A typical purchase (the median) is worth €4.0M. Clusters matter here: 32 out of 32 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster. After 5 purchases with a full 90-day history, the hit rate stands at 80% and the median 90-day move at +26.5%. This is a record of the past, not a forecast.

On 4 January 2019 came the latest disclosure, a share grant for €8,505 in Senseonics Holdings, Inc. The latest purchase dates back some time: it was published 2,966 days ago, on 10 September 2018.
