Mary Celeste Fruge: trading record in brief
Mary Celeste Fruge is a declared insider of NPK International Inc., with filings sourced from SEC (Form 4). We count 11 filings; the first trade dates from 1 June 2023 and the latest from 19 May 2026.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.
The record was last updated on 21 May 2026 with a share grant in NPK International Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
