Filings by Jonathan Silverstein span 6 companies, the busiest being GLAUKOS Corp, Arcutis Biotherapeutics, Inc. and Audentes Therapeutics, Inc. The record holds 68 filings, for trades running from 25 July 2016 to 2 October 2020.

Both buying and selling appear: 6 purchases worth €26.0M, against 48 sales worth €90.4M. Netting one side against the other leaves €64.4M of net selling. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. So far in 2020, the count stands at 4 purchases and no sales.

The median purchase comes to €5.1M. On 6 out of 6 purchases, another insider of the same company was buying within the same 30 days. Purchases made close together by different insiders form what is called a cluster. Looking at 5 purchases old enough to measure, the stock rose over the following 90 days in 80% of cases; the median change was +1.4%. These figures describe past trades and do not predict future prices.

The record was last updated on 6 October 2020 with an open-market purchase (€4.3M) in Arcutis Biotherapeutics, Inc. The median gap between a trade and its publication by SEC (Form 4) is 1 day. The legal deadline for a Form 4 is two business days after the transaction. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
