Kurt W. Briner

Kurt W. Briner discloses dealings in BioAmber Inc. to SEC (Form 4). Over a trading history stretching from 20 May 2016 to 15 August 2017, the count stands at 5 filings.

The open-market record is one-sided, with 5 purchases worth €106k and not one sale. No amount is published for 1 filing, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Since January 2017: 1 purchase and no sales on the market.

In size, the median ticket on the buying side is €32k. 3 out of 4 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster.

The latest filing, published on 16 August 2017, reports an open-market purchase in BioAmber Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
