Market trades split into 7 purchases (€390k) and 34 sales (€6.1M). No amount is published for 4 filings, which the totals therefore leave out. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 12 option exercises. In 2026 alone, the filings show no purchases and 12 sales.

In size, the median ticket on the buying side is €54k. Clusters matter here: 1 out of 7 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster.

Most recently, on 17 August 2026, the filings show an open-market sale worth €66k in 908 Devices Inc. The last insider purchase was made public on 19 May 2025, 517 days ago. Typically, a trade is published a median of 2 days after it takes place. The legal deadline for a Form 4 is two business days after the transaction. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
