The open-market side counts 6 purchases for €213k alongside 10 sales for €2.4M. Sales outweigh purchases by €2.2M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Besides market trades, the filings include 16 share grants and 7 option exercises.

The median purchase comes to €33k. Ninety days after publication, 4 purchases show a median change of +8.6%, with the price up in 75% of them. They describe history only and say nothing certain about the share price ahead.

The record was last updated on 20 May 2015 with a share grant (€17k) in Rogers Corp. The last insider purchase was made public on 31 July 2014, 4,467 days ago. The median gap between a trade and its publication by SEC (Form 4) is 1 day. The legal deadline for a Form 4 is two business days after the transaction. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
