Atlas Venture Fund V LP

Atlas Venture Fund V LP has filed trades across 4 companies (mainly through SEC (Form 4)), most often in Isilon Systems, Inc., Alnylam Pharmaceuticals, Inc. and Helicos Biosciences Corp. The record holds 54 filings, for trades running from 23 February 2006 to 17 December 2010.

In open-market terms, that means 12 purchases worth €3.0M on one side and 34 sales worth €32.5M on the other. The totals do not cover 2 filings with an undisclosed amount. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Since January 2010: no purchases and 18 sales on the market.

In size, the median ticket on the buying side is €96k.

On 21 December 2010 came the latest disclosure, a transaction for €327.7M in Isilon Systems, Inc. The last purchase on record was published on 22 September 2009, which is 6,241 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. US insiders must file a Form 4 within two business days of a trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
