What is Cluster Buying?

Cluster buying occurs when multiple corporate insiders purchase shares of their company within a short time window. This pattern is considered one of the strongest signals of insider confidence.

When three or more executives independently decide to buy shares around the same time, it suggests they collectively believe the stock is undervalued. Research shows that cluster buys with CEO or CFO participation tend to have even stronger predictive value.
