Corporate insiders have to report buying their own stock within two business days. One in four files the same day: a Same-day buy.When two other insiders at the same company have already bought in the ten trading days before: a Cluster buy.Two kinds of alert, the Same-day alert and the Cluster alert, sent straight to you by email and push within minutes of the SEC accepting the filing, each tracked in its own live portfolio on the dashboard.

Open-market buys of $100,000 or more by officers and directors of NYSE and Nasdaq companies, reported on the day of the trade. In our backtest of 2017 to 2026, held for 63 trading days: 22.2% annualised. Roughly 25 to 35 Same-day alerts a month, in waves: busy in the weeks after quarterly results, quiet in the weeks before.

A same-day insider buy at a company where two other officers or directors have already bought their own stock, with their own money, in the ten trading days before. In the same backtest, January 2017 to September 2026, 343 alerts held for 63 trading days returned 71.3% annualised. Our qualified cluster buys come to two or three a month on average, and some months have none. That is a number you can keep up with. Each one is sent as a Cluster alert and tracked in its own portfolio.

We read every new SEC filing as it is accepted. A qualifying filing is on the dashboard and in your inbox within minutes, as a Same-day alert or a Cluster alert.

Every alert, Same-day and Cluster, becomes a position in the Same-day portfolio, because a cluster buy is a same-day buy first: the same filing, the same rules, with two earlier buyers behind it. That keeps the Same-day portfolio the complete record of every qualifying buy. Every cluster buy also enters the Cluster portfolio, so the three-insider signal can be seen on its own. Both portfolios work the same way: entry at the next regular-session opening price after the filing, closed after 63 trading days (three months), with a sell signal the day before.
