$15.3KAnalysis of eligible SEC Form 4 activity for SON indicates a bullish 180-day signal. The selected window contains transactions from 20 distinct reporting insiders, with aggregate nominal activity of $4.73M.
Open-market purchases minus open-market sales produce a positive net flow of $0.97M. Compensation-related awards and option exercises represent more nominal activity than directional open-market trades, so the signal should be interpreted cautiously.
Joachimczyk Paul recorded the largest aggregate purchase volume, while Florence John M 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.
