Robert M. Buck: trading record in brief
This profile gathers the share dealings of Robert M. Buck across 2 companies, led by TopBuild Corp and Core & Main, Inc. In total, 28 filings cover trades dated from 14 January 2016 to 1 July 2026.
On the market, this insider has only sold: 11 sales, €14.9M in total. The rest of the record consists of 14 share grants.
The record was last updated on 1 July 2026 with a transaction in TopBuild Corp. 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. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
