- **A-share multi-dimensional timing model**: The model evaluates the overall directional judgment of the A-share market using four dimensions: valuation, sentiment, funds, and technical indicators. Each dimension provides daily signals with values of 0, ±1, representing neutral, bullish, or bearish views. Valuation and sentiment dimensions adopt a mean-reversion logic, while funds and technical dimensions use trend-following logic. The final market view is determined by the sum of the scores across all dimensions [9][15][16] - **Style timing model for dividend style**: The model uses three indicators to time the dividend style relative to the CSI Dividend Index and CSI All Share Index. The indicators include relative momentum, 10Y-1Y term spread, and interbank pledged repo transaction volume. Each indicator provides daily signals with values of 0, ±1, representing neutral, bullish, or bearish views. The final view is based on the sum of the scores across all dimensions. When the model favors the dividend style, it fully allocates to the CSI Dividend Index; otherwise, it allocates to the CSI All Share Index [17][21] - **Style timing model for large-cap and small-cap styles**: The model uses momentum difference and turnover ratio difference between the CSI 300 Index and Wind Micro Cap Index to calculate the crowding scores for large-cap and small-cap styles. The model operates in two crowding zones: high crowding and low crowding. In high crowding zones, it uses a small-parameter dual moving average model to address potential style reversals. In low crowding zones, it uses a large-parameter dual moving average model to capture medium- to long-term trends [22][24][26] - **Sector rotation model**: The genetic programming-based sector rotation model selects the top five sectors with the highest multi-factor composite scores from 32 CITIC industry indices for equal-weight allocation. The model updates its factor library quarterly and rebalances weekly. The factors are derived using NSGA-II algorithm, which evaluates factor monotonicity and performance of long positions using |IC| and NDCG@5 metrics. The model combines multiple factors with weak collinearity into sector scores using greedy strategy and variance inflation factor [29][32][33][36] - **China domestic all-weather enhanced portfolio**: The portfolio is constructed using a macro factor risk parity framework, which emphasizes risk diversification across underlying macro risk sources rather than asset classes. The strategy involves three steps: macro quadrant classification and asset selection, quadrant portfolio construction and risk measurement, and risk budgeting to determine quadrant weights. The active allocation is based on macro expectation momentum indicators, which consider buy-side expectation momentum and sell-side expectation deviation momentum [38][41] --- Model Backtesting Results - **A-share multi-dimensional timing model**: Annualized return 24.97%, maximum drawdown -28.46%, Sharpe ratio 1.16, Calmar ratio 0.88, YTD return 37.73%, weekly return 0.00% [14] - **Dividend style timing model**: Annualized return 15.71%, maximum drawdown -25.52%, Sharpe ratio 0.85, Calmar ratio 0.62, YTD return 19.53%, weekly return -3.43% [20] - **Large-cap vs. small-cap style timing model**: Annualized return 26.01%, maximum drawdown -30.86%, Sharpe ratio 1.08, Calmar ratio 0.84, YTD return 64.58%, weekly return -2.22% [27] - **Sector rotation model**: Annualized return 33.33%, annualized volatility 17.89%, Sharpe ratio 1.86, maximum drawdown -19.63%, Calmar ratio 1.70, weekly return 0.14%, YTD return 39.41% [32] - **China domestic all-weather enhanced portfolio**: Annualized return 11.66%, annualized volatility 6.18%, Sharpe ratio 1.89, maximum drawdown -6.30%, Calmar ratio 1.85, weekly return 0.38%, YTD return 10.74% [42]

- The report introduces a "Three-dimensional Timing Framework" model, which is based on liquidity, divergence, and prosperity indicators. The model suggests that the market is in a consolidation phase, with liquidity trending downward, divergence trending upward, and prosperity remaining stable. The framework indicates a continued oscillating downward trend[7][12][14] - The "ETF Hotspot Trend Strategy" is constructed by selecting ETFs with both the highest and lowest price trends in an upward direction. The strategy further incorporates a support-resistance factor based on the steepness of the regression coefficients of the highest and lowest prices over the past 20 days. The top 10 ETFs with the highest turnover rate in the last 5 days relative to the last 20 days are selected to form a risk parity portfolio[28][31] - The "Capital Flow Resonance Strategy" is built using two factors: the financing margin factor and the active large-order capital factor. The financing margin factor is defined as the two-week rate of change of the 50-day average of the market-neutralized financing net buy minus the margin net buy (aggregated by individual stocks). The active large-order capital factor is defined as the net inflow ranking of the time-neutralized industry transaction volume over the past year, taking the 10-day average. The strategy excludes extreme head industries from the active large-order factor and applies a negative exclusion for the top industries in the financing margin factor. This adjustment improves the strategy's stability. Since 2018, the strategy has achieved an annualized excess return of 13.5% after fees, with an IR of 1.7. Last week, the strategy recorded a positive excess return of 4.96% relative to industry equal weight, with an absolute return of 2.37%[37][40] Model Backtesting Results - Three-dimensional Timing Framework: Historical performance indicates oscillating downward trends during periods of low liquidity and high divergence[14] - ETF Hotspot Trend Strategy: The strategy has achieved cumulative excess returns over the CSI 300 index this year[29][30] - Capital Flow Resonance Strategy: Since 2018, the strategy has achieved an annualized excess return of 13.5% after fees, with an IR of 1.7.

It recorded a positive return of 2.63% last week, indicating that high-beta portfolios outperformed low-beta portfolios[41][42] - **Growth Factor**: Reflects high-growth stocks favored by the market. It achieved a return of 1.51% last week[41][42] - **Size Factor**: Measures the performance of large-cap versus small-cap stocks. It recorded a positive return of 1.39% last week, with large-cap stocks outperforming small-cap stocks[41][42] - **Alpha Factors**: Includes institutional holdings and momentum factors. Notable factors include "Fund Holdings to Float Share Ratio" (1.33% weekly excess return), "Top Ten Mean Stock Value to NAV" (1.00% weekly excess return), and "1-Year-1-Month Momentum" (0.94% weekly excess return)[44][46] - **Growth and R&D Factors**: Factors such as "R&D Total Assets Ratio" (22.36% weekly excess return in CSI 300), "R&D Sales Revenue Ratio" (19.32% weekly excess return in CSI 300), and "Quarterly ROE YoY Difference" (19.43% weekly excess return in CSI 300) performed well across different indices, with stronger results in small-cap indices like CSI 1000[47][48] Factor Backtesting Results - **Beta Factor**: Annual return of 27.16%, monthly return of 2.83%, weekly return of 2.63%[42] - **Growth Factor**: Annual return of -0.45%, monthly return of 4.73%, weekly return of 1.51%[42] - **Size Factor**: Annual return of -23.40%, monthly return of 4.72%, weekly return of 1.39%[42] - **Alpha Factors**: Weekly excess returns range from 0.56% to 1.33%, with monthly excess returns ranging from 1.79% to 3.68%[44][46] - **Growth and R&D Factors**: Weekly excess returns in CSI 300 range from 13.71% to 22.36%, with higher returns observed in smaller-cap indices like CSI 1000[47][48]
