- The RPV factor (Renewed Correlation of Price and Volume) integrates intraday and overnight information by dividing price-volume into four quadrants. It leverages monthly IC averages to identify reversal and momentum effects. The factor incorporates "volume" information in correlation form, optimizing intraday and overnight price-volume relationships to create a robust selection factor[6][1][7] - The SRV factor (Smart Renewed Volume) splits intraday price movements into morning and afternoon segments, calculating minute-level "smart" indicators. It identifies the 20% of afternoon minutes with the highest "smart" indicator values as informed trading periods. The factor uses turnover rates during these periods and replaces overnight turnover rates with the last 30-minute turnover rate of the previous day, combining the best-performing intraday and overnight price-volume correlation factors[6][1][7] - The RPV factor achieved an annualized return of 14.44%, annualized volatility of 7.71%, IR of 1.87, monthly win rate of 72.46%, and maximum drawdown of 10.63% during the backtest period from January 2014 to July 2025[7][10] - The SRV factor achieved an annualized return of 17.15%, annualized volatility of 6.49%, IR of 2.64, monthly win rate of 74.64%, and maximum drawdown of 3.74% during the backtest period from January 2014 to July 2025[7][10] - In July 2025, the RPV factor's 10-group long portfolio returned 5.18%, the short portfolio returned 5.58%, and the long-short portfolio returned -0.39%[10] - In July 2025, the SRV factor's 10-group long portfolio returned 5.66%, the short portfolio returned 5.81%, and the long-short portfolio returned -0.15%[10]

- Model Name: RPV (Renewed Correlation of Price and Volume); Model Construction Idea: The RPV factor integrates intraday and overnight information by dividing price and volume into four quadrants, effectively identifying the reversal and momentum effects of price-volume correlation factors through the monthly IC mean; Model Construction Process: The RPV factor is constructed by combining the best representatives of intraday and overnight price-volume correlations, incorporating "trading volume" information in the form of correlation, and completing information integration; Model Evaluation: The RPV factor is novel and effective[1][6][7] - Model Name: SRV (Smart Relative Volume); Model Construction Idea: The SRV factor splits intraday price changes into morning and afternoon changes, calculates the "smart" indicator by minute, and uses the correlation coefficient between the afternoon "smart" turnover rate and afternoon price changes; Model Construction Process: The SRV factor combines the more effective intraday price-volume correlation factor and the overnight price-volume correlation factor, where the turnover rate is replaced by the turnover rate of the last half-hour of the previous day, which has a higher proportion of informed trading; Model Evaluation: The SRV factor performs better than the RPV factor[1][6][7] Model Backtest Results - RPV Model, Annualized Return: 14.69%, Annualized Volatility: 7.75%, IR: 1.90, Monthly Win Rate: 72.79%, Maximum Drawdown: 10.63%[1][7][10] - SRV Model, Annualized Return: 17.48%, Annualized Volatility: 6.50%, IR: 2.69, Monthly Win Rate: 75.74%, Maximum Drawdown: 3.74%[1][7][10] Factor Construction and Evaluation - Factor Name: RPV; Factor Construction Idea: The RPV factor integrates intraday and overnight information by dividing price and volume into four quadrants, effectively identifying the reversal and momentum effects of price-volume correlation factors through the monthly IC mean; Factor Construction Process: The RPV factor is constructed by combining the best representatives of intraday and overnight price-volume correlations, incorporating "trading volume" information in the form of correlation, and completing information integration; Factor Evaluation: The RPV factor is novel and effective[1][6][7] - Factor Name: SRV; Factor Construction Idea: The SRV factor splits intraday price changes into morning and afternoon changes, calculates the "smart" indicator by minute, and uses the correlation coefficient between the afternoon "smart" turnover rate and afternoon price changes; Factor Construction Process: The SRV factor combines the more effective intraday price-volume correlation factor and the overnight price-volume correlation factor, where the turnover rate is replaced by the turnover rate of the last half-hour of the previous day, which has a higher proportion of informed trading; Factor Evaluation: The SRV factor performs better than the RPV factor[1][6][7] Factor Backtest Results - RPV Factor, Annualized Return: 14.69%, Annualized Volatility: 7.75%, IR: 1.90, Monthly Win Rate: 72.79%, Maximum Drawdown: 10.63%[1][7][10] - SRV Factor, Annualized Return: 17.48%, Annualized Volatility: 6.50%, IR: 2.69, Monthly Win Rate: 75.74%, Maximum Drawdown: 3.74%[1][7][10]
