Catherine M. Szyman: trading record in brief

Catherine M. Szyman, listed as board member, has filed trades across 5 companies (mainly through SEC (Form 4)), most often in Edwards Lifesciences Corp, Medtronic Inc and Inari Medical, Inc. In total, 218 filings cover trades dated from 10 July 2008 to 11 March 2026.

In open-market terms, that means 3 purchases worth €1.5M on one side and 90 sales worth €43.5M on the other. Taken together, the sales exceed the purchases by €42.0M. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Other entries cover 67 share grants and 52 option exercises.

In size, the median ticket on the buying side is €484k. On 3 out of 3 purchases, another insider of the same company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

The record was last updated on 16 March 2026 with a share grant (€162k) in Masimo Corp. The last insider purchase was made public on 27 May 2020, 2,356 days ago. Filings reach the SEC (Form 4) feed a median of 1 day after the trade. US insiders must file a Form 4 within two business days of a trade. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
