William A. Zartler: trading record in brief
Filings by William A. Zartler span 2 companies, the busiest being Aris Water Solutions, Inc. and Solaris Energy Infrastructure, Inc. We count 32 filings; the first trade dates from 26 October 2021 and the latest from 1 March 2026.
The open-market side counts 8 purchases for €1.2M alongside 1 sale for €205k. The net balance comes to €963k on the buying side. 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 22 share grants.
Half of the purchases are above €149k and half below. Clusters matter here: 2 out of 7 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.
The newest entry dates from 3 March 2026: a share grant, in Solaris Energy Infrastructure, Inc. The most recent open-market purchase was published on 9 September 2025, 404 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. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
