Quantitative Models and Construction 1. Model Name: DecompGRU-based Multi-Stock Long Portfolio - **Model Construction Idea**: The model is based on the DecompGRU architecture, which integrates trend decomposition with end-to-end time-series and cross-sectional modeling for stock scoring[8] - **Model Construction Process**: - Select the top 200 stocks with the highest integrated scores from the DecompGRU model - Equally weight the selected stocks in the portfolio - Rebalance weekly on the first trading day of the week based on updated factor values from the previous Friday's close - Exclude stocks that are limit-up, limit-down, or suspended from trading - The stock selection universe is the CSI All Share Index - No transaction costs are considered - Benchmark: CSI All Share Equal Weight Index[8] - **Model Evaluation**: The model demonstrates strong performance in terms of cumulative returns and risk-adjusted metrics[10] 2. Model Name: DecompGRU-based ETF Rotation Portfolio - **Model Construction Idea**: The model aggregates individual stock scores from the DecompGRU model to construct an ETF rotation strategy[11] - **Model Construction Process**: - ETF pool includes industry and thematic ETFs - Retain only the ETF with the highest 5-day average trading volume if multiple ETFs track the same index - ETFs must meet liquidity criteria: 5-day average daily turnover > 20 million CNY and 20-day average daily turnover > 10 million CNY - Weekly rebalancing with 2-6 ETFs in the portfolio - Benchmark: Wind Thematic ETF Index[11] - **Model Evaluation**: The model shows robust cumulative returns and moderate drawdowns, indicating its effectiveness in capturing ETF-level opportunities[13] --- Model Backtesting Results 1.
