Quantitative Models and Construction - **Model Name**: DecompGRU **Model Construction Idea**: The model improves information interaction between time-series and cross-sectional data by introducing two simple de-mean modules on the GRU baseline model[18] **Model Construction Process**: 1. The DecompGRU model architecture is based on GRU as the baseline 2. Two de-mean modules are added to enhance the interaction between time-series and cross-sectional data 3. The model is trained using IC and weighted MSE loss functions[18] **Model Evaluation**: The model demonstrates improved interaction between time-series and cross-sectional data, enhancing prediction accuracy[18] Model Backtesting Results - **DecompGRU TOP200 Portfolio**: - Cumulative absolute return: 41.11% - Excess return relative to WIND All A equal-weight index: 13.98% - Maximum drawdown: 10.08% - Weekly win rate: 64.52% - Monthly win rate: 100% - October absolute return: 1.78%, excess return: -0.07%[11] - **ETF Rotation Portfolio**: - Cumulative absolute return: 19.06% - Excess return relative to benchmark: -2.00% - Maximum drawdown: 7.82% - Weekly win rate: 62.50% - Monthly win rate: 57.14% - October absolute return: -2.04%, excess return: -1.18%[14][15] Quantitative Factors and Construction - **Factor Name**: Sentiment Heat Factor **Factor Construction Idea**: The factor aggregates stock-level sentiment heat metrics (e.g., browsing, self-selection, and clicks) to represent broader market sentiment[19] **Factor Construction Process**: 1.
