Quantitative Models and Construction - **Model Name**: Volume Model **Construction Idea**: This model evaluates market trends based on trading volume changes over time [12][72] **Construction Process**: The model analyzes the trading volume of broad-based indices to determine short-term market sentiment. It transitions between "bullish," "neutral," and "bearish" signals based on volume dynamics [12][72] **Evaluation**: The model is effective in capturing short-term market sentiment but may require integration with other indicators for comprehensive analysis [12][72] - **Model Name**: Low Volatility Model **Construction Idea**: This model assesses market conditions by analyzing the volatility of indices [12][72] **Construction Process**: The model calculates the historical volatility of indices and assigns a "neutral" signal when volatility remains within a predefined range [12][72] **Evaluation**: The model provides a stable perspective on market conditions but may lag in highly volatile environments [12][72] - **Model Name**: Intelligent Algorithm Model (CSI 300 and CSI 500) **Construction Idea**: This model uses machine learning algorithms to predict market trends for specific indices [12][72] **Construction Process**: The model applies advanced algorithms to historical price and volume data, generating "bullish" signals for the CSI 300 and CSI 500 indices [12][72] **Evaluation**: The model demonstrates strong predictive capabilities for these indices, particularly in short-term scenarios [12][72] - **Model Name**: Limit-Up/Limit-Down Model **Construction Idea**: This model evaluates market sentiment based on the frequency of limit-up and limit-down events [13][73] **Construction Process**: The model tracks the number of stocks hitting daily price limits and assigns a "neutral" signal when no significant trend is observed [13][73] **Evaluation**: The model is useful for identifying extreme market conditions but may not capture subtle trends [13][73] - **Model Name**: Long-Term Momentum Model **Construction Idea**: This model identifies long-term trends by analyzing momentum indicators [14][74] **Construction Process**: The model calculates momentum metrics for indices like the SSE 50, which recently transitioned to a "bullish" signal [14][74] **Evaluation**: The model is effective for long-term trend analysis but may miss short-term fluctuations [14][74] - **Model Name**: A-Share Comprehensive Weapon V3 Model **Construction Idea**: This composite model integrates multiple signals to provide an overall market outlook [15][75] **Construction Process**: The model aggregates signals from various short-term, medium-term, and long-term models, currently indicating a "bearish" outlook [15][75] **Evaluation**: The model offers a holistic view but may dilute the impact of individual signals [15][75] - **Model Name**: HK Stock Turnover-to-Volatility Model **Construction Idea**: This model evaluates the Hong Kong market by analyzing turnover relative to volatility [16][76] **Construction Process**: The model calculates the ratio of turnover to volatility, currently signaling a "bullish" outlook for the Hang Seng Index [16][76] **Evaluation**: The model is effective for medium-term analysis but may require additional factors for short-term predictions [16][76] Model Backtesting Results - **Volume Model**: Short-term signal transitioned to "neutral" for most broad-based indices [12][72] - **Low Volatility Model**: Maintains a "neutral" signal [12][72] - **Intelligent Algorithm Model**: "Bullish" signals for CSI 300 and CSI 500 indices [12][72] - **Limit-Up/Limit-Down Model**: "Neutral" signal for medium-term analysis [13][73] - **Long-Term Momentum Model**: SSE 50 transitioned to "bullish" [14][74] - **A-Share Comprehensive Weapon V3 Model**: Overall "bearish" signal [15][75] - **HK Stock Turnover-to-Volatility Model**: "Bullish" signal for the Hang Seng Index [16][76]

Quantitative Models and Construction Methods 1. Model Name: PB-ROE-50 Strategy - **Model Construction Idea**: The core idea is to identify expectation gaps in the market and enhance portfolio returns by incorporating surprise expectation factors (e.g., SUE, ROE YoY growth) [31] - **Model Construction Process**: - Based on the PB-ROE pricing model derived by Wilcox (1984), stocks with significant expectation gaps are selected to form a pool - From this pool, 50 stocks are selected using factors such as standardized unexpected earnings (SUE) and ROE YoY growth to construct the PB-ROE-50 portfolio [31] - **Model Evaluation**: The strategy achieved positive excess returns across different stock pools, demonstrating its effectiveness in capturing market expectation gaps [31] 2. Model Name: Institutional Research Strategy - **Model Construction Idea**: This strategy leverages public and private institutional research data to extract alpha by analyzing the frequency of company visits and stock performance relative to benchmarks before the visits [39] - **Model Construction Process**: - Public Research Selection: Stocks are selected based on the number of visits by public institutions and their relative performance to the CSI 800 index - Private Research Tracking: Stocks are selected based on the number of visits by well-known private institutions and their relative performance to the CSI 800 index [39] - **Model Evaluation**: Both public and private research strategies generated significant positive excess returns, indicating the value of institutional research data in stock selection [39] --- Model Backtesting Results 1. PB-ROE-50 Strategy - **Excess Return (YTD)**: - CSI 500: 3.62% - CSI 800: 9.73% - All Market: 10.36% [35] - **Excess Return (Last Month)**: - CSI 500: 0.59% - CSI 800: 2.91% - All Market: 2.34% [35] - **Absolute Return (YTD)**: - CSI 500: 12.68% - CSI 800: 15.10% - All Market: 20.07% [35] - **Absolute Return (Last Month)**: - CSI 500: 5.88% - CSI 800: 7.02% - All Market: 6.77% [35] 2. Institutional Research Strategy - **Excess Return (YTD)**: - Public Research: 7.03% - Private Research: 18.00% [42] - **Excess Return (Last Month)**: - Public Research: 3.66% - Private Research: 5.58% [42] - **Absolute Return (YTD)**: - Public Research: 12.26% - Private Research: 23.77% [42] - **Absolute Return (Last Month)**: - Public Research: 7.80% - Private Research: 9.80% [42] --- Quantitative Factors and Construction Methods 1. Factor Name: Percentage of Advancing Stocks (Market Sentiment Indicator) - **Factor Construction Idea**: Strong-performing stocks often exhibit a demonstration effect, and the percentage of advancing stocks can reflect market sentiment. A higher percentage indicates optimism, while an overly high percentage may signal overheating [12] - **Factor Construction Process**: - Formula: $ \text{Percentage of Advancing Stocks (N days)} = \frac{\text{Number of CSI 300 stocks with positive returns over N days}}{\text{Total number of CSI 300 stocks}} $ - The indicator is smoothed using two moving averages (N1 = 50, N2 = 35). When the short-term average (fast line) exceeds the long-term average (slow line), it signals a bullish market sentiment [12][13][15] - **Factor Evaluation**: The indicator effectively captures upward opportunities but struggles to avoid risks in declining markets. It may also miss gains during prolonged market exuberance [12] 2. Factor Name: Moving Average Sentiment Indicator - **Factor Construction Idea**: This factor uses an eight-moving-average system to assess the trend state of the CSI 300 index. By assigning values to different ranges of the moving average, the relationship between indicator states and index trends becomes clearer [20] - **Factor Construction Process**: - Calculate the eight moving averages of the CSI 300 closing price (parameters: 8, 13, 21, 34, 55, 89, 144, 233) - Assign values based on the range of the moving averages: - Range 1/2/3: -1 - Range 4/5/6: 0 - Range 7/8/9: 1 - A bullish signal is generated when the number of moving averages below the current price exceeds 5 [20][26] - **Factor Evaluation**: The indicator provides a clear relationship between sentiment states and index trends, aiding in market timing [20] 3. Factor Name: Leverage Ratios (Debt Indicators) - **Factor Construction Idea**: High leverage ratios indicate greater debt pressure and liquidity risks. Three calculation methods (traditional, strict, and relaxed) are used to assess leverage comprehensively [44] - **Factor Construction Process**: - Traditional Leverage Ratio: $ \text{Traditional Leverage Ratio} = \frac{\text{Short-term Debt + Long-term Debt + Bonds Payable}}{\text{Total Assets}} $ - Strict Leverage Ratio: $ \text{Strict Leverage Ratio} = \frac{\text{Short-term Debt + Interest Payable + Financial Liabilities + Short-term Bonds + Lease Liabilities + Long-term Debt + Bonds Payable + Long-term Payables}}{\text{Total Assets}} $ - Relaxed Leverage Ratio: $ \text{Relaxed Leverage Ratio} = \frac{\text{Strict Leverage Components + Other Current Liabilities + Liabilities Held for Sale + Non-current Liabilities Due Within One Year}}{\text{Total Assets}} $ [44] - **Factor Evaluation**: The relaxed leverage ratio provides more opportunities for short positions compared to traditional metrics [44] 4. Factor Name: Financial Cost Burden Ratio - **Factor Construction Idea**: This factor measures the pressure of interest payments on companies by isolating interest expenses from financial costs, providing a clearer view of financial burdens [48] - **Factor Construction Process**: - Formula: $ \text{Financial Cost Burden Ratio} = \frac{\text{Interest Expenses}}{\text{EBIT}} $ [48] - **Factor Evaluation**: The factor effectively highlights companies with high financial stress, aiding in risk identification [48] --- Factor Backtesting Results 1. Percentage of Advancing Stocks - **Latest Value**: Above 70% as of July 31, 2025, indicating high market sentiment [12] 2. Moving Average Sentiment Indicator - **Latest State**: CSI 300 index is in a sentiment boom zone as of July 31, 2025 [20] 3. Leverage Ratios - **Top Stocks by Relaxed Leverage Ratio**: - Example: Dizhiyiyao-U (64.10%), Shenzhouxibao (64.06%), Zhongyida (59.68%) [45] 4. Financial Cost Burden Ratio - **Top Stocks by Financial Cost Burden**: - Example: Liaoning Chengda (241084.42), Yinbaoshanxin (2314.41), Ashichuang (69.43) [49]
