Quantitative Models and Construction Methods - **Model Name**: GAN_GRU **Model Construction Idea**: The GAN_GRU model combines Generative Adversarial Networks (GAN) for processing volume-price sequential features and Gated Recurrent Unit (GRU) for encoding sequential features to construct a stock selection factor [4][13] **Model Construction Process**: 1. **GRU Model**: - The GRU model is based on 18 volume-price features, including closing price, opening price, trading volume, turnover rate, etc. [14][17][19] - Training data includes the past 400 days of volume-price features for all stocks, with feature sampling every 5 trading days. The feature sampling shape is 40x18, using the past 40 days' features to predict the cumulative return over the next 20 trading days [18] - Data processing includes outlier removal and standardization for each feature in the time series and cross-sectional standardization at the stock level [18] - The model structure includes two GRU layers (GRU(128, 128)) followed by an MLP (256, 64, 64). The final output, predicted return (pRet), is used as the stock selection factor [22] - Training is conducted semi-annually, with training points on June 30 and December 31 each year. The training set and validation set are split in an 80:20 ratio [18] - Hyperparameters: batch_size equals the number of cross-sectional stocks, optimizer is Adam, learning rate is 1e-4, loss function is IC, early stopping rounds are 10, and maximum training rounds are 50 [18] 2. **GAN Model**: - The GAN model 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 \(z\) represents random noise, \(G(z)\) is the generated data, and \(D(G(z))\) is the discriminator's output probability for the generated data [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] - The generator uses an LSTM model to retain the sequential nature of input features, while the discriminator employs a CNN model to process the two-dimensional volume-price sequential features [33][37] **Model Evaluation**: The GAN_GRU model effectively captures volume-price sequential features and demonstrates strong predictive power for stock selection [4][13][22] Model Backtesting Results - **GAN_GRU Model**: - IC Mean: 0.1131*** - ICIR (non-annualized): 0.90 - Turnover Rate: 0.83 - Recent IC: 0.1241*** - One-Year IC Mean: 0.0867*** - Annualized Return: 37.52% - Annualized Volatility: 23.52% - IR: 1.59 - Maximum Drawdown: 27.29% - Annualized Excess Return: 23.14% [4][41][42] Quantitative Factors and Construction Methods - **Factor Name**: GAN_GRU Factor **Factor Construction Idea**: The GAN_GRU factor is derived from the GAN_GRU model, leveraging GAN for volume-price sequential feature processing and GRU for sequential feature encoding [4][13] **Factor Construction Process**: - The factor is constructed using the predicted return (pRet) output from the GAN_GRU model. The factor undergoes industry and market capitalization neutralization, as well as standardization [22] **Factor Evaluation**: The GAN_GRU factor demonstrates robust performance across various industries and time periods, with significant IC values and excess returns [4][13][41] Factor Backtesting Results - **GAN_GRU Factor**: - IC Mean: 0.1131*** - ICIR (non-annualized): 0.90 - Turnover Rate: 0.83 - Recent IC: 0.1241*** - One-Year IC Mean: 0.0867*** - Annualized Return: 37.52% - Annualized Volatility: 23.52% - IR: 1.59 - Maximum Drawdown: 27.29% - Annualized Excess Return: 23.14% [4][41][42] Industry-Specific Performance - **Recent IC Rankings (Top 5 Industries)**: - Social Services: 0.2198*** - Real Estate: 0.2027*** - Steel: 0.1774*** - Non-Bank Financials: 0.1754*** - Coal: 0.1537*** [4][41][42] - **One-Year IC Mean Rankings (Top 5 Industries)**: - Non-Bank Financials: 0.1401*** - Steel: 0.1367*** - Retail: 0.1152*** - Textiles & Apparel: 0.1124*** - Utilities: 0.1092*** [4][41][42] - **Recent Excess Return Rankings (Top 5 Industries)**: - Environmental Protection: 7.24% - Machinery: 4.37% - Real Estate: 4.03% - Textiles & Apparel: 3.89% - Building Materials: 2.91% [4][45][46] - **One-Year Average Excess Return Rankings (Top 5 Industries)**: - Building Materials: 2.15% - Real Estate: 1.97% - Social Services: 1.77% - Textiles & Apparel: 1.71% - Retail: 1.62% [4][45][46]

- The report discusses the macroeconomic recovery in China, highlighting the transition from "weak recovery" to "marginal improvement" as a key phase for economic activity and liquidity structure, which lays the foundation for subsequent profitability recovery and market style shifts towards dividends and low valuation assets [11][16][17] - A macro scoring model is referenced, indicating that the macroeconomic environment has been in a neutral to slightly pessimistic range in 2025, with the latest score (September 2025) being 7, reflecting a neutral to slightly optimistic outlook [13][14] - Dividend strategies (high dividend yield strategies) are emphasized as a classic value investment method, with their core logic analyzed from three dimensions: investor behavior, corporate operating characteristics, and market valuation systems. The dividend yield is identified as the core metric for evaluating dividend strategies [21][23] - The report highlights the strategic allocation value of dividend assets, emphasizing their long-term stable return characteristics and risk diversification functions, making them suitable as a "ballast" in investment portfolios, especially in a low-interest-rate environment [21][23][25] - The report introduces the "stability value + growth premium" logic for the power and power grid sectors, emphasizing their stable cash flow, regulatory framework ("permitted cost + reasonable return"), and policy support for energy transition and power security [26] - The report provides valuation metrics for high dividend yield-related ETF products tracking indices as of October 20, 2025. For example, the PE ratios for the National New Hong Kong Stock Connect Central Enterprise Dividend Index, Smart High Dividend Index, CSI Dividend Index, and CSI All Power Index are 8.88, 8.73, 8.29, and 17.60, respectively, with corresponding PB ratios of 0.85, 1.11, 0.80, and 1.76 [27][30] - The cyclical sector investment direction is analyzed, with key drivers identified as domestic demand policies and global demand recovery. Non-bank financials and consumer sectors benefit from dual drivers, while financial real estate and infrastructure are supported by domestic policies, and materials benefit from global restocking [40][42][47] - Valuation metrics for cyclical-related ETF products tracking indices are provided as of October 20, 2025. For example, the PE ratios for the Hong Kong Stock Connect Non-Bank, Financial Real Estate, 800 Consumer, All Materials, and Infrastructure Engineering indices are 9.44, 9.10, 19.20, 26.90, and 8.51, respectively, with corresponding PB ratios of 1.13, 0.86, 4.36, 2.10, and 0.72 [51][55] - The report emphasizes the role of broad-based assets like the SSE 50 ETF and CSI 300 ETF as core holdings in portfolios, supported by policy efforts to stabilize the market and attract long-term funds, as well as their low historical valuations and high safety margins [64][65][66] - Valuation metrics for broad-based ETF products tracking indices are provided as of October 20, 2025. For example, the PE ratios for the SSE 50 and CSI 300 indices are 11.99 and 14.22, respectively, with corresponding PB ratios of 1.30 and 1.48. Both indices are near the 68th percentile of their five-year PB range [69][70][71]
