Quantitative Models and Construction Methods 1. Model Name: Industry Crowding Monitoring Model - **Model Construction Idea**: This model is designed to monitor the crowding levels of Shenwan First-Level Industry Indices on a daily basis, identifying industries with high or low crowding levels to provide insights for potential investment opportunities[3] - **Model Construction Process**: The model calculates the crowding levels of various industries based on daily data. It identifies industries with the highest crowding levels (e.g., non-ferrous metals, electronics, and communication) and those with the lowest levels (e.g., media, coal, and petrochemicals). Additionally, it tracks significant changes in crowding levels for specific industries (e.g., food and beverage, comprehensive, and non-bank financials)[3] - **Model Evaluation**: The model provides a systematic approach to assess industry crowding dynamics, offering valuable insights for sector allocation strategies[3] 2. Model Name: Premium Rate Z-Score Model - **Model Construction Idea**: This model is used to screen ETF products for potential arbitrage opportunities by calculating the Z-score of premium rates on a rolling basis[4] - **Model Construction Process**: The model involves the following steps: 1. Calculate the premium rate of an ETF product 2. Compute the Z-score of the premium rate over a rolling window 3. Identify ETFs with significant deviations in Z-scores, which may indicate potential arbitrage opportunities or risks of price corrections[4] - **Model Evaluation**: The model effectively identifies ETFs with potential mispricing, aiding in arbitrage decision-making[4] --- Model Backtesting Results 1. Industry Crowding Monitoring Model - **Top Crowded Industries**: Non-ferrous metals, electronics, and communication were identified as the most crowded industries on the previous trading day[3] - **Least Crowded Industries**: Media, coal, and petrochemicals exhibited the lowest crowding levels[3] - **Significant Changes**: Food and beverage, comprehensive, and non-bank financials showed notable variations in crowding levels[3] 2. Premium Rate Z-Score Model - **Arbitrage Signals**: The model flagged ETFs with significant Z-score deviations, suggesting potential arbitrage opportunities. Specific ETFs and their corresponding signals were not detailed in the report[4] --- Quantitative Factors and Construction Methods No specific quantitative factors were explicitly mentioned or constructed in the report. The focus was primarily on the models described above.
