  • The report mentions the construction of A-share sentiment index based on market volatility and transaction volume changes, dividing the market into four quadrants. Only the quadrant with "volatility up - transaction down" shows significant negative returns, while others show positive returns. This sentiment index includes bottom warning and top warning signals[36][39][42] - The A-share sentiment index currently indicates bearish signals for both bottom warning (price) and top warning (volume), resulting in an overall bearish outlook for the market[39][42] - The A-share prosperity index is constructed using the YoY growth of net profit attributable to the parent company of the Shanghai Composite Index as the Nowcasting target. The index shows a slow upward trend, indicating the current upward cycle[29][33][35] - The prosperity index value as of September 19, 2025, is 21.21, which has increased by 15.79 compared to the end of 2023, confirming the upward cycle[33][35] - The report applies the BARRA factor model to construct ten major style factors for the A-share market, including SIZE, BETA, MOM, RESVOL, NLSIZE, BTOP, LIQUIDITY, EARNINGS_YIELD, GROWTH, and LVRG[57][58][60] - Among style factors, BETA factor shows high excess returns, while RESVOL factor demonstrates significant negative excess returns. High BETA and high growth stocks perform well, whereas non-linear size and value factors underperform[58][59][61] - The report analyzes the performance attribution of major indices using factor models. Indices like CSI 500, ChiNext Index, and Wind All A exhibit strong exposure to BETA factor, leading to favorable performance in style factors. Conversely, indices like Shanghai Composite Index and SSE 50 show weaker exposure to BETA factor, resulting in poor performance in style factors[66][67][73] - The CSI 500 enhanced portfolio has generated a cumulative excess return of 48.55% relative to the CSI 500 index since 2020, with a maximum drawdown of -5.73%. However, its weekly performance is -0.24%, underperforming the benchmark by 0.56%[45][47][49] - The SSE 300 enhanced portfolio has achieved a cumulative excess return of 38.48% relative to the SSE 300 index since 2020, with a maximum drawdown of -5.86%. Its weekly performance is -0.95%, underperforming the benchmark by 0.50%[52][53][55]
