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。

买入规模+7.9 / 25

角色+20.0 / 20

近期性+4.1 / 10

确信度+10.0 / 10

哪些因素限制了当前分数？

⚠ Cluster breadth is moderate · 3 insider(s), not 4+
⚠ Purchase size is modest relative to the model scale
✓ 角色得分高 · 买入者中职位最高的是：Director

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。
