William A. Koefoed: trading record in brief
This profile gathers the share dealings of William A. Koefoed across 2 companies, led by OneStream, Inc. and Bank of the Ozarks Inc. The record holds 25 filings, for trades running from 18 May 2015 to 15 December 2025.
On the open market, the record shows 1 purchase worth €37k and 12 sales worth €3.7M. The net balance comes to €3.6M on the selling side. 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 6 share grants and 6 option exercises. So far in 2025, the count stands at no purchases and 9 sales.
On 16 December 2025 came the latest disclosure, an open-market sale for €145k in OneStream, Inc. The last insider purchase was made public on 29 April 2016, 3,845 days ago. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
