Both buying and selling appear: 4 purchases worth €375k, against 14 sales worth €7.3M. The net balance comes to €6.9M on the selling side. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Outside the open market, there are 31 share grants and 50 option exercises.

The median purchase comes to €77k. Clusters matter here: 3 out of 3 purchases overlapped with buying by a colleague within 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

Most recently, on 26 May 2023, the filings show an option exercise in Accelerate Diagnostics, Inc. The last insider purchase was made public on 30 November 2018, 2,884 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. 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.
