Michael J. Koss: trading record in brief
Michael J. Koss, listed as chief executive, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Koss Corp and Strattec Security Corp. Over a trading history stretching from 17 January 2006 to 17 February 2026, the count stands at 126 filings.
Both buying and selling appear: 40 purchases worth €103k, against 41 sales worth €21.2M. Netting one side against the other leaves €21.1M of net selling. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Other entries cover 15 share grants and 14 option exercises.
A typical purchase (the median) is worth €1,064. No cluster: in 5 purchases, no other insider of the company bought within 30 days. Ninety days after publication, 40 purchases show a median change of +23.6%, with the price up in 68% of them. Past outcomes like these are no guarantee of what comes next.
The record was last updated on 17 February 2026 with a transaction in Koss Corp. The clock since the last published purchase (19 May 2017) now reads 3,460 days. Typically, a trade is published a median of 2 days after it takes place. Section 16 rules allow two business days to file each Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
