George Massaro: trading record in brief

George Massaro (board member) discloses dealings in 2 companies, chiefly Charles River Laboratories International, Inc. and Huron Consulting Group Inc. Over a trading history stretching from 4 January 2016 to 15 May 2025, the count stands at 14 filings.

No open-market purchase appears, only 9 sales worth €544k. No amount is published for 2 filings, which the totals therefore leave out. The rest of the record consists of 4 share grants. So far in 2025, the count stands at no purchases and 2 sales.

The newest entry dates from 16 May 2025: an open-market sale of €4,263, in Charles River Laboratories International, Inc. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
