$570.2KAnalysis of eligible SEC Form 4 activity for VMC indicates a bearish 30-day signal. The selected window contains transactions from 2 distinct reporting insiders, with aggregate nominal activity of $45.26M.
Open-market purchases minus open-market sales produce a negative net flow of $0.57M. Compensation-related awards and option exercises represent more nominal activity than directional open-market trades, so the signal should be interpreted cautiously.
The largest open-market sale in the selected window was attributed to Clement David P. Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
