$5.0MAnalysis of eligible SEC Form 4 activity for SEIC indicates a bearish 90-day signal. The selected window contains transactions from 9 distinct reporting insiders, with aggregate nominal activity of $23.51M.
Open-market purchases minus open-market sales produce a negative net flow of $16.75M. 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 WEST ALFRED P JR (Chairman Emeritus). Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
