Fred A. Middleton

This profile gathers the share dealings of Fred A. Middleton across 3 companies, led by Chimerix Inc, CalciMedica, Inc. and Endocyte Inc. We count 19 filings; the first trade dates from 15 January 2016 and the latest from 25 June 2026.

No open-market sale appears; the market trades are 16 purchases worth €1.1M. The amount is not disclosed for 3 filings. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The rest of the record consists of 1 share grant. Since January 2026: 1 purchase and no sales on the market.

In size, the median ticket on the buying side is €20k. Clusters matter here: 6 out of 16 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster. After 4 purchases with a full 90-day history, the hit rate stands at 0% and the median 90-day move at -34.7%. Past outcomes like these are no guarantee of what comes next.

The latest filing, published on 29 June 2026, reports an open-market purchase in CalciMedica, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
