What is ClusterSignal?

ClusterSignal detects when two or more insiders — the CEO, CFO, or a company's directors — buy shares of their own company's stock within the same 21-day window. The underlying data comes straight from public filings: SEC Form 4 in the US, SEDI in Canada.

When a cluster is detected, ClusterSignal scores it automatically on a 0-10 scale so you can prioritize which ones are worth a closer look, then sends an email and push notification. A public results page shows real historical alert outcomes, and a glossary explains the filing terminology in plain language.

This is research software for individual investors who do their own due diligence — it surfaces a specific, publicly-disclosed filing pattern and leaves every investment decision to you. $11.99/month, 14-day free trial. A sister product, PennySignal, applies the same detection to penny stocks.
