MPM Bio Ventures I LLC

MPM Bio Ventures I LLC is a declared insider of Viacell Inc, with filings sourced from SEC (Form 4). In total, 7 filings cover trades dated 9 November 2007.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

Most recently, on 20 November 2007, the filings show a transaction worth €24.8M in Viacell Inc. Typically, a trade is published a median of 11 days after it takes place. 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.
