Vatera Healthcare Partners LLC

Vatera Healthcare Partners LLC discloses dealings in Cempra, Inc. to SEC (Form 4). Over a trading history stretching from 5 January 2018 to 29 May 2018, the count stands at 6 filings.

Purchases make up the whole of the open-market record (6 purchases, €165.4M). Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay.

In size, the median ticket on the buying side is €27.4M. On 2 out of 4 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.

The latest filing, published on 31 May 2018, reports an open-market purchase of €32.5M in Cempra, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. Section 16 rules allow two business days to file each Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
