John A. Bartholdson: trading record in brief
Filings by John A. Bartholdson span 2 companies, the busiest being Bioventus Inc. and Lincoln Educational Services Corp. The record holds 23 filings, for trades running from 6 May 2021 to 2 June 2026.
Both buying and selling appear: 8 purchases worth €5.2M, against 4 sales worth €5.2M. On balance, insiders were net buyers of €36k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 5 share grants and 6 option exercises.
The median purchase comes to €500k. On 4 out of 8 purchases, another insider of the same company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster.
The newest entry dates from 4 June 2026: an option exercise, in Bioventus Inc. The latest purchase dates back some time: it was published 789 days ago, on 20 August 2024. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. Section 16 rules allow two business days to file each Form 4. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
