Mark D. Klein: trading record in brief
This profile gathers the share dealings of Mark D. Klein in Neostellar Capital Corp., where the filings describe the role as chief executive. The record holds 35 filings, for trades running from 10 May 2021 to 21 September 2026.
The open-market record is one-sided, with 18 purchases worth €971k and not one sale.

In size, the median ticket on the buying side is €43k. 4 out of 18 purchases came within 30 days of a purchase by at least one other insider of the same company. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.
The latest filing, published on 22 September 2026, reports an open-market purchase of €34k in Neostellar Capital Corp. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. US insiders must file a Form 4 within two business days of a trade. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
