All filings by Michael A. Hartmann on record concern BioAmber Inc. In total, 4 filings cover trades dated from 5 May 2016 to 18 August 2017.

On the market, this insider has only ever bought: 4 purchases, €13k in total. The totals exclude 1 filing filed without an amount. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. 2017 to date brings 2 purchases and no sales.

A typical purchase (the median) is worth €4,054. Clusters matter here: 1 out of 3 purchases overlapped with buying by a colleague within 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time.

The latest filing, published on 22 August 2017, reports an open-market purchase of €4,054 in BioAmber Inc. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. 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.
