Quantitative Models and Factor Analysis Quantitative Models and Construction - **Model Name**: CSI 500 Enhanced Portfolio **Model Construction Idea**: The model aims to generate excess returns relative to the CSI 500 index by leveraging quantitative strategies and factor-based stock selection[53][55] **Model Construction Process**: 1. The model uses a strategy-driven approach to select stocks within the CSI 500 universe 2. Portfolio weights are optimized based on factor exposures and risk constraints 3. The portfolio is rebalanced periodically to maintain alignment with the strategy[54][56] **Model Evaluation**: The model has demonstrated significant long-term excess returns but underperformed the benchmark in the most recent week[53][55] - **Model Name**: CSI 300 Enhanced Portfolio **Model Construction Idea**: Similar to the CSI 500 Enhanced Portfolio, this model seeks to outperform the CSI 300 index through quantitative factor-based strategies[57][59] **Model Construction Process**: 1. Stocks are selected from the CSI 300 universe based on factor signals 2. Portfolio optimization is performed to balance factor exposures and minimize risk 3. Regular rebalancing ensures the portfolio remains aligned with the strategy[59][60] **Model Evaluation**: The model has achieved consistent long-term excess returns but slightly underperformed the benchmark in the most recent week[57][59] Model Backtesting Results - **CSI 500 Enhanced Portfolio**: - Weekly return: 2.92% - Underperformance relative to benchmark: -0.96% - Cumulative excess return since 2020: 50.58% - Maximum drawdown: -4.99%[53][55] - **CSI 300 Enhanced Portfolio**: - Weekly return: 2.28% - Underperformance relative to benchmark: -0.09% - Cumulative excess return since 2020: 35.61% - Maximum drawdown: -5.86%[57][59] --- Quantitative Factors and Construction - **Factor Name**: Beta Factor **Factor Construction Idea**: Measures the sensitivity of a stock's returns to market movements, with high-beta stocks expected to outperform in bullish markets[62][63] **Factor Construction Process**: 1. Beta is calculated using historical regression of stock returns against market returns 2. Stocks are ranked based on their beta values, and portfolios are constructed to maximize exposure to high-beta stocks[62][63] **Factor Evaluation**: Beta factor exhibited strong positive excess returns during the week, indicating market preference for high-beta stocks[63][66] - **Factor Name**: Value Factor **Factor Construction Idea**: Represents stocks with low valuation metrics, such as price-to-book or price-to-earnings ratios, which are expected to outperform over the long term[62][63] **Factor Construction Process**: 1. Stocks are ranked based on valuation metrics like book-to-price (BTOP) 2. Portfolios are constructed to overweight undervalued stocks[62][63] **Factor Evaluation**: Value factor showed significant negative excess returns during the week, reflecting weak market sentiment toward value stocks[63][66] Factor Backtesting Results - **Beta Factor**: - Weekly excess return: Positive[63][66] - **Value Factor**: - Weekly excess return: Negative[63][66] --- Composite Factor Analysis - **Factor Name**: Liquidity Factor **Factor Construction Idea**: Captures the ease of trading a stock, with higher liquidity stocks expected to perform better in volatile markets[62][63] **Factor Construction Process**: 1. Liquidity is measured using metrics like average daily turnover 2. Stocks are ranked, and portfolios are constructed to overweight high-liquidity stocks[62][63] **Factor Evaluation**: Liquidity factor demonstrated positive correlation with Beta and Momentum factors, indicating a preference for liquid, high-momentum stocks during the week[63][64] - **Factor Name**: Momentum Factor **Factor Construction Idea**: Represents stocks with strong recent performance, which are expected to continue outperforming in the short term[62][63] **Factor Construction Process**: 1. Momentum is calculated based on trailing returns over a specific period 2. Stocks are ranked, and portfolios are constructed to overweight high-momentum stocks[62][63] **Factor Evaluation**: Momentum factor showed positive performance, aligning with market trends favoring high-momentum stocks[63][66] Composite Factor Backtesting Results - **Liquidity Factor**: - Weekly correlation with Beta: Positive[63][64] - **Momentum Factor**: - Weekly excess return: Positive[63][66]

证券研究报告 | 金融工程 gszqdatemark 2025 06 22 年 月 日 量化周报 市场仍处于日线级别上涨中 市场仍处于日线级别上涨中。本周（6.16-6.20），大盘震荡下行，上证指 数全周收跌 0.51%。在此背景下，非银确认日线级别上涨，汽车、新能源 迎来日线级别下跌。当下，我们认为市场再次回到 4 月 7 日低点的概率基 本不存在了。由于上证指数、上证 50、中证 500、中证 1000 仍处于日线 级别上涨中，且还有部分指数和板块没有确认日线上涨，因此，我们认为 市场的日线级别上涨还要持续一段时间，后续市场有望继续上涨。中期来 看，上证指数、上证 50、沪深 300、中证 500、深证成指、创业板指、科 创 50 纷纷确认周线级别上涨，而且在日线上只走出了 1-3 浪结构，中期 牛市刚刚开始；此外，已有 20 个行业处于周线级别上涨中，且 7 个行业 周线上涨只走了 1 浪结构，因此我们认为本轮牛市刚刚开始，而且还是个 普涨格局。中期对于投资者而言，仍然可以逆势布局。 A 股景气指数观察。截至 2025 年 6 月 20 日，A 股景气指数为 20.94，相 比 2023 年底上升 1 ...
