1. Report Industry Investment Rating No information about the report industry investment rating is provided in the given content. 2. Core Viewpoints of the Report - The Middle - East situation and oil price shocks will continue to disrupt global risk appetite. A - share market is difficult to completely shake off external emotional suppression in the short term, and it is necessary to closely monitor the evolution of the Middle - East situation, international oil price trends, and the further transmission of external market fluctuations to A - share sentiment [8][15] - The inter - bank liquidity in the bond market is still relatively abundant. The central bank's open - market operations continue to send signals of care. Treasury bond futures are generally strong, with the long - end performing better, and the short - term bond market may maintain a strong and volatile pattern [11][15] - The core logic of the commodity market is the parallel evolution of geopolitical risk premium and domestic fundamental repair. Precious metals are strong due to the Middle - East situation and macro - expectation repricing, while industrial metals such as tin benefit from the marginal recovery of manufacturing prosperity. The commodity market may still have a structural market in the short term [9][15] 3.

Quantitative Models and Construction GAN_GRU Model - **Model Name**: GAN_GRU - **Construction Idea**: The GAN_GRU model combines Generative Adversarial Networks (GAN) for feature generation and Gated Recurrent Units (GRU) for time-series feature encoding to create a stock selection factor[4][13][22] - **Construction Process**: 1. **GAN Component**: - **Generator**: Generates realistic data samples from random noise using the loss function: $$L_{G}\,=\,-\mathbb{E}_{z\sim P_{z}(z)}[\log(D(G(z)))]$$ where \(z\) represents random noise, \(G(z)\) is the generated data, and \(D(G(z))\) is the discriminator's output probability that the generated data is real[24][25][26] - **Discriminator**: Distinguishes real data from generated data using the loss function: $$L_{D}=-\mathbb{E}_{x\sim P_{data}(x)}[\log\!D(x)]-\mathbb{E}_{z\sim P_{z}(z)}[\log(1-D(G(z)))]$$ where \(x\) is real data, \(D(x)\) is the discriminator's output probability for real data, and \(D(G(z))\) is the output probability for generated data[27][29][30] - **Training Process**: Alternating training of the generator and discriminator until convergence[30][34] 2. **GRU Component**: - Two GRU layers (GRU(128,128)) followed by an MLP (256,64,64) to encode time-series features and predict future returns[22] - Input features include 18 price-volume metrics (e.g., closing price, turnover rate) sampled over 40 days to predict cumulative returns for the next 20 trading days[14][18][19] - Data preprocessing involves outlier removal, normalization, and cross-sectional standardization[18] - Training uses semi-annual rolling windows with hyperparameters such as batch size equal to the number of stocks, Adam optimizer, learning rate of \(1e-4\), and IC-based loss function[18][22] 3. **Feature Generation**: - GAN's generator processes raw price-volume time-series features (Input_Shape=(40,18)) and outputs transformed features with preserved time-series properties[37] - **Evaluation**: The model effectively combines GAN's feature generation capabilities with GRU's time-series encoding, providing robust predictive power for stock selection[4][22][37] --- Model Backtesting Results GAN_GRU Model Performance Metrics -
