• The report mentions the construction of the A-share prosperity index, which is based on the year-on-year net profit of the Shanghai Composite Index as the Nowcasting target. The index is currently in an upward cycle, with a value of 20.44 as of October 24, 2025, showing an increase of 15.02 compared to the end of 2023[29][32][33] - The report discusses the A-share sentiment index, which is constructed using market volatility and trading volume changes. The index divides the market into four quadrants based on the direction of volatility and trading volume changes. Among these quadrants, only the "volatility up-trading volume down" quadrant shows significant negative returns, while the others show significant positive returns. The sentiment index includes bottom warning and top warning signals. Currently, the bottom signal indicates bearishness, the top signal also indicates bearishness, and the overall sentiment signal is bearish[33][36][38] - The report analyzes style factors using the BARRA factor model, which includes ten categories: size (SIZE), beta (BETA), momentum (MOM), residual volatility (RESVOL), non-linear size (NLSIZE), valuation (BTOP), liquidity (LIQUIDITY), earnings yield (EARNINGS_YIELD), growth (GROWTH), and leverage (LVRG). Recent market trends show that liquidity factors are positively correlated with beta, momentum, and residual volatility, while valuation factors are negatively correlated with beta, residual volatility, and liquidity. Among style factors, beta factors have shown high excess returns, while non-linear size factors have shown significant negative excess returns. High-leverage stocks have performed well recently, while residual volatility and non-linear size factors have underperformed[57][58][60] - The report evaluates the performance of enhanced index portfolios.
