Insider Cluster

An insider cluster is several insiders at the same company buying on the open market inside a short window. One executive buying shares is worth a look. A handful of them buying together is a much stronger signal, and this view pulls those clusters out of the noise.

Several insiders buying the same name in a short window.

Why clusters matter

Insiders sell for all kinds of reasons, but they tend to buy for one: they think the stock is cheap. When officers and directors act alone, it's easy to read too much into it. When several of them step in around the same time, the shared conviction is harder to dismiss. They know the business better than the market does, and they're spending their own money.

What the view shows

Each entry groups the buys at one company: who bought, how much, and over what span of days. A tight cluster of meaningful purchases carries more weight than a few scattered token buys. From any entry you can open the full feed of that company's insider activity in the insider feed.

Using it

A cluster is a starting point, not a trade on its own. Check the size of the buys against each insider's history, look at where the stock sits, and weigh it against the rest of the picture. For a worked example of turning a cluster into an idea, see Trading insider conviction.
