Richard Nigon

Richard Nigon, listed as board member, has filed trades across 4 companies (mainly through SEC (Form 4)), most often in Tactile Systems Technology Inc, Celcuity Inc. and Northern Technologies International Corp. Between 10 February 2016 and 1 September 2026, the trades on record add up to 36 filings.

Both buying and selling appear: 4 purchases worth €399k, against 6 sales worth €1.3M. Netting one side against the other leaves €891k of net selling. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Outside the open market, there are 18 share grants and 5 option exercises. In 2026 alone, the filings show no purchases and 1 sale.

The median purchase comes to €104k.

The latest filing, published on 3 September 2026, reports a share grant in Northern Technologies International Corp. The most recent open-market purchase was published on 13 September 2022, 1,499 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. The legal deadline for a Form 4 is two business days after the transaction. 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.
