About WIERENGA WENDELL

This profile aggregates every SEC Form 4 insider transaction reported by WIERENGA WENDELL across all companies they trade. Open-market purchases (code P) and sales (code S) are the highest-signal, discretionary trades; grants (A), option exercises (M) and gifts (G) reflect compensation rather than conviction and carry no market price. Figures cover the selected period and update as new filings are ingested.
