Analysis of eligible SEC Form 4 activity for TMO indicates a bearish 365-day signal. The selected window contains transactions from 20 distinct reporting insiders, with aggregate nominal activity of $232.75M.
Open-market purchases minus open-market sales produce a negative net flow of $158.13M. Open-market executions represent the majority of measured nominal activity in this window, making the directional flow more representative of voluntary trading activity.
The largest open-market sale in the selected window was attributed to CASPER MARC N (Director, Chairman & CEO). Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
