- 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).
