$47.5KAnalysis of eligible SEC Form 4 activity for AMCX indicates a bearish 180-day signal. The selected window contains transactions from 15 distinct reporting insiders, with aggregate nominal activity of $1.73M.
Open-market purchases minus open-market sales produce a negative net flow of $0.05M. 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 Sherin Michael J. III (EVP & Chief Accounting Officer). Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
