative Models and Construction Methods - Model Name: PB-ROE-50 Model Construction Idea: The model is based on the combination of Price-to-Book ratio (PB) and Return on Equity (ROE) to select stocks with high profitability and reasonable valuation[23] Model Construction Process: The PB-ROE-50 portfolio is constructed by selecting stocks with the top 50 combined scores of PB and ROE. The portfolio is rebalanced periodically, and adjustments are made based on the stock universe of different indices such as CSI 500 and CSI 800[23] Model Evaluation: The model demonstrates positive excess returns in specific stock pools, indicating its effectiveness in capturing value and profitability factors[23] - Model Name: Block Trade Portfolio Model Construction Idea: The model is based on the principle that stocks with higher block trade transaction ratios and lower 6-day transaction amount volatility tend to perform better subsequently[29] Model Construction Process: The portfolio is constructed by selecting stocks with high block trade transaction ratios and low 6-day transaction amount volatility. The portfolio is rebalanced monthly[29] Model Evaluation: The model captures the information embedded in block trades, but its performance varies depending on market conditions[29] - Model Name: Private Placement Portfolio Model Construction Idea: The model is based on the event-driven strategy of private placements, considering factors such as market capitalization, rebalancing cycles, and position control[35] Model Construction Process: The portfolio is constructed using the announcement date of private placements as the event trigger. Stocks are selected based on their market capitalization and other factors, and the portfolio is rebalanced periodically[35] Model Evaluation: The model's performance is influenced by regulatory changes and market sentiment, showing mixed results in different periods[35] --- Model Backtesting Results - PB-ROE-50 Model - CSI 500: Weekly excess return 0.76%, absolute return 1.71%; YTD excess return 2.84%, absolute return 27.48%[24] - CSI 800: Weekly excess return 0.21%, absolute return 1.40%; YTD excess return 15.39%, absolute return 36.63%[24] - All Market: Weekly excess return -0.09%, absolute return 0.68%; YTD excess return 18.22%, absolute return 43.75%[24] - Block Trade Portfolio - Weekly excess return -0.16%, absolute return 0.61%; YTD excess return 39.03%, absolute return 69.06%[30] - Private Placement Portfolio - Weekly excess return -2.30%, absolute return -1.55%; YTD excess return -5.43%, absolute return 15.00%[36] --- Quantitative Factors and Construction Methods - Factor Name: Profitability Factor (e.g., ROA, ROE) Factor Construction Idea: Measures the company's profitability and operational efficiency, such as Return on Assets (ROA) and Return on Equity (ROE)[12][13][14] Factor Construction Process: - ROA: Calculated as $ \text{ROA} = \frac{\text{Net Income}}{\text{Total Assets}} $ - ROE: Calculated as $ \text{ROE} = \frac{\text{Net Income}}{\text{Shareholder's Equity}} $ Factor Evaluation: Profitability factors generally show positive returns, especially in CSI 300 and CSI 500 stock pools[12][14] - Factor Name: Valuation Factor (e.g., PB, PE, EP) Factor Construction Idea: Reflects the valuation level of stocks, such as Price-to-Book ratio (PB), Price-to-Earnings ratio (PE), and Earnings Yield (EP)[12][14][16] Factor Construction Process: - PB: Calculated as $ \text{PB} = \frac{\text{Market Price per Share}}{\text{Book Value per Share}} $ - PE: Calculated as $ \text{PE} = \frac{\text{Market Price per Share}}{\text{Earnings per Share}} $ - EP: Calculated as $ \text{EP} = \frac{\text{Earnings per Share}}{\text{Market Price per Share}} $ Factor Evaluation: Valuation factors like PB and EP show significant positive returns in multiple industries[21] - Factor Name: Momentum Factor (e.g., 5-day Reversal, 1-month Momentum) Factor Construction Idea: Captures the trend-following or reversal behavior in stock prices over short-term periods[12][14][16] Factor Construction Process: - 5-day Reversal: Measures the return reversal over the past 5 days - 1-month Momentum: Measures the cumulative return over the past month Factor Evaluation: Momentum factors show mixed performance, with some negative returns in specific stock pools[12][14][16] - Factor Name: Liquidity Factor (e.g., Turnover Rate, Transaction Amount Volatility) Factor Construction Idea: Reflects the liquidity characteristics of stocks, such as turnover rate and transaction amount volatility[12][14][16] Factor Construction Process: - Turnover Rate: Calculated as $ \text{Turnover Rate} = \frac{\text{Trading Volume}}{\text{Total Shares Outstanding}} $ - Transaction Amount Volatility: Standard deviation of transaction amounts over a specific period Factor Evaluation: Liquidity factors generally show positive returns, especially in the CSI 500 and liquidity 1500 stock pools[12][14][16] --- Factor Backtesting Results - Profitability Factors - ROA: Weekly return 1.43% (CSI 300), 0.78% (CSI 500), 1.01% (Liquidity 1500)[12][14][16] - ROE: Weekly return 1.32% (CSI 300), 0.94% (CSI 500), 0.71% (Liquidity 1500)[12][14][16] - Valuation Factors - PB: Weekly return 0.67% (CSI 300), 0.77% (CSI 500), 1.06% (Liquidity 1500)[12][14][16] - EP: Weekly return -0.37% (CSI 300), 0.17% (CSI 500), 0.84% (Liquidity 1500)[12][14][16] - Momentum Factors - 5-day Reversal: Weekly return -1.25% (CSI 300), -0.48% (CSI 500), -1.44% (Liquidity 1500)[12][14][16] - 1-month Momentum: Weekly return 0.45% (CSI 300), 0.59% (CSI 500), 1.20% (Liquidity 1500)[12][14][16] - Liquidity Factors - Turnover Rate: Weekly return 0.75% (CSI 300), 1.68% (CSI 500), 0.84% (Liquidity 1500)[12][14][16] - Transaction Amount Volatility: Weekly return 0.47% (CSI 300), 1.01% (CSI 500), 0.56% (Liquidity 1500)[12][14][16]
