A股自相关/序列相关性分析

SkillDev tools

A-share autocorrelation / serial correlation / return autocorrelation structure analysis. Triggered when the user says "自相关", "autocorrelation", "序列相关", "收益率预测性", "动量还是反转", "自相关系数", "ACF", "PACF", "Ljung-Box", "收益率是否可预测", or "随机游走检验". MUST USE when user asks about return autocorrelation, serial corr

Workflow

Step 1: 获取K线收益率序列

Step 2: 计算自相关函数(ACF)

lag 1-20的自相关系数

Step 3: 偏自相关函数(PACF)

Step 4: Ljung-Box检验

检验序列是否存在显著自相关

Step 5: 输出

维度formalbrief
ACF/PACF完整图表关键lag
检验LB统计量+p值有无自相关
含义动量/反转判断交易含义
默认风格:brief。

关键规则

  1. 正自相关=动量效应(涨了还会涨)
  2. 负自相关=反转效应(涨了会跌回)
  3. A股日频负自相关较明显(T+1导致的隔日反转)
  4. 周频/月频正自相关更显著(中期动量)
  5. 自相关结构是时间序列策略的基础

使用示例

示例 1: 基本使用

# 调用 skill
result = run_skill({
    "param1": "value1",
    "param2": "value2"
})

示例 2: 命令行使用

python scripts/run_skill.py --input data.json
