Insider Trading Chart

Insider Roster and Profitability Metrics

This table shows the list known insiders, and is generated automatically from filings disclosed to the SEC. In addition to the names, most recent title, and director, officer, or 10% owner designation, we provide the latest disclosed holdings. Additionally, when possible we provide the historical trade performance for the insider. The historical trade performance is a weighted average of the performance of actual open-market purchase transactions made by the insider. For more information on how this is calculated, watch this YouTube webinar.
