When 3+ distinct insiders buy the same stock within a rolling window, it's flagged as a cluster.
A single insider buying stock could mean anything — a scheduled purchase plan, tax optimization, or genuine conviction. But when multiple executives at the same company start buying with their own money within days of each other, the signal is stronger.
Academic research consistently shows that insider buying clusters are among the most reliable predictive signals in equity markets. These aren't analysts guessing — they're the people who see the quarterly numbers before anyone else.
