内部人士情绪分数
“内部人士情绪分数”用于查找被公司内部人士购入的公司。
它是一个复杂的多因素量化模型的结果，该模型能够辨识具有最高内部人士累积持有水平的公司。该评分模型结合了内部人士在过去90天内买入的净数量、总买入股份占流通股比例，以及内部人士拥有的总股份的指标。该分数的范围从0到100，数值越高表示相对于同行业而言具有更高程度的内部人士持股水平，50为平均值。

高管情绪分数
“高管情绪分数”用于查找被公司管理层购入的公司。
根据定义，公司高管是公司内部人士，但与其他内部人士（10%的股东和董事会成员）不同，公司高管每天在公司工作，而且他们使用自己的资金进行交易。（10%的股东和董事会成员通常是基金经理，管理着其他人的资金。）因此，公司高管进行的内幕交易更为重要，应该被适当地重视和关注。
如同“内部人士情绪分数”，“高管情绪分数”也是一个复杂的多因素量化模型的计算结果，该模型能够辨识具有最高高管累积持有水平的公司。

关键内部人士指标
此表格显示了公司在各种内部人士指标上的排名。百分位数排名显示了这家公司在美国市场与其他公司相比的表现。排名越高表明公司所处状况越好。
举例来说，一般认为内部人士的买入是一个积极的指标，因此具有更多内部人士买入的公司将排名高于那些内部人士买入较少（甚至有内部人士卖出）的公司。
内幕交易图表
以下图表显示了Gentex Corporation内部人士交易。内部人士包括公司的高管、董事或重要投资者。一般而言，基于内幕、非公开信息进行交易是非法的。这并不意味着他们在自己的公司进行任何交易都是非法的。但是，他们必须通过Form 4向美国证券交易委员会（SEC）报告所有交易。
内部人员名单及盈利指标
这张表格显示已知的内部人士名单，从向美国证券交易委员会（SEC）披露的申报文件中自动生成。除了姓名、当前职位和董事、高管或10%所有人的任命外，我们还提供了最新披露的持股信息。此外，我们尽可能提供内部人士的历史交易表现。历史交易表现是内部人士实际进行的公开市场买入交易表现的加权平均值。有关此计算方式的更多信息，请查看YouTube网络研讨会。
