Quantitative Models and Construction Methods 1. Model Name: Sentiment Model - **Model Construction Idea**: The sentiment model is designed to measure the strength of market sentiment using factors related to limit-up and limit-down stocks[14] - **Model Construction Process**: The model uses factors such as the proportion of net limit-up stocks, next-day returns of limit-down stocks, proportion of limit-up stocks, proportion of limit-down stocks, and high-frequency board-hitting returns. These factors are aggregated to calculate a sentiment score, with a maximum score of 5. The sentiment score for the current period is 0[14][18] - **Model Evaluation**: The sentiment model indicates that the market sentiment remains low, reflecting weak investor confidence[14][18] 2. Model Name: Moving Average Strength Index - **Model Construction Idea**: This model evaluates the strength of market trends by calculating the moving average strength index based on secondary industry indices[14] - **Model Construction Process**: The moving average strength index is calculated using the performance of secondary industry indices. The current market score is 181, which corresponds to the 62.50th percentile since 2023[14] - **Model Evaluation**: The index suggests that there is still significant room for downward movement in the market[14] 3. Model Name: High-Frequency Capital Flow Model - **Model Construction Idea**: This model uses high-frequency capital flow data to generate buy and sell signals for major broad-based indices[14] - **Model Construction Process**: The model tracks the capital flow trends of indices such as CSI 300, CSI 500, CSI 1000, and CSI 2000. The signals for all indices are currently negative, indicating a bearish outlook[14][18] - **Model Evaluation**: The model shows that all major broad-based indices have turned negative, reflecting weak market conditions[14][18] --- Model Backtesting Results 1. Sentiment Model - Sentiment score: 0 (out of 5)[14][18] 2. Moving Average Strength Index - Current score: 181 (62.50th percentile since 2023)[14] 3. High-Frequency Capital Flow Model - CSI 300: Negative signal - CSI 500: Negative signal - CSI 1000: Negative signal - CSI 2000: Negative signal[14][18] --- Quantitative Factors and Construction Methods 1. Factor Name: Factor Crowding Index - **Factor Construction Idea**: The factor crowding index measures the degree of crowding in specific factors, which can serve as a warning for factor inefficiency[19] - **Factor Construction Process**: The index is calculated using four metrics: valuation spread, pairwise correlation, long-term return reversal, and factor volatility. The composite score is derived from these metrics. For example, the crowding scores for small-cap, low-valuation, high-profitability, and high-growth factors are 0.06, -0.31, -0.01, and 0.28, respectively[19][20] - **Factor Evaluation**: The crowding index provides insights into the potential inefficiency of factors due to excessive capital allocation[19] --- Factor Backtesting Results 1. Factor Crowding Index - Small-cap factor crowding score: 0.06 - Low-valuation factor crowding score: -0.31 - High-profitability factor crowding score: -0.01 - High-growth factor crowding score: 0.28[19][20]

量化择时系列研究之一:基于稀疏自编码器的指数择时模型
Hua Yuan Zheng Quan· 2026-02-02 09:17
Quantitative Models and Construction Methods - **Model Name**: Sparse Auto Encoder (SAE) **Model Construction Idea**: The model aims to compress high-dimensional features into low-dimensional sparse coding while ensuring the reconstructed features retain most of the original information. It also incorporates autoregressive loss and sparsity penalties to enhance robustness and reduce overfitting [7][8][9] **Model Construction Process**: 1. **Encoding**: Compress input features into sparse coding $ \text{code}_{i}=\text{Encoder}(x_{i}) $ Here, $ x_{i} $ represents input features, and $ \text{code}_{i} $ is the compressed sparse coding [8] 2. **Decoding**: Reconstruct features from sparse coding $ \hat{x}_{i}=\text{Decoder}(code_{i}) $ $ \hat{x}_{i} $ represents reconstructed features, which should closely resemble $ x_{i} $ [8] 3. **Prediction**: Predict future index returns using hidden layer features $ \hat{y}_{i}=\text{Predictor}(res_{i}) $ $ \hat{y}_{i} $ represents the predicted future returns [8] 4. **Loss Function**: Combines prediction error, reconstruction error, and sparsity penalty $$ Loss=\frac{1}{N}\sum\nolimits_{i=1}^{N}\left(\mathcal{J}(y_{i},{\hat{y}}_{i})+\lambda_{1}\mathcal{L}\left(x_{i},{\hat{x}}_{i}\right)+\lambda_{2}SparseLoss(code_{i})\right) $$ $ \mathcal{J} $ measures prediction error, $ \mathcal{L} $ measures reconstruction error, and $ SparseLoss $ applies sparsity penalties using KL divergence or vector norms [9][12] **Evaluation**: The model effectively selects features, enhances robustness, and learns the "true" patterns of index movements [11] - **Wavelet Transform for Noise Reduction** **Construction Idea**: Decompose time-series data into multiple components to isolate noise and retain meaningful information [19][20] **Construction Process**: 1. Select parent wavelet $ \varphi $ and mother wavelet $ \psi $ $ \varphi_{jk}=2^{-j/2}\varphi(2^{-j}-k) $ $ \psi_{jk}=2^{-j/2}\psi(2^{-j}-k) $ Parent wavelet captures low-frequency trends, while mother wavelet captures high-frequency fluctuations [19][20] 2. Reconstruct time-series data using wavelet coefficients $$ x(t)=\sum\nolimits_{k}s_{j,k}\varphi_{j,k}+\sum\nolimits_{k}d_{j,k}\psi_{j,k}+\ldots+\sum\nolimits_{k}d_{1,k}\psi_{1,k} $$ Coefficients $ S_{J,k} $ and $ d_{j,k} $ are calculated as: $ S_{J,k}=\int\varphi_{J,k}x(s)ds $ $ d_{j,k}=\int\psi_{J,k}x(s)ds $ [20] **Evaluation**: Reduces overfitting risks by filtering out noise and retaining meaningful components [21] Model Backtesting Results - **SAE Model** **Performance on CSI 500 Index**: - Multi-strategy annualized return: 43.86% - Long-only annualized return: 23.30% - Short-only annualized return: 16.68% - Sharpe ratio: 2.07 (multi-strategy), 1.39 (long-only), 1.28 (short-only) - Maximum drawdown: -14.00% (multi-strategy), -16.04% (long-only), -14.30% (short-only) [29][33][34] **Performance on CSI 1000 Index**: - Multi-strategy annualized return: 51.21% - Long-only annualized return: 26.00% - Short-only annualized return: 20.01% - Sharpe ratio: 1.41 (long-only), 1.27 (short-only) - Maximum drawdown: -22.08% (long-only), -19.85% (short-only) [43][46][47] **Performance on CSI 2000 Index**: - Multi-strategy annualized return: 32.40% - Long-only annualized return: 32.56% - Sharpe ratio: 1.62 (long-only) - Maximum drawdown: -25.59% (long-only) [55][56] **Performance on CSI All Share Index**: - Multi-strategy annualized return: 18.74% - Long-only annualized return: 18.83% - Sharpe ratio: 1.26 (long-only) - Maximum drawdown: -16.95% (long-only) [55][56] Quantitative Factors and Construction Methods - **Input Features** **Construction Idea**: Use common technical indicators and derived metrics from daily K-line data as model inputs [16][18] **Construction Process**: 1. **Technical Indicators**: - RSI: $ RSI=(N\text{-day absolute closing price increase})/(N\text{-day absolute closing price decrease}) $ - OBV: $ OBV=\text{sum of closing price change signs} \times \text{turnover rate} $ - MACD: $ DIF=12\text{-day EMA}-26\text{-day EMA} $ $ DEA=DIF\text{'s 9-day EMA} $ $ MACD=DIF-DEA $ [16][17] 2. **Derived Metrics**: Rolling averages, relative positions of moving averages, volatility metrics, and other derived indicators [16][18] **Evaluation**: The feature set is comprehensive but not optimized, as no additional filtering was applied to avoid overfitting [18] Factor Backtesting Results - **RSI, OBV, MACD** **Performance**: Incorporated into the SAE model, contributing to the overall strategy performance across indices [16][18] Key Observations - The SAE model performs better on smaller-cap indices like CSI 2000 and CSI 1000 compared to CSI 500, indicating its effectiveness in smaller market segments [62] - Multi-strategy returns are balanced between long and short positions, with no significant bias toward either direction [42][54] - The model's robustness and sparsity design mitigate overfitting risks and enhance generalization across different market conditions [11][21] - Setting appropriate thresholds for signal generation improves strategy stability and reduces transaction costs [66]
