Quantitative Models and Construction Methods 1. Model Name: Broad-based Index Rotation Strategy - **Model Construction Idea**: The strategy is based on the marginal changes in the "heat" (attention) of broad-based indices. By identifying the index with the highest weekly heat change rate, the strategy rotates into that index. If the "Other" group (stocks not included in the four main indices) has the highest heat change rate, the strategy remains in cash[7][13]. - **Model Construction Process**: 1. Calculate the weekly heat change rate for the components of four major indices (CSI 300, CSI 500, CSI 1000, CSI 2000) and the "Other" group. 2. Smooth the weekly heat change rate using a 2-week moving average (MA2). 3. At the end 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[13][16]. - **Model Evaluation**: The strategy demonstrates a clear logic of leveraging market sentiment shifts to generate returns[13]. --- Model Backtesting Results 1. Broad-based Index Rotation Strategy - **Annualized Return**: 8.74% since 2017[16] - **Maximum Drawdown**: 23.5%[16] - **2025 YTD Return**: 20.9%[16] --- Quantitative Factors and Construction Methods 1. Factor Name: Total Heat Indicator - **Factor Construction Idea**: The total heat indicator aggregates the attention metrics (e.g., browsing, watchlist additions, and clicks) of individual stocks. It is normalized as a percentage of the total market and scaled by 10,000. This indicator serves as a proxy for market sentiment[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 indicator, with a range of [0, 10,000][7]. - **Factor Evaluation**: The factor effectively captures market sentiment and can be used to identify mispricing due to overreaction or underreaction[7]. 2. Factor Name: Weekly Heat Change Rate (MA2) - **Factor Construction Idea**: This factor measures the weekly change in the total heat indicator, smoothed using a 2-week moving average. It reflects short-term sentiment dynamics[13][20]. - **Factor Construction Process**: 1. Calculate the weekly change rate of the total heat indicator for each stock. 2. Smooth the weekly change rate using a 2-week moving average (MA2)[13][20]. - **Factor Evaluation**: The factor is useful for identifying short-term sentiment-driven opportunities in broad-based indices, industries, and concepts[13][20]. 3. Factor Name: Concept Heat Ranking - **Factor Construction Idea**: This factor ranks concepts based on their weekly heat change rates. It identifies the top and bottom concepts for constructing portfolios[28][31]. - **Factor Construction Process**: 1. Rank concepts by their weekly heat change rates. 2. Select the top 5 concepts with the highest heat change rates. 3. Construct two portfolios: - **TOP Portfolio**: Select the top 10 stocks with the highest total heat within each of the top 5 concepts. - **BOTTOM Portfolio**: Select the bottom 10 stocks with the lowest total heat within each of the top 5 concepts[31]. - **Factor Evaluation**: The factor captures the behavioral tendencies of investors, leveraging the rapid price adjustments in high-attention stocks[28][31]. --- Factor Backtesting Results 1. Total Heat Indicator - **No specific backtesting results provided** 2. Weekly Heat Change Rate (MA2) - **No specific backtesting results provided** 3. Concept Heat Ranking - **BOTTOM Portfolio Annualized Return**: 15.71%[33] - **BOTTOM Portfolio Maximum Drawdown**: 28.89%[33] - **2025 YTD Return for BOTTOM Portfolio**: 29.2%[33]

一、事件及点评： 今年红利整体出现明显分化，上半年A股大部分红利资产跑输大盘，结构"缩圈"至银行板块。例如上半 年中证红利指数下跌-3.1%，同期Wind全A上涨5.8%，结构上仅银行板块一枝独秀（+13.1%），其余如 煤炭、石油石化、建筑装饰、交通运输、公用事业等股息较高的行业普遍下跌，但7月后随着中央财经 委会议明确提出"反内卷"政策，工信部计划实施新一轮钢铁、有色金属、石化、建材等十大重点行业稳 增长工作方案，以及雅江水电万亿基建工程需求刺激等利好因素共振，商品价格自6月底以来开始快速 上涨，带动行业景气显著回升，与周期相关的高股息板块表现突出，反而前期涨幅较大的银行板块出现 连日回调。 （3）银行股息率短期维持震荡，中长期依然看好红利资产的配置价值 对于近期银行股息率的大幅下降，主要原因在于银行个股自身的分红节奏，板块近12个月滚动累计分红 金额边际大幅下降，在分子端对股息率形成较大下降压力。不过银行板块股息率因分子端影响而下降的 过程基本结束。7月21日至8月份，银行板块近12个月滚动分红金额预计只会微幅减少7.7亿元左右，对 近12个月的股息率在分子端的影响可忽略不计。而且从历史案例来看，参考中 ...
