Quantitative Models and Construction Methods 1. Model Name: Timing System Signal - Model Construction Idea: The model uses the distance between the short-term and long-term moving averages of the WIND All A Index to determine market trends and timing signals [2][7][13] - Model Construction Process: 1. Define the short-term moving average (20-day) and long-term moving average (120-day) of the WIND All A Index 2. Calculate the distance between the two moving averages: $ Distance = \frac{Short\text{-}term\ MA - Long\text{-}term\ MA}{Long\text{-}term\ MA} $ 3. If the absolute value of the distance is greater than 3%, it indicates a significant trend signal [2][7][13] - Model Evaluation: The model effectively identifies market trends and provides actionable timing signals [2][7][13] 2. Model Name: Industry Trend Allocation Model - Model Construction Idea: This model identifies industry allocation opportunities based on medium-term reversal expectations and performance trends [6][8][15] - Model Construction Process: 1. Monitor medium-term reversal signals for specific industries, such as the real estate chain 2. Use performance trend analysis to identify industries with strong growth potential, such as technology, semiconductors, and chemicals 3. Recommend ETF products corresponding to these industries for allocation [6][8][15] - Model Evaluation: The model provides clear industry allocation guidance and captures sectoral opportunities effectively [6][8][15] 3. Model Name: Position Management Model - Model Construction Idea: This model determines the recommended equity allocation ratio based on valuation levels and market trends [9] - Model Construction Process: 1. Assess the PE and PB valuation levels of the WIND All A Index 2. Combine valuation levels with short-term market trends to determine the recommended equity allocation ratio 3. For example, with the current PE at the 90th percentile and PB at the 50th percentile, the model suggests an 80% equity allocation [9] - Model Evaluation: The model provides a systematic approach to position management, balancing valuation and trend considerations [9] --- Model Backtesting Results 1. Timing System Signal - Moving average distance: 6.28% (absolute value > 3%) - Market trend line: 6812 points - Profitability effect: 1.91% (significantly > 0) [2][7][13] 2. Industry Trend Allocation Model - Recommended sectors: - Real estate chain (e.g., Building Materials ETF: 159745.SZ) - Technology (e.g., Satellite ETF: 563230.SH) - Semiconductors and communication (e.g., Semiconductor Equipment ETF: 159516.SZ, Communication ETF: 515880.SH) - Metals and chemicals (e.g., Industrial Metals ETF: 560860.SH, Rare Earth ETF: 516150.SH, Chemical ETF: 159870.SZ) [6][8][15] 3. Position Management Model - Recommended equity allocation: 80% [9] --- Quantitative Factors and Construction Methods 1. Factor Name: Profitability Effect - Factor Construction Idea: Measures the market's profitability to assess upward momentum [2][7][13] - Factor Construction Process: 1. Calculate the profitability effect as a percentage of profitable stocks in the market 2. A positive profitability effect indicates upward momentum [2][7][13] - Factor Evaluation: The factor effectively captures market sentiment and momentum [2][7][13] --- Factor Backtesting Results 1. Profitability Effect - Current value: 1.91% (significantly > 0) [2][7][13]
