This profile gathers the share dealings of Robert Willett across 3 companies, led by Cognex Corp, Clean Harbors Inc and Allegro Microsystems, Inc. Over a trading history stretching from 3 June 2021 to 20 May 2026, the count stands at 16 filings.

No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.

Most recently, on 22 May 2026, the filings show a share grant in Clean Harbors Inc. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
