Martin J. Schroeter

Martin J. Schroeter (chief executive) discloses dealings in 2 companies, chiefly Kyndryl Holdings, Inc. and International Business Machines Corp. We count 28 filings; the first trade dates from 1 February 2016 and the latest from 1 August 2026.

On the market, this insider has only ever bought: 3 purchases, €2.9M in total. 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 23 share grants and 1 option exercise.

Half of the purchases are above €916k and half below. 3 out of 3 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase.

Most recently, on 4 August 2026, the filings show a share grant worth €517k in Kyndryl Holdings, Inc. The latest purchase dates back some time: it was published 1,439 days ago, on 9 November 2022. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. 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.
