- The report discusses the "Volume Timing Signal" model, which is used to gauge market sentiment based on trading volume. The model's construction involves analyzing the volume of trades to determine whether the market sentiment is optimistic or cautious. As of August 29, 2025, the volume timing signals for the CSI 1000, ChiNext Index, and Beijing 50 Index are cautious, while other major broad-based indices show optimistic signals[26][27] - The "Number of Rising Stocks in CSI 300" sentiment indicator is another model mentioned in the report. This model calculates the proportion of stocks in the CSI 300 index that have positive returns over a given period. The formula is: $$ \text{Proportion of Rising Stocks in CSI 300 over N days} = \frac{\text{Number of CSI 300 stocks with positive returns over N days}}{\text{Total number of CSI 300 stocks}} $$ This indicator helps capture market sentiment by identifying periods when a majority of stocks are performing well, which often indicates market optimism. The recent value of this indicator is around 94%[27][28][30] - The "Moving Average Sentiment Indicator" is also discussed. This model uses the eight moving averages of the CSI 300 index to determine market trends. The moving averages used are 8, 13, 21, 34, 55, 89, 144, and 233 days. The model assigns values based on the number of moving averages that the current price exceeds. If the current price exceeds more than five moving averages, the market sentiment is considered optimistic. The formula for the moving average sentiment indicator is: $$ \text{Number of Moving Averages Exceeded by Current Price} $$ The recent analysis shows that the CSI 300 index is in an optimistic sentiment zone[35][36][37] - The "Cross-sectional Volatility" factor is used to measure the dispersion of stock returns within an index. Higher cross-sectional volatility indicates a better environment for alpha generation. The recent values for cross-sectional volatility are: - CSI 300: 1.76% - CSI 500: 1.91% - CSI 1000: 2.23% These values suggest that the short-term alpha environment is improving[41][43] - The "Time-series Volatility" factor measures the volatility of individual stock returns over time. Higher time-series volatility also indicates a better environment for alpha generation. The recent values for time-series volatility are: - CSI 300: 0.53% - CSI 500: 0.38% - CSI 1000: 0.22% These values suggest that the short-term alpha environment is improving[44][46] Model and Factor Performance Metrics - Volume Timing Signal: - CSI 1000: Cautious - ChiNext Index: Cautious - Beijing 50 Index: Cautious - Other major indices: Optimistic[26][27] - Number of Rising Stocks in CSI 300: - Recent value: 94%[27][28][30] - Moving Average Sentiment Indicator: - Recent sentiment: Optimistic[35][36][37] - Cross-sectional Volatility: - CSI 300: 1.76% - CSI 500: 1.91% - CSI 1000: 2.23%[41][43] - Time-series Volatility: - CSI 300: 0.53% - CSI 500: 0.38% - CSI 1000: 0.22%[44][46]
