内部人信号

65.1 / 100

2 位买方 · 22 条买入交易行 · $109.2M 买入总额

为什么有这个信号？

买方广度较低
买入规模较强
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+14.0 / 35
买入规模+24.7 / 25
角色+14.0 / 20
近期性+2.7 / 10
确信度+9.8 / 10

哪些因素限制了当前分数？

  • ⚠ Cluster breadth is moderate · 2 insider(s), not 4+
  • ⚠ 角色得分低 · 买入者中职位最高的是：TenPercentOwner（CEO、董事长和持股 10% 以上的股东得分最低）
  • ⚠ Purchase activity is becoming less recent

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。
