EBSCN·2025-05-25 07:41- Model Name: Volume Timing Model; Model Construction Idea: The model uses volume indicators to maintain a cautious view under the background of shrinking volume; Model Construction Process: The volume timing signal for major broad-based indices is calculated and maintained a cautious view as of May 23, 2025[1][2][22]; Model Evaluation: The model is effective in maintaining a cautious stance during periods of shrinking volume[22] - Factor Name: Upward Number Ratio of CSI 300; Factor Construction Idea: The factor calculates the proportion of stocks with positive returns in the CSI 300 index to judge market sentiment; Factor Construction Process: - CSI 300 Index N-day Upward Number Ratio = Number of CSI 300 Index constituent stocks with positive returns in the past N days / Total number of CSI 300 Index constituent stocks - The factor captures upward opportunities quickly and exits early during overheated market phases, but has limitations in avoiding downward risks[23][24][25]; Factor Evaluation: The factor is effective in capturing upward opportunities but has limitations in avoiding downward risks[24] - Factor Name: Moving Average Sentiment Indicator; Factor Construction Idea: The factor uses the eight moving average system to judge the trend state of the target index; Factor Construction Process: - Calculate the eight moving average values of the CSI 300 closing price with parameters 8, 13, 21, 34, 55, 89, 144, 233 - Assign values to the eight moving average indicator based on the interval value: -1 for intervals 1/2/3, 0 for intervals 4/5/6, and 1 for intervals 7/8/9 - When the current price exceeds the eight moving average indicator value in more than 5 cases, it indicates a bullish view on the CSI 300 index[27][31][32]; Factor Evaluation: The factor is effective in indicating the trend state of the CSI 300 index[34] - Factor Name: Cross-sectional Volatility; Factor Construction Idea: The factor measures the cross-sectional volatility of index constituent stocks to evaluate the Alpha environment; Factor Construction Process: - Calculate the cross-sectional volatility of CSI 300, CSI 500, and CSI 1000 index constituent stocks - Recent cross-sectional volatility of CSI 300 and CSI 500 index constituent stocks has decreased, indicating a worse short-term Alpha environment; CSI 1000 index constituent stocks' cross-sectional volatility has increased, indicating a better short-term Alpha environment[35][36][38]; Factor Evaluation: The factor is effective in evaluating the Alpha environment based on cross-sectional volatility[38] - Factor Name: Time Series Volatility; Factor Construction Idea: The factor measures the time series volatility of index constituent stocks to evaluate the Alpha environment; Factor Construction Process: - Calculate the time series volatility of CSI 300, CSI 500, and CSI 1000 index constituent stocks - Recent time series volatility of CSI 300, CSI 500, and CSI 1000 index constituent stocks has decreased, indicating a worse short-term Alpha environment[39][41]; Factor Evaluation: The factor is effective in evaluating the Alpha environment based on time series volatility[41] Model Backtest Results - Volume Timing Model, cautious view for all major broad-based indices as of May 23, 2025[23] Factor Backtest Results - Upward Number Ratio of CSI 300, recent ratio around 56%[24] - Moving Average Sentiment Indicator, short-term bullish view on CSI 300 index[34] - Cross-sectional Volatility, recent values for CSI 300: 1.75%, CSI 500: 2.04%, CSI 1000: 2.41%[38] - Time Series Volatility, recent values for CSI 300: 0.56%, CSI 500: 0.44%, CSI 1000: 0.27%[41]
