Quantitative Factors and Construction Methods 1. Factor Name: "偏锋涨跌幅" (Skewed Momentum) - **Factor Construction Idea**: This factor captures the "excess momentum" of individual stocks relative to the market during specific intraday periods, aiming to identify stocks prone to overreaction and subsequent reversal[1][10][13] - **Factor Construction Process**: 1. **Momentum Benchmark**: Calculate the average return of all rising or falling stocks in the market for each minute, serving as the "positive momentum benchmark" and "negative momentum benchmark"[13] 2. **Deviation**: For each stock and each minute, compute the difference between the stock's 1-minute return and the corresponding momentum benchmark. If the stock's return is zero or no stocks share the same direction, the deviation is set to zero[13] 3. **Skewness of Deviation**: Calculate the skewness of deviations across all stocks in the market for each minute. Positive skewness indicates a higher proportion of "outlier rising" or "outlier falling" stocks. Aggregate the logarithmic deviations during "momentum periods" (when skewness > 0) for each stock to derive a daily factor[13] 4. **Low-Frequency Conversion**: At the end of each month, calculate the standard deviation of the daily factor over the past 20 days to obtain the "偏锋涨跌幅" factor[13] - **Factor Evaluation**: This factor effectively captures intraday overreaction and helps identify stocks with potential for reversal[10][13] 2. Factor Name: "量涌波动率" (Volume Surge Volatility) - **Factor Construction Idea**: This factor measures the stability of returns within intraday periods defined by volume peaks, reflecting the impact of different investor sentiments on stock returns[17][23] - **Factor Construction Process**: 1. **Segment Division**: Use a recursive binary method to divide the intraday period into segments based on volume peaks. Exclude the first 10 minutes of trading to avoid distortions from high activity[23] - If a segment contains at least 3 minutes, divide it into two sub-segments based on the highest volume minute (excluding the first and last minutes)[23] - If a segment contains 2 minutes, divide it into two 1-minute segments[23] - If a segment contains only 1 minute, no further division is performed[23] 2. **Volatility Calculation**: Compute the standard deviation of returns for each segment as the daily factor value[23] 3. **Low-Frequency Conversion**: Standardize the daily factor and calculate the standard deviation over the past 20 days to derive the "量涌波动率" factor[23] - **Factor Evaluation**: This factor captures the stability of returns influenced by different investor sentiments, effectively identifying stocks with higher or lower future returns based on intraday volatility patterns[17][24] 3. Factor Name: "动量脉冲" (Momentum Pulse) - **Factor Construction Idea**: This composite factor combines "偏锋涨跌幅" and "量涌波动率" equally to enhance the precision of capturing intraday momentum and reversal effects[27][28] - **Factor Construction Process**: 1. Combine the "偏锋涨跌幅" and "量涌波动率" factors with equal weights[28] 2. Perform monthly frequency backtesting to evaluate the factor's performance[28] - **Factor Evaluation**: The composite factor demonstrates strong performance in capturing intraday momentum and reversal effects, with consistent positive excess returns across different market conditions[28][47] --- Factor Backtesting Results 1. "偏锋涨跌幅" Factor - **IC Mean**: 6.29%[14] - **Rank IC Mean**: 9.20%[14] - **Annualized Long-Short Return**: 29.13%[14] - **Annualized Long-Short Sharpe Ratio**: 2.25[14] - **Annualized Long-Only Excess Return**: 7.46%[14] - **Annualized Long-Only Sharpe Ratio**: 1.52[14] 2.
