Robert Robotti: trading record in brief
Filings by Robert Robotti span 3 companies, the busiest being Tidewater Inc, Amrep Corp. and PHX Minerals Inc. We count 75 filings; the first trade dates from 31 December 2015 and the latest from 16 September 2026.
The open-market side counts 35 purchases for €32.9M alongside 11 sales for €19.2M. On balance, insiders were net buyers of €13.7M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Other entries cover 25 share grants. In 2026 alone, the filings show no purchases and 4 sales.
In size, the median ticket on the buying side is €59k. Clusters matter here: 3 out of 32 purchases overlapped with buying by a colleague within 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.
The newest entry dates from 18 September 2026: an open-market sale of €521k, in Tidewater Inc. The last insider purchase was made public on 5 June 2025, 500 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
