• The report discusses a "Volume Timing Signal" model, which provides cautious signals for major broad-based indices as of May 9, 2025[23][24] - The "HS300 Upward Stock Ratio Sentiment Indicator" is introduced, calculated as the proportion of HS300 constituent stocks with positive returns over the past N days. This indicator is noted for capturing upward opportunities but has limitations in avoiding downside risks[24][25] - The "Momentum Sentiment Indicator" is derived by smoothing the upward stock ratio indicator over two different time windows (N1=50, N2=35). A bullish signal is generated when the short-term line exceeds the long-term line, and vice versa[27] - The "Moving Average Sentiment Indicator" is based on the eight moving averages (8, 13, 21, 34, 55, 89, 144, 233). The indicator assigns values (-1, 0, 1) based on the number of moving averages above or below the current price. A bullish signal is triggered when the price exceeds more than five moving averages[31][32] Backtesting Results of Models - Volume Timing Signal: All major indices (e.g., HS300, CSI500, CSI1000) are in a "cautious" state as of May 9, 2025[23][24] - HS300 Upward Stock Ratio Sentiment Indicator: The upward stock ratio is approximately 53% for the past week[25] - Momentum Sentiment Indicator: Both the fast and slow lines are trending downward, with the fast line falling below the slow line, indicating a cautious outlook[27] - Moving Average Sentiment Indicator: HS300 is currently in a non-bullish sentiment zone[37]
