$2.0MAnalysis of eligible SEC Form 4 activity for IBKR indicates a bearish 180-day signal. The selected window contains transactions from 7 distinct reporting insiders, with aggregate nominal activity of $106.77M.
Open-market purchases minus open-market sales produce a negative net flow of $1.99M. Compensation-related awards and option exercises represent more nominal activity than directional open-market trades, so the signal should be interpreted cautiously.
Conkling Lori A recorded the largest aggregate purchase volume, while Harris Lawrence E recorded the largest aggregate sale volume. Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
