Nina S. Kjellson

This profile gathers the share dealings of Nina S. Kjellson across 4 companies, led by Tyra Biosciences, Inc., Ocera Therapeutics, Inc. and Trius Therapeutics Inc. In total, 40 filings cover trades dated from 6 August 2010 to 5 February 2025.

In open-market terms, that means 4 purchases worth €9.6M on one side and 26 sales worth €4.1M on the other. The totals do not cover 1 filing with an undisclosed amount. 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 2 share grants. Since January 2025: no purchases and 8 sales on the market.

Half of the purchases are above €3.0M and half below.

On 7 February 2025 came the latest disclosure, an open-market sale for €47k in Tyra Biosciences, Inc. The latest purchase dates back some time: it was published 4,203 days ago, on 22 April 2015. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
