• The "A-Share Market Timing Model" evaluates the overall directional judgment of the A-share market using four dimensions: valuation, sentiment, funds, and technicals. The model generates daily signals with values of 0, ±1, representing neutral, bullish, and bearish views, respectively. The model's logic includes mean reversion for valuation and sentiment, and trend continuation for funds and technicals[2][9][15] - The "Style Timing Model" favors a barbell structure of dividend and small-cap styles. For the dividend style, the model uses the relative momentum of the CSI Dividend Index to the CSI All Share Index, the 10Y-1Y term spread, and the interbank pledged repo transaction volume. For the small-cap style, the model employs a trend model based on the difference in momentum and trading volume between small-cap and large-cap stocks[3][17][21] - The "Industry Rotation Model" uses genetic programming to directly extract factors from the volume, price, and valuation characteristics of industry indices. The model updates its factor library quarterly and rebalances weekly, selecting the top five industries with the highest multi-factor composite scores for equal-weight allocation[4][29][34] - The "China Domestic All-Weather Enhanced Portfolio" employs a macro factor risk parity framework, selecting four macro risk sources: growth above/below expectations and inflation above/below expectations. The model actively overweights favored quadrants based on macro expectation momentum, adjusting monthly[5][39][42] - The "A-Share Market Timing Model" achieved a year-to-date return of 36.03%, with an excess return of 8.86% over the Wind All A Index, which had a return of 27.18%[2][9] - The "Style Timing Model" for the dividend style yielded a year-to-date return of 25.04%, with an excess return of 7.83% over the benchmark, which had a return of 17.21%[17][20] - The "Style Timing Model" for the small-cap style achieved a year-to-date return of 78.29%, with an excess return of 30.25% over the benchmark, which had a return of 48.04%[22][27] - The "Industry Rotation Model" achieved a year-to-date return of 40.67%, outperforming the industry equal-weight benchmark by 17.96 percentage points[4][32] - The "China Domestic All-Weather Enhanced Portfolio" achieved a year-to-date return of 11.10%, with a Sharpe ratio of 2.22, a maximum drawdown of 2.67%, and a Calmar ratio of 5.15[5][40][43]
