Quantitative Factors and Construction Factor Construction and Methodology - Factor Name: Reversal Factor - Construction Idea: Captures the tendency of stocks to reverse their price movements over a short-term horizon[16][94] - Construction Process: Includes multiple sub-factors such as 1-month reversal (f_reversal_1m), relative average price reversal (f_reversal_avg_1m), and 1-month shift reversal (f_reserval_shift_1m). These sub-factors are calculated based on price movements and relative performance over the past month[166] - Evaluation: Demonstrates strong stock selection ability in the CSI 500 stock pool, with stable performance over the backtest period[94] - Factor Name: Volatility Factor - Construction Idea: Measures the variability of stock returns over different time horizons[16][67] - Construction Process: Includes sub-factors such as 1-month daily return volatility (vol_1m) and 3-month daily return volatility (vol_3m). These are calculated as the standard deviation of daily returns over the respective periods[166] - Evaluation: Exhibits excellent stock selection ability in the CSI 300 stock pool, with consistent performance in the CSI 500 stock pool over the backtest period[67] - Factor Name: Technical Factor - Construction Idea: Focuses on technical indicators such as price and turnover correlations to capture market trends[16][100] - Construction Process: Includes sub-factors like 1-month turnover-price correlation (corr_turnover_price_1m) and 1-month turnover-return correlation (corr_turnover_pct_chg_return_1m). These are calculated using correlation coefficients between turnover and price/return changes over the past month[166] - Evaluation: Shows outstanding performance in the CSI 500 stock pool, with notable contributions from the turnover-price correlation sub-factor[100] - Factor Name: Value Factor - Construction Idea: Identifies undervalued stocks based on fundamental valuation metrics[16][75] - Construction Process: Includes sub-factors such as inverse price-to-earnings ratio (ep), inverse price-to-book ratio (bp), and inverse price-to-sales ratio (sp). These are calculated as the reciprocal of the respective valuation metrics[166] - Evaluation: Demonstrates stable performance in the CSI 500 stock pool, with the ep sub-factor achieving strong results[75] - Factor Name: Liquidity Factor - Construction Idea: Measures the ease of trading stocks based on turnover and trading volume metrics[16][81] - Construction Process: Includes sub-factors like 3-month turnover standard deviation (f_turnover_std_3m) and 1-month turnover average (f_turnover_1m). These are calculated using turnover data over the respective periods[166] - Evaluation: Performs well in the CSI 500 stock pool, with the f_turnover_std_3m sub-factor showing notable stock selection ability[81] - Factor Name: Beta Factor - Construction Idea: Captures the sensitivity of a stock's returns to market movements[16][60] - Construction Process: Calculated as the slope coefficient of a regression of stock returns on market returns over a specified period[166] - Evaluation: Exhibits strong performance in the CSI 500 stock pool, with consistent results across the backtest period[60] - Factor Name: Earnings Factor - Construction Idea: Focuses on profitability metrics to identify fundamentally strong stocks[16][113] - Construction Process: Includes sub-factors like single-quarter ROE (roe_qua) and single-quarter net margin (net_margin_qua). These are derived from financial statement data[166] - Evaluation: Shows relatively strong performance in the CSI 500 stock pool, with roe_qua achieving the highest multi-layer excess return[113] - Factor Name: Growth Factor - Construction Idea: Measures the growth potential of stocks based on financial metrics[16][121] - Construction Process: Includes sub-factors like single-quarter EPS growth rate (eps_basic_qua_yoy) and single-quarter revenue growth rate (oper_rev_qua_yoy). These are calculated as year-over-year changes in the respective metrics[166] - Evaluation: Performs well in the CSI 500 stock pool, with eps_basic_qua_yoy showing the strongest results[121] - Factor Name: Quality Factor - Construction Idea: Evaluates the financial health and operational efficiency of companies[16][132] - Construction Process: Includes sub-factors like profit-to-debt ratio (profit_to_debt_qua) and inventory turnover ratio (inventory_turnover_qua). These are derived from financial statement data[166] - Evaluation: Demonstrates moderate performance, with profit_to_debt_qua achieving notable results in the CSI 500 stock pool[132] - Factor Name: Dividend Factor - Construction Idea: Focuses on dividend yield to identify income-generating stocks[16][139] - Construction Process: Includes sub-factors like trailing 12-month dividend yield (div_ratio_ttm), calculated as the ratio of dividends to stock price over the past year[166] - Evaluation: Performs well in the CSI 500 stock pool, with div_ratio_ttm achieving strong results[139] - Factor Name: Consensus Expectation Factor - Construction Idea: Captures market expectations based on analyst forecasts[16][144] - Construction Process: Includes sub-factors like consensus ROE (con_roe) and consensus revenue growth (con_or_yoy). These are derived from analyst forecast data[166] - Evaluation: Shows stable performance in the CSI 500 stock pool, with con_roe achieving the highest multi-layer excess return[144] --- Factor Backtest Results IC (Information Coefficient) - Reversal Factor: CSI 500 IC = 24.10%, CSI 1000 IC = 7.91%[18][94] - Volatility Factor: CSI 300 IC = 20.95%, CSI 1000 IC = 8.77%[18][67] - Technical Factor: CSI 500 IC = 22.63%, CSI 1000 IC = 6.90%[18][100] - Value Factor: CSI 500 IC = 18.32%, CSI 1000 IC = 3.80%[18][75] - Liquidity Factor: CSI 500 IC = 12.38%, CSI 1000 IC = 5.64%[18][81] - Beta Factor: CSI 500 IC = 29.68%, CSI 1000 IC = 9.51%[18][60] - Earnings Factor: CSI 500 IC = 0.43%, CSI 1000 IC = 2.48%[18][113] - Growth Factor: CSI 500 IC = 6.25%, CSI 1000 IC = 0.20%[18][121] - Quality Factor: CSI 500 IC = -0.60%, CSI 1000 IC = -1.32%[18][132] - Dividend Factor: CSI 500 IC = 1.57%, CSI 1000 IC = 2.97%[18][139] - Consensus Expectation Factor: CSI 500 IC = 13.30%, CSI 1000 IC = 8.45%[18][144] Multi-Layer Excess Return - Reversal Factor: CSI 500 = 2.61%, CSI 1000 = 1.61%[24][94] - Volatility Factor: CSI 300 = 0.59%, CSI 1000 = 0.96%[24][67] - Technical Factor: CSI 500 = 3.08%, CSI 1000 = 1.86%[24][100] - Value Factor: CSI 500 = 2.93%, CSI 1000 = 1.70%[24][75] - Liquidity Factor: CSI 500 = 1.03%, CSI 1000 = 0.49%[24][81] - Beta Factor: CSI 500 = 2.53%, CSI 1000 = 0.87%[24][60] - Earnings Factor: CSI 500 = 3.08%, CSI 1000 = 1.23%[24][113] - Growth Factor: CSI 500 = 1.95%, CSI 1000 = 0.71%[24][121] - Quality Factor: CSI 500 = 1.88%, CSI 1000 = 1.49%[24][132] - Dividend Factor: CSI 500 = 3.47%, CSI 1000 = 1.17%[24][139] - Consensus Expectation Factor: CSI 500 = 2.80%, CSI 1000 = 0.70%[24][144]
