评分构成

每条进度条是这一部分在总分里的分数，五项相加就是总分。

买入人数+21.0 / 35
买入金额+24.4 / 25
Buyers' roles+14.0 / 20
多近+9.5 / 10
买入与卖出+10.0 / 10

哪些因素限制了当前分数？

  • ⚠ 买入人数不多 · 3 位内部人，不到 4 位
  • ⚠ Buyers' roles add little · most senior buyer: TenPercentOwner（CEO、董事长和持股 10% 以上的股东得分最低）
  • ✓ 买入很近 · 最近一次在 2026-11-02

日均成交量在页面其他位置作为市场背景列出，不计入评分。

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。
