Quantitative Models and Construction Methods 1. Model Name: Industry Crowdedness Monitoring Model - **Model Construction Idea**: This model is designed to monitor the crowdedness levels of Shenwan First-Level Industry Indices on a daily basis, identifying industries with high or low crowdedness levels to provide insights for potential investment opportunities[3] - **Model Construction Process**: The model calculates the crowdedness levels of various industries based on daily data. It identifies industries with significant changes in crowdedness levels and tracks the inflow and outflow of major funds in these industries. For example, on the previous trading day, industries such as non-ferrous metals, electrical equipment, and electronics had high crowdedness levels, while food and beverage, as well as beauty care, exhibited lower levels[3] - **Model Evaluation**: The model provides a useful tool for identifying industry trends and fund flow dynamics, which can help investors make informed decisions[3] 2. Model Name: Premium Rate Z-Score Model - **Model Construction Idea**: This model is used to screen ETF products with potential arbitrage opportunities by calculating the Z-score of their premium rates over a rolling window[4] - **Model Construction Process**: The model involves the following steps: 1. Calculate the premium rate of an ETF product as the percentage difference between its market price and its net asset value (NAV) 2. Compute the Z-score of the premium rate over a rolling window to identify deviations from the mean 3. Highlight ETF products with significant Z-scores as potential arbitrage opportunities while also flagging the risk of price corrections[4] - **Model Evaluation**: The model effectively identifies ETFs with potential mispricing, offering opportunities for arbitrage while cautioning about associated risks[4] --- Backtesting Results of Models 1. Industry Crowdedness Monitoring Model - **Key Observations**: - Non-ferrous metals, electrical equipment, and electronics had the highest crowdedness levels on the previous trading day[3] - Food and beverage, as well as beauty care, exhibited the lowest crowdedness levels[3] - Significant changes in crowdedness were observed in the automotive and light industry sectors[3] 2.
