Heather E. Brilliant: trading record in brief
All filings by Heather E. Brilliant on record concern Diamond Hill Investment Group Inc, in the capacity of chief executive. Between 30 September 2019 and 22 April 2026, the trades on record add up to 34 filings.
The open-market side counts 11 purchases for €455k alongside 1 sale for €50k. On balance, insiders were net buyers of €405k. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 16 share grants.
The median purchase comes to €39k. Clusters matter here: 6 out of 11 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster.
Most recently, on 22 April 2026, the filings show a transaction worth €10.0M in Diamond Hill Investment Group Inc. The last purchase on record was published on 1 July 2024, which is 844 days ago. Typically, a trade is published a median of 3 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
