The Insider Filing Data Feed (IFDF) is designed to capture all U.S. insider activity as reported on Forms 3, 4, 5, and 144 in line-by-line detail. In addition, a unique cleansing process is used by Thomson Reuters that makes systematic interpretations on the accuracy of as-reported data and inserts "cleansed" fields for comparison. A cleanse code is also included to denote the overall level of confidence in each record. Additionally, the Insider Filing Data Feed includes performance calculations revealing which insiders' prior trades have been most predictive of subsequent stock returns.
