数据源

SCRIPTS="$SKILLS_ROOT/cn-stock-data/scripts"
python "$SCRIPTS/cn_stock_data.py" kline --code [CODE] --freq daily --start [日期]

Workflow

Step 1: 获取多标的K线

Step 2: 交叉相关分析

计算标的A在t期收益率与标的B在t+k期收益率的相关性(k=-5到+5)

Step 3: Granger因果检验

检验A是否Granger因果引起B(或反向)

Step 4: 领先滞后图谱

构建多标的间的领先-滞后关系网络

Step 5: 输出

维度formalbrief
相关矩阵多lag完整矩阵最强领先关系
因果检验Granger检验结果领先/滞后天数
关系图谱完整网络图Top 3领先者
默认风格:brief。

关键规则

  1. 领先滞后关系可能不稳定——需滚动窗口验证
  2. 相关性≠因果——Granger检验也只是统计因果
  3. A股中上游→下游传导较明显(如铜→电线电缆)
  4. 大盘股往往领先小盘股1-2日
  5. 北向资金动向常领先A股1-3日
