Quantitative Models and Construction Methods 1. Model Name: Short-term Timing Model - Model Construction Idea: The model evaluates the market's short-term timing signals by analyzing macro fundamentals, valuation, sentiment, and liquidity indicators. It aims to provide a comprehensive view of market conditions and guide short-term investment decisions[12][17]. - Model Construction Process: 1. Macro Fundamentals: - Manufacturing PMI: A PMI value below 50 indicates weak manufacturing activity, providing a cautious signal. - Credit Pulse: The YoY growth rate of medium- and long-term RMB loans is at the 61.02% percentile over the past five years, indicating strong credit growth and providing an optimistic signal. - M1 Growth Rate: The filtered YoY growth rate of M1 is 5.23%, at the 96.61% percentile over the past five years, indicating strong M1 growth and providing an optimistic signal[12][17]. 2. Valuation: - PE Median: The current PE median of the A-share market is 45.50, at the 98.84% percentile over the past five years, signaling caution. - PB Median: The current PB median is 3.02, at the 96.94% percentile over the past five years, also signaling caution[12][17]. 3. Sentiment: - Beta Dispersion: The current beta dispersion is 8.66%, at the 96.61% percentile over the past five years, signaling caution. - Volume Sentiment Score: The score is 0.40, at the 74.52% percentile, indicating strong volume sentiment and providing an optimistic signal. - Volatility: The annualized volatility is 20.19%, at the 77.67% percentile, providing a neutral signal[13]. 4. Liquidity: - Money Market Rate: The rate is 0.00, at the 38.98% percentile, indicating relatively loose liquidity and providing an optimistic signal. - Exchange Rate Expectation: The indicator is -0.42%, at the 33.90% percentile, indicating a strong RMB against the USD and providing an optimistic signal. - Average 5-day Financing Amount: The value is 126.77 billion RMB, at the 97.85% percentile, signaling caution due to high leverage[13]. - Model Evaluation: The model effectively integrates multiple dimensions to provide a comprehensive short-term market outlook. It has demonstrated strong performance in historical backtests, with significant excess returns and reduced drawdowns compared to benchmarks[14]. 2. Model Name: Growth-Value Style Rotation Model - Model Construction Idea: This model identifies optimal allocation between growth and value styles based on macroeconomic cycles, valuation spreads, and sentiment indicators. It aims to capture excess returns through style rotation[24][25]. - Model Construction Process: 1. Macro Fundamentals: - Profit Cycle Slope: A steep profit cycle slope favors growth. The current slope is high, providing a 100% growth signal. - Interest Rate Cycle: A high interest rate cycle level favors value. The current level is high, providing a 100% value signal. - Credit Cycle: A strengthening credit cycle favors growth. The current cycle is strong, providing a 100% growth signal[24][26]. 2. Valuation: - PE Spread: The 5-year percentile of the growth-value PE spread is 45.11%, indicating mean reversion upward, favoring growth. - PB Spread: The 5-year percentile of the growth-value PB spread is 55.48%, also indicating mean reversion upward, favoring growth[24][26]. 3. Sentiment: - Turnover Spread: The 5-year percentile of the turnover spread is 38.13%, favoring value. - Volatility Spread: The 5-year percentile of the volatility spread is 94.76%, favoring a balanced allocation[24][26]. - Model Evaluation: The model has consistently outperformed its benchmark since 2012, with significant annualized excess returns and reduced drawdowns. It effectively captures style rotation opportunities[25][27]. 3. Model Name: Small-Cap vs. Large-Cap Style Rotation Model - Model Construction Idea: This model evaluates 11 effective rotation indicators to determine optimal allocation between small-cap and large-cap styles. It aims to exploit market inefficiencies and generate excess returns through size-based style rotation[29][30]. - Model Construction Process: 1. Indicators Favoring Small-Cap: - Increased financing purchase amounts. - Narrowing credit spreads. - Declining implied market volatility. - Rising PB divergence. - Recovery in small-cap trading volume[29][30]. 2. Indicators Favoring Large-Cap: - Declining small-cap theme sentiment. - High beta dispersion. - Rising R007 rates[29][30]. - Model Evaluation: The model has delivered positive excess returns every year since 2014, demonstrating its robustness and effectiveness in capturing size-based rotation opportunities[30]. --- Model Backtesting Results 1. Short-term Timing Model - Annualized Return: 17.99% - Annualized Volatility: 15.87% - Maximum Drawdown: 22.44% - Sharpe Ratio: 0.9959 - Excess Return (2025 YTD): 14.15%[14][19][22] 2. Growth-Value Style Rotation Model - Annualized Return: 13.22% - Annualized Volatility: 20.80% - Maximum Drawdown: 43.07% - Sharpe Ratio: 0.6056 - Excess Return (2025 YTD): 8.50%[25][27][28] 3. Small-Cap vs. Large-Cap Style Rotation Model - Annualized Return: 19.10% - Annualized Excess Return: 11.96% - Maximum Drawdown: 39.71% - Average Small-Cap Allocation (2025 YTD): 51.41% - Excess Return (2025 YTD): 4.44%[30][32]
