InsiderAct tracks four signal types: cluster buying (2+ insiders buying within 7–14 days), large insider purchases ($100k+ open-market buys), buying the dip (purchases after notable price declines), and blue-chip insider buying (purchases at large-cap companies). All signals are derived exclusively from public SEC Form 4 filings.
Form 4 covers many transaction types including option exercises, awards, and automatic plan sales — none of which reflect a deliberate investment decision. Open-market purchases (Form 4 code "P") are the only transaction type where an insider voluntarily spends personal cash on their company's stock. This discretionary commitment is what makes them informative as a signal.
A cluster buy signal occurs when two or more corporate insiders independently purchase shares within a 7–14 day window. It is considered one of the strongest publicly available insider trading signals because it requires multiple independent decision-makers to share the same bullish conviction at the same time, making it unlikely to be coincidental.
InsiderAct detects buying-the-dip signals by identifying open-market insider purchases (Form 4 code "P") made while the company's stock price has declined by a significant amount over recent weeks. The signal combines price context with insider conviction — an insider buying at a lower price is explicitly expressing confidence that the decline is temporary.
