John E. Harper: trading record in brief
John E. Harper, listed as senior executive, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Kronos Worldwide Inc and NL Industries Inc. We count 12 filings; the first trade dates from 19 May 2021 and the latest from 14 May 2026.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.
The record was last updated on 15 May 2026 with a share grant (€34k) in NL Industries Inc. Typically, a trade is published a median of 1 day after it takes place. The legal deadline for a Form 4 is two business days after the transaction. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
