Quantitative Models and Construction Methods - **Model Name**: A-Share Industry Rotation Model **Model Construction Idea**: The model uses six factors—capital, valuation, sentiment, momentum, overbought/oversold, and profitability—to build a scoring system for industry evaluation[17] **Model Construction Process**: - **Capital Factor**: Based on industry net inflow rate of major funds - **Valuation Factor**: Uses the valuation percentile of the industry over the past year - **Sentiment Factor**: Derived from the proportion of rising constituent stocks - **Momentum Factor**: Based on MACD indicator - **Overbought/Oversold Factor**: Uses RSI indicator - **Profitability Factor**: Based on the consensus forecast EPS percentile of the industry over the past year[17] **Model Evaluation**: The model provides a comprehensive scoring system to assess industry rotation trends[17] - **Model Name**: Consensus Stock Selection Model **Model Construction Idea**: The model identifies high-growth industries and selects stocks with high similarity between high-frequency capital flow trends and stock price trends[20] **Model Construction Process**: - Filters high-growth industries at the Shenwan secondary industry level based on the past 30-day performance - Calculates momentum, valuation, and frequency of price increases for stocks within these industries - Uses high-frequency minute-level capital flow data to compute changes in inflow/outflow for each stock - Selects stocks with the highest similarity between capital flow trends and price trends within the top-performing secondary industries[20] **Model Evaluation**: The model effectively identifies stocks with strong capital flow and price trend alignment[20] --- Model Backtesting Results - **A-Share Industry Rotation Model**: - **Top Scoring Industries**: Comprehensive (+10), Non-ferrous Metals (+10), Electronics (+7)[18][19] - **Low Scoring Industries**: Banking (-15), Petrochemicals (-9), Transportation (-8)[19] - **Consensus Stock Selection Model**: - **Selected Industries**: Communication Equipment, Ground Armament II, Components[21] - **Selected Stocks**: - Communication Equipment: New Yisheng, Move Communication, Feiling Kesi, Hengtong Optoelectronics, Meixin Technology - Ground Armament II: Great Wall Military Industry, Optical Shares, Inner Mongolia First Machine, Sweet Qin Equipment, Ganfa Technology - Components: Jingwang Electronics, Deep South Circuit, Fangbang Shares, Zhongjing Electronics, Shenghong Technology[21] --- Quantitative Factors and Construction Methods - **Factor Name**: Capital Factor **Construction Idea**: Measures industry net inflow rate of major funds[17] **Construction Process**: Aggregates daily net inflow data for transactions exceeding 10,000 shares or 200,000 yuan[12] **Evaluation**: Reflects the strength of capital flow within industries[17] - **Factor Name**: Valuation Factor **Construction Idea**: Uses industry valuation percentile over the past year[17] **Construction Process**: Calculates the relative valuation position of the industry within a one-year window[17] **Evaluation**: Indicates whether an industry is undervalued or overvalued[17] - **Factor Name**: Sentiment Factor **Construction Idea**: Based on the proportion of rising constituent stocks[17] **Construction Process**: Computes the percentage of stocks within the industry that have increased in price[17] **Evaluation**: Captures market sentiment towards the industry[17] - **Factor Name**: Momentum Factor **Construction Idea**: Uses MACD indicator to measure price trends[17] **Construction Process**: Applies MACD calculations to industry-level data[17] **Evaluation**: Identifies industries with strong upward or downward trends[17] - **Factor Name**: Overbought/Oversold Factor **Construction Idea**: Uses RSI indicator to assess market conditions[17] **Construction Process**: Calculates RSI values for industries to determine overbought or oversold conditions[17] **Evaluation**: Helps identify potential reversals in industry trends[17] - **Factor Name**: Profitability Factor **Construction Idea**: Based on consensus forecast EPS percentile over the past year[17] **Construction Process**: Aggregates EPS forecasts and calculates relative percentile rankings[17] **Evaluation**: Reflects the earnings potential of industries[17] --- Factor Backtesting Results -
