Analysis of eligible SEC Form 4 activity for AMT indicates a bearish 30-day signal. The selected window contains transactions from 2 distinct reporting insiders, with aggregate nominal activity of $1.20M.
Open-market purchases minus open-market sales produce a negative net flow of $1.20M. 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 Meyer Robert Joseph (SVP & Advisor to the CFO). Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
