内部人信号

77.0 / 100

5 位买方 · 5 条买入交易行 · $1.0M 买入总额

为什么有这个信号？

买方广度较强
买入规模中等
角色中等
近期性较低
确信度较强
评分构成

每条进度条表示其对当前分数的贡献；权重和公式保持不变。

Cluster+35.0 / 35
买入规模+17.6 / 25
角色+13.0 / 20
近期性+1.5 / 10
确信度+10.0 / 10

哪些因素限制了当前分数？

  • ⚠ 角色得分低 · 买入者中职位最高的是：President and CEO（CEO、董事长和持股 10% 以上的股东得分最低）
  • ⚠ Purchase activity is becoming less recent
  • ✓ Cluster breadth is broad · 4+ insiders

Purchase-size comments are relative to the model scale. Average daily volume is a separate market-context diagnostic.

US-v1.2 按当前 180 天规则给合资格的股票买入打分。分数只表示研究的先后，不是收益预测或概率。回测没有显示美国分数越高、之后的表现越好。
