Quantitative Models and Construction Methods 1. Model Name: GAN_GRU Model - **Model Construction Idea**: The GAN_GRU model combines Generative Adversarial Networks (GAN) for feature generation and Gated Recurrent Unit (GRU) for time-series feature encoding to create a stock selection factor[4][13][14] - **Model Construction Process**: - **GAN Component**: - The GAN consists of a generator (G) and a discriminator (D). The generator learns the real data distribution and generates realistic samples, while the discriminator distinguishes between real and generated data[23][24] - Generator loss function: $$L_{G} = -\mathbb{E}_{z\sim P_{z}(z)}[\log(D(G(z)))]$$ where \(z\) is random noise, \(G(z)\) is the generated data, and \(D(G(z))\) is the discriminator's output probability for generated data being real[24][25] - Discriminator 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 discriminator's output probability for generated data[27][29] - GAN training alternates between updating the generator and discriminator parameters through backpropagation[30] - The generator uses an LSTM model to preserve the sequential nature of input features, while the discriminator employs a CNN model to process the 2D structure of the generated features[33][37] - **GRU Component**: - Two GRU layers (GRU(128, 128)) are used, followed by an MLP (256, 64, 64) to output predicted returns (\(pRet\)) as the stock selection factor[22] - Input features include 18 price-volume characteristics (e.g., closing price, turnover rate) sampled over the past 40 days to predict cumulative returns for the next 20 trading days[14][18] - Data preprocessing includes outlier removal, standardization, and cross-sectional normalization[18] - Training is conducted semi-annually with rolling updates, using Adam optimizer, a learning rate of \(1e-4\), and IC as the loss function[18] - **Model Evaluation**: The GAN_GRU model effectively integrates GAN's feature generation capabilities with GRU's time-series encoding, making it suitable for capturing complex price-volume patterns in stock selection[4][13] --- Model Backtesting Results GAN_GRU Model - **IC Mean**: 0.1096*** (2019.02–2026.02)[41] - **ICIR (Non-Annualized)**: 0.87[42] - **Turnover Rate**: 0.82X[42] - **Recent IC**: -0.0105*** (latest period)[41][42] - **1-Year IC Mean**: 0.0517***[41][42] - **Annualized Return**: 38.13%[42] - **Annualized Volatility**: 23.18%[42] - **IR**: 1.64[42] - **Maximum Drawdown**: 27.29%[42] - **Annualized Excess Return**: 22.32%[41][42]
