- The report discusses a "Momentum Sentiment Indicator" model, which is used for market timing based on the proportion of stocks with positive returns in the CSI 300 Index over a specific period. The model calculates the proportion of stocks with positive returns over N days and applies smoothing with two moving averages (N1 and N2). When the short-term moving average exceeds the long-term moving average, it signals a bullish market sentiment[26][27][29] - The "Moving Average Sentiment Indicator" is another model that evaluates the CSI 300 Index's sentiment by comparing the closing price with eight moving averages (parameters: 8, 13, 21, 34, 55, 89, 144, 233). If the closing price exceeds more than five of these moving averages, the model signals a bullish sentiment[33][34] - The report evaluates the "Cross-Sectional Volatility" factor, which measures the dispersion of stock returns within an index. A higher cross-sectional volatility indicates a favorable alpha environment.

It calculates the standard deviation of cross-sectional returns within a fund portfolio. A lower standard deviation indicates higher clustering, while a higher standard deviation suggests fund divergence. The report notes a slight decrease in divergence in the most recent week[80][83] - The "Momentum Sentiment Indicator" model's backtest results show that the fast line is currently above the slow line, indicating a bullish sentiment for the CSI 300 Index[27][29] - The "Moving Average Sentiment Indicator" model's backtest results indicate that the CSI 300 Index is currently in a positive sentiment zone, as the closing price exceeds more than five of the eight moving averages[34][36] - The "Cross-Sectional Volatility" factor's recent values are as follows: CSI 300 (1.98%), CSI 500 (2.12%), and CSI 1000 (2.37%) for the past quarter, with respective percentile rankings of 69.77%, 69.84%, and 65.34% over the past two years[41] - The "Time-Series Volatility" factor's recent values are as follows: CSI 300 (0.62%), CSI 500 (0.44%), and CSI 1000 (0.24%) for the past quarter, with respective percentile rankings of 58.18%, 74.60%, and 57.37% over the past two years[44] - The "Fund Concentration Divergence" indicator shows a slight decrease in divergence, with fund and stock excess returns improving week-over-week[80][83]
