Insider Activity Analysis

This page provides a comprehensive view of insider trading activity at Adaptive Biotechnologies Corp (ADPT). Every SEC Form 4 filing by Adaptive Biotechnologies Corp executives, directors, and 10% beneficial owners is processed and analyzed by InsiderCompass to surface the transactions that matter most: discretionary open-market purchases where insiders are putting their own money at risk.

InsiderCompass monitors all SEC Form 4 insider trading filings for Adaptive Biotechnologies Corp (ADPT) to identify meaningful buying and selling patterns. Each transaction is analyzed to determine whether it represents a discretionary investment decision or routine equity compensation activity. This distinction is critical because discretionary purchases, where insiders use their own capital to buy shares on the open market, carry significantly more informational value than automatic option exercises or planned 10b5-1 sales.

InsiderCompass processes SEC Form 4 filings daily to track insider trading activity. Each transaction is classified as discretionary or non-discretionary based on transaction codes, footnote analysis, and 10b5-1 plan indicators. Discretionary open-market purchases (transaction code P) carry the strongest informational signal because they represent an insider choosing to invest their own capital at the current market price.

Cluster buying detection is one of InsiderCompass's core analytical features. When two or more insiders at the same company purchase shares within a seven-day sliding window with combined value exceeding $50,000, it triggers a cluster alert. Academic research has consistently shown that cluster insider buying events tend to precede above-average stock returns, making them one of the most reliable insider trading signals available.
