William G. Kistner

William G. Kistner is a declared insider of Byline Bancorp, Inc. (senior executive), with filings sourced from SEC (Form 4). Over a trading history stretching from 30 April 2019 to 19 August 2026, the count stands at 24 filings.

Purchases make up the whole of the open-market record (21 purchases, €235k). Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Besides market trades, the filings include 3 share grants. Since January 2026: 1 purchase and no sales on the market.

A typical purchase (the median) is worth €3,575. 12 out of 21 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. After 20 purchases with a full 90-day history, the hit rate stands at 70% and the median 90-day move at +3.4%. This is a record of the past, not a forecast.

The newest entry dates from 20 August 2026: an open-market purchase of €3,307, in Byline Bancorp, Inc. 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. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
