No open-market sales in 30DAnalysis of eligible SEC Form 4 activity for IBKR indicates a bullish 30-day signal. The selected window contains transactions from 2 distinct reporting insiders, with aggregate nominal activity of $70.71M.
Open-market purchases minus open-market sales produce a positive net flow of $0.00M. 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 purchase in the selected window was attributed to Conkling Lori A. Form 4 activity provides useful ownership context, but it should not be treated as a standalone prediction of future price performance.
