Workflow

Step 1: 获取财务数据和K线

Step 2: 计算业绩超预期度

  • SUE = (实际EPS - 预期EPS) / |预期EPS|
  • 或用 实际净利润 vs 上期同比趋势线

Step 3: 事件效应分析

  • 业绩公告后T+1/T+3/T+5/T+20的CAR
  • 区分超预期和低预期的不对称效应

Step 4: 业绩漂移(PEAD)

分析业绩公告后的收益率漂移持续性

Step 5: 输出

维度formalbrief
超预期度SUE计算+排名超/达/低预期
市场反应CAR序列分析公告后涨跌
漂移分析PEAD统计漂移方向
默认风格:brief。

关键规则

  1. A股业绩漂移效应(PEAD)显著存在——超预期后继续涨
  2. 负面业绩反应通常比正面更剧烈(不对称效应)
  3. 业绩预告vs正式报告可能有差异——两次都需关注
  4. 分析师一致预期是衡量超预期的最佳基准(如有)
  5. 业绩公告通常盘后发布——T+1为首个反应日
