Both buying and selling appear: 2 purchases worth €28k, against 3 sales worth €56k. On balance, insiders were net sellers of €28k.

The record was last updated on 8 December 2015 with a transaction (€6.1M) in Markwest Energy Partners L P. The clock since the last published purchase (22 March 2010) now reads 6,059 days. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 4 days. US insiders must file a Form 4 within two business days of a trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
