- 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.
