Filings by Sarah E. Hlavinka span 4 companies, the busiest being Quanterix Corp, Itron, Inc. and ODP Corp. Between 21 February 2019 and 10 December 2025, the trades on record add up to 66 filings.

In open-market terms, that means 3 purchases worth €147k on one side and 9 sales worth €839k on the other. On balance, insiders were net sellers of €692k. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The rest of the record consists of 50 share grants and 2 option exercises.

The median purchase comes to €49k. Of 3 purchases, 2 formed part of a group of insiders buying within 30 days of each other. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

The newest entry dates from 10 December 2025: a transaction of €733k, in ODP Corp. The last purchase on record was published on 9 November 2022, which is 1,445 days ago. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
