# A股动量策略/反转效应分析助手 ## 数据获取 通过 cn-stock-data skill 获取数据: - **K线数据**: 日线(至少 18 个月历史),用于计算多周期动量 - **实时行情**: quote 接口获取最新价格、成交量、换手率 - **行业分类**: 申万一级行业,用于行业动量分析 ## 分析工作流 ### Step 1: 多周期动量计算 - **1M 动量** (20 交易日): 短期反转信号,A股 1-4 周普遍存在反转效应 - **3M 动量** (60 交易日): 中短期过渡区间 - **6M 动量** (120 交易日): 中期动量核心区间,A股动量效应最显著 - **12M 动量** (250 交易日): 长期动量,需剔除最近 1 个月(skip-month) - 动量得分 = (当前价 - N日前价) / N日前价 * 100% - 计算时剔除 ST、停牌超 10 日、上市不足 1 年的股票 ### Step 2: 构建多空组合 - 按动量得分排序,分为 5 组 (quintile) - Q1 = 最低动量(输家组),Q5 = 最高动量(赢家组) - 多头组合: Q5(做多赢家);空头组合: Q1(做多输家) - Long-Short = Q5 - Q1,衡量动量因子溢价 - 计算各组合等权收益率、持有期收益 ### Step 3: A股特有模式分析 - **短期反转** (1-4 周): A股散户占比高,过度反应后回归,反转效应显著 - **中期动量** (3-12 月): 信息扩散慢 + 机构调仓惯性,动量效应存在但弱于美股 - **长期反转** (12-36 月): 均值回归,长期输家跑赢赢家 - **成交量交互**: 高换手率股票动量衰减更快;低换手 + 高动量信号更持久 - **涨跌停效应**: 连板股的短期惯性 vs 打开涨停后的反转 ### Step 4: 行业动量 vs 个股动量 - 行业动量: 按申万一级行业计算行业指数动量,行业轮动信号 - 个股动量: 行业中性化后的残差动量 (residual momentum) - 残差动量 = 个股收益 - 行业平均收益,剥离行业 beta - 行业动量持续性通常强于个股动量 ### Step 5: 风险与崩溃分析 - **动量崩溃** (momentum crash): 市场反转时动量组合大幅回撤 - 牛熊转换期动量策略风险最大,需监控市场状态 - 波动率调整: 高波动时降低动量仓位 - 最大回撤、Sharpe ratio、Calmar ratio ### Step 6: 输出报告 ## 输出格式 ### formal 风格(研报级) ``` # [标的/市场] 动量策略分析报告 ## 一、动量因子概览 | 周期 | 动量得分 | 分位数 | 信号 | |------|---------|--------|------| | 1M | -3.2% | P25 | 短期反转买入 | | 6M | +18.5% | P82 | 中期动量持续 | ## 二、多空组合表现 [各 quintile 组合收益率表格,Long-Short 收益] ## 三、A股动量特征 [短期反转 vs 中期动量分析,成交量交互] ## 四、行业动量轮动 [行业动量排名,残差动量 Top/Bottom 10] ## 五、风险提示 [动量崩溃风险、当前市场状态评估] ## 六、策略建议 [具体操作建议、仓位管理] ``` ### brief 风格(快速分析) ``` ## [标的] 动量速览 - 6M 动量 +18.5% (P82),中期趋势向上 - 1M 反转信号:超跌 -3.2%,短期存在反弹机会 - 行业动量排名:电子 #3/31 - 残差动量 +5.2%,个股 alpha 为正 - 风险:市场波动率偏高,建议半仓 ``` ## 回测脚本 使用 `scripts/momentum_backtest.py` 进行历史回测: ```bash python scripts/momentum_backtest.py --data kline.json --lookback 120 --holding 20 ``` 参考 `references/momentum-guide.md` 获取动量异象理论与 A股实证研究。
