新华财经柏林7月30日电（记者车云龙张毅荣）德国联邦统计局30日公布的初步数据显示，经价格、季 节和工作日调整后，今年第二季度德国国内生产总值环比下降0.1%。第一季度德国经济环比增长 0.3%。 德国联邦统计局当天发布公报说，继年初经济回暖后，德国经济增长动能有所减弱。数据显示，第二季 度投资环比下降，私人和公共消费支出则有所增长。 德国经济研究所当天发表声明说，德国经济复苏虽有所放缓，但整体进程尚未中断，近期工业产出和商 业景气指数等指标表现积极。声明同时指出，欧盟与美国日前就关税达成的新贸易协议，将进一步加重 德国经济负担。 荷兰国际集团宏观研究主管卡斯滕·布热斯基表示，若美国对欧盟征收15%关税，预计将拖累德国经济 0.1至0.2个百分点。 2023年和2024年，德国经济分别萎缩0.3%和0.2%。受美国贸易政策影响，德国出口面临压力，联邦政 府此前将2025年经济增长预期下调至零增长。近期，德国多家主要经济研究机构预测，在基础设施基金 等财政刺激措施带动下，德国经济今年有望实现0.3%左右的增长。 （文章来源：新华社） ...

Quantitative Models and Construction Methods - **Model Name**: Broad-based Index Rotation Strategy **Model Construction Idea**: The strategy is based on the weekly change rate of the "total heat" indicator for broad-based indices. It selects the index with the highest heat change rate for investment, while staying out of the market if the "Other" group has the highest rate[7][13][16] **Model Construction Process**: 1. Calculate the weekly heat change rate for each broad-based index (CSI 300, CSI 500, CSI 1000, CSI 2000, and "Other"). 2. Smooth the weekly change rate using a 2-period moving average (MA2). 3. On the last trading day of each week, invest in the index with the highest MA2 heat change rate. If the "Other" group has the highest rate, remain in cash. **Model Evaluation**: The strategy demonstrates a clear logic of capturing short-term market sentiment shifts based on heat changes[13][16] - **Model Name**: Concept Heat TOP and BOTTOM Portfolios **Model Construction Idea**: This model identifies the hottest concepts each week and constructs two portfolios based on the highest and lowest heat stocks within these concepts[30][32][34] **Model Construction Process**: 1. Select the top 5 concepts with the largest weekly heat change rates. 2. Exclude the bottom 20% of stocks in terms of market capitalization within the selected concepts. 3. Construct the "TOP" portfolio by equally weighting the top 10 stocks with the highest total heat within each concept. 4. Construct the "BOTTOM" portfolio by equally weighting the bottom 10 stocks with the lowest total heat within each concept. **Model Evaluation**: The model effectively captures behavioral biases in concept-driven markets, where low-heat stocks in hot concepts tend to generate excess returns over time[30][32][34] --- Model Backtesting Results - **Broad-based Index Rotation Strategy**: - Annualized Return: 8.74% - Maximum Drawdown: 23.5% - 2025 YTD Return: 14.7%[16] - **Concept Heat BOTTOM Portfolio**: - Annualized Return: 15.71% - Maximum Drawdown: 28.89% - 2025 YTD Return: 25.5%[34] --- Quantitative Factors and Construction Methods - **Factor Name**: Total Heat Indicator **Factor Construction Idea**: The factor aggregates the browsing, watchlist, and click counts of individual stocks, normalized as a percentage of the total market, and scaled by 10,000[7] **Factor Construction Process**: 1. Aggregate the browsing, watchlist, and click counts for each stock. 2. Normalize the aggregated value as a percentage of the total market. 3. Multiply the normalized value by 10,000 to obtain the total heat score. The range of the indicator is [0, 10,000][7] **Factor Evaluation**: The factor serves as a proxy for market sentiment and attention, effectively capturing behavioral patterns such as overpricing or underreaction at the stock level[7] --- Factor Backtesting Results - **Total Heat Indicator**: - No specific backtesting results provided for this factor in isolation
