Signal history

John T. Kurtzweil: trading record in brief

John T. Kurtzweil, listed as board member, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Axcelis Technologies Inc and SkyWater Technology, Inc. Over a trading history stretching from 17 May 2021 to 20 May 2025, the count stands at 14 filings.

No open-market purchase appears, only 6 sales worth €1.1M. Besides market trades, the filings include 8 share grants. So far in 2025, the count stands at no purchases and 1 sale.

The latest filing, published on 21 May 2025, reports an open-market sale of €92k in Axcelis Technologies Inc. The median gap between a trade and its publication by SEC (Form 4) is 1 day. US insiders must file a Form 4 within two business days of a trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
